Coupling fluid supply equipment for high-intensity focused ultrasound therapy systems

Abstract

The invention is applicable to the technical field of medical devices, provides a coupling liquid supply device for a high-intensity focused ultrasound treatment system, and aims to solve the problem in the prior art that it is difficult to obtain an ideal propagation medium during the preparation of degassed water. The coupling liquid supply equipment includes a coupling liquid configuration device for preparing a mixed liquid formed of medical alcohol and polyvinylpyrrolidone, a water circulation degassing device connected with the coupling liquid configuration device and using a vacuum method to prepare degassed water, and a water circulation degassing device connected with the water circulation degassing device. The gas device communicates and transmits the coupling liquid formed by the fusion of the mixed liquid and the degassed water to the transmission device of the high-intensity focused ultrasound treatment head. In the process of preparing degassed water, add a mixed solution of medical alcohol and polyvinylpyrrolidone that has been fully stirred to fully integrate the mixed solution with the degassed water, so as to ensure that the coupling liquid transmitted to the high-intensity focused ultrasound treatment head has a good spread media properties.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a coupling liquid supply device for a high-intensity focused ultrasound treatment system. Background technique [0002] At present, the application of high-intensity focused ultrasound therapy is becoming more and more extensive. The high-intensity focused ultrasound therapy technology refers to a treatment technology that mainly uses a high-intensity focused ultrasound (High-Intensity Focused Ultrasound, HIFU) treatment system. The high-intensity focused ultrasound therapy system is composed of power source, treatment control, positioning and real-time evaluation, motion control and other parts. Instantaneous coagulation necrosis, no significant damage to tissues outside the focal area, and coagulation necrosis can eventually be gradually absorbed or scarred. This new technology of local treatment of tumors is also called thermal "resection", which is mainly...
