1 Introduction With the improvement of people's living standards, people pay more and more attention to their physical health. They are eager to find a simple and portable diagnostic and therapeutic instrument that can be easily inspected and diagnosed according to their needs at any time and any place. In order to understand your physical condition as early as possible, and to provide timely and auxiliary treatment for general diseases. Inspired by the theory of acupuncture and moxibustion of traditional Chinese medicine, according to the knowledge of electronic technology and the theory of Chinese medicine, a portable body "health diagnosis and treatment" circuit is designed, and a simple "health diagnosis and treatment instrument" is made according to the circuit principle. The diagnosis and treatment instrument uses a probe to detect the relevant acupoints in the body, and judges whether there is a disease in an organ of the body through the "stinging" feeling of the relevant acupoint, and can perform auxiliary treatment under the "treatment" state. This article refers to the address: http:// The circuit is mainly composed of two parts: a timing circuit composed of a timer 555 and its peripheral circuits, and a high frequency oscillation circuit composed of R0 to R2, C1 to C4, VQ1 and a high frequency transformer T. The working principle of the timing circuit is relatively simple and will not be described in detail here. The following is a brief introduction to the high frequency oscillation circuit.

2 The theory is based on the cellular activity of the muscles, nerves, tissues and organs of the human body, which produces a weak electrical phenomenon. It is formed by the change of a living electron in the living organism. The movement of bioelectronics produces a creature unique to the living body. Electricity. In the whole life of the human body, the movement of bio-electronics is inseparable. It always maintains a relative balance in the imbalance, and these bio-electricity generated by the physiological processes of various cells, tissues, organs and systems in the human body. Due to the interaction between each other and the conductivity of the body, an electric axis projection is formed on the body surface according to the skin effect or the principle of the volume conductor conduction, forming a series of equivalent lines and special resistance points of the antenna without a unique anatomical structure. That is, acupoints. As early as the 1960s, medical scientists at home and abroad have proved through experiments that these equivalent lines and special points of resistance have low electrical resistance with respect to the surrounding skin. Later, experiments have proved that the skin is conductive when the internal organs and the body are damaged. The amount is generally increased, especially in the extreme "positive" reaction at the corresponding acupoints, that is, the conductivity is significantly increased. The point of high conductivity on the skin is called the “good guide pointâ€, and the imaginary line that is connected with the good guide point is called “good guideâ€. Therefore, by measuring “good guide point†and “good guide†A change in the electrical resistance value can diagnose the presence or absence of a disease in the relevant pulmonary sputum, which has an important role in the early prevention and treatment of the disease.
3 circuit principle and component selection
3.1 Circuit principle According to the characteristics of the acupoints of the human body is lower than the surrounding skin. The high-frequency oscillating circuit is supplemented with some peripheral circuits, and two small probes are added to contact with the human body to form a "disease diagnosis and treatment" circuit. The most basic part of the circuit is a batch oscillator whose oscillation frequency is controlled by the resistance between the "fixed probe" and the "hole probe", as shown in Figure 1. 
When switch K1 is closed and K2 is placed in position 2, the circuit is in a diagnostic state. The power supply first charges the capacitors C1 and C3 respectively. When the anode potential of C1 and C3 reaches the corresponding potential, VQ1 is turned on; at this time, C2 is charged, and C1 starts to discharge. When C2 is charged to a certain potential, VQ1 is turned off, C2 and C3 are discharged through the high-frequency transformer T, and the power supply charges the capacitors C1 and C3 again, and VQ1 is turned on again. Due to the charge and discharge of C2 and C3, a high-frequency current is coupled to the secondary side of the high-frequency transformer, and the human body flows through the two probes through C4 and R0. When the two probes are in contact with the non-acupoint skin of the human body, the probe asks for a large resistance value, and the current flowing through is small, and the human body has no "stinging" feeling. When the probe is combined with the acupoint, the electrical resistance between the "fixed probe" and the "cavity probe" is significantly reduced, and the oscillating current flowing through the human body is significantly increased. The lower the resistance of the "fixed probe" and the "hole probe", the higher the oscillation frequency, the larger the oscillating current, and the stronger the tingling feeling. According to the strength of the tingling sensation and the position of the acupoints, it is judged whether there is a lesion in the corresponding organs of the body.
During treatment, switch K2 is placed in position 1, the probe contacts the corresponding acupoint, and the high-frequency current is explored to flow to the human body. Repeat the stimulation of the corresponding acupoints to achieve therapeutic goals. As seen from the schematic diagram, at this time, the timer 555 operates, and its action determines the time of stimulating the acupuncture points. Every time the time is up, it is a “treatmentâ€.
3.2 Component selection and debugging The diagnosis and treatment circuit of this disease is not complicated, but component selection and debugging is a rather cumbersome process. How to make the circuit start to vibrate at the acupuncture point of the human body? How to create a needle-like feeling at the acupuncture points? It is the key to eliminating misdiagnosis. After repeated experiments, the author finally determined the most suitable parameters for each component in the circuit. In order to adapt to different people and different external environment changes (such as ambient temperature, humidity, different people's sensitivity to pain, etc.), an adjustable resistor is specially configured in the circuit to adjust the circuit current. VQ1 selects 9013, and can also use 3DG6, 3DGl2A and other low-power high-frequency triodes. All other triodes use 9014, or 3AX21, 3AX31. The transformer uses the output transformer of V309 type or other types of transistor radio. The smaller the size of the speaker, the better. Generally, a permanent magnet type speaker with a diameter of 20 to 30 mm or a buzzer can be used directly. A copper tube with a diameter of about 10 to 15 mm and a length of 10 mm is used as a "fixed probe". Use a multi-meter-sized metal pen holder as a “cavity probeâ€. Note that there is an insulating sleeve outside the “cavity probe†for the diagnostician to hold. There are no special requirements for resistors and capacitors, as long as their nominal values ​​correspond to the calibration values ​​in the figure.
4 How to use When using, first adjust the test treatment current. Relatively fixed to a probe, pinched on the hand or specially made a soft "ear plug" probe cover, put it on the back and stuff it in the ear, then put another probe on the "Shaoyang hole" (specific Refer to the relevant Chinese medicine acupoint map for position and adjust the adjustable potentiometer in the circuit to increase the current until the tester has a noticeable tingling sensation. At this point, the test treatment current has been adjusted. Then, slide the probe at the "Shaoyang Point" on the other parts of the body surface. When it comes into contact with the acupuncture points, the high-frequency oscillating circuit starts to oscillate due to the low resistance, and the speaker emits “howlingâ€. If the internal organs have lesions, the conductivity at the corresponding acupoints will increase greatly, and the high-frequency oscillating circuit will flow through. "Big" current, at this time, not only the speaker sound becomes sharp, but also the needle-like "stinging" feeling at the acupuncture point and the ear where the "large" current is felt, which is a positive point. According to the acupoint distribution map (see Table 1), it can be known which organ of the body is in poor health. 
5 Conclusions Verification by multiple experiments. The human disease auxiliary diagnosis and treatment electronic instrument not only has a wide detection range, but also has a wide range of colds, and can detect pancreatic lesions, and the accuracy rate is up to 90%. It is a very effective and feasible health detecting device, and at the same time, the device is suitable for diseases. The treatment also has certain auxiliary effects, and it is believed that it will be widely used in the near future.
