[0028] It is difficult for existing in vitro organ preservation apparatuses to control the perfusion temperature of the constant-temperature in vitro organ preservation apparatuses in a low-power working state, which limits the battery life of the in vitro organ preservation apparatuses.

[0029] Based on the above reasons, an embodiment of the present application provides a low-power temperature control method for an in vitro organ preservation instrument, the method comprising: obtaining historical medium temperature values ​​of a heat-conducting medium in time series, historical medium flow values ​​of the heat-conducting medium in time series, and historical solution temperature values ​​of a perfusion solution in time series; wherein the heat-conducting medium is used to be transported to a heat-conducting tube in a perfusion solution to conduct heat and control the temperature of the perfusion solution, and the perfusion solution is used to perfuse an in vitro organ; through a time-series solution temperature control model, the time-series medium flow value of the heat-conducting medium transported to the perfusion solution for heat and temperature control is determined according to the historical medium temperature values, the historical medium flow values, and the historical solution temperature values; when the current medium temperature value in the time-series medium temperature values ​​is greater than or equal to the preset maximum medium temperature value, the temperature regulating component is driven by a compressor to cool the heat-conducting medium. When the low-power temperature control method of the in vitro organ preservation instrument in the embodiment of the present application is working, the perfusion solution is thermally conductively controlled in the heat-conducting tube through the heat-conducting medium, and the flow rate of the heat-conducting medium is controlled to achieve precise control of the temperature of the perfusion solution. Only when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset maximum medium temperature value, the compressor drives the temperature adjustment component to cool the heat-conducting medium, thereby avoiding frequent startup and shutdown of the compressor, and achieving the purpose of low-power control of the perfusion solution temperature.

[0030] In some scenarios, a low-power temperature control method for an in vitro organ preservation apparatus according to an embodiment of the present application can be applied to the temperature control of the perfusion solution of the in vitro organ preservation apparatus. It can accurately control the temperature of the perfusion solution of the in vitro organ preservation apparatus, reduce the energy consumption of the temperature control of the perfusion solution of the in vitro organ preservation apparatus, and improve the battery life of the in vitro organ preservation apparatus.

[0031] The following is a detailed description of a low-power temperature control method for an in vitro organ preservation apparatus provided in an embodiment of the present application with reference to specific examples.

[0032] Figure 1 A schematic flow chart of a low-power temperature control method for an in vitro organ preservation apparatus provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes S110 to S130, and S110 to S130 are described in detail below.

[0033] S110, obtaining the historical medium temperature value of the heat-conducting medium in time series, the historical medium flow value of the heat-conducting medium in time series, and the historical solution temperature value of the perfusion solution in time series. The heat-conducting medium is used to be transported to the heat-conducting pipe in the perfusion solution to conduct heat and control the temperature of the perfusion solution, and the perfusion solution is used to perfuse the isolated organ.

[0034] Figure 2A schematic diagram of the workflow of a low-power temperature control method for an in vitro organ preservation apparatus provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, when the low-power temperature control method of the in vitro organ preservation instrument in the embodiment of the present application is working, the structure of the in vitro organ preservation instrument may include a heat-conducting medium chamber for accommodating a heat-conducting medium, and a perfusion solution chamber for accommodating a perfusion solution. A sealed heat-conducting pipe is provided in the perfusion solution chamber, and the heat-conducting pipe is used to circulate the heat-conducting medium. The heat-conducting medium can then exchange heat with the perfusion solution in the heat-conducting pipe to achieve temperature control of the perfusion solution. The perfusion solution is used to perfuse the in vitro organ.

[0035] When controlling the temperature of the perfusion solution, the heat transfer medium can be transported to the heat transfer tube in the perfusion solution through a micro flow pump to conduct heat and control the temperature of the perfusion solution. The power of the micro flow pump is much lower than the power of the compressor. Continuous temperature control of the perfusion solution by the micro flow pump can greatly reduce the energy consumption of temperature control of the perfusion solution.

