Medical coupler is a medical product composed of a new generation of water-based polymer gels. Its PH value is neutral, non-toxic and harmless to the human body, not easy to dry, not easy to rancid, ultrasound imaging clear, suitable viscosity, no greasy, probe easy to slide, can moisturize the skin, eliminate the skin surface air, good lubrication performance, easy to expand; No corrosion and damage to the ultrasonic probe; Ultrasonic couplers with sterilization and disinfection functions have emerged in the market. Compared with the traditional common couplers, they are more strict for the production environment and more widely applicable.

Characteristics
PH value is neutral, non-toxic, tasteless, no irritation, no skin and clothing, no irritation to the skin, no allergic reaction, and easy to erase, with good thixotropy and no flow, easy to operate. Good stability, not affected by climate change.
Role of
Can be used in A type, B type, M type ultrasonic diagnostic instrument, Doppler blood flow meter, suitable for obstetrics and gynecology, digestive system, urinary system, nervous system, neonatal, thyroid and breast examination, can be coupled with ultrasound probe, improve the clarity of display, excellent effect; It is not necessary to repeat the application, which is helpful to save the time of diagnosis.
Application
Because the frequency of medical ultrasound is 2.5-5M, it cannot be conducted in air. If there is air in the probe and the skin, the ultrasound will return as soon as it meets the air, and it will not enter the body and play a role in the examination. The air between the probe and the skin can be eliminated by first applying a coupler to the skin.
First, the concept of ultrasonic coupler
During ultrasound examination, the air between the probe and the patient's skin will prevent the ultrasonic wave from passing into the body. In order to obtain high-quality and clear images, it is necessary to use liquid conduction medium to connect the probe to the patient's body surface, which is commonly used ultrasound coupler.
Second, the reason for the use of ultrasonic coupler
The purpose of using ultrasonic coupler is first to fill the small gaps between the contact surfaces, so that the trace air between these gaps does not affect the penetration of ultrasound; Secondly, the acoustic impedance difference between the probe and the skin is reduced by the "transition" effect of the coupler, so as to reduce the reflection loss of ultrasonic energy at this interface. In addition, it also plays a "lubricating" role, reducing the friction between the probe surface and the skin, so that the probe can slide flexibly.
Third, the influence of ultrasonic coupler on the image
The quality of the coupler is closely related to the quality of the obtained sonograms. Poor quality couplers can cause energy loss, resolution reduction, image blurring, and even skin irritation and damage to the probe.
