The display unit 2A1 is a device that displays information regarding the biological signal T1 input via the input box 3, and can be formed of, for example, a liquid crystal display, as described above. The input box 3 is a device that collects biomedical signals derived from a living body of a patient and transmits the biomedical signals to the main body 2. If the main body 2 is brought close to the patient, it will be an obstacle in the case of surgery, etc. Therefore, the main body 2 is arranged at a place far from the patient, and the input box 3 is placed between them, and the necessary biosignal Input only to the main body 2. More specifically, as will be described later, the input box 3 is, depending on which switch 1A11, 1A12 ... Of the switch unit 1A1 of the remote control unit 1 is pressed,
A necessary one T1 of the collected biomedical signals is transmitted to the main body 2. For example, when there is an abnormality in the blood pressure of the patient, the input box 3 sends a pulse wave signal representing a change in blood pressure to the main body 2 among the biological signals derived from the living body of the patient according to an instruction from the remote control unit 1. .. The serial communication 2A8 is a device that converts the serial biological signal T1 transmitted from the input box 3 and outputs a parallel biological signal T2. This is because the RAM 2A7 at the next stage reads the biological signal quickly. The RAM 2A7 is a device for inputting and temporarily storing the biological signal T2 input from the serial communication 2A8. This is because the biological signal input from the input box 3 has a high transmission speed and cannot be processed by the CPU 2A6 if it is left as it is, so that the biological signal is once stored in the RAM 2A7 and is processed by the CPU 2A6 without being read. CPU2A6 above

The light receiving unit 2A10 is a device that receives the optical switch signal L, which is a modulation signal transmitted from the remote control unit 1, photoelectrically changes it, and outputs a modulation signal S8 that is converted into an electric signal. The demodulation unit 2A14 is
This is a device that inputs the modulation signal S8, demodulates it, and outputs the same recognition signal S9 as the recognition signal S2. The serial communication 2A12 is a device that converts the serial recognition signal S9 and outputs a parallel recognition signal S4. The sound generator 2A13 has an instruction signal S from the CPU 2A6 when an alarm occurs.
It is a device that inputs 7 and outputs an alarm signal S6.
The speaker 2A11 inputs the alarm signal S6,
It is a device that outputs a buzzer sound to notify the occurrence of an alarm. The serial communication 2A12
Operates not only by the signal S9 corresponding to the signal from the switch unit 1A1 constituting the remote control unit 1, but also by the signal S5 from the switch unit 2A9 constituting the main body 2.

The operation of the present invention having the above configuration will be described below. For example, when a patient has a heart disease, information regarding the electrocardiogram signal of the patient is displayed on the display unit 2A1 of the main body 2.
Take the example when you want to display in. First, the case 11 of the remote control unit 1 is held in the hand, and one of the switches 1A11, 1A12, etc. constituting the switch unit 1A1 is pressed to input the electrocardiogram signal LS to the main body 2. As a result, a predetermined switch signal S1 is output from the switch unit 1A1 that constitutes the circuit 1A of the remote control unit 1,
Input to CPU1A2. The CPU 1A2 inputs the switch signal S1 to recognize which switch is pressed,
The corresponding recognition signal S2 is output. The recognition signal S2
Is input to the modulator 1A3 and modulated by a carrier wave having a predetermined frequency, and a modulated signal S3 is output and input to the light emitting unit 1A4. In the light emitting section 1A4, as described above, the modulation signal S3 turns on and off the bipolar PNP transistor which is a driving element of the infrared light emitting diode, so that the current intermittently flows from the current source of the light emitting diode. As a result, the infrared optical switch signal L is emitted. The emitted optical switch signal L is input to the light receiving portion 2A10 of the main body 2 and photoelectrically converted, and is constituted by a bipolar PNP transistor (not shown) which is an element,
By turning on / off the bipolar PNP transistor by the modulation signal S3, the light emitting diode is driven, and thereby the infrared optical switch signal L is emitted. The emitted optical switch signal L is input to the light receiving portion 2A10 of the main body 2 and converted into an electric signal, and the modulated signal S8 of the electric signal is output. This modulated signal S3 is input to the demodulation section 2A14 and demodulated, and the original predetermined recognition signal S
The same recognition signal S9 as 2 is output and input to the serial communication 2A12. In the serial communication 2A12, the serial recognition signal S9 is used.
Is converted to output a parallel recognition signal S4, and C
Input to PU2A6. Based on the input recognition signal S4, the CPU 2A6 recognizes which switch of the switch unit 1A1 forming the remote control unit 1 has been pressed, and in this case determines that it is necessary to input an electrocardiogram signal from the input box 3. .. Therefore, the CPU 2A6 sends the instruction signal S11 to the input box 3 so as to input the electrocardiogram signal. This allows input box 3
Transmits only the electrocardiogram signal T1 from the biological signals collected from the patient's biological body to the CPU 2A6. Specifically, as described above, the electrocardiogram signal T1 is parallel-converted through the serial communication 2A8, temporarily stored in the RAM 2A7, and then input to the CPU 2A6 by the instruction signal S10 from the CPU 2A6. CPU
The 2A6 analyzes the electrocardiogram signal T3 input from the RAM 2A7 based on the recognition signal S4, and outputs the information displayed on the display unit 2A1, for example, the waveform of the electrocardiogram signal and the heart rate as the information signal T4. This information signal T4 is input to the graphic controller 2A4 and converted into a video signal, and the converted video signal T5 is the display controller 2A2.
Then, necessary processing for displaying on the display unit 2A1 is performed, and the processed signal T6 is input to the display unit 2A1. As a result, the display unit 2A1 displays the information regarding the electrocardiogram signal T1 input from the input box 3.
