Extracorporeal shock wave therapy handle with adjustable volume

Abstract

The invention discloses an extracorporeal shock wave therapy handle with an adjustable volume. The extracorporeal shock wave therapy handle comprises a gas pipe, a cone, a gas pressure inlet, a therapy head, an outer gas chamber and a volume adjusting device, wherein the cone can move in a reciprocating way in the gas pipe; the gas pressure inlet is arranged at one end of the gas pipe; the therapy head is arranged at the other port of the gas pipe; the outer gas chamber is communicated with the gas pipe so that gas in the outer gas chamber can enter the gas pipe and a rebound speed of the cone is improved; and the volume adjusting device is used for adjusting the volume of the outer gas chamber 4. According to the extracorporeal shock wave therapy handle with the adjustable volume, provided by the invention, extracorporeal shock wave therapy is carried out by utilizing a pneumatic ballistic shock wave source; and the extracorporeal shock wave therapy handle is high in accuracy, low in energy consumption, small in volume and convenient and flexible to use.

Description

technical field [0001] The invention relates to the field of rehabilitation medical equipment, in particular to a volume-adjustable extracorporeal shock wave therapy handle. Background technique [0002] Shock wave is a mechanical pulse strong wave (high-energy pressure wave generated by the sudden release of its energy) that is transmitted through a physical mechanical medium (such as air, water), and can give multiple frontal waves in a short time. The characteristics of instantaneous pressure increase and high-speed conduction. The shock wave therapy instrument converts the pulsed sound waves generated by compressed air through program control into high-precision ballistic shock waves. Using the unique frequency of the instrument, it acts on the trigger points of the human body through the positioning and movement of the treatment head to improve the impact of the trigger points. Regional dysfunction, decomposes accumulated metabolites, stimulates the muscles in the affe...

AI Technical Summary

Problems solved by technology

[0003] Existing shock wave therapy apparatus has the following deficiencies: one, the cone can slide freely in the trachea, which leads to the fact that the cone is not at the inlet port of the trachea when the gas control valve fills the trachea with high-pressure gas instantaneously (cone The body is in the middle of the trachea), resulting in differences in the impact of the impact head due to the different sliding strokes of the cone each time, resulting in instability of the treatment effect and affecting the treatment; 2. The structure of the treatment handle is complex and easy to damage, resulting in The energy of the cone is small, and the gas cannot be discharged smoothly; 3. When the input air pressure is changed according to the treatment needs, the rebound speed of the cone does not match the sliding speed, which affects the treatment effect