[0036] It should be noted that when the in vitro organ preservation apparatus is working, it is also necessary to cooperate with other control components that control the parameters of the perfusion solution (such as pH value), which will not be described in detail in the embodiments of the present application.

[0037] When the temperature of the perfusion solution is controlled, the historical medium temperature value of the heat-conducting medium in time series, the historical medium flow value of the heat-conducting medium in time series and the historical solution temperature value of the perfusion solution in time series can be obtained, and then the temperature of the perfusion solution can be controlled according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value.

[0038] For example, the historical medium temperature value may be a time-series medium temperature value of the heat-conducting medium within 30 minutes from the current moment.

[0039] For example, the historical medium flow value of the heat-conducting medium in time series may be the transport flow value of the heat-conducting medium in time series from the current moment to 30 minutes.

[0040] For example, the time-series historical solution temperature values ​​of the perfusion solution may be time-series temperature values ​​of the perfusion solution within 30 minutes from the current moment.

[0041] S120. Determine the time-series medium flow value for heat transfer and temperature control of the heat transfer medium to the perfusion solution according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value through the time-series solution temperature control model.

[0042] Figure 3 A schematic diagram of a temperature control workflow of a low-power temperature control method for an in vitro organ preservation apparatus provided in an embodiment of the present application is shown in FIG. Figure 3As shown, when the temperature of the perfusion solution is controlled according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value, the time-series solution temperature control model can be used to determine the time-series medium flow value for heat transfer and temperature control of the heat transfer medium transported to the perfusion solution according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value, and then the flow rate of the heat transfer medium can be controlled by the time-series medium flow value, and then the temperature of the perfusion solution can be controlled by the flow rate of the heat transfer medium.

[0043] Exemplarily, the time-series solution temperature control model may be a LSTM-based deep learning model.

[0044] For example, the time-series medium flow rate value may be a time-series medium flow rate value of the heat-conducting medium delivered to the perfusion solution for heat conduction and temperature control within 5 minutes starting from the current moment.

[0045] S130: When the current medium temperature value in the sequential medium temperature values ​​is greater than or equal to the preset maximum medium temperature value, the temperature regulating component is driven by a compressor to cool the heat transfer medium.

[0046] In the process of controlling the temperature of the perfusion solution, when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset maximum medium temperature value, it means that the temperature of the heat-conducting medium is too high, which may affect the temperature control effect of the perfusion solution. Then, the heat-conducting medium can be cooled by driving the temperature regulating component through the compressor, which can avoid frequent starting and shutting down of the compressor to control the temperature of the perfusion solution and reduce the energy consumption of the compressor.

[0047] Exemplarily, when the heat transfer medium is cooled by a compressor driving a temperature adjustment component, the temperature adjustment component can be driven by a compressor for refrigeration. The temperature adjustment component involves thermodynamic steps such as compression, condensation, expansion and evaporation, thereby being able to cool the heat transfer medium.

[0048] The beneficial effect brought about by the above-mentioned implementation method is that the heat-conducting medium is transported to the heat-conducting tube in the perfusion solution through a micro-flow pump to conduct heat and control the temperature of the perfusion solution, thereby realizing temperature control of the perfusion solution. The time-series solution temperature control model determines the time-series medium flow value for heat conduction and temperature control of the heat-conducting medium transported to the perfusion solution according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value, thereby realizing precise control of the temperature of the perfusion solution.

[0049] The beneficial effect brought about by the above-mentioned implementation method is that only when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset maximum medium temperature value, the compressor is started to cool the heat transfer medium, and by reducing the operating cycle of the compressor, unnecessary startup and shutdown are prevented, thereby significantly reducing the energy consumption of temperature control of the perfusion solution.

