[0002] An Energy Therapy Device is a device that uses physical energy (such as electrical energy, light energy, magnetic energy, sound energy, thermal energy, etc.) to act on the human body to achieve medical or health care purposes. Such devices can help relieve symptoms, promote recovery or improve health by adjusting the energy state or physiological functions of the human body. Taking the ablation device commonly used in energy therapy devices as an example, the ablation device can transfer energy to the target tissue area through a specific energy form (such as radio frequency, microwave, laser, cryo, etc.), causing the temperature of the target tissue area to change, and then causing irreversible damage or death of the cells in this area, while minimizing the impact on the surrounding normal tissues. Therefore, some energy therapy devices essentially belong to an electric heating device. By studying and improving the output thermal energy and electrothermal efficiency of energy therapy devices, it can ensure that more input energy is converted into effective thermal energy of the target tissue, thereby achieving precise destruction of diseased tissues, improving the treatment effect, and reducing energy consumption.

[0003] Among them, the electrothermal efficiency refers to the effective degree of converting electrical energy into thermal energy, and is usually used to measure the performance of an electric heating device during the energy conversion process.

Detailed implementation manners

[0020] The following further describes in detail a measuring device and method for output thermal energy and electrothermal efficiency of an energy treatment device provided by the present invention with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will be clearer according to the following description and the claims.

[0021] First embodiment Refer to Figures 1-4 , this embodiment provides a measuring device for output thermal energy and electrothermal efficiency of an energy treatment device, which is used to automatically and accurately realize the measurement function of the output thermal energy and electrothermal efficiency of the energy treatment device 5. The main structure of the measuring device includes a frame 1, a carrier container 2, a driving assembly 4, and a temperature measuring unit 3.

[0022] The carrier container 2 is a hollow cylindrical structure with an opening at the top and a closed bottom, and its internal cavity is used to hold a heat absorption carrier.

[0023] In this embodiment, the heat absorption carrier can be selected as liquid media such as pure water and oil.

[0024] The distal ends of the driving assembly 4 are respectively fixedly provided with a temperature measuring unit 3 and an installation interface 10. The installation interface 10 is used for detachably fixing the energy treatment device 5 to be measured. That is, according to the measurement requirements, different energy treatment devices 5 to be measured can be detachably fixedly installed at the distal end of the driving assembly 4. In this embodiment, the driving assembly 4 can drive the temperature measuring unit 3 to move into the inner chamber of the carrier container 2, so that the measuring end of the temperature measuring unit 3 contacts the heat absorption carrier. At the same time, it can also drive the energy treatment device 5 to move into the inner chamber of the carrier container 2, so that the output end of the energy treatment device 5 is in full contact with the heat absorption carrier.

[0025] In this embodiment, after the driving assembly 4 drives the output end of the energy treatment device 5 to contact the heat absorption carrier, the output end of the energy treatment device 5 is enabled to release heat to the heat absorption carrier. Then, the measuring end of the temperature measuring unit 3 measures the temperature difference of the heat absorption carrier before and after the temperature change respectively, and calculates and obtains the heat absorption data of the heat absorption carrier. The heat absorption data of the heat absorption carrier is the output thermal energy of the energy treatment device 5.

[0026] It is worth noting that in this embodiment, the energy treatment device 5 to be measured includes energy release devices such as electromagnetic wave devices, phototherapy devices, ultrasonic devices, and electrotherapy devices that can achieve electro-thermal conversion. Taking the ablation device as an example, it can specifically include microwave ablation needles, radiofrequency ablation needles, laser ablation needles, cryoablation needles, etc. And for the measurement types of the output thermal energy and electro-thermal efficiency of the energy treatment device 5, it not only includes the energy treatment device 5 outputting a heat source to increase the temperature of the heat absorption carrier, but also includes the energy treatment device 5 outputting a cold source to decrease the temperature of the heat absorption carrier.

[0027] Next, the specific structure and function of a measuring device for the output thermal energy and electro-thermal efficiency of an energy treatment device provided in this embodiment will be further described in detail: Preferably, in an embodiment, the measuring device is further provided with a power acquisition unit. The power acquisition unit is electrically connected to the energy treatment device 5 and is used for measuring the total output electrical energy of the energy treatment device 5 when releasing heat.

