Embodiment 1

[0043] This embodiment provides an ultrasonic medium liquid level control device, such as figure 1 As shown, it includes a negative pressure chamber 1 capable of maintaining negative pressure and a pressure control component 2, wherein the bottom of the negative pressure chamber 1 is provided with a first opening 11, and the first opening 11 is used for supplying at least part of the ultrasonic transducer 3 The sound generating surface enters and exits the negative pressure chamber 1; the negative pressure chamber 1 has a side wall, and part of the side wall is used to contact the human body, the side wall is the first side wall 10, and the first side wall 10 is made of flexible material; the pressure control The component 2 communicates with the top 17 of the negative pressure chamber 1 for controlling the air pressure in the negative pressure chamber 1 .

[0044] When the ultrasonic medium liquid level control device of this embodiment is used, the first opening 11 of the lo...

Embodiment 2

[0046] This embodiment provides an ultrasonic medium liquid level control device, such as figure 2As shown, it includes a negative pressure chamber 1 capable of maintaining negative pressure and a pressure control component 2, wherein the bottom of the negative pressure chamber 1 is provided with a first opening 11, and the first opening 11 is used for supplying at least part of the ultrasonic transducer 3 The sound generating surface enters and exits the negative pressure chamber 1; the negative pressure chamber 1 has side walls, and part of the side walls is used to contact the human body, the side wall is the first side wall 10, the first side wall 10 is made of flexible materials, and the second The side wall 10 is folded in a wave shape; the pressure control component 2 communicates with the top 17 of the negative pressure chamber 1 for controlling the air pressure in the negative pressure chamber 1 .

[0047] In this embodiment, the first side wall 10 is made of wave-fo...

Embodiment 3

[0056] This embodiment provides an ultrasonic medium liquid level control device, which has a structure similar to that of the ultrasonic medium liquid level control device in Embodiment 2. The difference between it and Embodiment 2 is that, as Figure 5-8 As shown, the first side wall 10 includes an inner wall 12 and an outer wall 13. Both the inner wall 12 and the outer wall 13 are made of flexible materials. A closed space can be formed between the inner wall 12 and the outer wall 13. At least part of the inner wall 12 and the outer wall 13 are provided with Closable channel 16 for injecting ultrasound medium 4 into the enclosed space.

[0057] In this embodiment, the first side wall 10 is made of thinner inner and outer layers of flexible material, for example, it can be made of sound-permeable flexible plastic, wherein a cavity can be formed between the inner wall 12 and the outer wall 13, and the For filling the ultrasonic medium 4. Since the plastic itself is lighter a...

Abstract

The invention provides an ultrasonic medium liquid level control device and a focused ultrasonic treatment device, belongs to the technical field of high-intensity focused ultrasound, and can solve the problem that an existing high-intensity focused ultrasound has a large demand for liquid conduction medium and failure to control a height of the liquid conduction medium. In the ultrasonic medium liquid level control device, an first opening of a negative pressure chamber extends into a container in which an ultrasonic acoustic channel generated by an ultrasonic transducer is located; the negative pressure chamber is controlled to maintain a negative pressure, thereby pumping the ultrasonic medium in the container into the negative pressure chamber to inundate the top of a sound surface, which is equivalent to satisfying immersion of the top sound surface of the ultrasonic transducer in the medium, resulting in complete conduction of emitted ultrasonic wave in the medium and reducing requirement for the height of the liquid level height in the container, thereby avoiding a negative effects such as discomfort on a patients due to high liquid level. Meanwhile a first side wall of thenegative pressure chamber in contact with a human body is composed of a flexible material and not uncomfortable to the human body.

Description

technical field [0001] The invention belongs to the technical field of high-intensity focused ultrasound, and in particular relates to an ultrasonic medium liquid level control device and focused ultrasound treatment equipment. Background technique [0002] High Intensity Focused Ultrasound (HIFU) technology can form high-intensity and continuous ultrasonic energy on the lesion by focusing ultrasonic waves, thereby producing transient high-temperature effects, cavitation effects, mechanical effects, and sonochemical effects, making cell membranes 1. The nuclear membrane ruptures, coagulates the protein, selectively causes coagulation necrosis of the lesion tissue, and makes the lesion lose the ability to proliferate, infiltrate and metastasize. As a new technology for the treatment of tumors and other diseases, high-intensity focused ultrasound therapy has been clinically recognized and is widely used in the treatment of various tumors and non-tumor diseases. [0003] When ...
