In conventional Chinese medicine, to diagnose the condition of a per-testee, the pathology is diagnosed by a sense or a touch obtained by palpation (finger screening) at the area of the examinee's radial artery, duct, and chuck. However, this method has a problem that the reliability of the diagnosis is lowered due to incorrect diagnosis results due to the difference in the sense of the examinee and the difference in career.

In order to solve this problem, an electronic pulsation recording device (Patent Publication 76-78) in which a piezoelectric element is installed in three parts of a village, a pipe, and a chuck to inspect a pulse wave has been invented and used. The pulse wave signal obtained by the device is amplified by driving the galvanometer to record the pulse wave in the speaker or display tube (display tube) to check the health condition of the examinee to solve the above problems to some extent, but it is an analog recording method. Therefore, the electrical characteristics, time, and amplitude of the pulse wave cannot be calculated and analyzed easily, and the means for measuring the pulse rate per breath are not provided. Therefore, the pulse rate per breath cannot be accurately measured. have.

One minute pulse rate and the like can be analyzed precisely, the analyzed pulse wave data can be stored in the secondary memory device HDD (hard disk drive), and the data can be taken out and displayed on the screen for comparison. In this case, the pulse wave can be calibrated, reduced / enlarged, moved, stopped, and the like, and thus, the correlated waveform can be analyzed more precisely, thereby providing an advanced pulse recording device capable of accurate diagnosis.

When described in detail with reference to the drawings as follows.

First, referring to FIG. 1, which shows a block diagram of the computerized pulse recording apparatus of the present invention, the present invention relates to a pulse and a detection ceramic band for detecting pulse waves at three regions of the wrist, duct, and chuck on the radial artery of the wrist. 7), preamplifiers (OP ₁ -OP ₃ ), filters (f ₁ -f ₃ ), amplifiers (OP ₄ -OP ₆ ), which receive electrical analog pulse wave signals from the pulse wave detection band (7), A three-channel A / D conversion interface circuit 5 composed of an A / D converter 14-16 and a buffer 12, a decoder 13, and the like, and the signal strength of the signal connected to the A / D conversion interface circuit. Is connected to the buffer 12, the display selection switch unit 10 connected to the buffer 12 to select a pulse wave display mode, and the buffer 12 to pulse the breathing signal of the examinee. A breathing conductor 9 for sending a form, a digital electromagnetic pressurizing device 8 for connecting the bulge and sending a pulse wave detection start signal, and the A / D conversion interface A personal computer (PC) 2 connected to the switch circuit 5 and performing various commands to the peripheral device; a monitor 1, a printer 4, an HDD 6, which are peripheral devices of the personal computer 2; It consists of the keyboard 3.

Referring to the effect of the present invention configured as described above are as follows.

First, when the command to start the operation by the CPU of the personal computer 2 drops, the pulse wave detector (T ₁ -T ₃ ) installed on the wrist electrically connects the pulse wave of the hill, tube, and chuck 3 sites through three channels. The detected analog signal is applied to the preamplifiers OP _1- OP ₃ of the three-channel A / D conversion interface circuit 5, and the signals are amplified by the preamplifiers OP _1- OP ₃ , and then the filter f _1- f ₃ ) After passing only the low-frequency pulse wave band, the voltage is amplified by the amplifiers (OP ₄ -OP ₆ ), and the LED level display unit 11 displays the signal strength and three A / D converters 14. -16) to convert an analog signal into a digital signal. This signal is loaded onto the data bus of the personal computer 2 via the buffer 12 and processed by the CPU.

At this time, the physical computer 2 converts the digital signal into an analog signal again to display the analog pulse wave signal on the monitor, and sends the digital signal to the printer so that the pulse wave, characters and numerical values are recorded in the printer.

In the display of the pulse wave on the monitor 1, when the pulse wave is to be continuously displayed (see FIGS. 3A and 3B), the switch SW1 of the display selection switch unit 10 is shown as the C axis in FIG. When the H (high) potential is applied to the terminal B side of the buffer 12, the buffer 12 notifies the CPU of this and the pulse wave continuously detected on the monitor 1 is detected by the appropriate program of the CPU, and the pulse wave is subjected to three steps. In other words, when the display is to be displayed in negative, medium, or needle (see also 3c), the switch SW1 is set to the P side of the buffer 12, and L is displayed on the terminal C side of the buffer. When the (low) potential is applied, a signal is applied to the CPU through the buffer 12, and pulse waves separated into the monitor 1 are detected by the appropriate program of the CPU in three stages. Is displayed on the monitor 12, the digital electromagnetic pressurization device 8 generates a pulse wave detection start signal, Here the starting point is the time to which the L (low) signal to the A pulse wave is a program be drawn to the right in the left monitor.

The reason for detecting the pulse wave by separating the pulse wave in successive or three steps is that the analysis of the pulse wave can be made more diversified. In other words, if the pulse wave is continuously displayed, the pulse wave can be observed at a glance from the needle state to the negative state, so that the flow of the pulse, arrhythmias, and changes in amplitude can be seen. In this case, by automatically displaying the needle, middle, and negative pulse waves on the screen by the program, it is possible to eliminate the inconvenience of detecting the pulse waves by manually manipulating the pressure change manually as in the conventional art.

In FIG. 3, S denotes when the pulse wave is at the reference point, P denotes when it is at the highest point, D denotes when it is at the lowest point, and SP denotes the time until the wave reaches the highest point at the reference point. Period, SP represents the amplitude from the reference point to the highest point, and PD represents the amplitude from the highest point to the lowest point of the pulse wave.

In the integrated circuit, which is a heavy buffer 12 circuit, a second pin is used to connect to the digital electronic pressure device 8, the respirator 9, and the display selection switch 10 to obtain a new effect by using extra pins. The detailed diagram in the case of using the integrated circuit 74LS244 as the buffer 12 is shown.

As shown in FIG. 2, the buffer 12 receives a digital signal from the A / D converter 14-16 and applies a signal to the CPU through the data bus D ₀ -D ₇ and also from the CPU. Receives the signal through the decoder, and also the pulse wave detection start signal from the digital voltage device (8) through the A pin, the breath signal from the respiratory conductor (9) and the display selection switch unit (10) through the B pin. Receives the traffic light from the controller and applies it to the CPU through the data bus frame so that the CPU can perform the proper operation.
