超声治疗机是利用超声换能器即治疗头将电能转换成机械能的一种医用仪器。它主要由电源、控制部分及输出部分等组成。使用时将治疗头置于被治疗部分的皮肤表面，通过涂以耦合剂的皮肤，将超声能量传入人 体内。通过超 声能量作用于 生物体，利用 超声对生物体 的物理及化学 作 Ultrasound therapy machine is the use of ultrasound transducer that is the first treatment of electrical energy into mechanical energy of a medical instrument. It is mainly composed of power supply, control part and output part. When used, the therapeutic head is placed on the skin surface of the treated part, and the ultrasonic energy is transmitted into the human body through the skin coated with the coupling agent. By ultrasound energy on the organism, the use of ultrasound on the physical and chemical organisms
