Medical disinfecting and sterilizing ultrasonic coupling agent and preparation method thereof

Abstract

The invention discloses a medical disinfecting and sterilizing ultrasonic coupling agent and a preparation method thereof. The ultrasonic coupling agent comprises 0.1 to 2 percent of R-polysaccharide, 2 to 7 percent of propylene glycol, 2 to 7 percent of glycerol, 0.6 to 1.5 percent of crosslinking (polyacrylic acid) resin, and 82.8 to 95.3 percent of distilled water; and in addition, triethanolamine is added in an amount which is 0.8 to 1.2 percent based on the total weight of the above materials. The preparation method comprises the following steps: preparing mixed solution of propylene glycol and glycerol; completely dissolving the R-polysaccharide in the prepared mixed solution; preparing solution of crosslinking (polyacrylic acid) resin; adding the prepared mixed solution containing the R-polysaccharide into the solution of crosslinking (polyacrylic acid) resin to obtain a gelatinous polymer, supplementing distilled water and stirring the solution uniformly; and slowly dripping solution of triethanolamine to neutralize the obtained ultrasonic coupling agent. In the invention, the problem that effective disinfection cannot be realized in a short time is solved and the preparation process is simple.

Description

technical field [0001] The invention relates to the preparation of a coupling agent between a medical instrument probe and human skin, in particular 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 good detection results . The "preparation method of medical ultrasonic coupling agent" disclosed by CN1087016A is to first get 5 grams of CPB-1 series acrylic acid polymer (i.e. Carboresin-1 type substance) and put it into water for 5-6 hours, after making it expand, add 20 % sodium hydroxide solution to make the pH between 6.8 and 7.2, then add sodium benzoate and gly...

AI Technical Summary

Problems solved by technology

[0003] (1) There is no suitable compound, and the particularity of the ultrasonic probe material determines that most of the disinfectants on the market that are corrosive and swellable to this plastic and rubber cannot be used for the disinfection of ultrasonic probes;

[0004] (2) There is no suitable medium, and the particularity of the structure of the ultrasonic probe makes it impossible to use the most commonly used soaking method for disinfection, and the requirements for the medium are high;

[0005] (3) Disinfection time. Due to the high frequency of work, the interval between patients under test is very short, usually about 1 minute. Disinfectants that can simultaneously kill bacteria, mold and viruses in such a short period of time are not yet on the market.

However, the preparation process is relatively complicated, and it is inconvenient to add water and stir when using
