Description

Electronic Body Cavity Massager

The present invention relates to an electronic physiotherapy device, in particular to a device that inserts bipolar electrodes into the body cavity of a human body, stimulates the muscles, blood vessels, lymph and nerves of the human body by stimulating electric signals of a certain power, It directly acts on the mucous membrane of the body cavity, which can prevent muscle atrophy, reduce inflammation and relieve pain, and promote blood circulation and remove blood stasis. It can also be used for sampling body fluids such as rectal fluid.

The electronic massage apparatus that uses at present generally has body surface (skin) and body cavity (mucosa) and two kinds of electrode contacts. Massage instruments with electrodes in contact with the body surface have many disadvantages: due to the large dry resistance of the body surface and the insulating effect of the subcutaneous lipid layer, the instrument must use a large current and high voltage, sometimes even The 220V AC power supply becomes 9V power supply through the regulated power supply, which acts on the human body. There is a potential danger of breakdown current. Patients also have a strong needling sensation. Since this kind of instrument cannot overcome the pain caused by the acupuncture sensation, it cannot apply a stronger signal to the lesion, so the therapeutic effect is relatively poor. Especially for those important nerves hidden deep in the pelvis, such as the sciatic nerve and inferior gluteal nerve, because they have no corresponding movement points on the body surface, they cannot be stimulated at all. And most regular physical therapy departments have the disadvantages of being large in size and unable to be portable with the massaging instrument. The biggest shortcoming of massage instruments acting on the body surface is that the stimulation points on the body surface (such as acupoints in traditional Chinese medicine) are very scattered, and it takes time and effort to massage.

Most of the electronic massage instruments whose electrodes are in contact with the mucous membrane of the body cavity are unipolar single electrodes, bipolar single electrodes and unipolar double electrodes. It is usually used in conjunction with drugs. Monopolar single electrode is mostly used for microwave heating therapy. Unipolar double electrodes are mostly used for iontophoresis of drugs. Bipolar single electrodes are mostly used in sexual devices. The existing CN1070347A electronic gymnastics rehabilitation device is a bipolar bipolar medical instrument. It places the bipolars side by side in the vagina at the same time to rehabilitate the muscles. But it has the following disadvantages: ① Its electrodes are conductive rubber, which is not easy to be sterilized by high temperature; ② Its electrodes are only inserted into the vagina, and hard traction is performed. sports. Therefore, the patient feels uncomfortable and inconvenient to use; ③Because the two electrodes are placed in the vagina at the same time, only a general two-way pulse circuit can only be used to enhance the contraction ability of vaginal muscles, so the scope of treatment is too large. Small and bulky.

The object of the present invention is to design an electronic device that is small in size, can apply a strong signal to the lesion, directly cooperate with the electrode in the body cavity or the body surface electrode, and can treat various diseases by contacting the inner cavity mucous membrane and skin. massager.

The present invention is realized in the following way: it is an electronic medical device composed of a bipolar double electrode in a body cavity, an external bipolar single electrode and an oscillating circuit. It is divided into desktop and portable in form. The desktop includes: the instrument box and the bipolar double electrode in the body cavity and the bipolar single electrode outside the body. The instrument box includes a resonant signal generator circuit without a transformer, an asymmetric bidirectional pulse generator circuit with a transformer, and a power supply. And the bipolar bipolar electrode of oscillating circuit (it does not have transformer) circuit and electrode lead wire, traction line, switch, 6V DC power supply are formed in the built-in portable massage instrument. Among them, the resonance signal generator is supplied from the power supply to the oscillating circuit T1 to generate an AC signal, which is output to the primary voltage doubler circuit, so that the doubled voltage is added to the oscillating circuit T2, and then the secondary voltage is doubled; this voltage is added to T3 The pulse generator is applied to the electrode through C9. The asymmetric bidirectional pulse signal generator is applied to the blocking oscillation circuit T4 from the power supply, and the voltage is applied to the transformer boost circuit, and finally applied to the electrode. The electrode has a bipolar double electrode in the body cavity, which is composed of an upper hemispherical electrode and a lower hemispherical electrode part, as well as a wire and a traction wire. The middle insulating part is made of nylon or non-toxic plastic; the bipolar single electrode in vitro is made of medical conductive Composed of rubber and wires and plugs.

