In the B-ultrasound examination room, the doctor squeezed the medical coupling agent on your stomach, and it felt a bit cool. It looks crystal clear and a bit like your usual (cosmetic) gel. Of course, you are lying on the examination bed and can’t see it on your stomach.
Just after you have finished the abdominal examination, while rubbing the “Dongdong” on your stomach, muttering in your heart: “Smudged, what is it? Will it stain my clothes? Is it toxic?”
Your fears are superfluous. The scientific name of this “eastern” is called a coupling agent (medical coupling agent), and its main components are acrylic resin (carbomer), glycerin, water, and the like. It is non-toxic and tasteless and very stable in everyday environments; in addition, it does not irritate the skin, it does not stain the clothes, and it is easily erased.
So, after the inspection, take a few sheets of paper that the doctor will hand you, you can safely wipe it clean, leave it with a sigh of relief, without taking a trace of worry.
However, why should B-ultrasound use this medical couplant?
Because the ultrasonic waves used in the inspection cannot be conducted in the air, and the surface of our skin is not smooth, the ultrasonic probe will have some tiny gaps when it comes into contact with the skin, and the air in this gap will hinder the penetration of the ultrasonic waves. . Therefore, a substance (medium) is needed to fill these tiny gaps, which is a medical couplant. In addition, it also improves display clarity. Of course, it also acts as a “lubrication”, reducing the friction between the probe surface and the skin, allowing the probe to be flexibly swept and probed.
In addition to the B-ultrasound of the abdomen (hepatobiliary, pancreas, spleen and kidney, etc.), the thyroid gland, the breast and some blood vessels are examined, etc., and medical couplants are also used.
