Problems solved by technology

However, most of the existing ultrasonic couplants are prepared by mixing water phase and oil phase. The couplant is not very water-soluble and difficult to dissolve in water. It is not easy to clean after the inspection, especially if the clothes are soiled during the smearing process, which is difficult to clean. bigger

Abstract

The invention discloses a water-based medical ultrasonic couplant and a preparation method and an application method thereof, which belong to the technical field of the medical ultrasonic couplant. The water-based medical ultrasonic couplant comprises the following raw materials in parts by weight: 40-80 parts of liquidambar formosana hance, 30-50 parts of tree peony bark, 35-60 parts of Scutellaria baicalensis, 35-60 parts of Sophora flavescens, 40-80 parts of cactus, 50-80 parts of pine needle, 60-90 parts of oat, 50-90 parts of bamboo shavings, 45-65 parts of mushroom, 60-90 parts of freshand tender towel gourd, 20-50 parts of rose flower, 20-40 parts of perilla, 20-40 parts of lithospermum, 35-50 parts of fish pelargonium, 30-50 parts of bergamot, 20-40 parts of starch wheat, 5-20 parts of phycocyanin, and 5-10 parts of sodium polyacrylate. The prepared ultrasonic couplant employs water as a solvent and takes traditional Chinese medicine plant extract products as a main component,water-soluble performance is strong, smearing effect is good, washing difficulty after smearing is little, nontoxicity and innocuousness cannot be generated on human body, and no pollution is generated for environment.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic coupling agent, in particular to a water-based medical ultrasonic coupling agent and its preparation method and use method. Background technique [0002] When ultrasonic waves are incident on the interface between two different media, the greater the difference in impedance between the two media, the greater the reflection coefficient, and the less sound energy that passes through the interface into another medium. For medical ultrasound, if the probe is in "dry contact" with the skin, the ultrasonic waves emitted by the probe cannot enter the human body at all due to the strong reflection of the air layer between the two. For this reason, a certain substance must be filled between the surface of the probe and the skin to drive out the air and form a channel for the smooth and undistorted transmission of ultrasonic waves. This substance is called a medical ultrasonic coupling agent. ...
