Description

Technical Field

[0001] This utility model relates to the field of temperature detection technology, specifically a temperature calibration device for a plasma quick-freezing machine. Background Technology

[0002] Clinical blood transfusion is an important method of medical treatment. In order to ensure the quality of plasma, it is required to rapidly freeze fresh frozen plasma and cryoprecipitate clotting factors. The core temperature must be reduced to below 30°C within 60 minutes. There are various types of equipment for preparing fresh frozen plasma, but the main equipment is a specialized plasma quick-freezing machine.

[0003] A plasma quick-freezing machine temperature calibration device, disclosed in CN220772388U, includes: a temperature monitoring instrument and multiple plasma simulation bags, wherein the multiple plasma simulation bags are disposed on one side of the temperature monitoring instrument. It also includes: multiple wires, equidistantly fixedly connected to one side of the temperature monitoring instrument. A temperature sensor is fixedly connected to one end of each of the multiple wires. Through the threaded engagement of a sleeve rod and a hollow round rod, the temperature sensor can be moved into the interior of the plasma simulation bag and kept in a relatively fixed state. Thus, the temperature of the physiological saline in the storage chamber can be detected by the temperature monitoring instrument. Based on the detected multiple temperature sets, the temperature deviation, uniformity, fluctuation, and cooling rate of the plasma quick-freezing machine can be calculated. Therefore, the temperature of the plasma quick-freezing machine can be calibrated based on the actual detected temperature, thereby improving the plasma storage effect.

[0004] However, the following problems still exist in actual use: The calibration of the plasma quick-freezing machine should use a temperature monitoring instrument or temperature calibrator that is traceable by national metrological standards, in conjunction with a standard temperature sensor for measurement. Placing a plasma simulation bag (containing physiological saline or other simulated media) inside the quick-freezing machine and placing the temperature sensor inside the bag can accurately reflect the heat transfer state during the freezing process. At the same time, it is also necessary to measure the temperature at different locations inside the quick-freezing machine simultaneously using multiple sensors to calculate key performance indicators such as temperature deviation, uniformity, fluctuation, and cooling rate, so as to improve the accuracy of temperature detection and calibration.

[0005] Therefore, a temperature calibration device for a plasma quick-freezing machine is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a temperature calibration device for a plasma quick-freezing machine, in order to solve the problem that it is inconvenient to quickly adjust the position of the plasma simulation bag, which makes it difficult to measure the temperature at different positions inside the quick-freezing machine, reduces the effectiveness and integrity of temperature detection, and affects subsequent temperature calibration.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a plasma quick-freezing machine temperature calibration device, comprising a quick-freezing machine body, a plasma simulation bag body, and casters fixedly installed around the bottom of the quick-freezing machine body. The quick-freezing machine body has two horizontally parallel placement cavities inside, and a cover plate is slidably installed inside the placement cavity.

[0008] Also includes:

[0009] The placement cavity is equipped with a detection component, which includes a tray and a fixing plate fixedly connected to the top of the tray. Multiple side plates are fixedly connected longitudinally and parallel to one side of the fixing plate, and a connecting tube is fixedly installed on one side of the plasma simulation bag body.

[0010] The fixing plate has a fixing tube fixedly installed inside, a temperature sensor fixedly installed at one end of the fixing tube, and a guide plate fixedly connected to the outside of the temperature sensor. The guide plate is slidably installed with the side plate.

[0011] Preferably, the side plate and the fixing plate are perpendicular to each other, there are no fewer than four side plates, the connecting pipe is internally threaded with an end cap, the fixing pipe is internally provided with a wire, and a sliding groove is longitudinally opened on one side of the side plate, and a screw is rotatably connected inside the sliding groove.

[0012] Preferably, one end of the screw passes through the fixing plate and is fixedly connected to an end block, the guide plate is slidably connected to the slide groove, the guide plate is threadedly connected to the screw, the guide plate is in contact with the inner wall of the slide groove, a fixing ring is fixedly connected to the outside of the temperature sensor, a spring is sleeved on the outside of the temperature sensor, and one end of the spring is fixedly connected to the fixing ring.

[0013] Preferably, two pins are symmetrically fixedly connected to the side of the fixing ring away from the fixing tube, and two connecting pieces are symmetrically fixedly connected to the outside of the connecting tube. The connecting pieces have slots inside, and the pins are inserted into the slots of the connecting pieces for fixation. Bolts are threadedly connected to the outside of the connecting pieces, and screw holes are also provided inside the pins. The bolts are threadedly connected to the screw holes of the pins.

[0014] Preferably, the detection assembly further includes a sealing plate fixedly connected to one side of the front of the tray, a temperature monitoring instrument fixedly installed on the outside of the sealing plate, the other end of each fixing tube being connected to the temperature monitoring instrument, and a display screen fixedly installed on the top of the temperature monitoring instrument.

[0015] Preferably, the cover plate has a clearance groove on the side near the sealing plate, the sealing plate is engaged with the clearance groove, the cover plate is uniformly fixedly connected with a positioning rod on the side near the sealing plate, the sealing plate has a positioning groove uniformly opened on the side near the positioning rod, and the positioning rod is engaged with the positioning groove.

