[0030] High-intensity focused ultrasound therapy is a new type of tumor treatment method. When using this method to treat tumors, ultrasound positioning can be used, and high-intensity ultrasound can be used to kill tumor cells in the target area without damaging surrounding normal tissues, thereby achieving minimally invasive treatment of tumor tissues. Since ultrasound waves decay quickly in the air, degassed water is generally used as the transmission medium for ultrasound waves during the actual treatment process. Therefore, the stable circulation of degassed water is a key step to ensure high-intensity focused ultrasound therapy. Based on this, the present invention provides a degassed water circulation device that can stably circulate degassed water and a high-intensity focused ultrasound therapeutic device.

[0031] like Figure 1As shown, an embodiment of the present invention provides a degassed water circulation device 10, and the circulating water degassing device includes a water circulation pipeline 100 and a detection pipeline 200. The water circulation pipeline 100 is used to maintain the circulation of degassed water 30, and the water circulation pipeline 100 can be connected to the water inlet 501 and the water outlet 502 of the ultrasonic transducer 50 respectively. The detection pipeline 200 is connected to the water circulation pipeline 100, and when the detection pipeline 200 is connected to the water circulation pipeline 100, the sealing performance of the water circulation pipeline 100 and the ultrasonic transducer 50 can be detected. In the above-mentioned degassed water circulation device 10, before the water circulation pipeline 100 circulates and transports the degassed water 30, the detection pipeline 200 is connected to the water circulation pipeline 100, and the sealing performance of the water circulation pipeline 100 is detected. Preliminary detection of the sealing performance of the water circulation pipeline 100 effectively ensures the stable circulation and transportation process of the degassed water 30 by the water circulation pipeline 100, thereby ensuring the smooth progress of the ultrasonic treatment process.

[0032] The function of the water circulation pipeline 100 is to degas the degassed water 30 and to stably circulate the degassed water 30 into the transducer. Figure 1 As shown, in one embodiment of the present invention, the water circulation pipeline 100 includes a water storage tank 101, a circulation pump 102, a degassing component and a circulation pipeline 105. The degassing component is used to remove gas from the water. The circulation pipeline 105 can be connected to the water inlet 501 and the water outlet 502 of the ultrasonic transducer 50 respectively to form a closed loop. The circulation pipeline 105 is connected in series with the water storage tank 101, the circulation pump 102 and the degassing component in the direction of water flow. The circulation pump 102 pumps the water in the water storage tank 101 to the degassing component, and the circulation pipeline 105 transports the degassed water 30 after the gas is removed to the ultrasonic transducer 50. The water storage tank 101 receives the degassed water 30 flowing through the ultrasonic transducer 50. The detection pipeline 200 is connected to the circulation pipeline 105. When the detection pipeline 200 is connected to the circulation pipeline 105, the sealing performance of the water circulation pipeline 100 can be detected. As an achievable manner, the type of the circulation pump 102 includes a variable frequency speed regulating water pump, which provides power for the circulation of the deaerated water 30 in the entire deaerated water circulation device 10 .

[0033] In the above embodiment, the water detection pipeline 200 is connected to the circulation pipeline 105, and the structure is simple and the connection is stable. The circulation pump 102 serves as the power source of the entire water circulation pipeline 100, ensuring that the degassed water 30 flows in the circulation pipeline 105 in a set direction and flow rate. The water storage tank 101 serves as a temporary storage location for the degassed water 30, continuously delivering the stored degassed water 30 to the circulation pump 102, while continuously receiving the degassing after passing through the ultrasonic transducer 50. The water storage tank 101 and the circulation pump 102 cooperate to ensure the stable circulation of the degassed water 30 along the circulation pipeline 105. Figure 1As shown, further, the degassing component includes a degassing membrane structure 103 and a vacuum pump 104, the degassing membrane structure 103 is connected in series to the circulation pipeline 105, and the degassing membrane structure 103 degasses the water transported by the circulation pump 102. The vacuum pump 104 is connected to the degassing membrane structure 103, and is used to discharge the gas generated during the degassing process from the degassing membrane structure 103. Furthermore, the water circulation pipeline 100 also includes a gas content detector 113, and the gas content detector 113 is arranged in the water storage tank 101, and the gas content detector 113 can monitor the gas content in the degassed water 30 in real time. As a feasible way, the gas detector is electrically connected to the degassing membrane structure 103, and the gas detector can transmit the gas content data in the degassed water 30 to the degassing membrane structure 103, and the degassing membrane structure 103 can adjust its own degassing parameters according to the gas content data in the degassed water 30.

