Sterilizing-and-disinfecting-type coupling agent and preparing method thereof

Abstract

The invention discloses a sterilizing-and-disinfecting-type coupling agent and a preparing method thereof. The sterilizing-and-disinfecting-type coupling agent is prepared from, by mass, carbomer 940, propylene glycol, glycerine, vitamins B5, polyvinylpyrrolidone K30, triclosan, methyl parahydroxybenzoats, triethanolamine, lauryl sodium sulfate and purified water. Compared with the prior art, the sterilizing-and-disinfecting-type coupling agent is good in stickiness and skin compatibility, and has good infiltrating performance for the skin and an ultrasonic probe, and the problems that an existing coupling agent is poor in stickiness and excessively short in drying time can be solved; due to the synergistic effect of the triclosan and the methyl parahydroxybenzoats in the formula, the coupling agent achieves safe and stable sterilization and bacteriostasis; the cytotoxicity of the coupling agent is greatly reduced, and use safety is high; the skin irritation of the coupling agent is low, and repairing of injured skin can be promoted at the same time through components with the repairing function in the formula. The preparing method of the coupling agent is simple, and industrial production can be easily achieved.

Description

technical field [0001] The invention relates to a coupling agent and a preparation method thereof, in particular to a sterilizing and disinfecting medical ultrasonic coupling agent and a preparation method thereof, belonging to the technical field of medical ultrasonic imaging agents. Background technique [0002] Ultrasound is a sound wave with a frequency above 20,000 Hz. Ultrasound can propagate in a certain direction and can penetrate objects. If it encounters obstacles, it will generate echoes. Different obstacles will produce different echoes. People pass through The instrument collects this echo and displays it on a screen, which can be used to understand the internal structure of the object. [0003] Using this principle, people use ultrasound to diagnose and treat human diseases. Ultrasound propagates in the human body. Due to the differences in the acoustic characteristics of various tissues of the human body, the ultrasonic wave produces reflection, refraction, s...

Problems solved by technology

[0009] The object of the present invention is to provide a sterilizing and disinfecting coupling agent for the deficiencies of the prior art. The sterilization and disinfecting coupling agent is prepared from components with good water solubility and no corrosive effect on the ultrasonic probe, which is non-destructive to the ultrasonic probe and plays a role The function of protecting the probe; the coupling agent uses dichlorophenoxychlorophen as the bactericide and methyl p-hydroxybenzoate as the bacteriostatic agent, and the synergistic effect of the two can achieve safe and stable bactericidal and bacteriostatic in the formula; The couplant has good viscosity, good compatibility with the skin, and good wetting performance with human skin and ultrasonic probes, which can solve the problems of poor adhesion and too fast drying time of the existing couplant; the couplant The cytotoxicity is greatly reduced, and the use safety is high; the irritation to the skin is low, and the components with repair function in the formula can promote the repair of damaged skin at the same time
