Description

technical field [0001] The invention relates to a medical ultrasonic coupling agent, in particular to a medical ultrasonic coupling agent with low sound attenuation characteristics. Background technique [0002] In order to strengthen the coupling between the ultrasonic probe and human skin, medical ultrasonic couplant has been widely used in ultrasonic testing. The use of ultrasonic coupling agent can isolate the air between the ultrasonic probe and the inspected part of the human body, improve the transmission efficiency of sound waves, and improve the detection effect. [0003] Because ultrasonic probes are expensive, one ultrasonic probe is usually used to detect a large number of people during ultrasonic testing, which can easily lead to the spread of germs during the testing process. Therefore, it is usually required that the ultrasonic coupling agent should have a sterilizing effect. In addition, in order to further improve the detection effect, the requirements for...
