Abstract

The invention relates to a medical ultrasonic coupling agent with disinfection and sterilization functions. The weight percentage of the ingredients is: 0.2-2% of 2,4,4'-trichloro-2'-hydroxydiphenyl ether, 4-7% of glycerol, Cross-linked polyacrylic acid resin 0.6-1.5%, sodium hydroxide 0.8-1.2%, distilled water 89.0-94.0%. The preparation steps are as follows. In the first step, 2,4,4'-trichloro-2'-hydroxydiphenyl ether and glycerol are weighed by weight percentage, and 2,4,4'-trichloro-2'- The hydroxydiphenyl ether is completely dissolved in the glycerin solution and left in place; in the second step, the cross-linked polyacrylic acid resin is weighed by weight percentage and dissolved in distilled water; the solution obtained in the first step is added into the second step under stirring to obtain The solution was then supplemented with distilled water and sodium hydroxide solution to make a gel. The invention can sterilize the ultrasonic probe during the inspection process, reducing cross infection; the preparation process is simple, and the environment is not polluted.

Description

technical field [0001] The invention relates to a medical ultrasonic coupling agent with disinfection and sterilization functions and a preparation method thereof. Background technique [0002] The function of the traditional medical ultrasonic coupling agent 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 a good detection effect . CN1087016A discloses that "the preparation method of medical ultrasonic coupling agent" is to take 5 grams of CPB-1 series acrylic polymer, namely Carboresin-1 type, and put it in water for 5-6 hours to make it swell, and then add 20% sodium hydroxide Make the pH of the solution between 6.8 and 7.2, then add sodium benzoate and glycerin, stir evenly and add water to 1000ml. The medical ultrasonic coupling agent prepared by this method has no fu...
