[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The utility model discloses a microwave therapeutic apparatus, as shown in the attached Figure 1 As shown, the radiator 1 , a medium bag 2 , a storage box 3 , an inflow pipe 4 and an outflow pipe 5 are included.

[0056] The radiator 1 is used to emit microwaves. The radiator 1 is a part of the microwave emitting device. In addition to the radiator 1, the microwave emitting device also includes a microwave generator 24 and a microwave output line. The microwave generator 24 generates a microwave signal, which is transmitted to the radiator 1 by the microwave output line and then emitted outward by the radiator 1 to irradiate the diseased tissue.

[0057] As attached Figure 1 and 3 As shown, the medium bag 2 is arranged on the surface of the radiator 1 and can store a certain amount of medium. The thickness of the medium layer in the medium bag 2 and the material of the medium bag 2 are flexibly adjusted according to the design requirements and are not specifically limited here. It should be noted that the medium in the medium bag can be liquid, but is not limited to this, for example, it can also be gaseous. The selection of the type of medium in the medium bag, the determination of the thickness of the medium layer in the medium bag, and the anti-reflection and aggregation principles of the medium layer all belong to the prior art and will not be described in detail here.

[0058] The storage box 3 is used to store the medium. The structure of the storage box 3 can refer to the prior art and will not be described in detail here. The inflow pipe 4 and the outflow pipe 5 are respectively connected between the storage box 3 and the medium bag 2, so that the medium circulates between the medium bag 2 and the storage box 3. The medium in the storage box 3 first flows into the medium bag 2 through the inflow pipe 4, and then flows back to the storage box 3 along the outflow pipe 5.

[0059] When the medium bag 2 is filled with medium, a medium layer of a certain thickness will be formed in the medium bag 2. The medium layer can not only enhance the transmittance of the microwaves emitted by the radiator 1 and reduce the energy loss of the microwaves during the projection process, but also gather the microwaves emitted by the radiator 1 so that the microwaves can be concentrated in a small area to irradiate the lesion site, thereby effectively improving the therapeutic effect of microwave therapy.

[0060] As attached Figure 4 As shown, the microwave therapeutic apparatus further includes a main control valve 6, a circulation pipeline 7, a heater 8 and a reflux pipeline 9. The main control valve 6 is arranged between the inflow pipeline 4 and the outflow pipeline 5, and is used to control the on-off of the two pipelines. The main control valve 6 has an inflow channel 62 and an outflow channel 61, and the two channels can be opened or closed independently, and are used to control the inflow pipeline 4 and the outflow pipeline 5 respectively. Specifically, the inflow channel 62 is connected to the inflow pipeline 4, and is used to control the on-off of the inflow pipeline 4. The outflow channel 61 is connected to the outflow pipeline 5, and is used to control the on-off of the outflow pipeline 5. The main control valve 6 can be a solenoid valve, but is not limited to this.

[0061] The circulation pipeline 7 is connected to the storage box 3, so that the medium can circulate between the medium bag 2 and the storage box 3, and thus the medium in the storage box 3 can be heated and circulated before filling.

[0062] The heater 8 is arranged between the inflow pipeline 4 and the circulation pipeline 7, so that the circulation pipeline 7 is connected between the heater 8 and the storage box 3, so that the medium in the storage box 3 flows into the heater 8 through the circulation pipeline 7, and then flows into the medium bag 2 along the inflow pipeline 4 after being heated by the heater 8. The heater 8 includes a heating pool and a heating element. The heating pool is used to store the medium. The heating element can be a heating wire, etc., and its type and working principle can refer to the existing technology.

[0063] The reflux pipeline 9 is connected between the heater 8 and the storage box 3, so that the medium in the heater 8 flows back to the storage box 3 through the reflux pipeline 9, which can not only speed up the circulation speed of the medium and shorten the heating time, but also keep the internal and external pressure balance of the storage box 3, the heater 8 and the medium bag 2.

[0064] When the main control valve 6 is opened, that is, the inflow channel 62 and the outflow channel 61 of the main control valve 6 are both opened, the inflow channel 62 is connected to the inflow pipeline 4, and the outflow channel 61 is connected to the outflow pipeline 5. The medium in the storage box 3 first flows into the heater 8 along the circulation pipeline 7, and is divided into two paths after being heated by the heater 8. One path flows directly back to the storage box 3 along the return pipeline 9, and the other path flows into the medium bag 2 along the inflow pipeline 4 and then flows back to the storage box 3 along the outflow pipeline 5. At this time, the regulating valve 13 of the regulating pipeline 12 is closed, and the regulating pipeline 12 does not play a pressure regulating role. The storage box 3, the heater 8 and the medium bag 2 rely on the return pipeline 9 to maintain the internal and external pressure balance, and no medium is retained in the medium bag 2. This mode is the heating circulation mode, as shown in the attached Figure 4After the microwave therapeutic apparatus enters the heating circulation mode, the main control valve 6 is opened, the regulating valve 13 is closed, the circulation pump 10 enters the idle mode, and the medium circulates at a low speed between the medium bag 2, the intensifier and the storage box 3.

