Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable automatic blood pressure monitor, and more particularly, it is suitable for blood pressure measurement such as in dialysis treatment where blood pressure must be measured frequently for a large number of patients. Regarding blood pressure monitor.

[0002]

2. Description of the Related Art In dialysis treatment, regular measurement of a patient's blood pressure is an important guideline for understanding the patient's condition. For example, if the number of patients is 50 and blood pressure is to be measured every 30 minutes during 4 hours of dialysis, the total number of times of measurement reaches 400 with only regular measurement. Furthermore, when a change in the patient's condition such as a decrease in blood pressure is observed, irregular and frequent blood pressure measurement is required.

On the other hand, at present, the most common method is to mount a mercury sphygmomanometer, which is a combination of a mercury column pressure gauge and a stethoscope, on a gantry with casters, convey it to the bed side, and settle it. Further, there has been proposed a device in which a dedicated automatic blood pressure monitor is provided for each bed (patient) and the blood pressure can be automatically measured without the assistance of a nurse (for example, Japanese Patent Laid-Open No. Sho 63-63).
No. 119977). Furthermore, the blood pressure of one patient
A portable sphygmomanometer is also proposed, which enables intermittent / continuous measurement at regular intervals for 24 hours (for example, Japanese Patent Laid-Open No. 2-55033).

[0004]

However, the conventional example having such a structure has the following problems. That is, the method using a general-purpose blood pressure monitor such as a mercury blood pressure monitor has the following disadvantages. (1) It is very troublesome to move many patients with a mercury sphygmomanometer between narrow beds,
It is also dangerous. (2) Since the measurement results must be recorded on paper one by one and transferred to a medical record later, the work of the nurse is very troublesome. (3) For listening to Korotkoff sounds and reading mercury columns,
Nerves must be concentrated many times, and skill is required for accurate blood pressure measurement. (4) The standard value of blood pressure differs for each patient. Therefore, the tendency from the start to the end of dialysis is more important than the individual measured values, but it takes time and effort to create it. (5) Such a sphygmomanometer cannot be always carried by hanging it around the neck or shoulder. Therefore, even if a patient whose blood pressure needs to be measured suddenly occurs in the middle of the round, the blood pressure monitor must be returned.

On the other hand, the example in which a dedicated blood pressure monitor is installed in each bed has the following disadvantages. (1) Although the time required to measure the blood pressure of each individual patient is not long, an expensive automatic blood pressure monitor must be installed for each bed, which increases equipment costs. (2) For a nurse, contact with a patient during dialysis is important not only for measuring blood pressure but also for maintaining communication with the dialysis patient. Therefore, even if the automatic sphygmomanometer is installed in all the beds, the round trip of the nurse is not necessary.

Further, the above-mentioned known portable sphygmomanometer for the purpose of intermittent and continuous measurement of a specific individual is not suitable for use in measuring a plurality of patients at arbitrary times. This is because the measurement data is stored for one set patient, and there is no mechanism for storing the patient identification (ID) code and the measurement result as a pair of data, so that different patients can be measured one after another. However, those data are stored as data of the same person, and it is not possible to determine later when and for which patient the measurement was performed. Therefore, before returning to the next patient's measurement, come back to the nurse station and
It is necessary to connect the main body to a personal computer through a separate analysis device, pay out the data inside the main body, and input the ID code of the next patient again into the main body. If the patient ID code is simply replaced at this time, the patient ID code measured up to that point is also changed. This is inconvenient for dialysis treatment.

The present invention has been made in view of such circumstances, and it is possible to measure the blood pressure for a large number of patients at any time, and the blood pressure measurement data can be distinguished once for each patient and then once. An object of the present invention is to provide a portable automatic sphygmomanometer that can be taken out.

