Couplant for ultrasound and preparation method thereof

Abstract

The invention relates to a couplant for ultrasound and a preparation method thereof. The couplant comprises the following components in percentage by weight: 2-4 percent of chlorhexidine iodine, 3-6 percent of glycerol, 3-6 percent of sodium carboxymethyl cellulose, 12-15 percent of ethanol and 70-82 percent of deionized water. The preparation method of the couplant comprises the following steps of: adding the chlorhexidine iodine into the deionized water and dissolving to obtain a chlorhexidine iodine solution; adding sodium carboxymethyl cellulos into the ethanol and evenly stirring to obtain a mixed solution of the sodium carboxymethyl cellulos and the ethanol; and fully stirring and mixing the chlorhexidine iodine solution and the mixed solution of the sodium carboxymethyl cellulos and the ethanol to obtain the couplant for ultrasound. The invention has simple preparation process, kills bacteria and virus, has excellent functions for avoiding cross-infection and preventing hospital infection and is suitable for ultrasound examination of various hospitals.

Description

technical field [0001] The invention relates to an ultrasonic coupling agent and a preparation method thereof, in particular to an ultrasonic coupling agent capable of preventing cross-infection and a preparation method thereof. Background technique [0002] In ultrasonic diagnosis, in order to maximize the transmission of ultrasonic energy into the investigated organs, it is necessary to coat the sound-conducting medium with excellent acoustic performance between the ultrasonic probe and the skin—the coupling agent for ultrasonic to fill the surface of the probe and the skin. Clear and high-resolution ultrasound images can be obtained. The existing coupling agent for ultrasound only plays a coupling role and does not kill bacteria and viruses. However, the ultrasonic probe cannot be sterilized per person in actual work, which makes the probe very easy to cause cross-infection during use and damage the patient. of good health.
