Medical ultrasonic coupling agent with disinfection function and preparation method

Abstract

The invention relates to a medical ultrasonic coupling agent with a sterilization function and a preparation method, and belongs to the technical field of coupling agent processing. The medical ultrasonic coupling agent is prepared from the following components in parts by weight: 8-10 parts of carbomer, 0.08-0.11 part of o-phthalaldehyde, 0.1-0.5 part of chlorhexidine gluconate, 0.1-0.3 part of polyethylene glycol, 0.04-0.07 part of propylene glycol, 50-70 parts of glycerol, 1-5 parts of sodium hydroxide, 1-4 parts of menthol, 0.1-0.5 part of hydroxypropyl methyl cellulose and 900-1000 parts of purified water. The medical ultrasonic coupling agent has good biocompatibility, coupling property and stability, and can effectively ensure the definition and accuracy of ultrasonic instrument inspection and use; and the medical ultrasonic coupling agent is mild in performance, does not irritate the skin, can kill the growth of bacteria, avoids cross infection, and is easy to clean. According to the medical ultrasonic coupling agent with the sterilization function, o-phthalaldehyde and chlorhexidine gluconate are compounded for use, so that a synergistic interaction effect is achieved. The menthol can promote the contact between the o-phthalaldehyde and the chlorhexidine gluconate and disinfection substances, so that the disinfection and sterilization effects are improved.

Description

technical field [0001] The invention relates to a medical ultrasonic coupling agent with bactericidal function and a preparation method thereof, belonging to the technical field of coupling agent processing. Background technique [0002] With the development of society, ultrasound technology is used more and more in medical equipment, and it is widely accepted because of its high diagnostic accuracy and good therapeutic effect. Ultrasound equipment needs to use couplant during inspection. Its purpose is to strengthen the coupling between the ultrasonic probe and human skin, to isolate the air between the ultrasonic probe and the skin of the inspected part, so that the sound wave conduction is not affected by the air and attenuated, so as to Achieve clear imaging effect and accurate diagnosis results. With the increasing demand of national health administrative departments to control cross-contamination in hospitals, the production and marketing of medical ultrasonic couplin...