[0008]

The present invention has the following constitution in order to achieve such an object. That is, the portable automatic sphygmomanometer according to the present invention, a cuff portion to be mounted on the measurement site, an air pump for supplying air to the cuff portion,
A pressure sensor for measuring the pressure of the cuff portion, a calculation means for calculating a blood pressure value from the measurement result of the pressure sensor, a display means for displaying the blood pressure value, a time means for measuring the blood pressure date and time, and an individual person to be measured. Identification code input means for inputting the identification code, storage means for storing the blood pressure value of each subject and the blood pressure measurement date and time in association with the identification code, and other contents stored in the storage means. And a transfer means for transferring to the storage medium.

Further preferably, in addition to the above-mentioned respective constitutions, the measurement time setting means for presetting the next measurement time of the person to be measured in association with the identification code, and the measurement time setting means are set. An alarm device that operates based on a command from the measurement time setting means when the time comes, the alarm device is operated by a command from the measurement time setting means, and the identification code of the person to be measured is displayed. Display it in the means.

[0010]

The operation of the present invention is as follows. That is,
The portable automatic sphygmomanometer according to claim 1 is always carried by a nurse or the like, and blood pressure is measured at any time and at any place. When measuring the blood pressure, the identification code unique to the person to be measured is input via the identification code input means. The blood pressure measurement data of the measurement subject output from the calculation means and the measurement date and time output from the timing means are stored in the storage means in association with the identification code. In this way, the blood pressure data and the measurement date and time of many measured persons are stored in the storage means in association with the identification code of each measured person.

After measuring the blood pressures of a large number of persons to be measured by regular rounds, the portable automatic blood pressure monitor according to the present invention is connected to, for example, a personal computer. Then, the blood pressure data of each subject and the measurement date and time are loaded into the personal computer together with their respective identification codes via the transfer means of the present apparatus. Each process performed by the personal computer is not particularly limited, but for example, the transition of blood pressure data can be obtained for each measured person based on the identification code, or can be compared with the previous measurement result, and the result can be displayed on the CRT. Display, store in external storage media, and automatically create patient charts.

In the portable automatic sphygmomanometer according to the second aspect, when the blood pressure measurement time set by the measurement time setting means is reached, an alarm device is activated based on a command from the measurement time setting means. A warning sound is emitted and the identification code of the subject person is displayed on the display means.

【Example】

<First Embodiment> An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view of a portable automatic sphygmomanometer according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a schematic configuration thereof. The portable automatic sphygmomanometer 1 according to the present embodiment is composed of a cuff 2 and a device body 3, both of which are connected by a detachable air pipe 4 and a microphone signal wiring 5, respectively. As shown in FIG. 2, the cuff 2 has an air bag 6 and a microphone 7 built-in, and is wrapped around the upper arm of the measurement subject.

On the front panel of the apparatus main body 3, a display 8 for displaying the measured blood pressure value, a function key group 9 for inputting / outputting data as described later and its processing, a patient identification code (ID code). ) And the like are provided on the ten-key pad 10, an operation key group 11 for giving an operation command, and the like. Reference numeral 12 in FIG. 1 is a band for carrying the apparatus body 3.

As shown in FIG. 2, an air pump 13 for supplying air to the cuff 2, a pressure sensor 14 for measuring the pressure in the cuff 2, and an air in the cuff 2 are exhausted in the apparatus body 3. A throttle valve 15 and an electromagnetic opening / closing valve 16 for controlling, a Korotkoff sound judging device 17 for judging the presence or absence of Korotkoff sound, a pressure sensor 14, and a CPU 18 for calculating a blood pressure value based on detection signals of the Korotkoff sound judging device 17, A memory 19 for storing the blood pressure data and the like, a data transfer unit 20 for transferring the contents of the memory 19 to the outside, an alarm device 21 for issuing an alarm sound, and a timer unit 2 for measuring the date and time of blood pressure measurement.
2. A battery 23 for supplying electric power to each part of the apparatus is provided.