[0028] Therefore, in this embodiment, after the driving assembly 4 drives the output end of the energy treatment device 5 to contact the heat absorption carrier and enables the output end of the energy treatment device 5 to release heat to the heat absorption carrier, the power acquisition unit synchronously measures the effective current value and the effective voltage value of the energy treatment device 5 when releasing heat. From this, the total output electrical energy of the energy treatment device 5 is calculated and generated. Finally, based on the output electrical energy and output thermal energy of the energy treatment device 5, the electro-thermal efficiency of the energy treatment device 5 can be further calculated.

[0029] Preferably, in one embodiment, a heat preservation component 6 extending in a vertical direction is provided in the frame 1, a containing cavity is provided inside the heat preservation component 6, and an opening is provided at the top thereof.

[0030] The heat-insulating component 6 is made of a material with low thermal conductivity, which can prevent heat conduction itself and has a heat-insulating effect.

[0031] The volume of the carrier container 2 is adapted to the volume of the internal accommodating cavity of the insulation component 6, that is, the carrier container 2 can be movably arranged in the accommodating cavity of the insulation component 6. When the carrier container 2 is placed in the accommodating cavity of the insulation component 6, the height of the carrier container 2 is adapted to the height of the accommodating cavity of the insulation component 6, and the outer wall surface of the carrier container 2 is in contact with the inner wall surface of the accommodating cavity of the insulation component 6.

[0032] In this embodiment, during the measurement process of the electrothermal efficiency measuring device, the carrier container 2 can be manually removed from the insulation component 6, a heat absorbing carrier is injected into the carrier container 2, and then the carrier container 2 is replaced in the accommodating cavity of the insulation component 6. The insulation component 6 is wrapped around the outside of the carrier container 2, and because of its own poor thermal conductivity, it can reduce the heat of the heat absorbing carrier from escaping to the external environment through the insulation component 6, which helps to maintain the temperature stability of the heat absorbing carrier inside the carrier container 2 and avoid the interference of external temperature fluctuations on the measurement results.

[0033] Preferably, in one embodiment, the driving assembly 4 includes a first driving arm 7 and a second driving arm 8 extending in a horizontal direction, and one end of the first driving arm 7 and the second driving arm 8 are fixedly connected to the same rotating shaft, so that the first driving arm 7 and the second driving arm 8 can rotate around the rotating shaft, and the end of the first driving arm 7 and the second driving arm 8 fixedly connected to the rotating shaft is set as its proximal end, and the end of the first driving arm 7 and the second driving arm 8 away from the rotating shaft is set as its distal end.

[0034] The proximal ends of the first driving arm 7 and the second driving arm 8 are connected and fixed together, and a fixed angle is maintained between the first driving arm 7 and the second driving arm 8, that is, the first driving arm 7 and the second driving arm 8 form a V-shaped structure.

[0035] The proximal ends of the first driving arm 7 and the second driving arm 8 are rotatably connected to the frame 1 via a lifting and rotating shaft 9 extending in the vertical direction. A motor assembly is provided inside the frame 1, and the motor assembly is transmission-connected to the lifting and rotating shaft 9. The motor assembly is used to drive the lifting and rotating shaft 9 to perform horizontal rotation and vertical lifting movements, thereby driving the first driving arm 7 and the second driving arm 8 to synchronously generate horizontal rotation and vertical lifting movements.

[0036] The distal end of the second driving arm 8 is provided with a mounting interface 10, and the mounting interface 10 is used for detachably fixing and connecting the energy treatment device 5 to be measured.

[0037] In this embodiment, the lengths of the first driving arm 7 and the second driving arm 8 from the proximal end to the distal end are kept the same. When the first driving arm 7 rotates horizontally above the carrier container 2, the temperature measuring unit 3 at the distal end of the first driving arm 7 is coaxially arranged with the carrier container 2. When the first driving arm 7 moves vertically downward, the measuring end of the temperature measuring unit 3 can extend into the inner chamber of the carrier container 2, so that the measuring end of the temperature measuring unit 3 contacts the heat absorption carrier. When the second driving arm 8 rotates horizontally above the carrier container 2, the energy treatment instrument 5 at the distal end of the second driving arm 8 is coaxially arranged with the carrier container 2. When the second driving arm 8 moves vertically downward, the output end of the energy treatment instrument 5 can extend into the inner chamber of the carrier container 2, so that the output end of the energy treatment instrument 5 contacts the heat absorption carrier.

