Coupling agent for B ultrasound

Abstract

The invention relates to a coupling agent, in particular to a coupling agent for the B ultrasound. The coupling agent is prepared from natural indigo, alum, dried alum, gallnut, realgar, garlic, euphorbia lunulata, celandine, resina draconis, lithargite, glycerol, xanthan gum, carboxymethyl sodium cellulose, glycerol and deionized water. The coupling agent has the advantages that cross infection caused by using a pathogenic bacterium probe body on an ultrasonic diagnosis probe can be effectively avoided through contained traditional Chinese medicine ingredients; the coupling agent can have the disinfection function with the equivalent effect as that of a disinfecting agent, no injury is caused on the skin or a wound, and the effect of promoting healing is also achieved; a good B ultrasound window can be formed on the surface of the wound, and all subcutaneous structures of the wound of the patient can be well shown; the scheme is novel, the cost is low, and preparation is simple.

Description

technical field [0001] The invention relates to a couplant, in particular to a couplant for B-ultrasound. Background technique [0002] At present, the ultrasonic probe in ultrasonic examination is used repeatedly among patients at a high frequency, and usually it is simply wiped after use by the patient. Although it may not necessarily cause the patient to be infected with pathogenic bacteria, there is still a great risk of cross-infection. During ultrasonic testing, because the ultrasonic probe must be in close contact with the patient's skin, many germs can be cross-infected through the damaged skin of the patient, especially if there are wounds or other forms of damage on the skin surface of the testing site, ultrasonic testing will give Patients bring cross-infection. The root cause of cross-infection is caused by the germs carried by the ultrasound probe. Most of what we do now is to wipe the dirt on the probe with toilet paper until it cannot be seen by the naked eye...

AI Technical Summary

Problems solved by technology

2. At present, the common powerful disinfectants are often active in nature, which can not only react with pathogens, but also react with the human body, and can also react with the materials of the ultrasonic probe, which affects the service life of the probe

3. The active nature of the disinfectant often reacts with the probe and coupling agent, thus affecting the technical indicators of ultrasound

4. On the basis of solving the above problems, it is difficult to achieve rapid and powerful sterilization