The operation of the portable automatic blood pressure monitor according to this embodiment will be described below with reference to the flowchart of FIG. The feature of this embodiment is that the subject (patient) is measured before blood pressure measurement is started.
Is to input a unique ID code to the device. That is, the nurse presses the "f.1" key in the function key group 9 before measuring the blood pressure (step S
1). As a result, a character display prompting the input of the ID code is displayed on the display 8 (step S2). The nurse uses the ten-key pad 10 to input the ID code of the patient (step S3).

When the ID code is entered, the blood pressure of the patient is subsequently measured. When the nurse presses the "start" key in the operation key group 11 (step S4), the CPU 18 issues a drive command to the air pump 13. This allows air piping 4
Air is sent to the air bag 6 of the cuff 2 via the air bag 6, and the air bag 6 tightens the upper arm of the patient (step S5). The internal pressure of the air bladder 6 is constantly measured by the pressure sensor 14, and the CPU 18 monitors whether or not the internal pressure has reached a value set in advance so as to be higher than the systolic blood pressure value of the patient ( Step S6). When the internal pressure of the air bladder 6 reaches the set value, the CPU 18 issues a stop command to the air pump 13 and opens the electromagnetic opening / closing valve 16 (step S7). Since the throttle valve 15 is installed on the upstream side of the electromagnetic opening / closing valve 16, the internal pressure of the air bladder 6 starts to gradually decrease.

When the intracuff pressure drops to the maximum blood pressure value of the patient, Korotkoff sound is generated. This is detected by the microphone 7, and the Korotkoff sound determination device 17
The detection signal is sent to 8 (step S8). As a result, the CPU 18 reads the value of the pressure sensor 14 and sets the value as the systolic blood pressure value (step S9). The internal pressure of the air bladder 6 continues to decrease further, and when the internal pressure reaches the minimum blood pressure value,
Korotkoff sounds disappear. This is the Korotkoff sound judging device 1
7 makes a determination, and issues the detection signal to the CPU 18 (Stenop S10). The CPU 18 is the pressure sensor 1 at that time.
The value of 4 is set as the minimum blood pressure value (step S11).

When the blood pressure measurement is completed, the CPU 18 reads the blood pressure measurement date and time at that time from the clock unit 22 (step S12). Then, the blood pressure measurement date, the maximum blood pressure value, and the minimum blood pressure value are written in the memory 19 in association with the ID code of the patient (step S13).

After the blood pressure measurement of one patient is completed, the nurse inputs the ID code of a new patient and then shifts to the blood pressure measurement of the subject in the same manner as described above. In this way, the blood pressure values of a large number of patients and their measurement dates and times are recorded in the memory 19 in association with the ID code of each patient. Figure 4
It is the one schematically showing the blood pressure data recorded in the memory 19.

After completing the series of measurements, the nurse returns to the station and connects the device body 3 to the personal computer 30 as an external storage medium. Next, by pressing the “transfer” key in the operation key group 11, the contents of the memory 19 are read out and transferred to the personal computer 30 via the data transfer section 20, and the personal computer 3
It is recorded in 0, for example, on a hard disk or the like. When the data transfer is completed, the contents of the memory 19 are erased.

The personal computer 30 given the blood pressure data refers to the measurement time associated with the ID code of each patient and calculates the next (for example, 30 minutes later) blood pressure measurement time for each patient. , The data is attached to each ID code and transferred to the apparatus main body 3 in reverse. The data of the next measurement date and time of each patient is stored in the memory 19 in the apparatus body 3. FIG. 5 schematically shows the next measurement date and time data for each patient recorded in the memory 19.

When the reverse transfer of the next measurement date and time is completed,
The device body 3 is separated from the personal computer 30. Then, if necessary, the apparatus body 3 is connected to the charger 31 and the battery 23 in the apparatus body 3 is charged.

When the next measurement date / time data is stored in the memory 19, the CPU 18 of the apparatus main body 3 refers to the next measurement date / time data in the memory 19, and the date / time data from the timer 22 reaches the next measurement date / time data. Alarm 2
1 is activated to generate an alarm sound, and the ID code of the patient who has reached the measurement time is displayed on the display 8. By doing so, it is possible to prevent the nurse from forgetting the next blood pressure measurement.

