B-mode ultrasound coupling agent and its prepn

Abstract

The coupling agent for B-mode ultrasound diagnostic instrument consists of povidone-iodine 0.5-5 %, glycerin 1-7 %, sodium carboxy methyl cellulose 3-6 %, ethanol 10-15 % and pure water 67-85.5 %. During its preparation, povidone-iodine is first dissolved in water, sodium carboxyl methyl cellulose and ethanol are mixed homogeneously through stirring, the povidone-iodine solution is then mixed with mixed sodium carboxy methyl cellulose and ethanol solution through stirring, and the mixed solution is 80-120 mesh filtered to obtain the coupling agent. The coupling agent is used in supersonic test in hospital and can kill bacteria and virus and prevent crossed infection.

Description

technical field [0001] The invention relates to the technical field of B-ultrasonic coupling agent and 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 --- B-ultrasound couplant, to fill the tiny space between the probe and the skin surface. In order to obtain clear and high-resolution ultrasonic images; ultrasonic inspection not only requires a dedicated ultrasonic probe, but also requires a small sound attenuation coefficient, sound velocity and acoustic impedance similar to human tissue, excellent acoustic performance, non-toxic and non-irritating to the human body , no sensitization, B-ultrasound coupling agent with good biocompatibility, and at present, the commonly used B-ultrasound coupling agent is...

[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 --- B-ultrasound couplant, to fill the tiny space between the probe and the skin surface. In order to obtain clear and high-resolution ultrasonic images; ultrasonic inspection not only requires a dedicated ultrasonic probe, but also requires a small sound attenuation coefficient, sound velocity and acoustic impedance similar to human tissue, excellent acoustic performance, non-toxic and non-irritating to the human body , no sensitization, B-ultrasound coupling agent with good biocompatibility, and at present, the commonly used B-ultrasound coupling agent is a colloid solution composed of glycerin, sodium carboxymethylcellulose, ethanol, and purified water. Coupling effect cannot kill bacteria and viruses, causing cross-infection of B-ultrasound probes during use and damaging the health of patients