[0050] In some implementations, in the above S130, when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset maximum medium temperature value, the compressor drives the temperature adjustment component to cool the heat-conducting medium, including: when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset first medium temperature value, the compressor is started to cool the heat-conducting medium with a first power value. When the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset second medium temperature value, the compressor is started to cool the heat-conducting medium with a second power value. Wherein, the first medium temperature value is less than the second medium temperature value, and the first power value is less than the second power value.

[0051] When performing temperature control, when the current medium temperature value in the sequence of medium temperature values ​​is greater than or equal to the preset first medium temperature value, the compressor can be started to cool the heat-conducting medium with the first power value; when the current medium temperature value in the sequence of medium temperature values ​​is greater than or equal to the preset second medium temperature value, the compressor can be started to cool the heat-conducting medium with the second power value, and the first medium temperature value is less than the second medium temperature value, and the first power value is less than the second power value, so that the power of the compressor can be dynamically adjusted according to the range of the medium temperature value, thereby achieving the purpose of dynamically adjusting the compressor power according to the range of the medium temperature value, and further realizing the energy consumption control of the temperature control process.

[0052] Exemplarily, the first medium temperature value may be 2°C, and the second medium temperature value may be 4°C.

[0053] Exemplarily, the first power value may be 50W, and the second power value may be 100W.

[0054] The beneficial effect brought about by the above implementation method is that the power of the compressor can be dynamically adjusted according to the range of the medium temperature value, thereby achieving precise control of the compressor power and further reducing energy consumption.

[0055] The beneficial effect brought about by the above-mentioned implementation method is that the higher the current medium temperature value, the greater the power of the compressor, which can increase the speed of adjusting the temperature reduction of the heat transfer medium, increase the speed of controlling the temperature of the heat transfer medium, and improve the temperature control effect of the in vitro organ preservation environment.

[0056] In some implementations, in the above S130, when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset maximum medium temperature value, the compressor drives the temperature adjustment component to cool the heat-conducting medium, including: when the total volume of the heat-conducting medium is less than the preset total volume, and when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset first medium temperature value, the compressor is started to cool the heat-conducting medium with a first power value. When the total volume of the heat-conducting medium is greater than or equal to the preset total volume, and when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset second medium temperature value, the compressor is started to cool the heat-conducting medium with a second power value.

[0057] When the temperature of the heat-conducting medium is controlled, when the temperature of heat-conducting medium of different volumes is controlled, when the total volume of the heat-conducting medium is less than the preset total volume, it means that the volume of the heat-conducting medium is small, and when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset first medium temperature value, the compressor can be started to cool the heat-conducting medium with a first power value, so as to achieve a smaller power value to control the temperature of the heat-conducting medium, which can reduce the temperature adjustment speed of the heat-conducting medium with a total volume less than the preset value.

[0058] When the temperature of heat-conducting media of different volumes is controlled, when the total volume of the heat-conducting medium is greater than or equal to the preset total volume, it means that the volume of the heat-conducting medium is large, and when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset second medium temperature value, the compressor is started to cool the heat-conducting medium with the second power value, so as to achieve a larger power value to control the temperature of the heat-conducting medium, which can increase the temperature adjustment speed of the heat-conducting medium greater than or equal to the preset total volume.

[0059] Exemplarily, the total volume of the heat-conducting medium may be the same as the volume of the heat-conducting medium containing cavity for containing the heat-conducting medium, and the heat-conducting medium containing cavities of different specifications of in vitro organ preservation instruments may be different.

[0060] For example, the total volume of the heat-conducting medium may be adjusted during use, and the heat-conducting medium cavity may be filled with heat-conducting medium of different volumes.

[0061] The beneficial effect brought about by the above-mentioned implementation method is that the temperature control power of the heat-conducting medium is controlled according to the total volume of the heat-conducting medium. When the total volume of the heat-conducting medium is small, the temperature adjustment speed of the heat-conducting medium smaller than the preset total volume is reduced. When the total volume of the heat-conducting medium is large, the temperature adjustment speed of the heat-conducting medium smaller than the preset total volume is increased, thereby improving the stability of the temperature control of the heat-conducting medium, reducing the temperature fluctuation amplitude of the heat-conducting medium, and improving the robustness of the perfusion solution.