The blood pressure data transferred to the personal computer 30 is displayed on the CRT by re-editing the blood pressure transition from the start of treatment of a specific patient by the nurse operating the keyboard of the personal computer 30 as necessary. It Further, this reedited data may be recorded again in the memory 19 of the apparatus main body 3. By doing this, the nurse presses the “read” key in the operation key group 11 of the device body 3 at the next blood pressure measurement,
The history of blood pressure data of a specific patient can be read from the memory 19 and displayed on the display unit 8 to check the blood pressure transition of the patient.

Since the portable automatic sphygmomanometer according to the present embodiment is always portable and has the function key group 9 and the numeric keypad 10, it has the following functions in addition to those described above. It is also possible to add.

Generally, when a decrease in blood pressure of a patient is recognized,
Although physiological saline may be infused into a patient, the main purpose of dialysis treatment is to remove water from the patient, and this injection amount is related to the total amount of water removed in dialysis. Therefore, the nurse notes this amount and re-lists it in the chart. However, according to the portable automatic sphygmomanometer according to the present embodiment, for example, if the “f · 2” key of the function key group 9 is made to function for the infusion volume, first the “f · 1” key is used to identify the patient ID. It is possible to store these data in the memory 19 by inputting a code, then pressing the “f · 2” key, and further inputting the infusion amount using the ten key 10. These data are stored in the device main body 3 in the personal computer 3
When connected to 0, it will be transferred with the blood pressure data and will be filled in the chart automatically.

Further, by effectively utilizing each function key group 9, various events occurring during dialysis treatment are recorded in the memory 19 by using the ten keys 10.
It is also possible to transfer the content to the personal computer 30.

The function of each function key group 9 may be fixed, or may be set from the personal computer 30 when the apparatus main body 3 is connected to the personal computer 30. Further, since the maximum blood pressure value is different for each patient, the maximum internal pressure applied to the cuff 2 may also be input and set from the personal computer 30.

Although the rechargeable battery 23 is used as the driving power source in the embodiment, a non-rechargeable dry battery may be used. Further, the sphygmomanometer is not limited to the Korotkoff sound method described in the present embodiment, and any electronic sphygmomanometer capable of being lightweight and compact, such as an oscillometric method or a finger cuff, may be used.

Further, the apparatus main body 3 may be provided with a wireless transmission function so as to appropriately communicate with the personal computer 30 or have a telephone function. However, it is inconvenient for the portable automatic blood pressure monitor according to the present invention to be too large because the nurse constantly hangs it on his neck, hangs it on his shoulder, or hooks it on his waist belt. Therefore, the size is preferably 60 mm in width × 40 in thickness.
mm × length 200 mm or less, and more preferably, the weight of the apparatus body 3 is set to 500 g or less.

Further, the input means of the ID code for identifying the patient is not limited to numeric input using the ten-key pad 10 as in the embodiment, but may be input with an alpha bed or a symbol. Further, it may be two input switches of “up” and “down” that simply increase or decrease the number.

Further, the method of inputting the ID code may be an automatic input means combining a known bar code and a bar code reader. That is, while sticking the bar code on the pillar of the patient's bed or on the patient himself,
The main body 3 of the portable automatic sphygmomanometer 1 is provided with the function of a barcode reader. Thus, the nurse can bring the barcode reader into contact with the barcode corresponding to the bed or the patient before the blood pressure measurement, and have the portable automatic blood pressure monitor 1 automatically identify the patient. Further, in this case, the barcode reader can be used as the data transfer unit 20. Because the barcode reader has the function of transmitting and receiving optical signals. Therefore, if the personal computer 30 is also provided with an optical data transfer unit (not shown), information can be exchanged by optical transmission between the two when they are connected. That is, by operating with a combination of a light emitting unit (hereinafter, referred to as A) and a light receiving unit (hereinafter, referred to as a) of the data transfer unit 20 of the portable automatic blood pressure monitor 1, it becomes a barcode reader for identifying a patient. Further, by combining A and the light receiving section of the data transfer section of the personal computer 30, the blood pressure information measured by the portable automatic blood pressure monitor 1 can be transferred to the personal computer 30. Further, the light emitting unit of the data transfer unit of the personal computer 30 and the a
If combined with each other, information such as the maximum applied cuff pressure of the patient stored in the personal computer 30 can be transferred to the portable automatic blood pressure monitor 1. As the configuration of the barcode reader,
The pen type that irradiates spot light and moves laterally on the barcode is better than the touch type that slit-shaped and makes contact with the entire barcode at once.

