On the other hand, in the case of the sod pulse generator, a lot of clinical data is automatically displayed after diagnosis by adding pulse information to the computer software.

The pulser can analyze the touch, texture, vein and the like through the pulse of the unit time, and can discriminate the constitution.

However, the conventional pulsator has a limitation in that it can not provide more detailed and diverse self-diagnostic information such as physiological signals and vital symptoms to the user because the pulse wave is measured based only on the pulse wave.

Configuration for the interface unit 108 as a sensing pad portion 100, and;

A PC system (109) for receiving and processing the sensed information through the interface means (108);

And it was configured to be in close contact with each sensor accurately.

FIG. 3 is a plan view showing the position of each sensor in the palm-shaped intaglio portion 204 of the pad 202 and which part of the palm is in close contact with each other. EKG sensors 101a are respectively provided at the center of the palm, and skin resistance sensors 102a are respectively provided at the lower side of the middle finger and the lower side of the palm, and pulse sensors 103a are respectively provided at the upper part of the blade and the upper part of the index finger. It has shown that the temperature sensor 104a was provided in the lowermost part and the blade lower part, respectively.

Hereinafter, with reference to the accompanying drawings will be described the operation of the present invention.

First, as shown in Figs. 2 and 3, the sensing pad unit 100 and the PC system 109 are connected using the RS-232C port 203 as the interface means 108.

Then, the user places the palm on the palm-shaped intaglio 204 and lightly presses the palm so as to be in close contact with various sensors 101a, 102a, 103a and 104a.

On the other hand, in this state, the PC system 109 drives the mounted diagnostic program and asks whether or not the diagnostic is to be executed on the monitor screen, and in response to this, the user inputs the diagnostic execution using a mouse or a keyboard.

When the diagnosis is executed, all the information detected by the sensing means of FIG. 1 are processed and transmitted to the PC system.

First, the electrocardiogram detecting means 101 detects the electrocardiogram with the electrocardiogram sensor 101a and supplies an electric signal (waveform) corresponding to the electrocardiogram to the amplifying means 105.

Electrocardiogram (ECG) is a record based on the electrical activity of the heart.The steady-state potential of normal cells has a negative charge in the cells and a positive charge in the extracellular cells. This information is derived from the aspect of electrical conduction.

These electrocardiograms are represented by the electrical activity of cardiomyocytes, the electrical region of the heart, the potential of the body surface, and the electrodes. Therefore, when the electrocardiogram associated with the heartbeat is observed, heart-related information that cannot be observed by the pulse can be obtained.

In the present invention, the ECG uses only the ECG sensor 101a located in the right hand (or the left hand). Therefore, the right hand can only locally measure the right atrium and the right ventricle and the left hand at the left atrium and the left ventricle. This can be enough information for a simple medical examination device compared to.

As described above, the electrocardiogram detecting means 101 converts the detected electrocardiogram information into an electrical signal and inputs a predetermined electrocardiogram detection signal (waveform) to the amplifying means 105.

On the other hand, the skin resistance detecting means 102 detects the skin resistance by the skin resistance sensor 102a and inputs the detected skin resistance to the amplifying means 105 as a predetermined signal.

Galvanic Skin Response (GSR) is related to stress.

In other words, human mental adjustment or relaxation process may be the cause of increase and decrease in skin resistance. Therefore, high and low skin resistance correlate with relaxation and stress, respectively. It is in a relaxed state, whereas low skin resistance is considered to be an awake state.

In general, skin resistance is defined as a sense level (tense level) below 5kΩ, and relaxation level (calm level) when skin resistance is above 25kΩ, so the mental health state can be indirectly determined by measuring skin resistance. .

For example, low levels of cortical stimulation are prominent in relaxation, hypnosis, and emotional unconsciousness, and high levels of cortical stimulation are present in situations such as strong reactions, concentration, and rushing movements.

Cortical stimulation here has a simple relationship with skin conductivity. Cortical stimulation of the brain increases the conductivity of the skin. Conversely, the lower the cortical stimulation, the lower the conductivity of the skin.

Therefore, measuring and analyzing skin resistance can indirectly determine mental health.

On the other hand, the pulse sensor 103a detects a small microcer pulse.