[0062] The beneficial effect brought about by the above implementation is that when the total volume of the heat-conducting medium is adjusted during use, the temperature fluctuation amplitude of the heat-conducting medium can be reduced, thereby improving the robustness of the temperature control of the perfusion solution.

[0063] Figure 4 A flow chart of another low-power temperature control method for an in vitro organ preservation apparatus provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, in the above S130, when the current medium temperature value in the sequential medium temperature value is greater than or equal to the preset maximum medium temperature value, the temperature regulating component is driven by the compressor to cool the heat transfer medium, including S131 to S132. S131 to S132 are specifically described below.

[0064] S131. Before the compressor drives the temperature adjustment component to cool the heat transfer medium, the ambient temperature value and the constant temperature of the perfusion solution are obtained, and the temperature difference between the ambient temperature value and the constant temperature of the perfusion solution is determined.

[0065] When the ambient temperature is different and the thermal insulation effect of the in vitro organ preservation apparatus is stable, the perfusion solution and the heat-conducting medium of the in vitro organ preservation apparatus may absorb external heat and heat up at different rates. Therefore, before the compressor drives the temperature regulating component to cool down the heat-conducting medium, the ambient temperature value and the constant temperature of the perfusion solution can be obtained, and the temperature difference between the ambient temperature value and the constant temperature of the perfusion solution can be determined. The temperature difference characterizes the heating rate of the perfusion solution and the heat-conducting medium of the in vitro organ preservation apparatus, and the temperature control speed of the heat-conducting medium can be controlled by the temperature difference.

[0066] Illustratively, the temperature difference may be 20°C, 25°C or 30°C.

[0067] S132: Determine, according to the temperature difference, a target temperature value for cooling the heat transfer medium by driving the temperature adjustment component through the compressor.

[0068] When the perfusion solution and the heat transfer medium of the in vitro organ preservation apparatus absorb external heat at different speeds of heating, in order to reduce the number of start-stop cycles of the compressor, the target temperature value for cooling the heat transfer medium by driving the temperature regulating component by the compressor can be determined based on the temperature difference, and then the heat transfer medium can be controlled to cool to the target temperature value through the operation of the compressor.

[0069] For example, when the temperature difference is 20°C, the heat transfer medium can be controlled to cool down to a target temperature of 20°C; when the temperature difference is 30°C, the heat transfer medium can be controlled to cool down to a target temperature of 10°C.

[0070] The beneficial effect brought about by the above-mentioned implementation method is that when different ambient temperatures cause the perfusion solution and the heat-conducting medium of the in vitro organ preservation instrument to absorb external heat and heat up at different rates, different target temperature values ​​for cooling the heat-conducting medium by driving the temperature regulating component through the compressor can be determined, which can reduce the number of start and stop cycles of the compressor, and can further reduce the number of start and stop times of the compressor and further reduce energy consumption.

[0071] In some implementations, in the above S132, according to the temperature difference, determining the target temperature value for cooling the heat transfer medium by driving the temperature adjustment component by the compressor includes: when the temperature difference increases by a first temperature value, the target temperature value correspondingly decreases by a ratio of the first temperature value to the volume coefficient. The volume coefficient represents the total volume of the heat transfer medium.

[0072] When the temperature difference between the ambient temperature value and the constant temperature of the perfusion solution is different, and different target temperature values ​​for cooling the heat transfer medium by driving the temperature adjustment component by the compressor are determined, the target temperature value can be correspondingly reduced by the ratio of the first temperature value to the volume coefficient every time the temperature difference increases by the first temperature value, and then the heat transfer medium is controlled to be lowered to a lower temperature when the temperature difference is larger, thereby effectively reducing the number of cooling times of the heat transfer medium, effectively reducing the number of starts and stops of the compressor and further reducing energy consumption.

