A cooling patch for microwave radiofrequency ablation body surface

Abstract

The present invention proposes a body surface cooling patch for microwave radiofrequency ablation, which includes a transparent dressing patch, an adhesive layer is provided on the back of the transparent dressing patch, and a passage sheet is provided on the side of the transparent dressing patch facing away from the adhesive layer. Shaped material is rolled into a storage tube with a cylindrical structure, and the lower end of the storage tube is heat-sealed and docked with the transparent dressing patch; the storage tube includes two sections of an inner tube and an outer tube that are concentrically arranged with each other, and the inner tube The lower end is heat-sealed butted with the lower end of the outer cylinder and connected to the transparent dressing patch, the upper end of the inner cylinder is heat-sealed butted with the upper end of the outer cylinder, and several rims are provided between the inner cylinder wall and the inner cylinder wall of the outer cylinder. The tubes are evenly distributed in the circumferential direction, and are heat-sealed along the axial direction of the containing tube, so that the outer wall of the inner tube and the inner wall of the outer tube are bonded together; there is also an air-filling port between the upper end of the inner tube and the upper end of the outer tube , a one-way diaphragm is arranged in the inflation port. The invention has the advantages of effectively cooling the skin temperature during microwave radiofrequency ablation at the superficial position and avoiding skin burns and ulcers.

Description

technical field [0001] The invention relates to the field of radiofrequency ablation, in particular to a body surface cooling patch for microwave radiofrequency ablation. Background technique [0002] Microwave curing and radiofrequency ablation are emerging technologies in recent years. Radiofrequency ablation uses a radiofrequency needle to puncture into the tumor and emit radiofrequency waves. The radiofrequency waves oscillate violently in the tumor to generate high temperature and necrosis of tumor cells. To achieve the purpose of treatment, the treatment principle of microwave curing is similar to that of radiofrequency ablation, but the skin will be burned in the superficial position, forming a wound or ulcer, so it is necessary to design a device that reduces burns and avoids ulcers, thereby reducing the number of patients. pain. Contents of the invention [0003] Based on the above problems, the object of the present invention is to provide a microwave radiofrequ...