The pulse detected by the pulse sensor 103a is converted into an electrical signal corresponding to the pulse by the pulse detecting means 103 and input to the amplifying means 105.

Since the pulse is the heart rate per unit time, observing this pulse can determine whether the heart rate is normal.

Then, the body temperature detecting means 104 converts the body temperature of the user detected by the body temperature sensor 104a into an electrical signal and inputs it to the amplifying means 105.

There is no room for explanation that body temperature is used as a basis for health status.

The amplifying means 105 amplifies the ECG detection signal, the skin resistance detection signal, the pulse detection signal, and the body temperature detection signal detected as described above to a predetermined level sufficient for digital signal processing at a later stage.

The amplifying means 105 is composed of a differential amplifier to achieve a stable high-gain amplification.

The sensed signal thus amplified is input to the analog digital conversion means 106 and converted into a digital signal. In the present invention, digital conversion is performed at a sampling rate of 8 bits / s.

The digital signal processing means 107 performs the filtering of the input digital signal (detection signal) using the filter unit 107a, and processes the sensing signal (processing by a PC) using the signal processing unit 107b. Processing in the signal format of.

Digital signal filtering not only removes noise, but also extracts only the signal components of the frequency band of the waveform where the ECG is observed, and extracts only the signal components of the frequency band of the waveform where the pulse is observed. Has the effect of filtering.

In addition, the filtering removes a frequency component of 60 Hz corresponding to the electrical signal, and makes it possible to detect a physiological signal (˜200 Hz) within the voice signal frequency band (20 Hz to 2 kHz).

Further, the digital signal processing means 107 samples the four sensed signals with a predetermined sampling period and multiplexes them.

The ECG, skin resistance, pulse, and temperature sensing information finally processed by the digital signal processing means 107 is transmitted to the PC system 109 via the interface means 108.

The PC system 109 compares the input electrocardiogram, skin resistance, pulse, and temperature sensing information with a previously constructed database, and determines whether it is healthy, and displays the diagnosis result on the monitor screen.

That is, a database for making a diagnosis is constructed in the storage unit 110 of the PC system 109. In the first memory unit 110a, electrocardiogram, skin resistance, pulse, and temperature data, which are the standards of the same generation, are stored. In the second memory unit 110b, the average value of the measured value in units of one week (and / or 30 days) is stored, and in the third memory unit 110c, the average value of the last three measured values before the current measurement point is stored. .

The sensing information processing unit 111 of the PC system 109 compares the digital signal input via the interface means 108, that is, the electrocardiogram, skin resistance, pulse, and body temperature information with the database stored in the storage unit 110. And the deviation is calculated.

That is, the deviation between the measured value of the same generation and the present measured value stored in the first memory unit 110a, and the measured value in units of one week (and / or 30 days) stored in the second memory unit 110b. The difference between the average value and the present measured value, the deviation between the average value of the last three days and the present measured value stored in the third storage unit 110c are calculated.

On the basis of the deviation information calculated as above, the diagnosis unit 112 diagnoses whether it is normal, and informs the user of the diagnosis result as appropriate character and / or graphic information on the monitor screen through the display unit 113. .

4 shows an example of such a monitor display screen.

That is, on the diagnosis screen 401 of a suitable design, a window window 402 for displaying the current measured pulse and body temperature and skin resistance value, a window 403 for displaying the evaluation result in text, and calculation from the measured result. A window 404 for displaying a health index in a weekly unit and a window 405 for displaying a graph in a 30 day unit are shown.

Of course, the form of such a screen display is only one example, and may be implemented in a more diverse and detailed display form of information.

5A and 5B show a case of using a mouse pad as an embodiment of the sensing pad 202 in the present invention.

One side 501 of the flat type mouse pad was planarized so that the mouse 503 could be used. A palm-shaped engraved part 502 was formed on the back of the flat mouse pad. The sensors are positioned in place, and the pad board 201 as shown in FIG. 2 is built in the mouse pad, so that the mouse pad can be used as the medical diagnostic pad of the present invention.

That is, in case of using as a mouse pad, a mouse may be used as shown in FIG. 5A. When the user wants a simple medical examination, the user may face the palm of the intaglio part 502 with the palm upside as shown in FIG. 5B.
