Sterilization-type medical ultrasonic coupling agent and preparation method thereof

Abstract

The invention relates to a sterilization-type medical ultrasonic coupling agent and a preparation method thereof. The sterilization-type medical ultrasonic coupling agent comprises, by mass, 0.3-1% of carbomer 940, 3-10% of glycerin, 3-7% of propylene glycol, 0.3-1% of triethanolamine, 0.02-0.07% of triclosan, 0.02-0.07% of Kathon and 80-90% of deionized water. Kathon as an anticorrosive antibacterial agent is used according to a certain ratio and in preparation, a material mixing order is adjusted and a material temperature and a stirring rate are strictly controlled so that the technical problems of easy caking and more bubbles in production are solved. The sterilization-type medical ultrasonic coupling agent has good biocompatibility, no cytotoxicity to skin, no sensitization, no irritation and good sterilization and bacteriostasis effects, prevents human body cross infection, is safe and effective, has no peculiar smell and can be removed easily.

Description

technical field [0001] The invention relates to a couplant, in particular to a sterilizing medical ultrasonic couplant and a preparation method thereof. Background technique [0002] In the process of ultrasonic diagnosis and treatment, it is necessary to use an ultrasonic neutral medium that is filled or coated between the radiating surface of the probe and the human epidermis and mucous membrane to transmit sound waves, that is, medical ultrasonic coupling agent. Medical ultrasonic coupling agent is used in clinical applications. Among them, it forms a channel for the smooth and undistorted transmission of ultrasonic waves, and plays the role of a sound-transmitting medium. In clinical use, people not only pay attention to its acoustic characteristics, but also its safety and effectiveness. Whether it will affect the human body during use Cross-infection occurs. At present, there are many disinfection and bactericidal medical ultrasonic coupling agents on the market, that ...

[0002] In the process of ultrasonic diagnosis and treatment, it is necessary to use an ultrasonic neutral medium that is filled or coated between the radiating surface of the probe and the human epidermis and mucous membrane to transmit sound waves, that is, medical ultrasonic coupling agent. Medical ultrasonic coupling agent is used in clinical applications. Among them, it forms a channel for the smooth and undistorted transmission of ultrasonic waves, and plays the role of a sound-transmitting medium. In clinical use, people not only pay attention to its acoustic characteristics, but also its safety and effectiveness. Whether it will affect the human body during use Cross-infection occurs. At present, there are many disinfection and bactericidal medical ultrasonic coupling agents on the market, that is, a certain proportion of fungicides are added on the original basis, but many coupling agents added with fungicides are prone to agglomeration, many bubbles, etc. Problems that affect the quality and use of the couplant
