Description

[Detailed description of the invention] Background of the invention (1) Technical field The present invention relates to an electronic blood pressure monitor having automatic pressurization and depressurization functions.

(2) Prior art and its problems Conventionally, in this type of electronic blood pressure monitor, measurement was started only after the power switch was first turned on and the measurement start switch was turned on second. Therefore, two operations are required for the purpose of measurement, which is troublesome. In addition, after the power was turned on, the start switch could not be turned on unless a certain period of time was waited for the zero adjustment of the pressure converter to be completed.

Purpose of the invention The present invention was created in view of the above-mentioned conventional technology, and it realizes operations related to blood pressure measurement with a single operation, and also compares the current measurement results with the average results measured in the past. However, the aim is to provide an electronic blood pressure monitor that can be used to monitor blood pressure.

Configuration of the Invention In order to achieve the above object, the electronic blood pressure monitor of the present invention has the following configuration. That is, a display means for displaying information, an information holding means for storing and storing a plurality of measured blood pressure values, a means for placing a peripheral device related to blood pressure measurement in a standby state in a normal state, and a means for instructing the start of blood pressure measurement. an instruction means; and a control means for executing a series of blood pressure measurements when the instruction means receives an instruction to start blood pressure measurement; storage means for storing in the memory holding means; average value calculation means for calculating the average of the blood pressure values held in the information storage holding means; and average value calculation means for calculating the average blood pressure value calculated by the current blood pressure value and the average value calculation means. Display instruction means for causing the display means to display the information.

Further, if the electronic blood pressure monitor is a blood pressure monitor that operates with a built-in battery, the electronic blood pressure monitor is provided with a detection means for detecting the degree of battery consumption, and the control means receives an instruction to start blood pressure measurement by the instruction means. It is desirable to execute a series of blood pressure measurement processes only when the detection means determines that the power supply capacity of the battery is equal to or higher than a predetermined value.

Furthermore, it is preferable that the control means displays the time in the normal standby state and instructs the device to display the temperature at which the device was placed at the measurement start time before the blood pressure value is determined.

Detailed Description and Effects of the Invention Hereinafter, one embodiment of the invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of the electronic blood pressure monitor of this embodiment.

In the figure, 1 is a CPU that controls each peripheral device related to the electronic blood pressure monitor. Reference numeral 2 denotes a ROM in which a program of a flowchart showing a series of processes shown in FIG. 2, which will be described later, is stored. 3 is a RAM used to store measurement results and as a work area for programs. 4 is a sound collecting microphone, and 5 is a Korotkoff sound detection device for detecting Korotkoff sounds from the sound collecting microphone 4. 6 is an outside temperature measuring device that measures the outside air temperature, 7 is a pressure increase value setting device that sets the value to pressurize the cuff in advance, and 8 measures the pressure inside the cuff and converts the magnitude of the pressure into an electrical quantity. It is a pressure transducer that converts Reference numeral 9 denotes an A/D that converts the electric quantity outputted from the above-mentioned Korotkoff sound detection device 5, outside air temperature measurement device 6, pressure increase value setting device 7, pressure converter 8, etc. into a digital quantity and sends the code to the CPU 1. It is a converter. Reference numeral 10 denotes a start switch provided to start measurement with this blood pressure monitor. Reference numeral 11 denotes a battery consumption level detection device for detecting the consumption level of a battery that serves as a power source within the blood pressure monitor. Also 12
13 is a pressurizing pump that pumps air into the cuff to increase the pressure, and 13 is a pump that exhausts the air in the cuff at a constant speed when measuring the systolic or diastolic blood pressure. It is a constant speed exhaust system. Further, numeral 16 is a rapid exhaust device that exhausts the remaining blood after the blood pressure measurement is completed. Reference numeral 14 denotes an alarm buzzer that notifies the outside when measurement is started or when an abnormal value or the like is measured. Reference numeral 15 is a clock to which power is constantly supplied, and reference numeral 17 is a liquid crystal display that displays measurement results and time. Although both the measurement result and time may be displayed at the same time, it is preferable to display either one of them in order to downsize the liquid crystal display and to make it easier to read the measurement result and time. As a preferable method, it is preferable to display the time in the normal state and switch to display the measurement results after blood pressure measurement has started.

