Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patient monitoring apparatus, and more particularly to a patient monitoring apparatus for displaying biometric information on a display section separated from a main body and connecting a video signal display apparatus to the main body.

[0002]

2. Description of the Related Art Generally, a patient monitoring device is a device for constantly monitoring the condition of a patient by inputting a biological signal such as an electrocardiogram signal of the patient and performing a predetermined process. The conventional patient monitoring apparatus has the configuration shown in FIG. In the figure, reference numeral 20 is a main body of a patient monitoring apparatus, 201
Is its display unit, and 20A, 20B ... Are operation switches. For example, when monitoring an electrocardiogram signal of a patient, by pressing the corresponding one of the operation switches 20A, 20B ..., The electrocardiogram signal derived from the living body of the patient is input to the main body 20. The electrocardiogram signal input to the main body 20 is subjected to predetermined processing, and then the electrocardiogram waveform,
Necessary information such as the heart rate is displayed on the display unit 201. In addition to the electrocardiogram signal, the same operation is performed on other biological signals such as a pulse wave signal and an electroencephalogram signal. To simultaneously display information on two or more biological signals such as an electrocardiogram signal, a pulse wave signal, and an electroencephalogram signal, press the corresponding operation switch.

[0003]

As described above, in the prior art (FIG. 5), the information about the biomedical signal is displayed on the display unit 21 formed integrally with the main body 20. Therefore, there are the following problems. (1) The entire patient monitoring device becomes large and requires a large occupied space when used. That is, since various devices are arranged in the hospital, it is desirable to make the patient monitoring device as small as possible and to occupy the space occupied by the device. In particular, in an operating room, quick and reliable actions are required, and therefore, if the patient monitoring device is large, the occupied space becomes large accordingly and the action range is limited. Further, even if the display unit is made thin by using a liquid crystal display, if the main body and the display unit are integrally formed, the whole patient monitoring device becomes large, and it is meaningless to make the display unit thin. I will end up. (2) The display unit cannot be freely selected, and effective patient monitoring according to the situation cannot be performed. For example, in an operating room, a nurse's room, etc., a so-called large slave monitor that is hung from the ceiling is used in addition to the patient monitoring device.
In this case, the display unit integrated with the main body is not always necessary, and a main body for controlling display is sufficient. But,
Conventionally, as shown in FIG. 5, since the display unit 201 is integrated with the main body 20, an interface is required between the main unit 20 and the slave monitor when the slave monitor is used. I can't choose. (3) A video signal display device such as a television receiver cannot be connected. In order to solve the above problems (1) and (2), an invention has been proposed in which the display unit is separated from the main body. In this case, if a plurality of display units are provided, the efficiency of patient monitoring is further improved.
However, the display unit is generally expensive, and it is not appropriate to prepare many units. It would be realistic if the biometric information could be displayed by connecting a video signal display device such as a television receiver to the main body instead of the display unit, and the rest of the display unit. No ingenuity has been made. Therefore, the efficiency of patient monitoring decreases. An object of the present invention is to separate the display unit from the main body so that the space occupied by the patient monitoring device can be reduced, the display unit can be freely selected, and the video signal display device can be connected to the main body. Especially.

[0004]

Means for Solving the Problems The above-mentioned problem is solved by the input means for inputting a biological signal T1 derived from a living body of a subject, and the information signal T4 by subjecting the input biological signal T1 to a predetermined process in accordance with an instruction from the outside. And a control section for outputting the information signal T4 and an output means for converting the information signal T4 to output a video signal T5, and a main body 2 to which a video signal display device 6 can be connected. An input unit for inputting a biological signal T1 from a living body of a subject and a subject, a control unit for performing a predetermined process on the input biological signal T1 according to an instruction from the outside, and outputting an information signal T4; An output means for converting the signal T4 and outputting a video signal T5, and the video signal display device 6 is provided to the output means.
And a display unit 5 that is configured separately from the main unit 2 and that is connectable to the main unit 2 and that displays the predetermined biometric information on its display means by inputting the video signal T5. It is solved by the monitoring device.

[0005]

As described above, according to the present invention, as shown in FIG. 1, the input means for inputting the biological signal T1 derived from the living body of the subject and the input biological signal T1 are predetermined by external instructions. And the output means for converting the information signal T4 and outputting the video signal T5, and the video signal display device 6 can be connected to the output means. Patient monitoring device and a bio-signal T1 from the living body of the subject.
An input means for inputting the input signal, a control unit for performing a predetermined process on the input biological signal T1 according to an instruction from the outside to output an information signal T4, and an output for converting the information signal T4 and outputting a video signal T5. 2 and a main body 2 having means for connecting the video signal display device 6 to the output means.
There is provided a patient monitoring apparatus, which is configured separately from and which comprises a display unit 5 for inputting the video signal T5 and displaying predetermined biological information on its display means. According to the above configuration, the main body 2 that performs a predetermined process on the biomedical signal derived from the living body of the patient and the display unit 5 that displays information related to the biomedical signal are separately and independently configured. Therefore, as compared with the conventional patient monitoring apparatus in which the main body and the display unit are integrated (FIG. 5), if the display unit 5 is formed of liquid crystal, for example, the entire apparatus becomes smaller. Moreover, since the main body 2 and the display unit 5 are separately configured, an interface is not required even when a slave monitor is connected, for example. Therefore, the display unit can be freely selected. Further, since the video signal display device 6 can be connected to the main body 2, the patient monitoring work can be performed by displaying biometric information on the video signal display device 6 together with the display unit 5. That is, according to the present invention,
By separating the display unit from the main body, the space occupied by the patient monitoring apparatus can be reduced, the display unit can be freely selected, and the video signal display device can be connected to the main body.
