Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment and relates to a voltage stabilization control system suitable for a transcranial magnetic wave knife. Background Art

[0002] In order to achieve thermal ablation of the skull, a helmet-shaped probe matrix needs to be put on the patient's head, and the water bag space between the probe and the patient needs to be filled with decarbonated water. The transcranial water cooling system needs to ensure the pressure of the decarbonated water in the helmet so that the decarbonated water can stably exist between the patient's head and the helmet. At present, there is no independently developed transcranial magnetic wave knife product in China, so there is a lack of a water cooling circulation system that can be adapted to it. Combined with the working requirements of transcranial magnetic wave knife products, the water cooling circulation system is required to maintain a constant water pressure in the water bag under conditions of a higher flow rate. Therefore, the system has a higher precision control over the water flow rate of the supply and return pipelines. However, most of the existing technologies are only applicable to pressure container systems, and have lower requirements for the control accuracy of flow and pressure, and are not applicable to transcranial magnetic wave knife products. Utility Model Content

[0043] The above embodiments may be implemented individually or in combination of two or more.

[0044] The above implementation is described in more detail below in conjunction with specific examples.

[0045] Embodiment 1:

[0046] In order to effectively control the pressure of the water bag 4 and ensure the safety of the magnetic wave knife treatment, this embodiment provides a voltage stabilization control system suitable for transcranial magnetic wave knife. The structure of the control system can be seen in Figure 1 As shown, including:

[0047] Water bladder 4;

[0048] A driving device 2, comprising at least one water supply pump head and at least one water return pump head connected in parallel, wherein the water supply pump head and the water return pump head are connected to the water bag 4 via a water supply pipeline 8 and a water return pipeline 9 respectively;

[0049] And a control device 3, which is used to control the on-off of the water supply pipeline 8 and the return water pipeline 9.

[0050] Specifically, the control device 3 may adopt a multi-way valve commonly used in the art to realize the connection and disconnection between the water supply pipeline 8, the water return pipeline 9, and the water supply pipeline 8 and the water return pipeline 9 according to different working modes.

[0051] All water supply pump heads and return water pump heads are also connected to each other through bypass pipelines to achieve mutual communication between the two. An independently controlled valve is also provided on the bypass pipeline connecting the return water pump head and the water supply pump head.

[0052] Please see again Figure 1 As shown, the voltage stabilization control system further comprises a water storage device 1, the water inlet and the water outlet of the water storage device 1 are respectively connected to the return pump head and the water supply pump head. The entire water storage device 1 can adopt a commonly used water storage device in the art, such as a water storage tank.

[0053] Please see again Figure 1 As shown, the water bag 4 is also provided with a pressure stabilizing device, which includes a pressure collecting mechanism 5 for collecting the pressure value in the water bag 4, and a pressure stabilizing mechanism 6 for assisting in stabilizing the pressure in the water bag 4. More specifically, the water bag 4 is provided with a pressure stabilizing mechanism 6 (specifically, a water blocking filter can be used) to ensure that the water in the water bag 4 will not overflow, and at the same time, it can stabilize the pressure in the water bag 4 in the drainage mode; the water bag 4 is provided with a pressure sensor as the pressure collecting mechanism 5. If the pressure in the water bag 4 exceeds the set upper and lower limits, the system will automatically start the injection and drainage mode to balance the pressure between the water bag 4 and the atmosphere. That is, when the pressure sensor detects that the internal pressure of the water bag 4 exceeds the set value range, the water outlet of the water bag 4 is connected to a return water pump head, the water inlet of the water bag 4 is disconnected from the water supply pump head, and the remaining return water pump heads are still connected to the water supply pump head to form a pressure reduction circulation pipeline.

[0054] Please see again Figure 1 As shown, a flow sensor 7 is also provided on the water supply pipeline 8 between the water supply pump head and the water bag 4 .

[0055] The driving device 2 is a peristaltic pump. By utilizing the characteristic that the peristaltic pump can be connected to the pump head in parallel, the flow balance performance of the water supply and return pipes is improved, the pressure of the water bag 4 is effectively controlled, and the safety of the magnetic wave knife treatment is ensured.

[0056] The water supply pump head is provided with one; the water return pump head is provided with two. The whole system may include a water supply pipeline 8 and two water return pipelines 9, realizing the functions of water injection, circulation, drainage, etc. of the transcranial magnetic wave knife water circulation system, greatly simplifying the control logic and reducing the interference of the control module.

[0057] In specific operation, the voltage stabilization control system of this embodiment can have the following multiple working modes through pipeline switching, and the dotted lines in the following figures indicate that the pipeline is disconnected at this point:

[0058] Water injection / circulation mode, such as Figure 2 As shown, the driving device 2 is in a normally open state. When the water injection / circulation mode is turned on, the control device 3 switches the pipelines so that the water storage device 1 and the water bag 4 are connected through the water supply pipeline 8 and the return pipeline 9 to form a circulation. At this time, the pure water in the water storage device 1 is driven by the water supply pump head in the driving device 2 and is sucked into the water bag 4 through the water supply pipeline 8, and the air in the water bag 4 is sucked into the water storage device 1 through the return pipeline 9 by the return pump head;

[0059] Treatment modalities, such as Figure 3 As shown, in the circulation mode, when the transcranial magnetic wave knife enters the treatment mode, the control device 3 disconnects the water storage device 1 and the water bag 4 through pipeline switching, and the water circulation in the water bag 4 stops. At this time, the water supply pipeline 8 can be directly connected to a return pipeline 9, so that the water in the water storage device 1 is directly circulated from the water supply pipeline 8 and the return pipeline 9;

[0060] Drainage mode, such as Figure 4 As shown, in the circulation mode, when the drainage mode is turned on, the control device 3 connects one of the return pipes 9 to the water outlet of the water bag 4. At this time, the water in the water bag 4 is pumped back by the return pump head through this return pipe 9 and flows into the water storage device 1. The outside air enters the water bag 4 through the pressure stabilizing mechanism 6 to balance the pressure in the water bag 4.

[0061] Embodiment 2:

[0062] Based on the voltage stabilization control system of Example 1, this embodiment provides a transcranial magnetic wave knife for treating transcranial diseases, including a body and a voltage stabilization control system suitable for transcranial magnetic wave knife as in Example 1. At this time, the water bag 4 is located in the treatment helmet in the body of the transcranial magnetic wave knife product.

[0063] Specifically, the machine body includes but is not limited to a treatment bed body, a transformer box, a water cooling system integration box, etc., and the water bag voltage stabilization control system is arranged in the machine body.