Further, in the above embodiment, the personal computer 30 judges the next measurement date and time of the patient and writes it in the memory 19 of the apparatus main body 3.
Since the blood pressure measurement interval is determined by the hospital, it can be stored in the memory 19 in advance or can be directly input to the CPU 18 using the ten-key pad 10. By doing so, when the first blood pressure measurement is completed, the subsequent measurement date and time will be CP.
It may be programmed so that U18 itself may make the determination.

Dialysis is started simultaneously under the operation of a nurse. In addition, since there is a change of nurses on the way, it is difficult to manage the net dialysis time for each patient who has 50 patients at the same time. As one embodiment of the present invention, when the nurse starts the dialysis treatment, the CPU 18 is informed of the start of the dialysis from a predetermined function key, and the CP
The U18 may grasp the accurate dialysis start time based on the output of the clock unit 22. After completing the dialysis start operation for all patients, the nurse may return to the filling station and transfer it to the personal computer 30 to display the dialysis end time for each patient on the CRT of the personal computer 30. Moreover, since the dialysis time is generally fixed by the facility / patient, the personal computer 30
It is also possible to display the remaining dialysis time on the display 8 of the apparatus main body 3 by the judgment of the CPU 18 without depending on the above.

It should be noted that if the processing is performed inside the personal computer and the patient who needs the work next or the patient who finishes dialysis is displayed on the CRT in order, or whether the blood pressure transition of the patient is appropriate is determined automatically. , Can be useful for nurses' work plans.

Furthermore, the ID code for patient identification does not necessarily have to be directly connected to each patient, as long as it can be distinguished from other patients treated at the same time. Therefore, when a large number of patients are targeted, it may be more convenient to use a room or bed number. Usually, the patient's bed and treatment date are fixed, so I
Even if the D code is defined, this does not confuse the patient. If these are changed, the personal computer 30 may be provided with a correspondence list, and this list may be updated appropriately.

Further, in the above embodiment, the portable automatic blood pressure monitor suitable for dialysis treatment was explained, but the present invention is not limited to this, and in various cases where it is necessary to measure the blood pressure of many subjects. Can be applied to.

<Second Embodiment> A second embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG. 6 is an external perspective view of the portable automatic sphygmomanometer according to the present embodiment, and FIG. 7 is a block diagram showing a schematic configuration of the embodiment apparatus. 6 and 7
In FIG. 2, the portions denoted by the same reference numerals as those in FIGS. 1 and 2 have the same configuration as that of the first embodiment, and therefore the description thereof is omitted here.

The present embodiment is different from the first embodiment in the following points. (1) Although the electrically driven air pump 13 is used as the air pump in the first embodiment, the rubber ball manual pump 101 is used in place of this in the second embodiment. (2) Instead of the exhaust throttle valve 15 and the electromagnetic opening / closing valve 16, a manually adjusted exhaust valve 102 is provided. (3) The blood pressure determination method is an oscillometric method instead of the Korotkoff sound method. (4) The maximum cuff internal pressure setting device 103 is provided, and the buzzer sound is emitted from the alarm device 21 when the cuff internal pressure reaches this value.