The present invention uses a resonant circuit, whose frequency is the same as the natural frequency of the human body, which can resonate muscles and prevent muscle atrophy. Stimulate to produce soreness, swelling, heaviness, and numbness, and achieve the massage effect of anti-inflammatory, pain-relieving, blood-activating and stasis-removing. If the electrode in the body cavity cooperates with the bipolar single electrode on the body surface, it can treat diseases of the prostate and spine. When the bipolar bipolar electrode in the body cavity is used under the bidirectional pulse circuit, it can be used for living body sampling such as rectal fluid.

As shown in Figures 1.1 and 1.2, this is a resonance generator circuit. The power supply is added to the oscillator circuit T1 (using 555) to generate an AC signal output. It is composed of R1 (5 ~ 18K, currently using 10K), C2 (10 ~ 30μF, Now use 20μF) to determine the frequency of the oscillating signal. This signal passes through a voltage doubler circuit composed of diodes D1, D2, C3 (20μF), and C4 (2500PF). This voltage generates another oscillation through T2 (556), and its oscillation frequency determines R2 (1～20K, 10K is currently used), C5 (2500PF), and then through the secondary voltage doubler circuit composed of D3, D4, C6 (10μF) and C7 (10μF), the output voltage is twice higher than the former , and then added to the T3 (556) pulse oscillation stage, its frequency is determined by R3 (5.1 ~ 30K, currently using 20K), R4 (610 ~ 1K, currently using 820Ω) and C8 (6.8μF). The duty cycle of the pulse whose frequency is less than 10HZ is determined by C10 (0.01μF); C9 (10μF) is the output coupling capacitor, which is then added to the electrode. It can be seen from the above that the resonance signal is driven by the low-frequency signal generated by the resistance-capacitance oscillation circuit, and the output current is less than 70mA.

As shown in Figures 1.3 and 1.4, this is an asymmetrical bidirectional pulse signal generating circuit. The capacitor C11 (22μF) is charged by the power supply to make T4 (9013) conduction. Because the terminals a and a' of the transformer with the same name increase the current, Make T4 saturated to form a steep pulse. After T4 is saturated, the pulse generates a flat top part, and because the current of the transformer increases, the base current decreases, so that the collector current also decreases, and T4 is cut off, thereby forming a steep falling edge. . As shown in Figure 1.5, this is the waveform of a pulse above 200V generated by the asymmetric bidirectional pulse generator after T4 is saturated. The cut-off of T4 will generate a counter electromotive force in the transformer B, so it will generate several times more than E2 in Figure 1.3. Kickback voltage, as shown in Figure 1.6, the waveform of the pulse generated by the asymmetric bidirectional pulse generator after T4 is cut off is above 300V. This is a blocking oscillation circuit. Then, the circuit enters the next cycle, and each cycle generates a Asymmetric bi-directional pulse signal. R5(100～300Ω, 200Ω for current use), R6(510Ω～5.1K, 2K for current use), R7(100～510Ω, 300Ω for current use), W1(20～100K, 50K for current use), W2(1～10K , currently using 3K), C11 (10 ~ 36μF, currently using 22μF), C12 (0.1 ~ 0.2μ, currently using 0.1μF). It can be seen from the above that this circuit generates high-frequency signals under the resistance-capacitance circuit, and the special modulation pulse required for T4 signal generation is raised to a voltage above 200V by the output of the triode and the transformer. The output current is less than 70mA.

