Abstract
Description
Technical Field
[0001] This invention relates to the field of temperature control technology for medical devices, and in particular to a high-precision temperature control method for medical devices. Background Technology
[0002] In medical device testing, liquid-based cell or tissue testing generally has high temperature requirements. The testing environment directly affects cell activity and the application effect of medical devices. Currently, existing medical testing equipment generally lacks temperature control or has low temperature control accuracy and low temperature control range stability, which cannot provide a precise temperature operating environment for pathological testing. This has brought many difficulties to medical diagnosis and medical technology advancement.
[0003] Medical heating devices, also known as medical heating blankets, are typically used during surgery to maintain patient body temperature and prevent a rapid drop in body temperature. The core components of a medical heating device include a heating block, a fan, an air duct, an inflatable heating blanket, and a control system. The control system controls the fan to blow air heated by the heating device through the air duct into the inflatable heating blanket. The surface of the inflatable heating blanket has ventilation holes to dissipate the hot air onto the patient. To regulate the temperature of the heating device and prevent overheating and potential safety hazards, a temperature sensor is installed at the air outlet of the medical heating device. The control system uses the temperature sensor's readings to adjust the temperature of the heating device or shut it down if the temperature becomes too high. However, traditional medical heating devices often regulate the ambient air temperature by expelling hot air to achieve temperature control. This method of temperature control is inaccurate, cannot accurately assess the temperature around the patient, has uncontrollable gas flow, and cannot guarantee a uniform temperature around the patient. Furthermore, when the ambient temperature rises too high, the medical heating device cannot cool down in time and must stop operating to allow natural cooling.
[0004] For various medical devices, there are significant differences in the precision and capability of their cooling and heating adjustments. Some devices have high cooling precision, but their adjustment capability decreases when the temperature requirement is higher. Similarly, heating devices are not good at cooling and cannot achieve a good temperature regulation effect across the entire temperature range. Summary of the Invention
[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to provide a high-precision temperature control method for medical devices, which solves the problems of medical devices being unable to precisely control the temperature within a small range and being unable to quickly correct and control the temperature after it deviates from the set value.
[0006] According to the present invention, a high-precision temperature control method for medical devices is provided, and the specific method is as follows:
[0007] S1: A temperature control device is installed on the equipment. The temperature control device includes a cooling component and a heating component. The cooling component is connected to the compression refrigeration mechanism, and the heating component is connected to the power control module via wires. Both the compression refrigeration mechanism and the power control module are electrically connected to a control server. The control server adjusts the cooling capacity of the cooling component by controlling the cooling degree of the compression refrigeration mechanism and the flow rate of the refrigerant. The control server controls the power control module to provide different power electrical energy to the heating component to achieve the heating capacity of the heating component. The coordinated temperature control between the cooling component and the heating component achieves the cooling or heating of the equipment, thereby realizing equipment temperature control.
[0008] S2: Multiple precise electronic thermometers are installed on the inner wall of the area requiring temperature control in the equipment. Each of these electronic thermometers is connected to a control server and is assigned a number. The temperatures measured by each electronic thermometer are Q1, Q2…Qn. Calculate the average temperature Q of the temperature measuring equipment. 平 = (Q1, +Q2, ..., +Qn) / n, calculate the deviation value L = |Qi - Qn| of the temperature measured by each of the electronic thermometers. 平 | / Q 平 *100%, set the deviation discard threshold Lq;
[0009] If the deviation value L of the temperature measured by several of the electronic thermometers is greater than or equal to Lq, then these temperature values measured by the electronic thermometers are discarded, and the temperature values Q measured by the remaining electronic thermometers, whose deviation value L is less than Lq, are recounted. 平 ;
[0010] If no deviation L of the temperature measured by the electronic thermometer is greater than or equal to Lq, then Q is calculated directly using the temperatures measured by all the electronic thermometers 9. 平 value;
[0011] S3: The temperature range adjustable by the temperature control device is divided into multiple temperature control zones, and a correction coefficient η is provided in each temperature control zone. i If the temperature maintained by the equipment is set to T, then the deviation rate of the temperature in the temperature-controlled area of the equipment is γ = |Q 平 -T| / T*100%, if γ is less than η i When γ is greater than or equal to η, no temperature adjustment is needed. i When this happens, temperature adjustment is required, where Q 平 When Q is greater than T, cooling components are used for temperature regulation. 平 When the temperature is less than T, the heating element is used to regulate the temperature.