[0038] Through the structural settings of the first driving arm 7 and the second driving arm 8, the motion control logic of the driving assembly 4 can be simplified. Taking the proximal ends of the first driving arm 7 and the second driving arm 8 as the rotation centers, the distance from the carrier container 2 to the rotation center is equal to the lengths of the first driving arm 7 and the second driving arm 8. In this application, only by controlling the horizontal rotation amount and the vertical lifting amount of the first driving arm 7 and the second driving arm 8, the temperature measuring unit 3 or the energy treatment instrument 5 can be efficiently driven to move into the inner chamber of the carrier container 2, improving the moving efficiency of the first driving arm 7 and the second driving arm 8 and the efficiency of the overall measurement operation. Furthermore, the heat dissipation generated by the contact between the heat absorption carrier and the external environment during the process of the temperature measuring unit 3 and the energy treatment instrument 5 moving into and out of the carrier container 2 can be reduced.

[0039] Preferably, in one embodiment, a weighing platform 11 is provided in the frame 1. The weighing end of the weighing platform 11 receives the bottom of the heat preservation assembly 6, and there is a certain gap between the outer wall surface of the heat preservation assembly 6 and other structures of the frame 1 except for the contact with the weighing platform 11, thus avoiding the frame 1 applying external force to the heat preservation assembly 6 and causing errors in the weighing result.

[0040] In this embodiment, the weighing platform 11 is used to measure the total mass of the carrier container 2, the heat preservation assembly 6 and the heat absorption carrier contained in the carrier container 2. Since the masses of the carrier container 2 and the heat preservation assembly 6 are known in advance, the weighing platform 11 can automatically subtract the masses of the carrier container 2 and the heat preservation assembly 6 and only output the individual mass of the heat absorption carrier contained in the carrier container 2. Through the automated weighing process, the operation process can be effectively simplified, and the errors that may be introduced by manual measurement and calculation can be avoided.

[0041] Preferably, in one embodiment, a stirring part 12 is provided at the bottom end of the temperature measuring unit 3. When the measuring end of the temperature measuring unit 3 extends into the inner chamber of the carrier container 2 and contacts the heat absorption carrier, the stirring part 12 is arranged along the height direction of the inner chamber of the carrier container 2 and is wholly or partially immersed in the heat absorption carrier.

[0042] In the present application, the target heating area range of some energy treatment devices 5 is small, and the overall heating and measuring time of the electrothermal efficiency measuring device is short. Therefore, after the energy treatment device 5 releases heat to the heat absorption carrier, the heat inside the heat absorption carrier may be unevenly distributed. By providing the stirring part 12, it can be used to uniformly stir the heat absorption carrier in the carrier container 2, so that the temperatures of its liquid layers are kept consistent, improving the reliability and accuracy of the heat absorption carrier temperature measurement.

[0043] Among them, the stirring part 12 is provided with a stirring shaft and a plurality of stirring paddles, and the plurality of stirring paddles are respectively fixedly connected to the stirring shaft.

[0044] In one embodiment, the stirring shaft is made of a high-resistance material to form a resistive heating structure. The stirring shaft is electrically connected to a power supply, and electric energy is directly supplied to the stirring shaft by the power supply. In theory, the stirring shaft can convert all the electric energy into heat energy output. The total amount of electric energy Q output by the stirring shaft 1 The calculation method is: Q 1 =P*t Among them, P is the output power of the stirring shaft, and t is the output time of the stirring shaft.

