The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number, while the terms "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features, and not as indicating or implying relative importance, the number of indicated technical features, or the order of the indicated technical features.
[0045] The following problems often occur with the preservation of blood in test tubes: Blood in test tubes can be stored at room temperature for 2-4 hours. When the storage time exceeds 2-4 hours, a special storage device is required. The temperature inside the existing storage device is unstable, which can lead to hemolysis of blood cells and affect the test results.
[0046] Existing test tube incubators are not stable in controlling the temperature inside the chamber, which causes the blood in the test tubes to affect the test results due to temperature changes inside the chamber.
[0047] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a test tube constant temperature chamber that can improve the stability of temperature control within the chamber, thereby reducing the impact of temperature changes on the blood in the test tube.
[0048] Reference Figure 1 and Figure 2 , Figure 1 A schematic diagram of a test tube incubator in an embodiment of the present invention is shown. Figure 2 A block diagram of a test tube incubator according to an embodiment of the present invention is shown. In some embodiments, the test tube incubator 1 is arranged from the outside to the inside as follows: an outer shell, an insulation layer, an aluminum plate inner liner, and an inner cavity air layer. A first PT100 sensor array 101 is arranged in the inner cavity air layer, and a second PT100 sensor array 102 is arranged on the outer wall of the aluminum plate inner liner and the inner side of the insulation layer. Both the first PT100 sensor array 101 and the second PT100 sensor array 102 are connected to a controller 103. A micro-oscillating anti-condensation module is integrated inside the test tube incubator 1. The micro-oscillating anti-condensation module includes a drive motor 104, an eccentric transmission component 105, and a oscillating tray. The drive motor 104 and the eccentric transmission component 105 are arranged on the rear side of the outer shell. The output end of the drive motor 104 is connected to the eccentric transmission component 105, and the control end of the drive motor 104 is connected to the controller 103. The oscillating tray is arranged at the bottom of the test tube incubator, and the eccentric transmission component 105 is connected to the oscillating tray through a transmission shaft.
[0049] The test tube is placed on the swing tray of the micro-swing anti-coagulation module. The switch of the test tube thermostat 1 is turned on, and the target temperature inside the test tube thermostat 1 is set. The test tube thermostat 1 starts the heating device to heat the tube and starts the drive motor 104 to drive the eccentric transmission component 105 to work. The eccentric transmission component 105 drives the swing tray to rotate. At the same time, the cavity temperature inside the chamber is detected in real time by the first PT100 sensor array 101 and transmitted to the controller 103. The wall temperature is detected in real time by the second PT100 sensor array 102 and transmitted to the controller 103. The controller 103 adjusts the temperature inside the chamber in real time according to the cavity temperature and the wall temperature to keep the temperature inside the chamber at the target temperature. This can improve the stability of temperature control inside the chamber and reduce the impact of temperature changes on the blood in the test tube.
[0050] It should be noted that the chamber uses a high-density polyurethane insulation layer and a heat-dissipating aluminum plate inner liner, combined with a high-precision first PT100 sensor array, a second PT100 sensor array, and a PID temperature control algorithm to achieve stable temperature inside the chamber. The insulation layer covers the left and right sides, top, bottom, and back of the chamber. The aluminum plate inner liner is embedded in the foaming mold of the insulation layer, with its outer surface directly and tightly bonded to the insulation layer. The inner surface forms a constant-temperature cavity that is in direct contact with the air and test tube rack.
[0051] The micro-oscillating anti-coagulation module eliminates the independent oscillating mechanism for each test tube position, replacing it with a single micro-oscillating mechanism for the entire test tube rack, driven by a motor and eccentric transmission components, resulting in a simple and reliable structure. Furthermore, the test tube rack utilizes a flexible silicone cushioning base, eliminating mechanical impact during oscillation, and the oscillation trajectory is a low-amplitude circular motion, preventing violent blood sloshing.
[0052] The first PT100 sensor array has a four-wire shielded cable leading out from the suspended probe, fixed to the side wall of the aluminum inner liner along a Teflon bracket, and the cable passes through a pre-sealed cable hole in the inner liner, entering between the outer wall of the aluminum inner liner and the insulation layer. The second PT100 sensor array has its probe attached to the back of the aluminum inner liner, and the cable enters directly into the insulation layer.
