Description

Portable Magnetic Acupuncture Machine

The utility model belongs to a small medical device.

Acupuncture therapy is one of the ancient and effective medical methods in our country. With the development of electromagnetic theory and biological theory, people have developed magnetic therapy, such as fixing magnetic rings made of permanent magnets on acupuncture points for magnetic therapy, etc. , and achieved a certain medical effect.

The purpose of the utility model is to provide a portable magnetic needle therapy machine.

The utility model is composed of a reciprocating magnetic therapy needle, a drive mechanism for the reciprocating motion of the magnetic therapy needle, a control device and a casing. The front end of the magnetic therapy needle is provided with a permanent magnet with a magnetic field strength of 600-8000 gauss.

In order to determine the treatment time, a timer or a multi-way timer can also be set in the utility model for determining the treatment time for single or multiple patients.

The magnetic therapy needle of the utility model performs reciprocating motion at a certain frequency under the driving and control of the driving mechanism and the control device. During treatment, acupoints can be selected according to the patient's treatment needs, and then the needles of the magnetic therapy needles can be aligned with the acupoints. In this way, the magnetic therapy needle hits the selected acupuncture point with a certain frequency, because the magnetic field strength of the magnetic therapy needle is between 600-8000 gauss. Therefore, when the needle head of the magnetic therapy needle approaches or leaves the acupuncture point, a strong magnetic beam penetrates into or leaves the acupuncture point, which is equivalent to the acupuncture effect of a strong invisible magnetic needle, and when the needle head of the magnetic therapy needle hits When reaching the acupoints, in addition to the magnetic effect on the acupoints, it also has a pressing effect on the acupoints, which is equivalent to the function of the 鍉 needle in the ancient "nine needles". All diseases that can be treated by conventional acupuncture can be treated by the utility model. It is painless and has outstanding curative effect on diseases such as diabetes.

Now in conjunction with accompanying drawing, the utility model is further described. The portable magnetic acupuncture machine shown in Fig. 1 is made up of a magnetic therapy needle, a driving mechanism, a control device 6, a casing 11, and a lead wire 7 and a plug 8. The magnetic therapy needle is composed of a needle head 1, a connecting rod 2 and a back cap 3. The needle head 1 is made of permanent magnet, the magnetic field strength is between 600-8000 gauss, the needle head 1 is arranged on the front end of the connecting rod 2, the back cap 3 is made of steel material, and is fixed on the rear end of the connecting rod 2 with threads. The driving mechanism is composed of a spring 4 and an electromagnet 5, and the spring 4 is arranged between the back cap 3 and the electromagnet 5. One end of the spring 4 close to the electromagnet 5 is fixed on the casing 11 . A limit stopper 10 is arranged on the shell 11, and a limit stopper 9 is arranged on the magnetic therapy needle. Through the limit stoppers 9 and 10, the stroke of the magnetic therapy needle is limited. The circuit structure of the control device 6 is shown in FIG. 4 . The magnetic therapy needle, the driving mechanism, and the control device are all arranged in the housing 11, and their installation positions are shown in FIG. 1 .

The circuit structure of the control device 6 is composed of a self-excited multivibrator circuit, a control circuit, a drive circuit and two sets of DC working power supplies.

The self-excited multivibrator circuit is composed of resistor R ₂ , regulator tube W ₁ , resistor R ₃ , capacitor C ₃ , diode D ₅ and 555 integrated circuits. When the power is turned on, because the capacitor _C3 has no time to charge, the pin ② of the 555 integrated circuit is at a low level, resulting in a high level output. When the power supply charges capacitor C3 through resistor R ₁ , voltage regulator tube W ₁ and resistor R ₃ until VC≥ 2/3 VCC, the output changes from high level to low level, making the discharge tube inside _the 555 integrated circuit When it is turned on, the capacitor C ₃ is discharged through the regulator tube W ₁ , the resistor R ₃ and the discharge tube. When the level drops to VC≤ 1/3 VCC, the output changes from low level to high level. Capacitor C ₃ is charged again, so it goes round and round to form an oscillation. Diode D ₅ is the charging guide tube. When adjusting the voltage regulator tube W ₁ , the output terminal ③ of the 555 integrated circuit can be output, and the duty factor DF is in the range of 2 to 98%. internally changing square wave. Therefore, the power-on time of the control circuit can also vary within a wide range of 2-98%.

