Coupled fluid supply device used for high-intensity focused ultrasound therapy system

Abstract

The invention belongs to the medical apparatus technical field and provides a coupled fluid supply device used for a high-intensity focused ultrasound therapy system. The objective of the invention is to solve the problem of being difficult to obtain an ideal propagation medium in a preparation process of de-gassed water in the prior art. The coupled fluid supply device includes a coupled fluid preparation device used for preparing a mixed liquid formed by medical alcohol and polyvinyl pyrrolidone, a water circulation degassing device which is communicated with the coupled fluid preparation device and prepares the de-gassed water by utilizing a vacuumizing method, and a transfer device which is communicated with the water circulation degassing device and transfers a coupled fluid to a high-intensity focused ultrasound therapy head, wherein the coupled fluid is formed through mixing the mixed liquid and the de-gassed water. The fully-stirred mixed liquid of the medical alcohol and the polyvinyl pyrrolidone is added in the preparation process of the de-gassed water, and therefore, the mixed liquid can be fully mixed with the de-gassed water, and the coupled fluid which is transferred into the high-intensity focused ultrasound therapy head can have excellent propagation medium characteristics.

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...