[0053] The drive motor is fixed to the outer wall of the rear outer shell and the insulation layer of the enclosure, without occupying internal cavity space or generating internal heat. The drive motor's transmission shaft passes vertically through the rear wall insulation layer. The eccentric transmission component is directly locked to the drive motor shaft end. A bearing joint is installed at the outer axis of the eccentric transmission component, which is directly hinged to the outer end of the drive shaft passing through the enclosure. The transmission process includes: motor rotation → eccentric transmission component making circular motion → driving the drive shaft to make low-amplitude circular oscillation → transmitting to the bottom oscillating tray inside the enclosure.
[0054] Furthermore, in some embodiments, a stepped test tube compartment is provided on the pendulum tray, with a positioning hole at the bottom of the test tube compartment into which a silicone cushioning sleeve is embedded, and an insulated door is provided at the top of the test tube compartment. The insulated door is a flip-top type located at the top of the test tube compartment.
[0055] It should be noted that an insulation door is installed above each test tube position. The insulation door is made of aerogel or polyimide material with extremely low thermal conductivity. When taking or placing a single tube, only the insulation door at the corresponding position is opened, while the rest of the area remains sealed and insulated.
[0056] Reference Figure 3 , Figure 3 A flowchart illustrating the isothermal storage method in an embodiment of the present invention is shown. In some embodiments, the isothermal storage method of the test tube incubator is applied to the test tube incubator of any of the above embodiments, and the isothermal storage method may include, but is not limited to, steps 101 to 103:
[0057] Step 101: Obtain the temperature of the chamber of the test tube incubator in real time to obtain the chamber temperature.
[0058] Step 102: Obtain the temperature of the wall surface of the test tube constant temperature chamber in real time to obtain the wall surface temperature.
[0059] Step 103: Adjust the temperature of the test tube incubator according to the cavity temperature and wall temperature.
[0060] In steps 101 to 103 of this embodiment, the temperature of the chamber of the test tube incubator is acquired in real time through the first PT100 sensor array, and the temperature of the wall of the test tube incubator is acquired in real time through the second PT100 sensor array. Based on the chamber temperature and the wall temperature and combined with a preset composite temperature control algorithm, the temperature of the test tube incubator is adjusted. By abandoning the traditional coarse control of single-point temperature PID, a medical-grade high-precision composite temperature control algorithm is adopted, and hardware actions are matched for linkage control, ultimately reducing steady-state temperature fluctuations and transient fluctuations, and achieving the effect of rapid temperature constantness.
[0061] Reference Figure 4 , Figure 4 A flowchart illustrating the constant temperature storage method in an embodiment of the present invention is shown. In some embodiments, adjusting the temperature of the test tube incubator based on the cavity temperature and wall temperature specifically includes, but is not limited to, steps 201 to 202:
[0062] Step 201: Compare the cavity temperature with the preset target temperature to obtain the deviation temperature.
[0063] Step 202: Adjust the PID parameters of the cavity temperature according to the temperature deviation to obtain the target temperature.
[0064] In steps 201 to 202 of this embodiment, the temperature deviation (set value - measured value) and the rate of change of temperature deviation of the first PT100 array measured by the chamber are used as two input quantities. Through a fuzzy control rule base, the P (proportional), I (integral), and D (derivative) parameters of the PID controller are dynamically adjusted in real time: When the deviation is large, such as during chamber preheating or the introduction of new samples: P is increased and I is decreased to quickly increase / decrease power and shorten the temperature control response time. When the deviation is small, such as during steady-state temperature control with a deviation ≤0.2℃: P is decreased, I is increased, and D is fine-tuned to avoid frequent power fluctuations and achieve precise temperature control without overshoot. When the rate of change of deviation is large, such as a sudden drop in temperature when the tube is opened: D is increased to predict the temperature change trend in advance, quickly intervene for compensation, and suppress the fluctuation amplitude.
[0065] Specifically, for example: when the limit switch of the insulation door is triggered and the T door detects a temperature drop of ≥0.1℃, the following measures are taken: 1. Immediately increase the heating / cooling power to 120%~150% of the rated power, with small power overshoot, and quickly replenish heat / cool; 2. Switch the fuzzy PID to "fast compensation mode" and increase the D parameter; 3. Increase the speed of the micro-convection fan inside the cavity to accelerate heat exchange.