[0012] In some embodiments of the present invention, the temperature control device includes a heat-conducting plate, a heat insulation layer, a cooling component, and a heating component. The inner sidewall of the heat-conducting plate is attached to the outer sidewall of the area of the device that needs temperature control. The cooling component and the heating component are embedded in the outer sidewall of the heat-conducting plate at intervals. A heat insulation layer is covered on the outer sidewall of the heat-conducting plate to prevent heat from being transferred outward from the heat-conducting plate.
[0013] The cooling assembly includes a first heat transfer plate, an S-shaped bend pipe, and a reverse connector. The first heat transfer plate covers the S-shaped bend pipe. A reverse connector is connected to the output end of the S-shaped bend pipe. The reverse connector extends from the upper surface of the insulation layer to the input end of the S-shaped bend pipe. The output ends of all the S-shaped bend pipes on the cooling assembly are connected to the liquid supply main pipe. One end of all the reverse connectors is connected to the liquid return main pipe. The liquid outlet and liquid inlet of the compression refrigeration mechanism are respectively connected to the liquid supply main pipe and the liquid return main pipe through pipes.
[0014] The heating assembly includes a second heat transfer plate and multiple heating strips arranged at equal intervals within the second heat transfer plate. The heating strips are connected in series and the positive and negative poles at both ends of the heating strips are connected to the power control module.
[0015] The cold liquid prepared by the compression refrigeration mechanism flows in the S-shaped bend pipes on each cooling component to cool all the first heat transfer plates, thereby achieving the purpose of cooling the heat conduction plates.
[0016] The power control module provides electrical energy of varying power to heat the heating bars of each heating component, thereby raising the temperature of all the second heat transfer plates and achieving the purpose of heating the heat conduction plate.
[0017] In other embodiments of the present invention, the compression refrigeration mechanism includes a refrigeration compressor, a first water tank, and a second water tank. The liquid outlet of the refrigeration compressor is connected to the first water tank near the top via a pipe. The first water tank is connected to the main liquid supply pipe near the bottom via a pipe, and a first flow pump is installed in the pipe.

The second water tank is connected to the refrigeration compressor inlet port near the bottom via a pipe, and a second flow pump is installed in the pipe.
[0018] In other embodiments of the present invention, the temperature control zones of different devices are divided differently, and the difference between the highest and lowest temperatures in multiple temperature control zones of the same device is also different.
[0019] In other embodiments of the present invention, if the number of electronic thermometers whose measured temperature deviation L is greater than or equal to Lq is large, resulting in fewer than 3 remaining electronic thermometers whose measured temperature deviation L is less than Lq, another calculation of Q will be initiated.平 The method involves analyzing all temperature values measured by the electronic thermometers, identifying the three values with the smallest deviation from the previous measurement, and then calculating the average Q of these three values. 平 .
[0020] In other embodiments of the present invention, the interval between temperature measurements by the electronic thermometers corresponding to the multiple temperature control zones of the same device is different, and the η values corresponding to the multiple temperature control zones are... i The smaller the value, the shorter the temperature measurement interval of the electronic thermometer.
[0021] In other embodiments of the present invention, the temperature adjustment speed of the cooling component and the heating component is set according to the deviation rate γ, i.e., (γ-ηi) / η i The higher the value, the faster the temperature needs to be adjusted.
[0022] In other embodiments of the present invention, the device is a refrigeration device or a human body warming device.
[0023] In other embodiments of the present invention, the temperature deviation within the temperature control area of the temperature control device is less than 1°C.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0033] like Figure 1-5 As shown, the present invention proposes a high-precision temperature control method for medical devices, the specific method of which is as follows:
[0034] S1: A temperature control device is installed on the equipment. The temperature control device includes a cooling component and a heating component. The cooling component is connected to the compression refrigeration mechanism, and the heating component is connected to the power control module via wires. Both the compression refrigeration mechanism and the power control module are electrically connected to a control server. The control server adjusts the cooling capacity of the cooling component by controlling the cooling degree of the compression refrigeration mechanism and the flow rate of the refrigerant. The control server controls the power control module to provide different power electrical energy to the heating component to achieve the heating capacity of the heating component. The coordinated temperature control between the cooling component and the heating component achieves the cooling or heating of the equipment, thereby realizing equipment temperature control.
[0035] S2: Multiple precise electronic thermometers 9 are installed on the inner wall of the area requiring temperature control in the equipment. Each of the electronic thermometers 9 is connected to a control server and is assigned a number. The temperatures measured by each electronic thermometer 9 are Q1, Q2…Qn. Calculate the average temperature Q of the temperature measuring equipment. 平 = (Q1, +Q2, ..., +Qn) / n, calculate the deviation value L = |Qi - Qn| of the measured temperature of each of the electronic thermometers 9. 平 | / Q 平*100%, set the deviation discard threshold Lq; to control the temperature of the controlled area, it is essential to accurately monitor the temperature within that area for temperature adjustment. Temperature monitoring requires precise temperature data acquisition. A single electronic thermometer is unlikely to provide accurate readings, and errors are difficult to avoid. Therefore, multiple thermometers (at least 5) should be set. After each temperature measurement, discard the values with the largest deviations and average the remaining values to more accurately determine the current temperature of the controlled area, thus facilitating subsequent temperature adjustments. The deviation discard threshold Lq is related to the temperature control accuracy; the smaller the Lq value, the higher the accuracy.
