Protection device of electromagnetic type impact wave generator

Abstract

The invention discloses a protection device of an electromagnetic type impact wave generator. The protection device comprises a water bag, an electromagnetic disk and a metal shell, wherein the electromagnetic disk is formed by a fixing end and a working end, the metal shell is provided with a water through hole, the end surface of the fixing end is greater than the end surface of the working end, and a gas storage tank is formed by the working end of the electromagnetic disk, the inner wall of the metal shell and the water level of water flow in the water bag. According to the protection device disclosed by the invention, the inner part of an electromagnetic type impact wave transmitter is provided with a temporary gas storage structure, residual gas can be automatically stored in the gas storage tank without gathering on the working surface of the electromagnetic disk, and thus the normal work of the electromagnetic disk can be ensured; a circulation cooling device is used for cooling the water bag and the electromagnetic disk, and thus the service life of the electromagnetic disk can be prolonged; water discharge, gas discharge and water inlet pipelines are communicated with the bottom part of a water tank, thus the water quantity and the pressure in the water bag can be kept, and a treatment effect of an impact wave can be considered at the same time; water can be treated through a gas filter device before the water flow enters into the water bag, the damage of the residual gas in the water bag can be reduced, the structure is simple, and the protection device is very practical.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a protection device for an electromagnetic shock wave generator. Background technique [0002] The working principle of the electromagnetic shock wave generator is: the coil receives a high voltage instantly, generates a strong eddy current to push the metal diaphragm to send out a shock wave, and transmits the force to the designated target through the conduction of water. There is also a by-product of this process: heat. [0003] The electromagnetic wave transmitter can be applied to the electromagnetic shock wave generator of extracorporeal shock wave medical equipment. When working, the electromagnetic wave generator is in a tilted upside-down state, and water is used as the medium for shock wave transmission; before the shock wave works, it must be filled with water. It will drive the gas to enter together. At this time, the gas is in contact with the working surf...

Problems solved by technology

[0006] The purpose of the present invention is to solve the defects in the prior art that the water flow in the shock wave transmitter has residual gas that will affect the conduction of the shock wave and that the long-term use will cause the internal water temperature to be too high and affect the therapeutic effect, and provide protection for the electromagnetic shock wave generator. device to solve the above problems