The operation will be explained below according to the flowchart shown in FIG.

At step S1, CPU1 switches to start switch 10.
is “ON” or not, and when it is “OFF”, for example, CPU1 is in a stopped state (halt state),
The peripheral devices are in a standby state, and their power consumption is low. In addition, the start switch 10
When is "ON", this signal becomes an interrupt signal for the CPU 1, and the process moves to step S2. Step S
In Step 2, it is determined based on the signal from the battery consumption level detection device 11 whether the battery that will serve as a power source in the following measurements has enough power to supply the necessary power. What this means is that the pump used to measure blood pressure consumes a large amount of power, and when the pump is driven, the voltage drops below the operating voltage of CPU 1 and other circuits, making it impossible for the device to perform its original processing. This is to prevent it from running out. Therefore, when it is detected that the battery is depleted to a certain extent, a message to that effect is displayed on the liquid crystal display 17, and in step S4, each input key etc. is locked, prompting the user to replace the battery. If it is determined in step S2 that the battery has sufficient power supply capacity to perform the series of operations described below, the process proceeds to step S5. First, in step S5, the LCD display 17
, a predetermined message is displayed, and the process moves to step S6, where an alarm buzzer is sounded to notify the start of blood pressure measurement. In step S7, the pressure transducer 8 is zero-corrected as an initial stage of measurement. Next, in step S8, the data from the outside air temperature measuring device 6 is converted into an A/D converter to measure the outside air temperature.
The temperature is input via the converter 9 and displayed on the liquid crystal display 17 in step S9. In step S10, the boost value setting device 7
Read the boost value inputted from step S11.
The pressurizing pump 12 for boosting the pressure is driven to the boost value read in, and air is sent to the arm or the like. Step S12
The constant speed exhaust device 13 is driven to gradually exhaust the air in the cuff that has been pressurized to the pressure increase value to lower the pressure.
The signal from the Korotkoff sound detection device is passed through the A/D converter 9, and the systolic blood pressure value is measured in step S13. Further, after measuring the systolic blood pressure value, step S14 is performed until the diastolic blood pressure value is measured.
Measure your pulse rate. During this time, the pressure within the cuff gradually decreases, and the diastolic blood pressure value is measured in step S15. After all measurements of the systolic blood pressure value, diastolic blood pressure value, and pulse rate are completed, the rapid exhaust device 16 is driven in step S16 to exhaust the air remaining in the cuff, and each measured value is measured in step S17.
Store it in RAM3. Next, in step S18, the average value of the measured values up to the previous time is calculated, including the current measurement value, and in step S19, the current maximum and diastolic blood pressure values, pulse rate, and the measured values up to the previous time are calculated. The average maximum and diastolic blood pressure values and average pulse rate are displayed on the liquid crystal display 17, and the series of measurements is completed.

As described above, according to this embodiment, the operation for executing the process related to blood pressure measurement can be performed with a single operation, and the systolic and diastolic blood pressure values and pulse rate obtained by measurement can be obtained using previously measured data. Since you will be able to compare it with the average of , you will be able to accurately understand your current physical condition. Furthermore, according to the above embodiment, when the start of blood pressure measurement is instructed, the battery consumption level is checked first, and only when it is determined that there is no problem in performing a series of blood pressure measurements,
Blood pressure measurement is being performed. Therefore, it is ensured that the obtained measurement results are not measured under unstable conditions due to battery exhaustion, but at least under normal conditions, which increases confidence in the obtained data. The quality is high.

Effects of the invention As explained above, according to the invention, operations related to blood pressure measurement can be realized with a single operation, and the current measurement results can be compared with the average results measured in the past. It becomes like this.