[0066] When the main door limit switch is triggered, and the T door detects a temperature drop / rise of ≥0.2℃, the following measures are taken: 1. Power is directly increased to 150%~200% of the rated power; 2. Temperature control is prioritized on the aluminum plate wall to ensure stable temperature of the heat exchanger; 3. The overall swing is shut down to reduce airflow disturbance and reduce heat loss.
[0067] Reference Figure 5 , Figure 5 A schematic flowchart of the constant temperature storage method in an embodiment of the present invention is shown. In some embodiments, adjusting the temperature of the test tube incubator according to the cavity temperature and the wall temperature further includes, but is not limited to, steps 301 to 302:
[0068] Step 301: Compare the cavity temperature with the wall temperature to obtain the compensation temperature.
[0069] Step 302: Adjust the PID parameters of the wall temperature according to the compensation temperature to obtain the target temperature.
[0070] In steps 301 to 302 of the embodiments of this application, when the equipment is turned on / the constant temperature setting is changed, the PID parameter self-tuning is automatically performed: by adjusting the power of the cold and heat source by a small step, the response curve of the cavity temperature is collected, the thermal inertia of the aluminum plate liner and the heat loss coefficient of the chamber are calculated, and the parameter threshold of the fuzzy rule library is automatically optimized to adapt to different laboratory environments and hardware aging after long-term use of the equipment, such as slight wear of the seals and TEC efficiency decay.
[0071] It should be noted that when the temperature difference between the wall surface and the cavity center is greater than 0.1℃, the system switches to a wall-priority variable parameter PID controller to fine-tune the power of the hot and cold sources. This utilizes the heat dissipation characteristics of the aluminum plate to quickly level out the temperature difference and ensure that there are no local hot or cold spots inside the cavity.
[0072] Furthermore, in some embodiments, the two PT100 sensor arrays of the pre-arranged cavity main measurement and inner liner wall compensation are used to perform signal weighted fusion, upgrading "single-point temperature control" to "cavity full-area temperature sensing control", allowing the temperature control algorithm to obtain more comprehensive temperature information and avoid temperature control errors caused by single-point temperature measurement deviation.
[0073] The weighting principle includes core measurement as the primary factor and compensation as a secondary factor. The fused reference temperature Tfusion = K1 × Tprimary + K2 × Twall. K1, the primary measurement weight, is 0.7-0.8, directly reflecting the true temperature of the sample's environment. K2, the wall compensation weight, is 0.2-0.3, reflecting the heat output state of the heat source and predicting temperature changes in advance.
[0074] In addition, this application also discloses a constant temperature storage device for a test tube incubator, please refer to... Figure 6 , Figure 6 This invention discloses a module block diagram of a constant temperature storage device according to one embodiment. In some embodiments, the constant temperature storage device can implement the above-described constant temperature storage device, which includes: a cavity temperature acquisition module 201, a wall temperature acquisition module 202, and a temperature adjustment module 203, all of which are communicatively connected.
[0075] The cavity temperature acquisition module 201 acquires the temperature of the cavity of the test tube incubator in real time, obtaining the cavity temperature. The wall temperature acquisition module 202 acquires the temperature of the wall of the test tube incubator in real time, obtaining the wall temperature. The temperature adjustment module 203 adjusts the temperature of the test tube incubator based on the cavity temperature and the wall temperature.
[0076] The cavity temperature of the test tube incubator is acquired in real time by the cavity temperature acquisition module 201, which is detected by the first PT100 sensor array. The wall temperature is acquired in real time by the wall temperature acquisition module 202, which is detected by the second PT100 sensor array. Based on the cavity temperature and wall temperature and combined with a preset composite temperature control algorithm, the temperature of the test tube incubator is adjusted. By abandoning the coarse control of traditional single-point temperature PID, a medical-grade high-precision composite temperature control algorithm is adopted, and hardware actions are matched for linkage control. Ultimately, the steady-state temperature fluctuation and transient fluctuation are reduced, and the effect of rapid temperature constantness is achieved.