[0065] The outflow pipeline 5 is provided with a first filter 20 for preventing impurities in the medium bag 2 from flowing into the storage tank 3. The return pipeline 9 is provided with a second filter 21 for preventing impurities in the intensifier from flowing into the storage tank 3.

[0066] The circulation pipeline 7 is provided with a circulation pump 10. The circulation pump 10 has two modes, namely, a working mode and an idle mode. In the working mode, the circulation pump 10 runs at a high speed, and in the idle mode, the circulation pump 10 runs at a low speed. The structure and working principle of the circulation pump 10 can refer to the prior art.

[0067] When the circulation pump 10 enters the working mode and the outflow channel 61 of the main control valve 6 is closed, the medium bag 2 is not connected to the outflow pipeline 5, and only the inflow channel 62 of the main control valve 6 is connected to the inflow pipeline 4. Under the suction of the circulation pump 10, the medium in the storage box 3 first flows along the circulation pipeline 7 into the heater 8, and then flows into the medium bag 2 along the inflow pipeline 4 after being heated by the heater 8. The medium in the medium bag 2 cannot flow out along the outflow pipeline 5, so that the medium bag 2 is filled with liquid. This mode is the filling mode. Figure 5 and 6 As shown, after the microwave therapeutic apparatus enters the filling mode, the circulation pump 10 enters the working mode, the outflow channel 61 of the main control valve 6 is closed, and the inflow channel 62 is opened. It should be noted that in the filling mode, the medium in the heater 8 can still flow back directly to the storage tank 3 along the return line 9.

[0068] The microwave therapeutic apparatus further includes a regulating box 11, a regulating pipeline 12 and a regulating valve 13. The regulating box 11 is used to store a supplementary medium, and the supplementary medium is preferably in a gaseous state, but is not limited thereto. The regulating box 11 can increase the pressure of the storage box 3 by filling the supplementary medium into the storage box 3, and can also reduce the pressure of the storage box 3 by collecting the medium discharged from the storage box 3. The regulating pipeline 12 is connected between the storage box 3 and the regulating box 11, and the regulating valve 13 is provided in the regulating pipeline 12 for controlling the on and off of the regulating pipeline 12. The regulating valve 13 can be a solenoid valve, but is not limited thereto.

[0069] In the filling mode, when the circulation pump 10 enters the working mode and the regulating valve 13 is opened, the supplementary medium in the regulating box 11 flows into the storage box 3 along the regulating pipeline 12 until the internal and external pressures of the storage box 3 are balanced, so that the medium bag 2 can be quickly filled with liquid.

[0070] The microwave therapeutic apparatus further comprises a thickness detection element and a controller 14. The thickness detection element is used to detect the thickness of the medium layer formed in the medium bag 2, and can be a thickness sensor or a distance sensor, etc. The controller 14 is connected to the thickness detection element and the regulating valve 13 respectively.

[0071] When the thickness detection component detects that the thickness of the medium layer of the medium bag 2 is equal to the preset thickness, the filling is stopped, and the thickness detection component sends a signal to the controller 14. After receiving the signal, the controller 14 controls the outflow channel 61 of the main control valve 6 to open. At this time, the inflow channel 62 and the outflow channel 61 of the main control valve 6 are both opened; the controller 14 also controls the regulating valve 13 to close, so that the storage box 3, the heater 8 and the medium bag 2 maintain the internal and external pressure balance again, that is, the amount of medium flowing into the medium bag 2 is the same as the amount of medium flowing out of the medium bag 2, and the medium in the medium bag 2 is The mass volume remains unchanged, and the medium layer continues to maintain a preset thickness, so that the medium bag 2 is pressurized; the controller 14 controls the circulating pump 10 to enter the idle mode, and the medium in the storage box 3 first flows into the heater 8 along the circulation pipeline 7, and is divided into two paths after being heated by the heater 8. One path flows directly back to the storage box 3 along the return pipeline 9, and the other path flows into the medium bag 2 along the inflow pipeline 4 and then flows back to the storage box 3 along the outflow pipeline 5. That is, after the filling is completed, the microwave therapeutic device automatically enters the heating circulation mode to avoid excessive filling of the medium bag 2, and has higher safety.

[0072] When the thickness detector detects that the thickness of the medium layer of the medium bag 2 is less than the preset thickness, the control continues, and the thickness detector sends a signal to the controller 14. After receiving the signal, the controller 14 controls the circulation pump 10 to enter the working mode, and controls the regulating valve 13 to open, and continues to maintain the filling mode, so that the medium bag 2 continues to be filled with liquid.

[0073] The microwave therapeutic apparatus further comprises a connecting bridge 15 and a connecting pipeline 16. The connecting bridge 15 is arranged on the regulating pipeline 12 and is used to selectively connect the discharge pump 17 and the regulating pipeline 12. The interior of the connecting bridge 15 is interconnected, and its structure and working principle can be specifically referred to in the art. Both ends of the connecting pipeline 16 are respectively connected to the connecting bridge 15, so that the regulating pipeline 12 can remain unobstructed.