[0045] In this embodiment, since the temperature measuring unit 3 and the energy treatment device 5 need to be moved into and out of the carrier container 2 successively, during this process, the heat absorption carrier will inevitably come into contact with the external environment through the top opening of the carrier container 2, and part of the heat will be absorbed by the carrier container 2, resulting in heat dissipation of the heat absorption carrier. Therefore, a stirring shaft made of a high-resistance material is provided to simulate and calculate the dissipated heat. Specifically: After obtaining the total output electric energy of the energy treatment device 5 and the absorbed heat of the heat absorption carrier, the measuring device is restored to the initial state, and the same mass m as in the previous measurement operation is re-injected into the carrier container 2 1 , and the same temperature T 1The heat absorption carrier, and then control the stirring shaft to be completely immersed in the heat absorption carrier, and heat the heat absorption carrier with a preset output power and output time. Wherein, the output power and output time of the stirring shaft are set according to the total theoretical output electric energy of the energy treatment device 5 to be measured. That is, the heat absorption carrier is heated to a preset temperature through the stirring shaft. The preset temperature refers to the temperature of the heat absorption carrier when the energy treatment device 5 finishes heating in the previous measurement operation. Subsequently, the stirring shaft is removed from the heat absorption carrier to enable the heat absorption carrier to exchange heat with the external environment, simulating the working condition of the heat absorption carrier exchanging heat with the external environment in the previous measurement operation. After the heat absorption carrier reaches the preset contact time with the external environment, control the measuring end of the temperature measuring unit 3 to enter the carrier container 2 to measure the temperature T of the heat absorption carrier at this time 2 , according to the temperature difference of the heat absorption carrier, the absorbed heat of the heat absorption carrier after heat dissipation can be calculated, that is Q 2 =c*m 1 *(T 2 -T 1 ) Wherein, c is the specific heat capacity of the heat absorption carrier

[0046] Finally, calculate Q 2 and Q 1 , and the result is the dissipated heat existing in the heat absorption carrier during the test

[0047] When finally calculating the output thermal energy and electrothermal efficiency of the energy treatment device 5, the dissipated heat of the heat absorption carrier needs to be added to the actually measured absorbed heat of the heat absorption carrier to achieve data compensation and improve the calculation accuracy of the output thermal energy and electrothermal efficiency of the energy treatment device 5

[0048] In another embodiment, the acquisition of the dissipated heat can also be realized by the chemical exothermic method. Specifically, a certain mass m 2 of calcium oxide or anhydrous calcium chloride is put into a medium container filled with water and stirred. The mass of calcium oxide or anhydrous calcium chloride is set according to the total theoretical output electric energy of the ablation device to be measured. During the stirring process, calcium oxide or anhydrous calcium chloride reacts with water to release heat, and the heat release calculation method is Q 3 =m 2 *ΔH*M Wherein, ΔH is the enthalpy change of the reaction between calcium oxide or anhydrous calcium chloride and the heat absorption carrier, and M is the molar mass of calcium oxide or anhydrous calcium chloride

[0049] Similarly, simulate the working condition of the heat absorption carrier exchanging heat with the external environment in the previous measurement operation. Finally, calculate Q 3 and Q 2The difference is the dissipated heat of the heat absorption carrier during the test.

[0050] Among them, the dissipated heat of the heat absorption carrier measured by the electric heating method or the chemical exothermic method includes both the heat absorbed by the carrier container 2 from the heat absorption carrier and the heat lost by the heat absorption carrier through heat exchange with the external environment through the top opening of the carrier container 2.

[0051] Preferably, in one embodiment, a plurality of first temperature sensors 13 are provided at the measurement end of the temperature measurement unit 3, and the plurality of first temperature sensors 13 are evenly circumferentially arranged on the side wall of the temperature measurement unit 3 along the height extension direction of the temperature measurement unit 3 for detecting the temperature of each liquid layer of the heat absorption carrier.

[0052] In this embodiment, when the stirring part 12 stirs the heat absorption carrier in the carrier container 2, if the temperature parameters of each liquid layer of the heat absorption carrier detected by each first temperature sensor 13 are the same, it proves that the heat distribution in the heat absorption carrier is uniform, and at this time, the stirring part 12 can be controlled to stop stirring.

