What is a coupling agent? Does the coupling agent have side effects?

What is a coupling agent? Coupling agent is a kind of polymer hydrogel, which generally has no influence and is transparent, colorless and tasteless. Generally, it can be divided into industrial coupling agents and medical coupling agents according to different uses. What we often hear is the coupling agent used in medical examination; Coupling agent is a sound transmission medium used in ultrasonic flaw detection, and it has different components according to different industry requirements.

Does the coupling agent have any side effects? Generally speaking, the side effects of coupling agents include two aspects: cytotoxicity and corrosiveness to probes:

The reaction integral of coupling agent to skin irritation is 0, and the allergic test score is 0, which is non-irritating; At normal temperature and high temperature, the pH value of medical ultrasonic coupling agent can always remain stable and neutral, so it is non-corrosive to ultrasonic probe and human skin.

From the content of the above article, we can find that coupling agent is a kind of hydrogel material widely used in medical examination summary, so its function is actually very extensive, not only suitable for B-ultrasound, but also suitable for quite a few examination items. The most important thing is that the coupling agent has no side effects at all and is safe to use.