The period and frequency of the oscillation are approximately:

T = (R ₂ +W ₁ +R ₃ )·C ₃ /1.46

f=1/T

The duty cycle _is : DF = (R ₂ + W)/(R ₂ + W ₁ + R ₃ )

where W is the value of W _above the contact part of ₁ .

The control circuit is composed of 555 integrated circuit, resistor R ₅ and triode T ₁ . When the square liquid with adjustable duty ratio generated by the self-excited multivibrator circuit is output through the ③ pin of the 555 integrated circuit, when the square liquid output by the 555 integrated circuit is at a high potential, the base potential Vb of the triode _T1 increases, making The transistor _T1 is turned on, so that the driving circuit load _RL and the resistor _R4 controlled by the transistor _T1 are turned on. When the square wave output by the 555 integrated circuit is at a low potential, the base potential Vb of the triode _T1 drops, and the triode _T1 is cut off. This cycle makes the driving circuit and the control circuit act simultaneously.

The driving circuit is composed of load _RL , resistor _R4 and diode _D6 . When the control circuit outputs a high level and the base potential Vb of the transistor _T1 is greater than 0, the transistor _T1 is turned on, and the rectified DC voltage passes through the load _RL , the current limiting resistor _R4 and the collector of the transistor _T1 It forms a path with the emitter, and the load _RL acts. When the control circuit outputs a low level, that is, when Vb is less than 0, the transistor _T1 is cut off. At this time, the load _RL circuit is cut off because there is no current passing through it.

Because _RL is an inductive element, there is inductance in this way. When the transistor _T1 is cut off, a very high induced electromotive force will be generated on _RL , and this induced electromotive force will be added to the transistor _T1 together with the power supply voltage, which may damage the transistor _T1 , so in order to protect the transistor _T1 , in R _L Diode D ₆ is connected in parallel, when the triode T ₁ is turned off, the induced electromotive force forms a path and discharges, so that the current change rate becomes smaller, and the induced electromotive force is also reduced, which plays a role in protecting the triode T ₁ .

In order to make the whole machine work better, the DC power supply adopts a transformerless rectifier circuit. When the AC source is connected, the AC power is stepped down by the capacitor _C1 , and the bridge rectification of the diodes _D1 - _D4 is used as the total DC working power supply. The unfiltered and stabilized DC voltage is limited by resistor _R1 , stabilized by _DW1 and filtered by capacitor _C2 , and then supplied to the self-excited multivibrator circuit composed of 555 integrated circuits and the working power of the control circuit.

The other path is supplied to the working power of the driving circuit after being stabilized and filtered by the regulator tube DW ₂ and the capacitor C ₄ .

When in use _, turn on _the switch K _{1 ,} the 220 _- volt AC power supply is _supplied to _the self- _excited oscillation circuit and The drive circuit is used as a power supply. At the moment when the power is turned on, the capacitor C ₃ has no time to charge, so that the ② pin of the 555 integrated circuit is at a low level, and the output terminal ③ is at a high level. After the T time, the capacitor C ₃ is charged to a value greater than 2/ When VCC is 3, that is, pin ② of the 555 integrated circuit is at high level, so that pin ③ of the output terminal is at low level, and oscillation is formed repeatedly. This oscillating signal is controlled by R ₅ and triode T ₁ of the control circuit, so that the driving circuit _RL and R ₄ operate cyclically according to the level of the oscillating signal output by the control circuit. That is to say, the coil of the electromagnet 5 of the driving mechanism has current to pass through, or there is no current to pass through. When the coil of the electromagnet 5 has current to pass through, the armature of the electromagnet will attract the back cap 3, and drive the whole magnetic therapy needle to move backward. , at this time the spring 4 is in a compressed state. When the coil of the electromagnet 5 has no current passing through, the electromagnet 5 releases the back cap 3, and at this moment, the spring 4 bounces the magnetic therapy needle forward, and knocks the acupuncture point selected by the patient to achieve the purpose of treatment.

Fig. 2 and Fig. 3 are the structural representations of another embodiment of the present utility model. Its characteristic is that the control device is arranged in the control box 12, and the timer 13 and the buzzer 14 are also arranged in the control box 12.
