Embodiment 1

[0017] A sterilizing medical ultrasonic coupling agent comprises hydroxyethyl cellulose, propylene glycol and deionized water, and also includes 1‰ (mass ratio) of vitamin B5 and 0.5‰ (mass ratio) of sodium lauryl ether sulfate. The method for preparing the above disinfection and sterilization medical ultrasonic coupling agent is: disperse hydroxyethyl cellulose in propylene glycol, add enough deionized water to stir and disperse, heat to 75°C, keep warm for 30min, wait until the liquid is transparent, cool to room temperature, add 1‰ (mass ratio) vitamin B5, 0.5‰ (mass ratio) sodium lauryl ether sulfate, stir evenly, and pack in cans.

Embodiment 2

[0019] A disinfecting and sterilizing medical ultrasonic coupling agent includes carbomer, propylene glycol and deionized water, and also includes 3‰ (mass ratio) of vitamin B5 and 3‰ (mass ratio) of sodium lauryl ether sulfate. The method for preparing the above-mentioned disinfecting and sterilizing medical ultrasonic coupling agent is: disperse hydroxyethyl cellulose in propylene glycol, add enough deionized water to stir and disperse, heat to 80°C, keep warm for 30min, wait until the liquid is transparent, cool to room temperature, add 1‰ (mass ratio) vitamin B5, 0.5‰ (mass ratio) sodium lauryl ether sulfate, stir evenly, and pack in cans.

Embodiment 3

[0021] A sterilizing medical ultrasonic coupling agent comprises hydroxypropyl cellulose, propylene glycol and deionized water, and it also includes 1‰ (mass ratio) of vitamin E and 0.5‰ (mass ratio) of coconut oil diethanolamide. The method for preparing the above-mentioned disinfecting and sterilizing medical ultrasonic coupling agent is: disperse hydroxyethyl cellulose in propylene glycol, add enough deionized water to stir and disperse, heat to 80°C, keep warm for 30min, wait until the liquid is transparent, cool to room temperature, add 1‰ (mass ratio) of vitamin E, 0.5‰ (mass ratio) of coconut oil diethanolamide, stir evenly, and pack in cans.

Abstract

The invention relates to a sterilizing type medical ultrasonic coupling agent which comprises a viscosity regulator and a germicide, wherein the viscosity regulator is selected from one of hydroxyethyl cellulose, carbomer and hydroxy propyl cellulose, propylene glycol and deionized water. The medical ultrasonic coupling agent is characterized by also comprising 0.1-0.3 percent of any one or a combination in an arbitrary proportion of vitamin B5 and vitamin E. Components of the germicide are selected from any one or a composition in an arbitrary proportion of lauryl ether sodium sulfate and cocosulfate diethanloamide, and the proportion of the germicide to the whole coupling agent is 0.05-0.3 percent. The coupling agent is more suitable for the skin and has lower cost. The invention also provides a preparation method of the sterilizing type medical ultrasonic coupling agent.

Description

(1) Technical field: [0001] The invention relates to a medical ultrasonic coupling agent, in particular to a sterilizing medical ultrasonic coupling agent used in ultrasonic diagnosis and treatment and a preparation method thereof. (two) background technology: [0002] In the prior art, medical ultrasonic coupling agents commonly used in clinical ultrasonic diagnosis and treatment are mainly prepared from one of the viscosity modifiers such as hydroxyethyl cellulose, carbomer, and hydroxypropyl cellulose, propylene glycol solvent, and deionized water. become. It acts as a coupling between the sound head (ultrasound probe or treatment head) and the measured object, so that the sound waves can enter the body smoothly to obtain reliable images or reach the treated tissue. Its basic requirement is that it can effectively transmit sound waves, and the acoustic impedance rate is between the acoustic impedance rate of the acoustic head and human tissue. They can be properly matche...
