[0031] 2% xanthan gum, 0.1% carbomer, 5% glycerol, 4% traditional Chinese medicine, 88.9% purified water;

[0032] Preparation:

[0033] (1) Mix Coptis, Houttuynia cordata, Pulsatilla, Licorice, and Fuling according to the weight ratio of 3:1:1:2:0.5. Use 5 times the weight of water to decoct twice, filter, combine the filtrate, and decolorize , Concentrated to a relative density of 1.2-1.3, that is, a traditional Chinese medicine liquid;

[0034] (2) Mix the Chinese medicinal liquid and purified water evenly, add glycerol, xanthan gum, and carbomer in sequence, and stir evenly to obtain.

Embodiment 3

[0036] A medical disinfectant ultrasonic coupling agent, the raw material weight percentage is as follows:

[0037] Xanthan gum 2%, carbomer 0.3%, glycerol 6%, traditional Chinese medicine 6%, purified water 85.7%;

[0038] Preparation:

[0039] (1) Mix Coptis, Houttuynia cordata, Pulsatilla, Licorice, and Fuling according to the weight ratio of 3:1:1:2:0.5. Use 5 times the weight of water to decoct twice, filter, combine the filtrate, and decolorize , Concentrated to a relative density of 1.2-1.3, that is, a traditional Chinese medicine liquid;

Abstract

The invention relates to the technical field of couplants, and in particular relates to a medical disinfecting ultrasonic couplant. The couplant contains the following raw materials in percentage by weight: 0.5-2% of xanthan gum, 0.1-0.5% of carbomer, 5-8% of glycerol, 4-6% of a traditional Chinese medicine solution and 50-90% of purified water. A preparation method of the couplant comprises the following steps: mixing coptis chinensis, houttuynia cordata, Chinese pulsatilla root, liquorice and poria cocos at a weight ratio of 3: 1: 1: 2: 0.5, decocting twice in 5 times of water by weight, filtering, combining filtrate, decoloring an concentrating until relative density is 1.2-1.3, thus obtaining the traditional Chinese medicine solution; and uniformly mixing the traditional Chinese medicine solution and the purified water, sequentially adding the glycerol, the xanthan gum and the carbomer, and uniformly stirring to obtain the couplant. The medical disinfecting ultrasonic couplant disclosed by the invention is excellent in ultrasonic image and stable in performance, and is applicable to various ultrasonic detections; the medical disinfecting ultrasonic couplant is good in disinfecting effect, and capable of avoiding cross infection and enhancing the ultrasonic detection safety.

Description

technical field [0001] The invention relates to the technical field of couplants, in particular to a medical sterilized ultrasonic couplant, and also relates to a preparation method of the medical sterilized ultrasonic couplant. Background technique [0002] Ultrasound couplant used in hospital ultrasonography, its function is to expel air and form a channel for smooth and undistorted transmission of ultrasonic waves. The best dosage form recommended clinically is gel, and the coupling agent also acts as a lubricant. In the early 1970s, the U.S. patent put forward 10 requirements for "ultrasonic coupling gel". Although it has gone through more than 30 years, it still seems outdated now. Its content is: (1) equal to the sound velocity of human tissue to ensure that the shape of the ultrasonic beam will not be distorted; (2) the attenuation coefficient is very small, which will not reduce the signal-to-noise ratio, which is conducive to the detection of weak echo signals; (...
