U-shaped electromagnetic oscillation physiotherapy instrument
Technical Field
The invention relates to a U-shaped electromagnetic oscillation physiotherapy instrument, and belongs to the technical field of production of physiotherapy instruments.
Background
At present, various physical therapeutic apparatuses such as field effect therapeutic apparatuses, high, medium and low frequency and direct current electronic therapeutic apparatuses, pulse therapeutic apparatuses and the like in the market and the medical field act physical factors such as light, electricity, temperature, infrared, constant magnetism and the like on a human body so as to achieve the effects of treatment, health care and the like, and most of the field effect therapeutic apparatuses act on the affected parts or acupuncture points of the human body through electrodes. However, some instruments have some defects in different degrees, such as only acting on the surface or acupuncture points of the affected part, and also such as low-frequency and direct-current physiotherapy, the current is not easy to pass through the air gap between the electrode and the skin, so the electrode cannot leave the skin surface, and is inconvenient to apply to the uneven surface; shortwaves and ultrashort waves have the disadvantage of easily overheating subcutaneous fat when capacitive electrodes are used.
Disclosure of Invention
In order to overcome the above-mentioned drawbacks of some physiotherapy products, the present invention provides a simple and easy-to-use U-shaped electromagnetic physiotherapy apparatus.
The technical scheme adopted by the invention for solving the technical problems is as follows: u-shaped electromagnetic oscillation physiotherapy equipment contains circuit part and instrument entity (like attached figure one), its characterized in that: a U-shaped open-loop magnetic circuit is creatively formed by a 1 electromagnetic pole plate A, a 3 electromagnetic pole plate B and a 6 magnetic conduction bottom plate which are made of silicon steel sheets, and the magnetic circuit is fixed through a 5 fixing clamping plate. The device comprises a signal generating circuit, a speed adjusting circuit, an amplitude adjusting circuit, a signal driving circuit and an electromagnetic polarity conversion circuit, wherein 220V alternating current is input and then converted into a direct current power supply, time-selectable and timing control is carried out, real-time speed display or human pulse signal extraction and amplification is carried out through the signal generating circuit and the speed adjusting circuit, real-time amplitude current display is carried out through the amplitude adjusting circuit, the signal driving circuit and the electromagnetic polarity conversion circuit, large current with alternating positive and negative polarities is output to a 4 conductive coil arranged at the bottom of a. According to the principle of physics, alternating 2-shaped lines of force are inevitably formed between the electromagnetic pole plate A1 and the electromagnetic pole plate B3, the affected part of the human body is arranged between the two U-shaped electromagnetic pole plates, and the alternating lines of force are inevitably applied to the affected part of the human body. The effect is that local eddy current is generated at the affected part of the human body due to the passing of the magnetic force line; and secondly, the alternation of magnetic lines of force promotes the positive and negative charges in the body of the affected part to be alternated along with the alternation of the magnetic lines of force, so as to achieve the effects of dredging the biological circuit, channels and collaterals, qi and blood and activating the functions of organs of the human body.
The invention has the advantages of simple and reliable circuit, and capability of adjusting the amplitude of the oscillating current to enable the magnetic force lines to penetrate through the whole affected part of the human body, thereby achieving the purpose of treating the focus. For example, epilepsy is due to abnormal neuronal bioelectrical pathways in focal regions of brain tissue, and when the potential difference reaches a critical threshold, it discharges at high frequency and spreads to the periphery, resulting in transient complex dysfunction of brain. The treatment by the method can effectively dredge biological circuits and channels of focus, the low-frequency alternating magnetic force acts on a human body, no abnormal feeling is generated to the human body, and the electric shock acupuncture feeling that the pulse voltage contacts the human body through the electrode can not occur.

Detailed Description
As shown in the figure I, a coil 4 is placed at the bottom of a U-shaped silicon steel sheet, 220V alternating current is input, then the instrument is converted into a direct current power supply and can be controlled at a timing with optional time, a signal generating circuit is arranged on an internal circuit board, a panel potentiometer is controlled to adjust the signal rate and display the signal in real time or extract and amplify pulse signals of a human body, a potentiometer is arranged to adjust the amplitude of oscillation current in a control range and indicate the amplitude of the oscillation current in real time by an ammeter, a pulse signal is driven and amplified by a transistor and alternately change the positive direction and the negative direction of the current to flow into the coil 4, so that a magnetic line of force with alternating N-S polarity is formed between the electromagnetic pole plates 3 and 1, and the magnetic line of force inevitably penetrates through a focus between the two electromagnetic pole plates because a human body cannot shield; the alternation of the magnetic lines of force causes the positive and negative charges in the affected part to be alternated with the magnetic lines of force, so as to achieve the effects of dredging the biological circuit, channels and collaterals, qi and blood and activating the functions of organs of the human body. In the second figure, the rubber foot margin of the instrument 1 can be horizontally placed from side to side, so that different positions and body positions are convenient; 2, the two heavy handles are arranged on the electromagnetic polar plate to facilitate transportation; 3, wrapping buffer padding leather outside; 4, a circuit board is arranged in the electric control cabinet, a power line is led in the bottom of the electric control cabinet, and a cooling fan is arranged to ventilate the outside; 5, various control knob switches and instruments are arranged on the control panel; 6 the bottom plate roller is convenient to move, and the size and the distance of the two polar plates can be manufactured into different specifications or movable polar plates according to requirements. The amplitude adjustment can be set to be 2 or more than 2, and an electric lock switch and a timer are installed.
