BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patient monitoring device, and more particularly to a patient monitoring device which can be reliably operated remotely by separating a light receiving portion.

[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. Conventionally, as shown in FIG. 3, a remotely operable patient monitoring device has been used to improve the efficiency of patient monitoring. In the figure, reference numeral 20 is a main body of the patient monitoring apparatus, and 10 is a remote control unit configured separately from the main body 20. For example, when monitoring an electrocardiographic signal of a patient, the operation switch 10 that constitutes the switch unit 102 of the remote operation unit 10 described above.
If you press the corresponding one of 2A, 102B ...
An optical switch signal 1 is emitted from the remote control unit 1 to the space. The optical switch signal 1 is supplied to the light receiving section 203 of the main body 20.
, And the electrocardiogram signal derived from the living body of the patient corresponding to the optical switch signal 1 is input to the main body 20. The electrocardiogram signal input to the main body 20 is subjected to predetermined processing, and then necessary information such as an electrocardiogram waveform and a heart rate is displayed on the display unit 202.
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. When simultaneously displaying information on two or more biological signals such as an electrocardiogram signal, a pulse wave signal, and an electroencephalogram signal, the corresponding operation switches of the remote operation unit 10 are simultaneously pressed. The patient monitoring apparatus of FIG. 3 can be operated in a place away from the main body 20 and does not need to bother to approach the main body 20. Therefore, it is extremely effective in diagnosing a large number of patients in a hospital or during surgery. ..

[0003]

However, it is usual that not only the patient monitoring device but also other medical equipment or OA equipment such as a computer is installed in the hospital room, and these are not always required. It is not arranged in any order. In particular, in an operating room, many other devices may be placed near the main body 20 in order to perform a quick and reliable operation. In that case, for example, as shown in FIG.
3 is hidden, and the optical switch signal 1 emitted from the remote control unit 10 does not reach the light receiving unit 203. Therefore, the operation of the main body 20 by the remote operation unit 10 becomes impossible. as a result,
It is not possible to take prompt measures depending on the condition of the patient, and the efficiency of patient monitoring decreases. An object of the present invention is to separate the light-receiving part so that the patient monitoring device can be reliably operated remotely without being disturbed by other devices, and the patient can be quickly treated according to the condition of the patient. It is to improve the monitoring efficiency.

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.

Since the biological signal input from the computer has a high transmission speed and cannot be processed by the CPU 2A6 in that state, the RAM 2
This is because the data is once stored in A7 and is processed by the CPU 2A6 without omission. The CPU 2A6 inputs the biological signal T3 stored in the RAM 2A7, analyzes it based on an instruction from the remote control unit 1, outputs an information signal T4 relating to the biological signal to be displayed on the display unit 2A1, and the main body 2 This device controls the overall control.

Operate.

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, holding the case 11 of the remote control unit 1 in the hand, of the switches 1A111, 1A12, etc. constituting the switch unit 1A1, a switch necessary for inputting an electrocardiogram signal to the main body 2 is pushed. 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, and C
Input to PU1A2. The CPU 1A2 inputs the switch signal S1, recognizes which switch is pressed, and outputs a corresponding recognition signal S2. The recognition signal S2 is
The modulated signal S3 is input to the modulator 1A3 and modulated by a carrier having a predetermined frequency, and the modulated signal S3 is output to the light emitting unit 1A4. In the light emitting unit 1A4, as described above,
When the modulation signal S3 turns on and off the bipolar PNP transistor which is a driving element of the infrared light emitting diode, a current intermittently flows from the current source of the light emitting diode, whereby the infrared optical switch signal L is emitted. The radiated optical switch signal L is input to the light receiving unit 4 installed on the ceiling, converted into an electric signal by the photodiode, and the modulated signal S8 of the electric signal is output. This modulated signal S8 is sent to the demodulation unit 2A14 via the cable 5.
Is input to the switch controller 2A12 and demodulated, and the same recognition signal S9 as the original predetermined recognition signal S2 is output.
To enter. In the switch controller 2A12, the serial recognition signal S9 is converted into a parallel recognition signal S4, which is input to the CPU 2A6. 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. As a result, the input box 3 causes the CPU 2 to output only the electrocardiogram signal T1 out of the biological signals collected from the living body of the patient.
Send to A6. Specifically, the electrocardiogram signal T
1 is serial communication 2 as described above.
After parallel conversion via A8 and once stored in RAM2A7, it is input to the CPU2A6 by an instruction signal S10 from the CPU2A6. The CPU 2A6 uses the recognition signal S
4 based on 4, the electrocardiogram signal T input from the RAM2A7
3 is analyzed and the information displayed on the display unit 2A1, for example, the waveform of the electrocardiogram signal, the heart rate, etc., is output as the information signal T4. This information signal T4 is used by the graphic controller 2
It is input to A4 and converted into a video signal, and the converted video signal T5 is displayed by the display controller 2A2 on the display unit 2A1.
The necessary processing for displaying on the
6 is input to the display unit 2A1. As a result, the display unit 2
Information on the electrocardiogram signal T1 input from the input box 3 is displayed on A1.