[0034] The quality of degassed water 30 is a prerequisite for ensuring the effective implementation of the high-intensity focused ultrasound treatment process. Figure 1 As shown, in one embodiment of the present invention, the water circulation pipeline 100 further includes a first filter 106, which is serially connected to the circulation pipeline 105, and is disposed between the circulation pump 102 and the degassing component along the water flow direction. The degassed water 30 delivered by the circulation pump 102 first passes through the first filter 106, which can effectively remove tiny particles in the degassed water 30, ensure the purity of the degassed water 30 flowing through the degassing component and the ultrasonic transducer 50, and further ensure the smooth degassing process of the degassing component and the smooth treatment process of the ultrasonic transducer 50.

[0035] Maintaining the water temperature of the degassed water 30 within the set range is a prerequisite for ensuring the effective implementation of the high-intensity focused ultrasound treatment process. Therefore, it is particularly important to ensure the water temperature of the degassed water 30 during the circulation process, especially the water temperature of the degassed water 30 when it flows through the ultrasonic transducer 50. Figure 1 As shown, in one embodiment of the present invention, the water circulation pipeline 100 further includes a temperature regulating component, which is used to adjust the water temperature of the deaerated water 30. The temperature regulating component is connected in series to the circulation pipeline 105, and the temperature regulating component is arranged downstream of the deaeration component along the water flow direction. The circulation pipeline 105 transports the deaerated water 30 after the water temperature is adjusted to the ultrasonic transducer 50. The temperature regulating component effectively ensures that the water temperature of the deaerated water 30 is maintained within the set range. Generally, as the circulation process of the deaerated water 30 increases, the water temperature of the deaerated water 30 itself also gradually increases.

[0036] As a feasible approach, Figure 1As shown, the temperature adjustment component includes a chiller 107 and a temperature sensor 108, and the chiller 107 and the temperature sensor 108 are connected in series to the circulation pipe 105 in the direction of water flow. The chiller 107 is used to cool the degassed water 30 to a set temperature range, and the degassed water 30 after degassing enters the chiller 107 through the circulation pipe 105 for appropriate range of temperature reduction. The temperature sensor 108 is used to monitor the water temperature of the degassed water 30, and then determine whether the degassed water 30 is within the set water temperature range. Further, the temperature sensor 108 is electrically connected to the chiller 107, and the temperature sensor 108 can transmit the water temperature data of the degassed water 30 to the chiller 107. The chiller 107 adjusts its own operating parameters according to the water temperature data fed back by the temperature sensor 108, and further ensures that the water temperature of the degassed water 30 is maintained within the set temperature range.

[0037] The quality of the degassed water 30 is a prerequisite for ensuring that the high-intensity focused ultrasound treatment process is carried out effectively. Figure 1 As shown, the water circulation pipeline 100 also includes a second filter 109, which is serially connected to the circulation pipeline 105. The second filter 109 is arranged downstream of the temperature adjustment component along the water flow direction, and the circulation pipeline 105 conveys the degassed water 30 filtered by the second filter 109 to the ultrasonic transducer 50. The second filter 109 can effectively filter the degassed water 30 flowing through the chiller 107, further remove tiny particles in the degassed water 30, ensure the purity of the degassed water 30 flowing through the ultrasonic transducer 50, and further ensure the smooth progress of the treatment process of the ultrasonic transducer 50.

[0038] The deaerated water 30 needs to maintain a certain water pressure when circulating in the circulation pipe 105 and the ultrasonic transducer 50. Figure 1 As shown, the water circulation pipeline 100 also includes a pressure sensor 110 and a circulation check valve 111. The pressure sensor 110 and the circulation check valve 111 are serially connected to the circulation pipeline 105 in the direction of water flow, and the pressure sensor 110 and the circulation check valve 111 are respectively arranged upstream of the water storage tank 101 in the direction of water flow. The water storage tank 101 receives the degassed water 30 that flows through the ultrasonic transducer 50, the pressure sensor 110 and the circulation check valve 111 in sequence. The pressure sensor 110 is used to detect the fluid pressure value in the water circulation pipeline 100. The pressure sensor 110 is adjacent to the ultrasonic transducer 50 and can effectively monitor the pressure value of the degassed water 30 filled in the ultrasonic transducer 50.

[0039] Furthermore, the pressure sensor 110 is electrically connected to the circulation pump 102, and the pressure sensor 110 can transmit the fluid pressure value in the water circulation pipeline 100 and the ultrasonic transducer 50 to the circulation pump 102. Then the circulation pump 102 adjusts its own working parameters (such as the rotation speed of the circulation pump 102) or the output pressure of the degassed water 30 according to the pressure value of the degassed water 30, and finally ensures that the pressure value of the degassed water 30 in the ultrasonic transducer 50 is maintained within a safe range, preventing the ultrasonic transducer 50 and the degassed water circulation device 10 from leaking due to excessive water pressure.