[0053] Preferably, in one embodiment, a seal 14 is sleeved on the circumferential side wall above the measurement end of the temperature measurement unit 3, and the seal 14 is an annular planar structure. The frame 1 is provided with a vertically arranged accommodating groove for placing the carrier container 2 and the heat insulation component 6. The diameter of the seal 14 is larger than the diameter of the top opening of the accommodating groove of the frame 1. That is, when the measurement end of the temperature measurement unit 3 extends into the inner cavity of the carrier container 2 and contacts the heat absorption carrier, the seal 14 is in sealing fit with the top opening of the accommodating groove of the frame 1 to reduce the heat exchange between the heat absorption carrier and the external environment, and avoid the heat absorption carrier from dissipating heat outward through the top opening of the accommodating groove of the frame 1 when the stirring part 12 stirs the heat absorption carrier and the first temperature sensor 13 measures the temperature of the heat absorption carrier, effectively improving the measurement accuracy of the output heat energy and electrothermal efficiency of the energy treatment device 5.

[0054] Preferably, in one embodiment, the carrier container 2 is made of a material with high thermal conductivity, such as a copper metal material. Theoretically, when the energy treatment device 5 releases heat to the heat absorption carrier, the carrier container 2 can quickly absorb heat, and the heat absorption carrier and the carrier container 2 keep synchronous temperature changes.

[0055] In another embodiment, a plurality of second temperature sensors 15 are further provided, and the second temperature sensors 15 are evenly circumferentially arranged on the outer wall surface of the carrier container 2 for detecting the temperature of the carrier container 2.

[0056] That is, if the heating time is short, or the heat absorption carrier cannot change its temperature synchronously with the carrier container 2, when the energy treatment device 5 releases heat to the heat absorption carrier, since the carrier container 2 itself will absorb the heat in the heat absorption carrier, the heat energy absorbed by the carrier container 2 is calculated separately based on the temperature difference of the carrier container 2 before and after the temperature change through the second temperature sensor 15, and further calculate the total heat energy jointly absorbed by the carrier container 2 and the heat absorption carrier, thereby obtaining the output heat energy and electrothermal efficiency of the energy treatment device 5, improving the measurement accuracy of the output heat energy and electrothermal efficiency of the energy treatment device 5. Specifically, the calculation method of the heat absorbed by the carrier container 2 made of a high thermal conductivity material is as follows: Q 4 =C*m 3 *T Wherein, C is the specific heat capacity of the carrier container 2, m 3 is the mass of the carrier container 2, and T is the temperature difference of the carrier container 2 before and after the temperature change.

[0057] In another embodiment, the carrier container 2 can also be made of a low thermal conductivity material, then it is defaulted that the carrier container 2 itself does not absorb the heat in the heat absorption carrier. In this embodiment, when finally calculating the electrothermal efficiency of the energy treatment device 5, it is not necessary to calculate the heat absorbed by the carrier container 2 from the heat absorption carrier.

