Technical Field

Background
The medical coupling agent is a medical product consisting of aqueous polymer gel, has a neutral pH value, is non-toxic and harmless to a human body, is not easy to dry and rancid, has clear ultrasonic imaging, high viscosity and no oiliness, can wet the skin by easily sliding a probe, eliminates air on the surface of the skin, and has good lubricating property and easy unfolding. During ultrasonic detection, air between the probe and the skin of a patient can prevent ultrasonic waves from being transmitted into the human body, and an ultrasonic coupling agent is required to be used for connecting the probe and the body surface of the patient in order to obtain a high-quality clear image. The purpose of using the ultrasonic couplant is to fill micro gaps between contact surfaces firstly, so that trace air between the gaps does not influence the penetration of the ultrasonic waves; secondly, the acoustic impedance difference between the probe and the skin is reduced through the transition effect of the coupling agent, so that the reflection loss of the ultrasonic energy at the interface is reduced. In addition, the probe also has the function of lubrication, reduces the friction between the probe surface and the skin, and enables the probe to be flexibly probed in a sliding way.
In the clinical use process, the coupling agent is filled in a special bottle, and medical workers need to squeeze the coupling agent in the bottle onto an ultrasonic probe by hands, because the viscosity of the coupling agent is very high, the squeezing is very laborious. Medical care workers may need to repeatedly squeeze the couplant up to several hundred times during work hours, the whole process is mechanical and labor-consuming, the workload is increased invisibly, the working efficiency is reduced, and meanwhile, the hand discomfort is caused. The ordinary liquid pump with too high viscosity is difficult to pump out the couplant, and no auxiliary equipment capable of solving the problem of extruding and coating the couplant exists in the market at present.
