Abstract
Description
technical field
[0001] The invention relates to a medical ultrasonic coupling agent and a preparation method thereof, in particular to a bactericidal medical ultrasonic coupling agent for invasive medical ultrasonic diagnosis and treatment and a preparation method thereof. Background technique
[0002] Medical ultrasonic coupling agent is a sound-transmitting medium widely used in medical ultrasonic diagnosis and treatment at present. Its function is to strengthen the coupling between the ultrasonic probe and human skin, isolate the air between the ultrasonic probe and the skin of the examined part, and make the sound wave conduction unaffected. Attenuated by the influence of air to achieve accurate and clear inspection results.
[0003] Since the ultrasonic probe is in contact with the body skin or cavity mucous membrane of the subject, the disinfection treatment of the ultrasonic probe itself becomes very important. However, the existing medical ultrasonic coupling agents...
Examples
Embodiment 1
[0044] Prepare a sterile grade sterilized medical ultrasonic coupling agent for invasive ultrasonic diagnosis and treatment with a total weight of 1000 grams:
[0045] In the first step, 0.1 gram of 2,4,4'-trichloro-2'-hydroxyl diphenyl ether was dissolved in 40 grams of glycerol and allowed to stand for 12 hours;
[0046] In the second step, 6 grams of cross-linked polyacrylic resin and 5 grams of hydroxyethyl cellulose are dissolved in 250 grams of distilled water to obtain a mixed solution of cross-linked polyacrylic resin and hydroxyethyl cellulose;
[0047] In the third step, 100 grams of hydroxyethyl chitosan and 1 gram of triethanolamine are dissolved in 200 grams of distilled water;
[0048]The 4th step, the glycerol solution containing 2,4,4'-trichloro-2'-hydroxyl diphenyl ether obtained in the first step is added under stirring the cross-linked polyacrylic resin obtained in the second step and In the mixed solution of hydroxyethyl cellulose, continue to stir for 5 m...
