The invention discloses an ultrasonic
coupling agent and application of the ultrasonic
coupling agent in ultrasonic inspection or auxiliary treatment of clinical cavity canals, mucous membranes, non-
intact skin and the like in hospital. The ultrasonic
coupling agent consists of the following raw materials: safe and nontoxic silver ions or nanometer silver serving as a
disinfectant, and bio-compatibility macromolecular materials serving as a
viscosity regulator, an anti-discoloration agent, an anti-precipitant agent, and an anti-
stimulant agent. The ultrasonic coupling agent meets the requirements on ultrasonic impedance and no
corrosion, has the characteristics of disinfection, sterilization, safety, nontoxicity, no stimulation and the like, can effectively avoid
cross infection in ultrasonic clinics, can be suitable for detecting the cavity canals, the mucous membranes and the non-
intact skin, and has high medical
clinical value. The ultrasonic coupling agent has a simple preparation method, and low cost of raw materials.
