Description

Technical Field

[0001] The present invention relates to the technical field of medical cooling control, and in particular to a coil circulation cooling control system and method for a transcranial magnetic stimulator. Background Art

[0002] During the operation of the transcranial magnetic stimulator, the stimulation coil needs to continuously generate high-frequency magnetic field pulses. This process will cause the coil to generate a large amount of heat. If the heat cannot be dissipated in a timely and effective manner, the temperature of the coil will be too high, which will cause its working performance to decline, shorten its service life, and even threaten the patient's treatment safety. In order to overcome this technical problem, those skilled in the art are actively exploring. For example, the technical solution of Chinese Patent Publication No. CN117930916A proposes a cooling device for a magnetic stimulator and an intelligent temperature control system thereof, which can intelligently correct, optimize and regulate the cooling strategy of the magnetic stimulator coil. However, this solution still has shortcomings. The current cooling system of the transcranial magnetic stimulator generally has the problems of low cooling efficiency and poor control accuracy. It is impossible to implement dynamic adjustment according to the actual state of the coil and the coolant, and it is difficult to meet the cooling requirements of the transcranial magnetic stimulator under different working conditions. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a transcranial magnetic stimulator coil circulation cooling control system and method.

[0004] The technical solution adopted in the present invention is as follows: A transcranial magnetic stimulator coil circulation cooling control system includes a transcranial magnetic stimulator, and a temperature acquisition module, a feedback control module, a flow regulation module, a flow detection module, and a coolant cooling module arranged in the transcranial magnetic stimulator, wherein: The temperature acquisition module includes a temperature sensor I located at the head of the stimulation coil of the transcranial magnetic stimulator and a temperature sensor II located at the end of the coolant circulation pipeline. The temperature sensor I is used to detect the temperature value I of the stimulation coil after the magnetic field pulse is generated, and the temperature sensor II is used to detect the temperature value II of the coolant after cooling. When either the temperature value I or the temperature value II exceeds the threshold, the coolant cooling module is activated. A flow detection module includes a flow meter located on the coolant circulation pipeline, the flow meter is used to detect the flow value of the coolant in the coolant circulation pipeline; A flow regulating module includes a solenoid valve located on the coolant circulation pipeline, the solenoid valve is used to control the flow intensity of the coolant in the coolant circulation pipeline; The coolant cooling module includes a liquid cooling box, a coolant circulation pipeline, a cooling pump, and a cooling fan. The liquid cooling box is placed outside the shell of the transcranial magnetic stimulator. The cooling pump is connected to the liquid cooling box and the stimulation coil head through the coolant circulation pipeline, and is used to deliver coolant to the heating stimulation coil head. The cooling fan is placed in the liquid cooling box and is used to cool the returning coolant, increase the heat dissipation efficiency, and accelerate the gas flow rate at the liquid cooling box for rapid heat dissipation. The feedback control module includes an MCU controller. The input end of the MCU controller is respectively connected to the temperature acquisition module and the flow detection module for obtaining temperature and flow information; the output end of the MCU controller is respectively connected to the flow regulation module and the coolant cooling module for flow and cooling control.

[0005] This technical solution utilizes dynamic thermal management with multi-parameter feedback. By real-time monitoring of coil and coolant temperature and flow, combined with intelligent control via the MCU, efficient and safe heat dissipation is achieved. Specifically, when the stimulation coil generates a pulsed magnetic field, significant Joule heating is instantaneously generated due to coil resistance and eddy current losses. Temperature Sensors I and II are redundant to prevent cooling failures caused by pipe blockage or pump failure. Temperature Sensor I prioritizes the signal, while Temperature Sensor II serves as a secondary protection mechanism. An external liquid cooler and fan, respectively, cool the coil using coolant and airflow. The fan, built into the coil head, compensates for insufficient coolant dissipation under extreme heat. Furthermore, if Temperature Sensor I fails, a cross-validation mechanism, using Temperature Sensor II and flow detection, triggers a protection mechanism. The flow rate is controlled by the MCU, and feedback from the flow meter adjusts the power of the circulating pump to achieve fine-tuned coolant flow and prevent excessive temperature fluctuations. This technical solution realizes real-time temperature monitoring and dynamic cooling control of the stimulation coil of the transcranial magnetic stimulator by setting up a temperature acquisition module, a feedback control module, a flow regulation module, a flow detection module and a coolant cooling module, ensuring that the operating temperature of the coil is within a safe range when generating magnetic field pulses.

[0014] According to one embodiment of the present invention, the racket head has a built-in cooling liquid bag, which is a flexible bag separated by several cavities. The cooling liquid flows from the outer sleeve into one end of the cavity, traverses all the cavities, takes away the heat and flows out from the other end of the cavity.

[0015] This technical solution increases the contact area between the coolant and the coil and improves the cooling efficiency by building a coolant bag into the racket head and designing it as a flexible bag structure with several cavities spaced apart.

[0016] According to one embodiment of the present invention, the racket head is internally provided with a sealed spiral groove, and the cooling liquid of the outer sleeve flows into one end of the spiral groove and flows out through the other end of the spiral groove.

[0017] This technical solution uses a spiral groove with a built-in seal in the racket head to guide the coolant to form a spiral flow inside the racket head, enhancing the cooling effect and ensuring that the coil temperature is evenly reduced.

[0020] According to one embodiment of the present invention, in step S1, when the treatment starts, the user inputs the parameters of the transient current through the touch screen in the interactive module to adjust the intensity of the magnetic field pulse; the touch screen transmits the parameters input by the user to the MCU controller, and the MCU controller adjusts the working state of the transcranial magnetic stimulator according to the parameters.

[0021] This technical solution enables flexible adjustment of magnetic field pulse intensity to meet different treatment needs by introducing a step in which the user inputs transient current parameters through an interactive module.

[0022] According to one embodiment of the present invention, in step S2, if either temperature value I or temperature value II is abnormal and continues to exceed the threshold, the MCU controller sends a control signal to the alarm module, and the sound and light alarm sends an alarm signal to remind the staff to deal with the abnormal situation in time.