[0074] The regulating pipeline 12 is divided into three sections, including a first pipeline 121 connected between the storage box 3 and the regulating valve 13 , a second pipeline 122 connected between the regulating valve 13 and the connecting bridge 15 , and a third pipeline 123 connected between the connecting bridge 15 and the regulating box 11 .

[0075] In the filling mode, when the regulating valve 13 is opened, the supplementary medium in the regulating box 11 flows into the storage box 3 through the third pipeline 123, the connecting pipeline 16, the second pipeline 122, the regulating valve 13 and the first pipeline 121 in sequence, so that the storage box 3 maintains internal and external pressure balance when filling.

[0076] The microwave therapeutic apparatus further includes a discharge pump 17 connected to the connecting bridge 15, and the discharge pump 17 is used to pump the medium in the storage box 3 into the regulating box 11. The structure and working principle thereof may be specifically referred to in the prior art. The inlet of the discharge pump 17 is connected to the connecting bridge 15 through an input pipeline 18, and the outlet of the discharge pump 17 is connected to the connecting bridge 15 through an output pipeline 19.

[0077] When the discharge pump 17 is started and the regulating valve 13 is opened, the medium in the storage box 3 flows into the regulating box 11 through the first pipeline 121, the regulating valve 13, the second pipeline 122, the input pipeline 18, the discharge pump 17, the output pipeline 19 and the third pipeline 123 in sequence, and the medium in the storage box 3 is discharged to the regulating box 11, the internal pressure of the storage box 3 is reduced, and the medium in the medium bag 2 flows back to the storage box 3 along the outflow pipeline 5 due to the negative pressure. This mode is the liquid discharge mode. Figure 7 and 8 shown.

[0078] The medium bag 2 is arranged higher than the storage box 3. In addition to draining by negative pressure, the medium in the medium bag 2 can also flow into the storage box 3 along the outflow pipe 5 by gravity, which can also achieve drainage.

[0079] The microwave therapeutic apparatus further comprises a liquid level detection member for detecting the liquid level of the storage box 3, and the liquid level detection member may specifically be a liquid level sensor. The liquid level detection member and the discharge pump 17 are respectively connected to the controller 14, as shown in the attached Figure 2 and 9 When the liquid level detection component detects that the liquid level of the storage tank 3 is higher than its discharge port, the liquid level detection component sends a signal to the controller 14. After receiving the signal, the controller 14 controls the discharge pump 17 to start and controls the regulating valve 13 to open. The medium in the storage tank 3 flows into the regulating tank 11 through the first pipeline 121, the regulating valve 13, the second pipeline 122, the input pipeline 18, the discharge pump 17, the output pipeline 19 and the third pipeline 123 in sequence, realizing automatic liquid discharge and preventing the liquid level in the storage tank 3 from being too high.

[0080] The microwave therapeutic apparatus further comprises a temperature detection element for detecting the temperature of the medium in the medium bag 2 and an alarm for sounding an alarm. The temperature detection element may specifically be a temperature sensor. The temperature detection element, the heater 8 and the alarm are all connected to the controller 14. When the temperature of the medium in the medium bag 2 is lower than the set temperature, the temperature detection element sends a signal to the controller 14. After receiving the signal, the controller 14 starts the heater 8 and automatically adjusts the temperature of the medium in the medium bag 2 so that the medium in the medium bag 2 is kept within the set range. When the liquid level detection element detects that the hydraulic height in the storage box 3 is lower than the minimum liquid level, the liquid level detection element sends a signal to the controller 14. After receiving the signal, the controller 14 starts the alarm to automatically remind the user to replenish the medium to avoid too little medium in the storage box 3.

[0081] In addition, the microwave therapeutic apparatus further comprises a display screen 22 and a switching power supply 23. The display screen 22 is a display interface and also a human-machine exchange interface. The switching power supply 23 transforms the mains electricity into the required power supply for powering the entire apparatus.

[0082] It should be noted that the controller 14 should include a signal receiving unit, a signal judging unit and a signal sending unit. The signal receiving unit is used to receive electrical signals sent by detection components such as thickness detection components, liquid level detection components and temperature detection components. The signal judging unit and the signal receiving unit are electrically connected so that the signal judging unit is used to judge whether the signal received by the signal receiving unit is a trigger signal. The signal sending unit and the signal judging unit are electrically connected so that the signal sending unit sends the judgment signal generated by the signal judging unit to the actuator such as the regulating valve 13 or the alarm. The specific setting methods of the signal receiving unit, the signal judging unit and the signal sending unit can refer to the prior art; in the present utility model, only the application scenarios of the above three are changed, and no substantial improvement is made to them. Obviously, the controller 14 with this structure is widely used in existing automatic control equipment, such as MCU, DSP or single-chip microcomputer. The key point of the present utility model is that the controller 14 combines each detection component and each actuator in pairs.

[0083] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0084] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