The configuration of the present embodiment will be specifically described below. In this embodiment, the pressure raising and depressurizing operations in the cuff are performed by the rubber ball manual pump 101 and the exhaust valve 102. As the rubber ball manual pump 101, for example, a known pump described in JP-B-61-2562 is used. In measuring the blood pressure, the nurse wears the cuff 2 on the upper arm of the patient and inputs the ID code of the patient, as in the first embodiment. Thereafter, the maximum applied cuff internal pressure is set by the maximum cuff internal pressure setting device 103. Normally, the maximum applied cuff pressure is set to a value higher than the expected maximum blood pressure of the patient by several tens of mmHg. The maximum cuff pressure setting device 103 is high / medium /
The maximum cuff pressure is set by selecting low. For example, "high" is 220mmHg and "medium" is 180mm.
mmHg, "Low" is set to 150 mmHg.

Next, the nurse grips the rubber ball manual pump 101 on the palm and crushes it about 10 times to repeat the operation, thereby sending air to the cuff 2 and raising the pressure of the air bag 6. The pressure in the cuff during this period is constantly detected by the pressure sensor 14, and the direct current component (which is a smoothed pulse wave described later) in the detection signal is taken out by the low pass filter 141 and given to the CPU 18.
When the DC component value reaches the value set by the maximum cuff internal pressure setting device 103, the CPU 18 instructs the alarm device 21 to generate a buzzer sound. As a result, the nurse stops the pressurizing operation of the rubber ball manual pump 101. Then the exhaust valve 102
When is operated to open, the internal pressure of the cuff 2 starts to gradually decrease.

When the cuff pressure drops to the systolic blood pressure of the patient, the oscillating arterial waves of blood vessels are superimposed on the applied cuff pressure. This pulse wave signal is taken out by the bandpass filter 142 and CP
Give to U18. Due to the generation of this pulse wave signal, the CPU 18
Determines that the maximum blood pressure point has been reached, and the DC component at this time is taken out via the low-pass filter 141 to obtain the maximum blood pressure value. When the intracuff pressure further decreases and reaches the minimum blood pressure value, the pulse wave disappears. CPU18
Determines the disappearance of the pulse wave based on the output signal of the bandpass filter 142, and sets the DC component from the lowpass filter 141 at this time as the minimum blood pressure value. The maximum and minimum blood pressure values measured as described above are written in the memory 19 in association with the ID code of the patient as in the first embodiment, and displayed on the display 9. The blood pressure data of each patient recorded in the memory 19 is transferred to the personal computer 30 via the data transfer unit 20 as in the first embodiment.

In this embodiment, the pressure increase of the cuff 2 depends on the nurse. However, when the internal pressure of the cuff reaches the set maximum internal pressure of the cuff, the buzzer sounds to inform the nurse. Until it rings, the rubber ball manual pump 101 can be operated while performing another operation such as hearing the patient's condition. In this respect, compared with the conventional method in which the pressure is increased while reading the value of the mercury column etc., the nerve burden on the nurse is very small. Further, the buzzer can be used to prevent the internal pressure of the cuff from becoming an excessively applied pressure, so that the device is not damaged and the patient is not overloaded.

Further, as compared with the first embodiment using the electric pump, there are the following advantages. (1) Since the number of parts is small, the manufacturing cost of the sphygmomanometer can be reduced. (2) In the first embodiment, not only the electric pump but also the battery for driving the electric pump is indispensable. Although this battery has a large volume, it has a considerable weight, which also causes an increase in the total weight of the portable automatic blood pressure monitor. On the other hand, in the present embodiment, not only the electric pump is unnecessary, but also the battery is sufficient as the mercury battery, so that the portable automatic blood pressure monitor can be made compact and lightweight. This is an important factor in the dialysis treatment in which a nurse goes around regularly. In the apparatus of this embodiment, the size is about the so-called electronic notebook, and the weight can be 200 g or less. Therefore, the carrying method can be inserted into the pocket or worn on the waist belt, so that it is possible to eliminate the uncomfortable feeling of carrying at all times. (3) In the first embodiment, since a too large electric pump cannot be used, the boosting speed is somewhat slower, but in this embodiment, rapid boosting is possible without increasing the burden on the nurse. Thus, the blood pressure measurement time can be shortened. This is a great advantage for both nurses and patients.

