Many people have had such a similar experience, is to go to the hospital to do ultrasound before the ultrasound doctor to his body coated with a layer of sticky and cool liquid, and then use the instrument probe to do the examination. Many people have questions, what is this liquid? Do you need to wash it off immediately after the ultrasound?
Medical ultrasound coupling agent composition and role
In fact, the doctor to do ultrasound to the patient body coated with a layer of sticky, cool liquid, medicine is called medical ultrasound coupling agent, the acoustic impedance and the human body's soft tissues are similar. Apply to a variety of various types of black and white or color ultrasound diagnostic and therapeutic operations, used as a probe (or treatment head) and the skin between the transmission medium, and has an emollient function. Usually a disinfectant gel with trichlorohydroxydiphenyl ether as the main active ingredient, the content of trichlorohydroxydiphenyl ether is 0.29%-0.32%. It can kill intestinal pathogenic bacteria, purulent cocci, and pathogenic yeast.
Ultrasonic coupling agent is used to apply on the skin of the test site to eliminate the air between the instrument probe and the skin, and to display the reflected image of the examined organ. With the continuous development of ultrasound medicine, diagnostic ultrasound instruments are rapidly gaining popularity. Ultrasonography is more and more widely used in clinical practice. Accordingly, as an essential supporting supplies in ultrasound examination, medical ultrasound coupler is also used in large quantities in the clinic. This medical ultrasound coupler can reduce the friction between the skin and the probe, thus making the ultrasound examination smoother and allowing the probe to be more clearly examined. Moreover, the medical ultrasound coupling agent can play a good role in disinfection and antibacterial effect, which can prevent different patients from contacting the probe when the formation of cross-infection, and ultimately lead to some infectious diseases.
Is medical ultrasound coupling agent harmful to human body?
Many people may still worry about whether this liquid will be harmful to the body, in fact, do not worry, this medical ultrasound coupling agent belongs to the water-soluble liquid, there is no harm to the body, which usually contains antiseptic ingredients, instead of protecting the body skin from infection. The company's products and services are available in a wide range of colors and sizes, including: (1) a variety of colors, (2) a variety of colors, (3) a variety of colors, (4) a variety of colors, (5) a variety of colors, and (6) a variety of colors.
What are the characteristics of a good ultrasound coupling agent?
Good ultrasound coupling agent should have good acoustic performance, image clarity, resolution and other acoustic characteristics of the requirements, should also have a good safety, human safety, non-toxic, non-irritant, easy to coat, easy to remove, do not damage the instrument probe and other characteristics for the intervention of the ultrasound coupling agent should also have a good biocompatibility, in the body can be degraded and absorbed. Medical ultrasound coupling agent quality standards should be developed and strictly enforced. Strengthen the management of coupling agent production. Non-invasive coupling agent can be included in the management of medical aids, while the interventional coupling agent is appropriate to be classified as a drug management is more reasonable.
In short, to do ultrasound before the body coated with the layer of liquid is a medical ultrasound coupling agent, there is no harm to the human body, just sticky does make people feel uncomfortable, if the conditions allow the wash away of course better, if it is inconvenient to wash, with a warm towel or paper towel wipe can be said to be the Japanese ultrasound medical examination, ultrasound coupling agent is warm, after the heating process, to the medical examination of the person to wipe is warm wet paper towel, the coupling agent is warm, after the heating process, to the medical examiner to wipe is also a warm, wet paper towel, to the medical examiner. is a warm wet paper towel, I hope that our domestic medical examination conditions can also have such a temperature, look forward to!
