Problems solved by technology

[0002] When medical personnel perform wound debridement and disinfection on patients, they often use traditional methods to directly wash and disinfect the patient's wound. Due to the complexity of the external environment, it is easy to cause cross-infection in the affected part of the patient, which is not conducive to the recovery of the patient's wound;
[0003] Existing studies have shown that using the cavitation effect of ultrasonic waves to flush wounds with water flow loaded with ultrasonic waves can effectively eliminate wound bacteria without causing serious damage to wounds. Therefore, there are already some medical ultrasonic waves in the prior art. cleaning machine, but the existing ultrasonic cleaning machine is not perfect enough, and has some shortcomings, such as: the connection structure between the horn and the shell is unreasonable, resulting in low electric / acoustic conversion efficiency, resulting in excessive heat generation, easy to burn tissue, A cooling mechanism needs to be installed on the horn
In addition, when performing debridement treatment at present, the finished product or pre-configured debridement solution is usually selected according to the actual situation of the patient for debridement, but the operation of the existing debridement machine to replace the debridement solution is not convenient enough, and it is impossible to use it according to the actual situation. Automatically configure debridement solution with appropriate ingredients on the spot