Although the maximum cuff pressure is set by the maximum cuff pressure setting device 103 in this embodiment, the maximum cuff pressure is stored in advance in the memory 19 in association with the patient's ID code, and the blood pressure is stored. The maximum cuff pressure data of the patient may be read from the memory 19 and set based on the patient ID code input by the nurse at the time of measurement. Alternatively, in the process of increasing the pressure of the cuff 2, the generation / disappearance of a pulse wave may be determined, and the maximum internal pressure of the cuff may be automatically set based on that. Also, the cuff internal pressure is, for example, 1
One alarm sound when reaching 50mmHg, 180mm
The cuff pressure may be notified to the nurse by ringing twice when Hg is reached and three times when 200 mmHg is reached.

Further, the exhaust valve 102 is not limited to a manual type, but for example, a mechanical exhaust valve with an automatic pressure reducing function as described in Japanese Utility Model Publication No. 61-2562, or Japanese Patent Publication No.
You may use the electric type pressure change speed adjusting device etc. which were described in 20247 gazette.

Further, as the air pump, a rubber ball manual pump and an electric pump may be used together. By doing so, the following advantages are obtained. (1) The pressurization time of the cuff 2 can be further shortened. (2) When the pressure of the cuff 2 starts to be increased, a rubber ball manual pump and an electric pump are used, and after the internal pressure of the cuff has risen to a certain degree, only the electric pump is used to increase the pressure so that the final pressure applied to the cuff can be accurately measured. Can be adjusted. As a result, the internal pressure of the cuff does not rise more than necessary, and the burden on the patient can be reduced. (3) If another task (for example, measurement of body temperature) occurs during blood pressure measurement, automatic measurement is performed only by the electric pump after wearing the cuff, and the nurse can perform other tasks during this period. ..

The device of the first embodiment or the device of the second embodiment described above may be provided with a pager function.
In this case, when the patient presses the nurse call button, the wireless signal is received by the portable automatic sphygmomanometer of the above-mentioned embodiment, the alarm device 21 is activated, and the bed number of the patient is displayed on the display device 8 in characters.

In both of the embodiments, the blood pressure measurement site is not limited to the upper arm and may be the wrist, for example. In this case, in a normal patient, even if there is a large difference in the thickness of the upper arm portion, the difference in the thickness of the wrist portion is small and the cuff is easily attached because it is exposed. Therefore, if the cuff structure is made into a half-cylindrical shape, the cuff can be easily attached / detached with one touch.

[0051]

As is apparent from the above description, according to the portable automatic sphygmomanometer according to claim 1, the blood pressure value of each subject and the measurement date and time are unique to each subject. It is configured to be stored in the main body of the device in association with the identification code and transferred to an external storage medium if necessary, so that the nurse can record the blood pressure value and measurement date and time of each subject on a recording sheet each time. It is possible to save the trouble of having to write it down, and also to eliminate the error caused by writing. Further, according to the portable automatic blood pressure monitor of the present invention, since the nurse can always carry it,
This is convenient when the blood pressures of a large number of measurement subjects are sequentially measured, and is cheaper than when a blood pressure monitor is installed for each measurement subject.

Further, according to the portable automatic sphygmomanometer of the second aspect, in addition to the above configuration, the measurement time setting means for presetting the blood pressure measurement time of each subject and the measurement time setting means Equipped with an alarm that operates according to
When the set measurement time is reached, an alarm sound is issued based on a command from the measurement time setting means, and the identification code of the target person to be measured is displayed on the display means. It is possible to avoid the situation of forgetting to take the measurement, and it is possible to reduce the burden that the nurse keeps the blood pressure measurement time in memory.
