The core function of ultrasonic gel is to act as a "bridge" for sound wave transmission. It effectively eliminates air gaps between the ultrasound probe and the skin, improving image quality and enhancing examination comfort.
Main Functions and Benefits:
Improving Ultrasonic Imaging Quality: Air strongly reflects ultrasound waves, causing signal attenuation and image blurring. The gel fills tiny depressions in the skin, reducing sound wave reflection and allowing ultrasound waves to penetrate the body more smoothly, resulting in clear and accurate images, aiding doctors in precise diagnosis.
Enhancing Probe Smoothness: The gel acts as a lubricant, allowing the probe to move more smoothly across the skin, facilitating multi-angle scanning by doctors, while reducing discomfort from friction and improving patient experience.
Protecting Skin from Device Contact: Preventing direct friction between the probe and the skin reduces the risk of irritation or damage, especially important for sensitive areas (such as the face and abdomen).
Safe, harmless, and easy to clean. Medical ultrasound coupling agents are mostly composed of water-soluble polymers, glycerin, propylene glycol, etc. They are non-toxic, non-irritating, and unlikely to cause allergies. They can be removed by wiping with a tissue or rinsing with water after the examination.