[0040] The circulation check valve 111 can prevent the degassed water 30 in the water storage tank 101 from flowing back into the ultrasonic transducer 50. After the patient treatment is completed, the patient's head is separated from the ultrasonic transducer 50, resulting in the ultrasonic transducer 50 being no longer airtight. At this time, if the degassed water 30 flows back, it may cause the magnetic resonance bed to malfunction. Figure 1 As shown, the circulation check valve 111 includes one or both of a mechanical check valve and an electronic check valve. During the guidance of magnetic resonance imaging, there is a high magnetic field effect. If the structure around the ultrasonic transducer 50 has a strong magnetic sensitivity, it will greatly affect the quality of subsequent imaging. In one embodiment of the present invention, the material of the connection part between the circulation pipe 105 and the transducer includes a non-magnetic material, such as a rubber pipe or a plastic pipe, which greatly improves the quality of imaging, thereby avoiding misjudgment of symptoms due to imaging problems caused by equipment materials.

[0041] The quality of the degassed water 30 is a prerequisite for ensuring that the high-intensity focused ultrasound treatment process is carried out effectively. Figure 1 As shown, the water circulation pipeline 100 also includes a sterilization lamp tube 112, and the sterilization lamp tube 112 is arranged in the water storage tank 101. The sterilization lamp tube 112 is used to sterilize the degassed water 30 that is continuously circulated in the entire degassed water circulation device 10, thereby ensuring the sterility of the water used in the entire degassed water circulation device 10, and ensuring that even if the patient's head is injured, it will not be infected. It can be understood that the sterilization lamp tube 112 can emit one or more rays that can kill bacteria. As a feasible method, the sterilization lamp tube 112 emits ultraviolet light, and the sterilization lamp tube 112 is immersed in the degassed water 30 in the water storage tank 101, which increases the contact area and contact distance between the sterilization lamp tube 112 and the degassed water 30, and ensures the effective implementation of the sterilization process.

[0042] The detection pipeline 200 is a key structure for predicting the sealing performance of the water circulation pipeline 100 and the ultrasonic transducer 50 in the deaerated water circulation device 10. Optionally, the detection pipeline 200 can detect the sealing performance of the water circulation pipeline 100 and the ultrasonic transducer 50 through gas or liquid. Figure 1As shown, the detection pipeline 200 includes a detection pipeline 201, an air pump 202, a three-way valve 203 and an air tightness detector 204. The detection pipeline 201 is connected to the circulation pipeline 105 through the three-way valve 203, and the air pump 202 and the air tightness detector 204 are respectively connected to the detection pipeline 201. When the detection pipeline 201 is connected to the circulation pipeline 105, the air pump 202 fills the detection pipeline 201 with gas of a set pressure, and the air tightness detector 204 is used to monitor the change of the air pressure in the detection pipeline 201. Using gas as a detection medium for the sealing performance of the water circulation pipeline 100 and the ultrasonic transducer 50, even if the sealing performance of the water circulation pipeline 100 or the ultrasonic transducer 50 is not good, it will not cause pollution to the medical equipment and the medical space.

[0043] In one embodiment of the present invention, Figure 1 As shown, the water circulation pipeline 100 also includes a circulation switch 114, which is arranged upstream of the water storage tank 101 along the water flow direction, and the position where the three-way valve 203 is connected to the circulation pipeline is located upstream of the ultrasonic transducer 50 along the water flow direction. The detection pipeline 200 also includes a detection switch 205 and a gas filter 206, and the air tightness detector 204 is arranged downstream of the air pump 202 along the gas flow direction during inflation. The detection switch 205 and the gas filter 206 are respectively connected in series to the detection pipeline 201, and the detection switch 205 and the gas filter 206 are respectively arranged between the air pump 202 and the air tightness detector 204. As a feasible method, the gas delivered to the detection pipeline 201 by the air pump 202 is air, and the gas filter 206 can effectively filter the tiny particles in the air to ensure the cleanliness of the detection pipeline 201, the circulation pipeline 105 and the ultrasonic transducer 50.

