In fact, the sticky and cool liquid that doctors apply to patients before B-ultrasound is called medical ultrasound coupling agent. Suitable for all kinds of black-and-white or color ultrasonic diagnosis and treatment operations, mainly used as the transmission medium between the probe (or therapeutic head) and the skin, eliminating the air on the surface between the instrument probe and the skin, displaying the reflected image of the examination organ, making the B-ultrasound examination smoother and the probe clearer; At the same time, it has good lubricity and moisturizing function, reducing the friction between skin and probe; It usually takes trichlorohydroxydiphenyl ether as the main active ingredient, which is a disinfection gel, which can kill intestinal pathogenic bacteria, purulent cocci and pathogenic yeasts, thus preventing cross-infection when different patients touch the probe during examination, and finally avoiding some infectious diseases; In addition, the coupling agent has no corrosion or damage to the ultrasonic probe.
With the continuous development of ultrasonic medicine, ultrasonic diagnostic instruments are rapidly popularized, and ultrasonic examination is more and more widely used in clinic. So after the examination, the doctor will give you some paper, and you can use it to wipe off the sticky coupling agent. Medical coupling agent is a medical product composed of a new generation of aqueous polymer gel. Its PH value is neutral, non-toxic and harmless, so don't worry.