[0036] If the deviation value L of the temperature measured by several electronic thermometers 9 is greater than or equal to Lq, then these temperature values measured by the electronic thermometers 9 are discarded, and the temperature values whose deviation value L is less than Lq are recounted Q. 平 ;
[0037] If no deviation L of the temperature measured by the electronic thermometer 9 is greater than or equal to Lq, then Q is calculated directly using all the temperatures measured by the electronic thermometer 9. 平 value;
[0038] S3: The temperature range adjustable by the temperature control device is divided into multiple temperature control zones, and a correction coefficient η is provided in each temperature control zone. i If the temperature maintained by the equipment is set to T, then the deviation rate of the temperature in the temperature-controlled area of the equipment is γ = |Q 平 -T| / T*100%, if γ is less than η i When γ is greater than or equal to η, no temperature adjustment is needed. i When this happens, temperature adjustment is required, where Q 平 When Q is greater than T, cooling components are used for temperature regulation. 平 When the temperature is less than T, the heating element is used to regulate the temperature.
[0039] Some devices require minimal temperature fluctuations for the data stored in each temperature range. Setting temperature ranges allows for the application of a correction factor η in each temperature control zone. i Using the deviation rate γ and the correction coefficient η i The size comparison determines whether temperature adjustment is needed, so as to achieve different temperature control precision settings in different ranges.
[0040] The temperature control device includes a heat-conducting plate 2, a heat insulation layer 3, a cooling component, and a heating component. The inner sidewall of the heat-conducting plate 2 is attached to the outer sidewall of the area of the equipment that needs temperature control. The cooling component and the heating component are embedded in the outer sidewall of the heat-conducting plate 2 at intervals. A heat insulation layer 3 is covered on the outer sidewall of the heat-conducting plate 2 to prevent heat from being transferred outward from the heat-conducting plate 2.
[0041] The cooling assembly includes a first heat transfer plate 7, an S-shaped bend pipe 71, and a reverse connector 20. The first heat transfer plate 7 covers the S-shaped bend pipe 71. The reverse connector 20 is connected to the output end of the S-shaped bend pipe 71. The reverse connector 20 extends from the upper surface of the insulation layer 3 to the input end of the S-shaped bend pipe 71. The output ends of all the S-shaped bend pipes 71 on the cooling assembly are connected to the liquid supply main pipe 4. One end of all the reverse connectors 20 is connected to the liquid return main pipe 5. The liquid outlet and liquid inlet of the compression refrigeration mechanism are respectively connected to the liquid supply main pipe 4 and the liquid return main pipe 5 through pipes.
[0042] The heating assembly includes a second heat transfer plate 8 and a plurality of heating strips 81 arranged at equal intervals within the second heat transfer plate 8. The heating strips 81 are connected in series and the positive and negative poles at both ends of the heating strips 81 are connected to the power control module.
[0043] The cold liquid prepared by the compression refrigeration mechanism flows in the S-shaped bend pipe 71 on each cooling component to cool all the first heat transfer plates 7, thereby achieving the purpose of cooling the heat conduction plate 2.
[0044] The power control module provides electrical energy of different power to heat each heating component heating bar 81, so that all the second heat transfer plates 8 are heated, thereby achieving the purpose of heating the heat conduction plate 2.
[0045] The first heat transfer plate 7, the second heat transfer plate 8, and the S-shaped bend pipe 71 are all made of copper or other thermally conductive metals. The heating strip 81 is coated with a heat-resistant and insulating paint and is encased in the second heat transfer plate 8. It does not conduct electricity but can conduct heat.
[0046] The cold liquid inside the S-shaped curved pipe 71 will quickly absorb the heat from the first heat transfer plate 7 to achieve cooling. Since the first heat transfer plate 7 and the second heat transfer plate 8 are set at intervals, it is equivalent to the first heat transfer plate 7 and the second heat transfer plate 8 being evenly distributed inside the heat conduction plate 2. Therefore, the cooling of the first heat transfer plate 7 and the heating of the second heat transfer plate 8 are both ways to uniformly cool and heat the heat conduction plate 2.