[0058] Second Embodiment Based on the same concept, referring to Figure 5 , the present invention also provides a method for measuring the output heat energy and electrothermal efficiency of an energy treatment device, which is applied to the device for measuring the output heat energy and electrothermal efficiency of an energy treatment device described in any one of the first embodiments, and includes the following steps: S1: Inject a heat absorption carrier into the carrier container 2, and the weighing platform 11 measures the total mass of the carrier container 2, the heat insulation component 6 and the heat absorption carrier contained in the carrier container 2, and subtracts the mass of the carrier container 2 and the heat insulation component 6 to automatically output the mass m of the heat absorption carrier; S2: Enable the driving component 4 to drive several first temperature sensors 13 of the temperature measuring unit 3 to move into the inner cavity of the carrier container 2, and immerse several first temperature sensors 13 in the heat absorption carrier to measure the first temperature value T 1 ; S3: After completing the first temperature value T 1After the measurement operation, enable the drive assembly 4 to drive the temperature measurement unit 3 out of the inner chamber of the carrier container 2, and drive the output end of the energy treatment instrument 5 to move into the inner chamber of the carrier container 2, so that the output end of the energy treatment instrument 5 is immersed in the heat absorption carrier. Subsequently, control the energy treatment instrument 5 to release heat to the heat absorption carrier, and maintain for a preset time t, and the power acquisition unit acquires the effective voltage U and the effective current I of the energy treatment instrument 5 within the preset time t. S4: After completing the operation of the energy treatment instrument 5 to output heat, enable the drive assembly 4 to drive the energy treatment instrument 5 out of the inner chamber of the carrier container 2, and re-drive several first temperature sensors 13 and the stirring part 12 of the temperature measurement unit 3 to move into the inner chamber of the carrier container 2, so that the several first temperature sensors 13 and the stirring part 12 are immersed in the heat absorption carrier, control the stirring part 12 to fully stir the heat absorption carrier, and when the several first temperature sensors 13 measure that the temperatures of each liquid layer of the heat absorption carrier are the same, the stirring part 12 stops stirring, and the first temperature sensor 13 measures the second temperature value T of the heat absorption carrier. 2 ; S5: In the calculation module of the electrothermal efficiency measurement device, automatically calculate the thermal energy Q absorbed by the heat absorption carrier. 1 The calculation method is: Q 1 =c*m*(T 2 -T 1 ) Where c is the specific heat capacity of the heat absorption carrier; Then, calculate the total output electrical energy Q of the energy treatment instrument 5. 2 The calculation method is: Q 2 =U*I*t; S6: Restore the measurement device and the heat absorption carrier to the initial state. The initial state of the heat absorption carrier means that the heat absorption carrier with the same mass and the same initial temperature as in the previous measurement process is re-injected into the carrier container 2. Then, enable the high-resistance stirring shaft to heat the heat absorption carrier with a preset output heat, or use the hydrated exothermic substance to heat the heat absorption carrier with a preset output heat, so that the heat absorption carrier is heated to the preset temperature. Subsequently, simulate the working conditions of the heat exchange between the heat absorption carrier and the external environment during the operation of S1-S5 of the measurement device, such as the temperature measurement unit 3 and the energy treatment instrument 5 moving into and out of the carrier container 2 successively, and the carrier container 2 absorbing heat from the heat absorption carrier, etc. Finally, based on the difference between the actual heat absorbed by the heat absorption carrier and the heat output by the stirring shaft or the hydrated exothermic substance, obtain the dissipated heat Q of the heat absorption carrier. 3 ; Among them, the dissipated heat Q of the heat absorption carrier 3It includes both the heat absorbed by the carrier container 2 from the heat absorption carrier and the heat lost by the heat absorption carrier through heat exchange with the external environment through the top opening of the carrier container 2.

[0059] Then, calculate the actual output thermal energy Q of the energy treatment device 4 , and the calculation method is: Q 4 =Q 1 +Q 3 That is, the sum of the heat actually absorbed by the heat absorption carrier, the heat absorbed by the carrier container 2, and the heat lost by the heat absorption carrier through heat exchange with the external environment.

[0060] Finally, calculate the electrothermal efficiency η of the energy treatment device 5, and the calculation method is: η = Q 4 / Q 2 *100% = (Q 1 +Q 3 ) / Q 2 *100% In summary, this embodiment provides a method for measuring the output thermal energy and electrothermal efficiency of an energy treatment device 5. The measuring device is provided with a carrier container 2, a driving component 4 and a temperature measuring unit 3, and the energy treatment device 5 to be measured is detachably installed on the driving component 4. During the measurement process, the electrothermal efficiency measuring device operates automatically, moves the temperature measuring unit 3 into the carrier container 2 to contact the heat absorption carrier, and measures the temperature parameters of the heat absorption carrier before and after heating respectively. At the same time, the energy treatment device 5 is moved into the carrier container 2 to contact the heat absorption carrier to release heat to the heat absorption carrier. By obtaining the absorbed heat of the heat absorption carrier and the total output electric energy of the energy treatment device 5, the measuring device automatically calculates and generates the output thermal energy and electrothermal efficiency of the energy treatment device 5. Through this embodiment, the measurement efficiency of the output thermal energy and electrothermal efficiency of the energy treatment device 5 can be effectively improved, automatic operation can be realized, and by controlling the experimental variables, the accuracy of the measurement results can be effectively guaranteed.
