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 probe matrix in the shape of a water bag needs to be placed on the patient's head. The space in the water bag 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 water bag so that the decarbonated water can stably exist between the patient's skull and the water bag. Currently, there are few cooling circulation systems with high flow rates for micro-pressure containers such as the above-mentioned water bags in China. Since the pressure-bearing capacity of micro-pressure containers is low or even incapable of bearing pressure, such systems have extremely high requirements for flow and pressure control. Most existing systems are used in pressure containers, and have low requirements for flow and pressure control accuracy. Systems used in micro-pressure containers such as water bags have relatively small flow requirements, which are insufficient to meet the cooling requirements of transcranial magnetic wave knife.

[0056] Please see again Figure 1 As shown in FIG. 1 , the pressure stabilizing device includes a pressure collecting mechanism 8 for collecting the pressure value in the water bag 5 and a pressure stabilizing mechanism 9 for assisting in stabilizing the internal pressure. The pressure collecting mechanism 8 is connected to the control device and is used to feed back the collected pressure signal to the control device. Here, by providing the pressure stabilizing mechanism 9 on the water bag 5, it can ensure that the water in the water bag 5 will not overflow, and at the same time, it can stabilize the internal pressure of the water bag 5 in the drainage mode.

[0057] The pressure collection mechanism 8 is a pressure sensor, which is used to monitor whether the micro-pressure water bag 5 is ruptured, and can control the system in time to ensure the safety of treatment; the pressure stabilizing mechanism 9 is a water-blocking filter that blocks liquid circulation and allows air to pass through.

[0058] The voltage stabilization control system also includes a water storage device 1, which is also connected to the water supply pipeline and the water return pipeline to form a circulation pipeline of "water storage device 1-water supply device 2-water bag 5-water outlet device 3". The entire water storage device 1 can adopt water storage equipment commonly used in the art, such as a water storage tank.

[0059] Please see again Figure 1 As shown, a pipeline switching module 10 connected in parallel with the water bag 5 is also provided between the water supply pipeline and the return pipeline, so as to realize the on-off between the water bag 5 and the water supply pipeline, the water bag 5 and the return pipeline, and the water supply pipeline and the return pipeline through the pipeline switching module 10.

[0060] The water supply pipeline and the return pipeline are respectively provided with independent flow sensors for monitoring the flow of the corresponding pipelines, which correspond to the first flow sensor 4 and the second flow sensor 11 respectively, and the flow sensors are also connected to the control device.

[0061] The control device includes a processor 6 and a frequency converter 7, and the processor 6 is connected to the frequency converter 7, and adjusts the flow of the water supply device 2 or the water outlet device 3 through the frequency converter 7.

[0062] 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:

When the pressure value in the water bag 5 is lower than the lower limit, the frequency converter 7 reduces the flow of the water outlet device 3, so that the pressure in the water bag 5 fluctuates within a safe pressure range;

[0064] Treatment modalities, such as Figure 3 As shown, in the circulation mode, when the treatment mode is turned on, the connection between the water bag 5 and the water storage device 1 is disconnected through the pipeline switching module 10, so that the water supply pipeline and the return pipeline bypass the water bag 5 and are directly connected through the bypass, and the water circulation in the water bag 5 is stopped;