As shown in Figure 2, this is a bipolar double electrode. The electrode is generally a rigid body electrode. The upper and lower ends of the cylindrical electrode are stainless steel hemispheres, and the material is 1Cr18Ni9Ti. Above △6, there are two holes on the upper end, one is the pulling wire installation hole (1), and the other is the wire lead-out hole (2). The middle part of the electrode is made of nylon or non-toxic plastic as a circular tube-shaped insulator (4) , (3) is the electrode on the upper hemisphere, (5) is the electrode on the lower hemisphere of the cylindrical electrode, if you use a desktop body cavity massager, there is an electrode groove (15) in the middle of the lower hemisphere (5), when the electrode is pulled out of the body cavity , can be stimulated by the impulse to produce body fluids, such as rectal fluid, which can be used for laboratory tests to diagnose rectal cancer. The bipolar bipolar electrode of the portable body cavity massager has a built-in resonance signal generator circuit, which is connected with an external power supply and a switch by a wire. It is only used in the body cavity for the treatment of preventing muscle atrophy. It can be seen that this kind of soft traction should not move and control the direction under the operation of the hands. The diameter of the electrode in the body cavity is 1-4 cm, and the length is 3-15 cm.

As shown in Figure 3, it is a body surface electrode. This is a bipolar single electrode, and the electrode is a general medical conductive rubber electrode, which is connected with a bidirectional pulse generator circuit by a wire. Its role in medical treatment is for the treatment of diseases such as spine and prostate (in conjunction with electrodes in body cavities).

As shown in Figure 4, it is the panel of the desktop instrument box. The box is composed of a resonance signal generator circuit, a bidirectional pulse generator circuit and a power supply. There are resonance signal generator circuit switch (7), indicator light (6), electrode socket (9), resonance signal generator intensity adjustment knob (8), two-way pulse signal generator switch (12), indicator light ( 13), the external electrode socket (10), the electrode socket (14) in the body cavity, and the intensity adjustment knob (11) of the asymmetric bidirectional pulse generator. The present invention uses direct current power supply, forms 6V direct current power supply with 4 sections of 5# batteries, also can use alternating current power supply, has power jack in the instrument.

When the power is turned on during use, on the desktop panel, the indicator light (6) of the resonance signal generator displays a red signal, indicating that the instrument is working normally. Adjust the intensity knob (8), and it is the best when the patient produces tolerable muscle resonance strength. When the indicator light (13) of the asymmetrical bidirectional pulse signal generator shows a green signal, it means that it is working normally. When the intensity adjustment knob (11) makes the patient feel soreness, swelling, heaviness, numbness and can be tolerated, it is the best intensity. .

The present invention utilizes the natural frequency of the human body, applies corresponding circuits to generate resonance, and makes the muscles, blood vessels, lymph, and nerves of the waist, abdomen, and lower limbs of the human body generate passive movements at the same time, so as to prevent muscle atrophy, promote blood circulation, remove blood stasis, and relieve pain. Purpose. When the present invention uses an asymmetrical bidirectional pulse circuit, the electrodes in the body cavity (including the anus, vagina, etc.) can cooperate with the body surface electrodes to treat spine and prostate diseases. (both electrodes can use the same signal source), (10 and 14 in Fig. 4 are the same signal source). Therefore, bi-directional pulses can act either in the body cavity alone or between the body cavity and the body surface. When the electrode in the body cavity is used in conjunction with the asymmetric bidirectional pulse circuit, it can also be used for sampling the living body of the rectal fluid in the body cavity, so as to achieve the purpose of diagnosing rectal cancer. The bipolar double electrodes in the body cavity can be used in various body cavities of the human body that communicate with the outside world, such as the anus, vagina, nasal cavity, and oral cavity. When used, this electrode does not need to use conductive liquid and any medicine. When it is used alone, a circuit is formed by the two electrodes and the body fluid in the body cavity; when it is used together with the external electrode, the circuit is formed by the electrode in the body cavity and the body fluid used by the external electrode.
