Abstract

The invention discloses a pulsed magnet field analgesic apparatus. According to the pain sensory nerve conduction and control mechanism and the effective clinical basis of transcutaneous electrical stimulation and transcranial magnetic stimulation analgesia, a side-effect-free, efficient and safe pulsed magnetic stimulation analgesic apparatus and an analgesic operation method are designed. A maincircuit emits pulse current to a stimulation coil by an energy-storage capacitor with the adjustable voltage through a full-bridge switch circuit, a pulsed magnet field is generated for analgesia, the alternating current-direct current and direct current-direct current voltage conversion process is adopted, equipment electromagnetic interference is removed through an alternating-current power supply filtration module, alternating current is rectified through a rectifying module to form direct current, and the circuit is adjusted through power factors so that the current waveform of equipmentcan be coincident with the voltage waveform of the equipment; through a direct current-direct current voltage conversion boosted circuit, a resonant soft switching constant-current charging module, avoltage comparator and a feedback circuit, the energy-storage capacitor is charged to the set level through a microprocessor.

Description

technical field [0001] The invention belongs to the technical field of magnetic therapy analgesia, in particular to a pulsed magnetic field percutaneous stimulation device and an analgesic method for inhibiting pain nerve excitability. Background technique [0002] Pain is an unpleasant emotion and feeling produced by nerve stimulation caused by injury. Treating pain is a long-term problem in modern medicine. [0003] Common pain treatment drugs such as morphine and pethidine, but long-term use will have addictive side effects; electrical stimulation needs to use electrodes to contact the skin, which will produce electrochemical reactions or allergic reactions on the skin and produce new stimulation pain; surgery Surgical electrical stimulation implants electrical stimulation electrodes and stimulation generators in the body, which is expensive and traumatic, and the surgery will also damage the structure of nerve tissue; transcranial magnetic stimulation, a non-invasive n...
