Hardware circuit of pain electric pulse therapy instrument

Abstract

The invention relates to a hardware circuit of a pain electric pulse therapy instrument. The hardware circuit comprises a microcontroller, a Bluetooth module, a boosted circuit, a pulse forming circuit, a USB bridge circuit, an LED indicating circuit, a power management module, a button module, a three-axis acceleration sensor and a lithium battery, wherein an output pin of the microcontroller isconnected to input ends of the Bluetooth module, boosted circuit, pulse forming circuit, USB bridge circuit, LED indicating circuit, power management module, button module and three-axis accelerationsensor separately, an output end of the boosted circuit is connected to the input end of pulse forming circuit, and an output end of the power management module is connected to the input end of the lithium battery. The hardware circuit of the pain electric pulse therapy instrument has the advantages that the used electric pulse frequency and pulse width are different from those of existing products, and a user can select the treatment intensity according to his / her own symptoms and use effects.

Description

technical field [0001] The invention relates to the technical field of medical systems, in particular to a hardware circuit of a pain electric pulse therapeutic apparatus. Background technique [0002] The purpose of pain treatment is to reduce or terminate pain attacks, relieve accompanying symptoms, and prevent pain recurrence. Treatment methods include drug therapy and non-drug therapy. Drug therapy has a certain degree of toxic and side effects, and patients may experience adverse reactions. [0003] Non-drug treatment is mainly physical therapy, which can use electrotherapy, magnetic therapy, psychological counseling to relieve stress, etc. Compared with drug treatment, its biggest advantage is that there will be no toxic side effects of drugs. [0004] In terms of electrotherapy, electrodes are usually placed on certain parts of the human body surface to apply electrical signals. Electrodes placed on the surface of the body are generally far away from the chest, and t...

Problems solved by technology

Electrotherapy mainly includes direct current therapy, direct current drug iontophoresis therapy, and low. In addition to a large amount of water in the human body, there are also many conductive electrolytes and non-conductive dielectrics. Therefore, the human body is actually a body with both resistance and capacitance properties. Complex conductor, which is the material basis of electrotherapy. The body responds differently to different types of electrical stimulation, and the treatment mechanism is also different. Low-frequency current can change the membrane potential of nerve and muscle cells, making them excited and contracting; low-frequency modulated medium-frequency current It can excite the thick fibers of sensory nerves and inhibit the afferent of thin fiber impulses, so the analgesic effect is strong, but the electric pulse frequency and pulse width of the existing therapeutic equipment are specific, and the specific output cannot be output through the microcontroller. Electrical pulse signal (Transcutaneous Electrical Nerve Stimulation-TENS) stimulates the sensory nerves on the upper part of the calf, inhibits and interrupts the transmission of pain information in the central nervous system through the microcontroller system