[0073] During operation, the volume coefficient represents the total volume of the heat-conducting medium, and the target temperature value for cooling the heat-conducting medium can be controlled by the volume coefficient. When the total volume of the heat-conducting medium is larger, the temperature reduction range of the target temperature value can be reduced; when the total volume of the heat-conducting medium is smaller, the temperature reduction range of the target temperature value can be increased.

[0074] The beneficial effect brought about by the above implementation method is that when the temperature difference is larger, the heat transfer medium is controlled to be lowered to a lower temperature, which can reduce the number of starts and stops of the compressor and further reduce energy consumption.

[0075] The beneficial effect brought about by the above-mentioned implementation method is that when the total volume of the heat-conducting medium is larger, the temperature reduction range of the target temperature value can be reduced; when the total volume of the heat-conducting medium is smaller, the temperature reduction range of the target temperature value can be increased, thereby ensuring that the specific heat capacity of the heat-conducting medium is in a stable state, and ensuring the temperature control effect of the perfusion solution through the heat-conducting medium.

[0076] The beneficial effect brought about by the above implementation method is that it can ensure that the working time interval of the compressor is moderate, can avoid the compressor from working for a long time, and improve the protection effect of the compressor.

[0077] In some implementations, the above method further includes: obtaining an ambient temperature value, and when the current medium temperature value in the sequential medium temperature value is less than a preset minimum medium temperature value, and when the ambient temperature value is greater than or equal to the preset ambient temperature value, heating the heat-conducting medium by using the heat energy in the environment through the heating module. When the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is less than the preset ambient temperature value, heating the heat-conducting medium through the heating component.

[0078] In some cases, it is also necessary to heat the perfusion solution to control the temperature. The embodiment of the present application can use the thermal energy in the environment to heat the perfusion solution.

[0079] When the perfusion solution is heated, the ambient temperature value can be obtained. When the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is greater than or equal to the preset ambient temperature value, it means that the current medium temperature value is low and the heat-conducting medium needs to be heated, and the ambient temperature value is high. Then, the heat-conducting medium can be heated by the heat energy in the environment through the heating module, so as to gradually heat the heat-conducting medium by utilizing the heat energy in the environment.

[0080] Exemplarily, when obtaining the ambient temperature value, the temperature value in the environment may be obtained through a temperature sensor.

[0081] For example, when the heat conducting medium is heated by utilizing the heat energy in the environment through the temperature increasing module, the heat conducting medium can be heated by guiding the airflow in the environment through the fan.

[0082] For example, when the heat-conducting medium is heated by utilizing the heat energy in the environment through the temperature-increasing module, the heat in the external environment can also be conducted through the heat-conducting pipe to exchange heat with the heat-conducting medium, so as to heat the heat-conducting medium.

[0083] When the perfusion solution is heated, when the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is less than the preset ambient temperature value, it means that the ambient temperature is too low and the heat-conducting medium cannot be heated by the heat in the environment. At this time, the heat-conducting medium can be heated by the heating component.

[0084] It should be noted that the minimum medium temperature value may be the lower limit temperature value for temperature control of the perfusion solution, and the minimum medium temperature value is not necessarily the lower limit temperature value of the perfusion solution.

[0085] Exemplarily, the minimum medium temperature value may be -2 to 0°C.

[0086] Exemplarily, the heating component may be an electric heating tube disposed in the heat-conducting medium cavity.

[0087] For example, when the heat-conducting medium is heated by the temperature-increasing module using the heat energy in the environment, the heat-conducting medium can exchange heat with the airflow in the environment through the heat-conducting fins, thereby achieving temperature control of the heat-conducting medium.

[0088] The beneficial effect brought about by the above-mentioned implementation method is that when the ambient temperature value is greater than or equal to the preset ambient temperature value, the heat in the environment is used to heat the heat-conducting medium, thereby reducing the energy consumption of the preservation instrument; when the ambient temperature value is less than the preset ambient temperature value, the heat-conducting medium is heated by the heating component, and the temperature of the heat-conducting medium can be controlled in time by using electrical energy.

