Energy mediation liquid used for extracorporeal shock wave lithotripsy, and preparation method of energy mediation liquid

Abstract

The invention relates to an energy mediation liquid, in particular to an energy mediation liquid used for extracorporeal shock wave lithotripsy, and a preparation method of the energy mediation liquid, and belongs to the field of medical apparatus and instruments. The energy mediation liquid used for the extracorporeal shock wave lithotripsy consists of the following ingredients in parts by weight: 1-15% of organic solvent, 0.05-1% of electrolyte, 0.05-1% of defoamer, 0.1-0.5% of metal ion chelating agent, 0.5-1% of viscosity modifier and deionized water. The invention aims to overcome the deficiencies of a treatment technology when a urinary system stone receives the extracorporeal shock wave lithotripsy at present, the shock wave energy mediation liquid which has stable properties, is safe and reliable and is conveniently manufactured is provided, and the problems that the energy of a shock wave is likely to be lost during common water quality conduction, a focusing capability is lowered after ageing and certain side effects occur during or after treatment can be solved.

Description

technical field [0001] The invention relates to an energy mediation liquid, in particular to an energy mediation liquid for extracorporeal shock wave lithotripsy and a preparation method thereof, belonging to the field of medical devices. Background technique [0002] The extracorporeal shock wave lithotripsy technology uses the shock waves emitted by the lithotripter to focus on the stones through the contact between the skin and the machine, and shatter the stones. Crushed stones are passed naturally in the urine. Extracorporeal shock wave lithotripsy uses shock waves to generate compressive stress (the interface before the stone) and tensile stress (the interface after the stone) at the interface of two propagation media with different acoustic impedances, the tissue and the stone, so that the stone is gradually peeled off and broken from the surface, and will not be able to expel itself It is a method for the treatment of urinary calculi by breaking the large stones int...

AI Technical Summary

Problems solved by technology

At present, most of the water used for extracorporeal shock wave lithotripsy is tap water or distilled water. There is no standard standard for the degree of ionization and viscosity of water, and it is easy to age after multiple shock waves pass through, so the effect of lithotripsy cannot be guaranteed.

The energy of the shock wave is easily lost in ordinary water quality conduction, and the focusing ability decreases after aging. There will also be some side effects during or after treatment.
