Problems solved by technology

However, during the treatment process, the medium water is in contact with the patient's body surface, and the water quality is polluted and cannot be recycled.
In order to reduce the heat generated by patients during the treatment process, the water needs to be changed frequently, resulting in increased water consumption and huge equipment

Embodiment Construction

[0022] Use the following image 3 , Figure 4 with Figure 5 , the permeable membrane type coupling device of the present invention will be described. image 3 It is a schematic diagram of using the permeable membrane coupling device of the present invention for treatment, such as image 3 As shown, the human body is lying prone on the treatment bed (not shown in the figure), and is in contact with the permeable membrane coupling device of the present invention. The ultrasonic waves emitted by the ultrasonic treatment device 10 enter the human body through the medium liquid and converge on the treatment target area 11. The temperature of the focus cells at the treatment target area 11 is increased, thereby killing the focus cells.

[0023] Figure 4 It is a schematic diagram of the structural principle of the permeable membrane coupling device of the present invention, including a one-way permeable elastic membrane 1, a pressure detection device 4, a patient's body surface...

Abstract

This invention provides a high strength focusing ultrasonic curing penetrating membrane type coupling device. It has water sac used to fill couplant liquor contacted with patient body surface, and osmotic membrane set on the sac that can let dielectric liquid one way penetrate. When the membrane served as boundary, osmotic medium liquor area is formed at up part and closed medium liquor area is formed at lower part. It also has pressure detecting device set in osmotic medium liquor area or semi isolated osmotic medium liquor. It also has medium liquor adjusting unit to supply and discharge medium liquor to the semi isolated osmotic medium liquor area, and it receive liquor pressure detecting value output by pressure detecting device. Then medium liquor adjusting unit is controlled according to the value to control liquor pressure of semi isolated osmotic medium liquor and medium liquor height of osmotic medium liquor.

Description

technical field [0001] The invention relates to a permeable membrane coupling device for high-intensity focused ultrasound therapy, which can transmit ultrasonic waves to the patient's body through the permeated medium liquid for high-intensity focused ultrasound treatment. Background technique [0002] Medical research has found that the heat resistance of tumor cells is worse than that of normal cells. In a temperature environment above 42.5°C, tumor cells die within 30 minutes, while normal cells are slightly damaged and reversible. Based on this characteristic of tumor cells, the high-intensity focused ultrasound tumor therapy system uses ultrasound as the energy source, uses its penetrability and focusability, and couples the ultrasound with low average sound intensity emitted by the probe through the medium and passes through the skin. Enter the human tumor tissue, focus or converge to a spatial point to form an average sound intensity of 1000W / cm 2 The above focal re...