[0089] The beneficial effect brought about by the above implementation is that the heating component does not directly heat the perfusion solution, which can avoid local overheating and deterioration of the perfusion solution, thereby ensuring the effect of the perfusion solution during use.

[0090] In some implementations, the above method further includes: obtaining an ambient temperature value, and when the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is greater than or equal to the preset first ambient temperature value, heating the heat-conducting medium by using the heat energy in the environment through the heating module. When the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is less than the first ambient temperature value and greater than or equal to the preset second ambient temperature value, heating the heat-conducting medium by using the heat energy in the environment through the heating module, and heating the heat-conducting medium through the heating component. When the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is less than the preset second ambient temperature value, heating the heat-conducting medium through the heating component. Wherein, the first ambient temperature value is greater than the second ambient temperature value.

[0091] When the temperature of the heat-conducting medium is controlled, the ambient temperature value can be obtained. When the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is greater than or equal to the preset first ambient temperature value, the heat-conducting medium is heated by the heating module using the heat energy in the environment. The first ambient temperature value corresponds to the ambient temperature threshold for heating the heat-conducting medium only by using the heat energy in the environment through the heating module.

[0092] When the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is less than the first ambient temperature value and greater than or equal to the preset second ambient temperature value, the heat conducting medium is heated by the heating module using the heat energy in the environment, and the heat conducting medium is heated by the heating component. At this time, the heat conducting medium can be heated by the heat energy in the environment and the heating component. When the total volume of the heat conducting medium is large, the temperature control of the heating medium can be achieved with the lowest energy consumption.

[0093] When the current medium temperature value in the sequential medium temperature value is less than the preset minimum medium temperature value, and when the ambient temperature value is less than the preset second ambient temperature value, it means that the ambient temperature is too low, and the heat-conducting medium can be heated by the heating component to ensure the heating effect of the heat-conducting medium, wherein the first ambient temperature value is greater than the second ambient temperature value.

[0094] The beneficial effect brought about by the above-mentioned implementation method is that when the ambient temperature value is in different temperature ranges, the temperature of the thermally conductive medium can be controlled by using the heat in the environment to heat the thermally conductive medium, the heat in the environment and the heating component to heat the thermally conductive medium together, or the heating component alone to heat the thermally conductive medium, thereby achieving the minimum energy consumption for heating the thermally conductive medium and improving the control effect of reducing the energy consumption of the in vitro organ preservation device.

[0095] The beneficial effect brought about by the above implementation method is that when the heat transfer medium is heated by the heat energy in the environment and the heating component, when the total volume of the heat transfer medium is large, the temperature rise control of the heating medium can be achieved with the lowest energy consumption.

[0096] In some implementations, the above method also includes: when the current medium flow value in the historical medium flow value is greater than or equal to the preset medium flow value, the sequential medium temperature value is determined according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value through the sequential medium temperature control model, and the temperature of the heat-conducting medium is controlled according to the sequential medium temperature value to reduce the sequential medium flow value of the heat-conducting medium delivered to the perfusion solution for thermal temperature control to less than the preset medium flow value.

[0097] When the energy consumption of the in vitro organ preservation apparatus is controlled, the medium flow value of the heat transfer medium pumping can also be controlled to reduce the power consumption of the flow pump used to pump the heat transfer medium.

[0098] When the current medium flow value in the historical medium flow value is greater than or equal to the preset medium flow value, it means that the current medium flow value is too large. The sequential medium temperature value can be determined according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value through the sequential medium temperature control model, and the temperature of the heat-conducting medium can be controlled according to the sequential medium temperature value to reduce the sequential medium flow value of the heat-conducting medium transported to the perfusion solution for thermal temperature control to less than the preset medium flow, thereby achieving effective control of the flow of the heat-conducting medium. Among them, the sequential medium flow value to less than the preset medium flow means that the medium flow values ​​at multiple moments in the sequential medium flow value gradually decrease to less than the preset medium flow.