[0044] In the above embodiment, the circulation switch 114 is in the closed state, the detection switch 205 is in the open state, the three-way valve 203 connects the detection pipeline 201 and the circulation pipeline 105 to the side of the ultrasonic transducer 50, the gas filter 206 filters the gas filled into the detection pipeline 201 by the air pump 202, and when the gas in the detection pipeline 201 reaches the set pressure, the detection switch 205 closes the detection pipeline 201, and the air tightness detector 204 monitors the change of the air pressure in the detection pipeline 201. The detection switch 205 and the circulation switch 114 can effectively form a closed space formed by part of the detection pipeline 201, part of the circulation pipeline 105 and the ultrasonic transducer 50, which is conducive to the air tightness detector 204 to accurately detect the sealing performance of the circulation pipeline 105 and the ultrasonic transducer 50. When the air pressure value in the detection pipeline 201 drops significantly in a short time, it means that the sealing performance of the water circulation pipeline 100 or the super energy transducer is not good, and further investigation is required.

[0045] Further, if Figure 1As shown, the detection switch 205 is arranged downstream of the gas filter 206 along the gas flow direction during inflation, and the detection pipeline 200 also includes a gas storage tank 207, which is connected in series to the detection pipeline 201, and the gas storage tank 207 is arranged between the gas filter 206 and the detection switch 205. When the detection switch 205 is closed, the gas storage tank 207 stores and compresses the gas filtered by the gas filter 206. When the detection switch 205 is turned on, the compressed gas in the gas storage tank 207 is filled into the detection pipeline 201 through the detection switch 205. By storing and compressing the gas delivered by the air pump 202 in the gas storage tank 207, it can be ensured that the compressed gas stably enters the detection pipeline 201, the circulation pipeline 105 and the ultrasonic transducer 50. As a feasible way, Figure 1 As shown, when the circulation switch 114 is in the closed state and the detection switch 205 is in the open state, the three-way valve 203 connects the detection pipeline 201 and the circulation pipeline 105 to one side of the ultrasonic transducer 50, and the gas in the gas storage tank 207 stably enters the circulation pipeline and the ultrasonic transducer 50 through the detection pipeline 200. The pressure sensor 110 located downstream of the ultrasonic transducer 50 can monitor the air pressure value in the circulation pipeline 105. When the pressure value in the circulation pipeline 105 reaches the set value, the detection switch 205 is closed and the air tightness detector 204 is started.

[0046] Under the premise of fixed volume, the gas storage tank 207 can store gas with a set upper pressure limit. Figure 1 As shown, the detection pipeline 200 also includes an air pressure sensor 208, which is arranged in the gas storage tank 207, and the air pressure sensor 208 can monitor the air pressure value in the gas storage tank 207 in real time. The air pressure sensor 208 is electrically connected to the air pump 202, and the air pressure sensor 208 can transmit the pressure value in the gas storage tank 207 to the air pump 202. When the pressure in the gas storage tank 207 reaches the set value, the air pump 202 stops pumping gas into the gas storage tank 207. Further, the detection pipeline 200 also includes a detection check valve 209, which is connected in series to the detection pipeline 201, and the detection check valve 209 is arranged between the gas storage tank 207 and the detection switch 205 along the gas flow direction during inflation. The detection check valve 209 can ensure that the gas flows in a single direction.

[0047] like Figure 1As shown, an embodiment of the present invention further provides a high-intensity focused ultrasound therapeutic apparatus, comprising an ultrasonic transducer 50 and a degassed water circulation device 10 as described in any one of the above schemes, wherein the ultrasonic transducer 50 has a water inlet 501 and a water outlet 502, and the water circulation pipeline 100 can be connected to the water inlet 501 and the water outlet 502 of the ultrasonic transducer 50, respectively, and the position where the detection pipeline 200 is connected to the water circulation pipeline 100 is located upstream of the water inlet 501 along the water flow direction. The water circulation pipeline 100 can provide circulating degassed water 30 into the ultrasonic transducer 50, and the detection pipeline 200 can detect the sealing performance of the water circulation pipeline 100 and the ultrasonic transducer 50 by means of inflation. Furthermore, the ultrasonic transducer 50 is hemispherical, and the structural design shape of the ultrasonic transducer 50 is conducive to encompassing the entire brain, facilitating the coverage of the ultrasonic treatment target at any position of the entire brain by the positioning target of the entire ultrasonic module, and facilitating the ultrasonic transducer 50 to be sealed with water in the head during the treatment process, thereby facilitating the conduction of ultrasonic energy. At the same time, after the kinetic energy generated by the ultrasonic transducer 50 is converted into thermal energy during the entire treatment process, the heat generated can be carried away by the flow of degassed water 30. Furthermore, in the high-intensity focused ultrasound therapeutic device, only the ultrasonic transducer 50 is installed in the nuclear magnetic resonance room for use, and the rest of the structures are installed outside the nuclear magnetic resonance room to avoid affecting the nuclear magnetic resonance imaging effect.