[0047] The compression refrigeration mechanism includes a refrigeration compressor 10, a first water tank 101, and a second water tank 102. The liquid outlet of the refrigeration compressor 10 is connected to the first water tank 101 near the top via a pipe. The first water tank 101 is connected to the liquid supply main pipe 4 near the bottom via a pipe, and a first flow liquid pump 40 is installed in the pipe. The return liquid main pipe 5 is connected to the second water tank 102 near the top via a pipe. The second water tank 102 is connected to the liquid inlet port of the refrigeration compressor 10 near the bottom via a pipe, and a second flow liquid pump 103 is installed in the pipe.
[0048] The first water tank 101 and the second water tank 102 have heat preservation properties. A certain amount of cold liquid is first prepared into the first water tank 101. When cooling is required, the cold liquid can be drawn from the first water tank 101 in time for circulation and cooling, eliminating the need for temporary cooling by the refrigeration compressor 10 and solving the problem of not being able to achieve rapid cooling effect.
[0049] The first flow pump 40 can control the flow rate of the cold liquid to achieve the cooling rate (while the temperature of the cold liquid prepared by the refrigeration compressor 10 is determined according to the temperature control zone, which is generally 3-5℃ lower than the lowest temperature of the wall temperature control zone).
[0050] The second flow pump 103 is used to regulate the speed of the refrigerant liquid in the refrigeration compressor 10.
[0051] Different devices have different temperature control zones, and the difference between the highest and lowest temperatures within multiple temperature control zones of the same device also varies. Because different devices have different temperature control accuracy requirements in different temperature control zones, the temperature control zones and their ranges are set according to the device requirements.
[0052] If the number of electronic thermometers 9 whose measured temperature deviation L is greater than or equal to Lq is too large, resulting in fewer than 3 electronic thermometers 9 remaining whose measured temperature deviation L is less than Lq, then another calculation of Q will be initiated. 平 The system analyzes all temperature values measured by the electronic thermometers 9, identifies the three values with the smallest deviation from the previous temperature measurement, and calculates the average Q of these three values. 平 .
[0053] Sometimes, multiple electronic thermometers may collect temperatures greater than Lq (it cannot be guaranteed that at least three values will be usable). For example, if the second temperature collection is as follows: Q1 = 5.8, Q2 = 6.2, Q3 = 5.9, Q4 = 6.1, Q5 = 5.1, Q6 = 5.3, and Q7 = 5.6, and their average value is between 5.60 and 5.80, then Q1 = 5.8 and Q7 = 5.6 are usable. However, calculating the average value in this way is not accurate enough.
[0054] The previous temperature data were as follows: Q1 = 5.7, Q2 = 5.8, Q3 = 5.7, Q4 = 5.3, Q5 = 5.6, Q6 = 5.8 and Q7 = 5.7. The values with smaller deviations are: Q1 = 5.8, Q3 = 5.9 and Q7 = 5.6, and the calculated average values are more accurate.
[0055] The electronic thermometers 9 corresponding to multiple temperature control zones of the same device measure temperature at different intervals, and the η corresponding to multiple temperature control zones... i The smaller the value, the shorter the temperature measurement interval of the electronic thermometer 9.
[0056] For applications requiring precise temperature control and smaller temperature fluctuations, reduce the interval time and increase the frequency of temperature sampling. This is because after each sampling, if there is a temperature deviation, the temperature needs to be adjusted. Since the temperature change is small over time intervals, the temperature adjustment is more precise.
[0057] The temperature adjustment speed of the cooling and heating components is set according to the deviation rate γ, i.e., (γ-ηi) / η i The larger the value, the faster the temperature adjustment is required. The greater the deviation from the set temperature, the larger the difference between the set temperature and the set temperature, and the faster the temperature adjustment is required. However, the rapid temperature adjustment here does not increase the degree of cooling or heating, but is set according to the needs of the temperature control zone. Specifically, it is controlled by the flow rate of the cold liquid corresponding to the temperature control zone. The heating is also similar to that of the temperature control zone, only the temperature is higher than that of the temperature control zone.
[0058] The device is either a refrigeration device 1 or a human body warming device 6. The refrigeration device 1 is generally a medical device for preserving cell or tissue samples, and the human body warming device 6 is a heated medical bed.
[0059] The temperature control device adjusts the temperature deviation within the controlled area of the equipment to be less than 1℃. For some temperature-controlled areas, precise temperature control with a deviation of less than 1℃ can be achieved. For temperature-controlled medical beds, the temperature fluctuation within the bed can be guaranteed to be within 5℃, as patients have a certain ability to regulate their temperature (even when sick, they are not inanimate objects). A fluctuation within 5℃ achieves precise temperature control.
[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