[0099] During operation, after controlling the temperature of the heat-conducting medium according to the sequential medium temperature value, the temperature of the heat-conducting medium is reduced, and then the sequential medium flow value of the heat-conducting medium delivered to the perfusion solution for heat conduction and temperature control can be correspondingly reduced.

[0100] Exemplarily, the sequential medium temperature control model may be a LSTM-based deep learning model.

[0101] Exemplarily, the sequential medium temperature value may be a sequential medium temperature value that reduces the temperature of the heat-conducting medium.

[0102] The beneficial effect brought about by the above-mentioned implementation method is that when the power consumption of the flow pump used to pump the heat-conducting medium is too large, the temperature of the heat-conducting medium is controlled according to the sequential medium temperature value to reduce the sequential medium flow value of the heat-conducting medium transported to the perfusion solution for thermal temperature control to less than the preset medium flow rate, which can reduce the energy consumption of pumping the heat-conducting medium and improve the effect of the in vitro organ preservation instrument.

[0103] Figure 5 A schematic diagram of the logical structure of a low-power temperature control system of an in vitro organ preservation device provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, an embodiment of the present application also provides a low-power temperature control system for an in vitro organ preservation instrument, which adopts the above-mentioned low-power temperature control method for an in vitro organ preservation instrument.

[0104] like Figure 5 As shown, the temperature measurement unit 1 is used to obtain the historical medium temperature value of the heat-conducting medium in time series, the historical medium flow value of the heat-conducting medium in time series, and the historical solution temperature value of the perfusion solution in time series. The medium flow control unit 2 is used to determine the time series medium flow value of the heat-conducting medium delivered to the perfusion solution for heat conduction and temperature control according to the historical medium temperature value, the historical medium flow value, and the historical solution temperature value through the time series solution temperature control model. The temperature reduction control unit 3 is used to drive the temperature adjustment component to reduce the temperature of the heat-conducting medium through the compressor when the current medium temperature value in the time series medium temperature value is greater than or equal to the preset maximum medium temperature value.

[0105] When the low-power temperature control system of the in vitro organ preservation apparatus in the embodiment of the present application is in operation, the temperature measurement unit 1, the medium flow control unit 2 and the cooling control unit 3 cooperate with each other to achieve temperature control of the low-energy perfusion solution of the in vitro organ preservation apparatus.

[0106] The beneficial effect brought about by the above-mentioned implementation method is that the heat-conducting medium is transported to the heat-conducting tube in the perfusion solution through a micro-flow pump to conduct heat and control the temperature of the perfusion solution, thereby realizing temperature control of the perfusion solution. The time-series solution temperature control model determines the time-series medium flow value for heat conduction and temperature control of the heat-conducting medium transported to the perfusion solution according to the historical medium temperature value, the historical medium flow value and the historical solution temperature value, thereby realizing precise control of the temperature of the perfusion solution.

[0107] In some implementations, the low-power temperature control system of the above-mentioned in vitro organ preservation instrument also includes: a temperature increase control unit 4, which is used to control the temperature increase module to use the heat energy in the environment to heat the heat transfer medium and heat the heat transfer medium through the heating component.

[0108] like Figure 5 As shown, the low-power temperature control system of the in vitro organ preservation instrument in the embodiment of the present application also includes a temperature increase control unit 4, which is used to control the temperature increase module to utilize the heat energy in the environment to heat the heat-conducting medium and to heat the heat-conducting medium through the heating component.

[0109] The beneficial effect brought about by the above-mentioned implementation method is that when the ambient temperature is high, the heat in the environment is used to heat the heat-conducting medium, thereby reducing the energy consumption of the preservation instrument; when the ambient temperature value is lower than the preset ambient temperature value, the heat-conducting medium is heated by the heating component, and the temperature of the heat-conducting medium can be controlled in time by using electrical energy.
