Every ultrasound patient has undergone a procedure in which the doctor squeezes a clear jelly onto the site before the examination, and then hands the patient a tissue to wipe off the jelly when the examination is complete. For this sticky, not easy to wipe off the goo, you will have the following questions.

First, what is medical coupler? Medical coupler is a kind of medical product composed of water-based polymer gel for ultrasonic examination and is an indispensable medium in ultrasonic diagnostic examination. Medical couplings are divided into non-sterile type and sterile type. Non-sterile couplings are mainly used for ultrasound diagnostic and therapeutic procedures on intact skin. Aseptic coupler is used for intraoperative ultrasound, puncture biopsy and other ultrasonic diagnosis and treatment on wounds and intact skin.

Second, what is the role of medical coupler? 1, the exclusion of air ultrasonic conduction in the air will be attenuated by reflection, which has great interference with ultrasonic inspection. A layer of medical coupler is applied to the examination site, which can eliminate the air between the probe and the skin, so that the ultrasonic examination can be carried out smoothly. 2, improve the image quality medical coupler can reduce the resistance between the probe and the skin, using this "transition" effect of medical coupler, reduce the transmission resistance, reduce the reflection loss of ultrasonic energy, you can get a clearer image, thereby improving the accuracy of ultrasonic examination. 3, the medical coupler also plays a "lubricating" role, reducing the friction between the probe surface and the skin, so that the probe can slide flexibly for exploration, improve the patient's inspection comfort, and the inspection process is smoother.

In the early stage, ultrasonic coupler mainly used mineral oil (including petroleum jelly, butter), vegetable oil, silicone oil, etc., whose acoustic characteristics were poor, it was difficult to obtain high-quality ultrasonic images, and it was easy to stimulate the skin, damage the probe, dirty clothes, not easy to clean and other shortcomings. 

 With the development of ultrasonic medical, medical ultrasonic coupling agent has been in progress, Carbomer 960, carbomer 970 as excipients are applied extensively, proving efficient rheology modification and thickening.

We, Anhui Newman fine chemicals Co., ltd, as the leading manufacturer of carbomer products, our carbomer include personal care grade carbomer such as traditional carbomer 960,970,990, 981etc. Also improved carbomer with INCI name Acrylates/C10-30 Alkyl Acrylate Crosspolymer , such as carbomer 20, 21,2020, 1342, 1382 etc., have good thickening and clarity performance in hydroalcoholic gel. And they are refreshing , not sticky when being suitable for hand sanitizer gels.

 Newman carbomer products are popular and applied in pharmaceutical products as rheology modifiers, tablet binders, suspension stabilizers, extended-release polymers, mucoadhesive aids, and bioavailability enhancers, NM-Carbomer products are well known for their versatility and ease of use as pharmaceutical excipients.    Especially, Carbomer 934P, carbomer 974P, 2020G, 971P, carbomer 970G have been used extensively in the health field as excipient, such as  in ultrasonic gels , here is features,

1) Ideal Aesthetic and Sensory Qualities – increase patient compliance through low-irritation, aesthetically pleasing formulations with optimal feeling.

2)      Efficient Rheology Modification and thickening.

3)    Suitable viscosity, non-greasy, not easy to dry, good lubrication performance.
