Because the majority of patients to check parts of the skin in good condition and without damage, healthy intact skin itself as a barrier to a stop outside the germ attack, so for these patients, clinical ultrasound diagnosis or treatment is not required for skin disinfection, in principle, the use of sterile type coupling agent, is ultrasound doctors use at ordinary times, normal coupling agent. However, with the increasing attention and attention to the hygienic and cross-infection problems in clinical examination, the demand for special medical ultrasonic couplers (asepsis, sterilization, etc.) is also increasing. The Canadian Department of Health, for example, explicitly requires: "Aseptic gels must be used for all invasive procedures involving device penetration through tissue (e.g., needle aspiration, needle localization, and tissue biopsy), in sterile environments, and in infants with defective skin and in the infant care unit. Sterile gels or bacteriostatic gels should als...

Since medical ultrasound was used to detect injuries in the early stage, early use of mineral oil (including petroleum jelly, butter), vegetable oil, silicone oil, etc. as an  ultrasound gel . However, due to its poor acoustic characteristics, it is difficult to obtain high-quality ultrasound images, and it is easy to irritate the skin, damage the probe, dirty clothes, and not easy to clean, etc., which is gradually not accepted by doctors and patients. With the development of modern ultrasound medicine, there is an urgent need for a safe and effective  ultrasound transmission gel . In the end, researchers first chose polymer gel preparations. As early as the early 1980s, when China began to bleed ultrasonic instruments, the medical ultrasound transmission gel that followed the equipment, its main component was carbomer resin, and added neutralizers, wetting agents, preservatives, colorants, etc. Formulated. Those who have studied chemistry should know that carbomer resin is a...

Ultrasound examination is currently the most widely used clinical screening or examination method. When the patient comes to the ultrasound department of the hospital for the ultrasound examination, the examination site is always coated with a light blue or transparent gel. For the sonographer, this gel is an important tool for ultrasound examination to be carried out smoothly, it is really ordinary, but to patients is quite strange. Next, the  instant hand sanitizer gel manufacturer  introduces you to ultrasonic gel. First, let's understand why ultrasound is used for this gel. Those who have studied physics should know that when ultrasonic waves hit the interface of two different media, reflections will occur, resulting in less energy for the ultrasonic waves entering the other medium. The degree of reflection of ultrasonic waves is related to a certain index of the two media. This index is the acoustic impedance. Acoustic impedance indicates the ability of a medium to h...

I believe that everyone who has done an ultrasound examination will have a question or complaint. Why does the doctor apply a cool, damp liquid to the body every time an ultrasound examination is done? What is this thing? It’s all over my body. Can I not use this when doing ultrasound? This sticky thing is medical disinfection  ultrasound transmission gel . Medical ultrasound transmission gel is a medical product composed of a new generation of the aqueous polymer gel. Its PH value is neutral, non-toxic and harmless to the human body, not easy to dry, not easy to rancidity, clear ultrasonic imaging, suitable viscosity, non-greasy, the probe is easy to slide, can moisturize the skin, eliminate the skin surface air, lubricating Good, easy to deploy; no corrosion and damage to the ultrasonic probe. Ultrasound examination is inseparable from couplant. 1. Because the medical ultrasonic frequency is 2.5-5M, it cannot be conducted in the air. When there is air in the probe and the skin, t...
