Sealing components, focused ultrasound treatment system and operation method, semi-dry acoustic coupling apparatus

A focused ultrasound treatment system, comprising a medium container with two ends opened, a waterproof adhesive ring, an ultrasound emission device, a gas pressure increase/decrease component, a coupling fluid increase/decrease component, and a pressure control module,

• wherein the ultrasound emission device comprises a shell and an ultrasound emission portion, and the shell and the ultrasound emission portion enclose an inflatable confined space;
• a first connecting surface of the waterproof adhesive ring is configured to attach to a skin of a patient;
• a second connecting surface of the waterproof adhesive ring is bonded with a first end of the medium container with two ends opened, and a second end of the medium container is tightly connected with the shell of the ultrasound emission device;
• a gas pressure sensor configured to detect a gas pressure at an inner side of the ultrasound emission portion is provided in the confined space, and a hydraulic pressure sensor configured to detect a pressure at an outer side of the ultrasound emission portion is provided in a coupling fluid in the medium container;
• the gas pressure increase/decrease component and the coupling fluid increase/decrease component are connected with the pressure control module;
• and
• the pressure control module is configured to receive pressure data of the gas pressure sensor and the hydraulic pressure sensor and control the gas pressure increase/decrease component and the coupling fluid increase/decrease component to increase/decrease pressures at inner and outer sides of the ultrasound emission portion, respectively.