[0016] Preferably, there are no fewer than three positioning rods and positioning grooves, and a sealing strip is provided on the outer side of the sealing plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: A detection component is provided. By rotating the end block, the positions of the guide plate and temperature sensor are adjusted. Then, the temperature sensor is inserted into the connecting pipe, the pin is inserted into the connecting piece, and finally the bolt is tightened to facilitate the connection between the temperature sensor and the connecting pipe. At this time, the temperature sensor detects the temperature inside the plasma simulation bag body. It can autonomously adjust and select the temperature of the plasma simulation bag body at different locations to maintain uniform sampling. The temperature monitoring instrument sequentially detects the temperature of different sampling points and displays the specific values ​​on the display screen. This allows operators to calculate the temperature deviation, uniformity, fluctuation, and cooling rate of the quick-freezing machine body based on the multiple sets of detected temperatures. Therefore, the temperature of the quick-freezing machine body can be calibrated based on the actual detected temperature. The specific details are as follows:

[0018] 1. By setting up the detection components, the operator first injects physiological saline into the plasma simulation bag. For plasma simulation bags where temperature is not being detected, the connecting tube is sealed to the end cap via a threaded connection. For plasma simulation bags where temperature detection is required, the end block is rotated, causing the screw to rotate. The screw rotation causes the guide plate to slide inside the groove, thereby adjusting the position of the guide plate and the temperature sensor. Then, the temperature sensor is inserted into the connecting tube, compressing the spring and causing the temperature sensor to move the fixing ring and the pin. The pin is inserted into the connecting piece, and finally, the bolt is tightened to fix the pin, facilitating the connection between the temperature sensor and the connecting tube. At this point, the end of the temperature sensor is located at the internal center of the plasma simulation bag, facilitating the detection of the plasma simulation bag. The internal temperature control allows operators to independently adjust and select the temperature of the plasma simulation bag at different locations, ensuring uniform sampling. A wire is installed inside the fixing tube, and the tray is placed in the placement chamber. The temperature monitoring instrument sequentially detects the temperature at different sampling points and displays the specific values ​​on the screen. This allows operators to calculate the temperature deviation, uniformity, fluctuation, and cooling rate of the blast freezer based on the multiple temperature readings. This enables temperature calibration of the blast freezer based on the actual measured temperature, thereby improving the plasma storage effect. This solves the problem of difficulty in quickly adjusting the position of the plasma simulation bag, which hinders temperature measurement at different locations within the blast freezer, reducing the effectiveness and overall consistency of temperature detection and affecting subsequent temperature calibration.

[0019] 2. By setting up a placement cavity, cover plate, sealing plate, positioning rod, and positioning groove, the cover plate is raised and lowered by an electric slide rail to facilitate the closure of the placement cavity. The interior of the placement cavity is used to place the tray and the plasma simulation bag body. When the cover plate moves to close, the cover plate drives the positioning rod to move, and the positioning rod is inserted into the positioning groove respectively, thereby limiting the sealing plate and the tray. A sealing strip is set on the outer ring of the sealing plate to maintain the airtight state of the placement cavity, thereby facilitating the quick-freezing treatment of the plasma simulation bag body.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 7 The present invention provides a technical solution: a plasma quick-freezing machine temperature calibration device, including a quick-freezing machine body 1, a plasma simulation bag body 6 and casters 2 fixedly installed around the bottom of the quick-freezing machine body 1. The quick-freezing machine body 1 has two horizontal parallel placement cavities 3 inside, and a cover plate 4 is slidably installed inside the placement cavities 3. The quick-freezing machine body 1 adopts a double-layer flat-plate plasma quick-freezing machine.

[0030] The placement cavity 3 is equipped with a detection component 5, which includes a tray 51 and a fixing plate 52 fixedly connected to the top of the tray 51. Multiple side plates 53 are fixedly connected longitudinally and parallel to one side of the fixing plate 52. A connecting tube 54 is fixedly installed on one side of the plasma simulation bag body 6.

[0031] The operator first injects physiological saline into the plasma simulation bag body 6. For plasma simulation bags 6 whose temperature is not detected, the connecting tube 54 is threadedly connected to the end cap 7 to seal the bag. For plasma simulation bags 6 whose temperature needs to be detected, the operator rotates the end block 510. The end block 510 drives the screw 59 to rotate. The rotation of the screw 59 causes the guide plate 57 to slide inside the slide groove 58, thereby adjusting the position of the guide plate 57 and the temperature sensor 56.

[0032] A fixing tube 55 is fixedly installed inside the fixing plate 52. A temperature sensor 56 is fixedly installed at one end of the fixing tube 55. The temperature sensor 56 is a platinum-electric-BDRTD. A guide plate 57 is fixedly connected to the outside of the temperature sensor 56. The guide plate 57 is slidably installed with the side plate 53.

[0033] The side plate 53 is perpendicular to the fixed plate 52. There are no fewer than four side plates 53. The connecting pipe 54 is internally threaded with an end cap 7. The fixed pipe 55 is internally equipped with a wire. A sliding groove 58 is longitudinally opened on one side of the side plate 53. A screw 59 is rotatably connected inside the sliding groove 58.

[0034] One end of the screw 59 passes through the fixing plate 52 and is fixedly connected to the end block 510. The guide plate 57 is slidably connected to the slide groove 58. The guide plate 57 is threadedly connected to the screw 59. The guide plate 57 is in contact with the inner wall of the slide groove 58. A fixing ring 511 is also fixedly connected to the outside of the temperature sensor 56. A spring 512 is sleeved on the outside of the temperature sensor 56. One end of the spring 512 is fixedly connected to the fixing ring 511.

[0035] Two pins 513 are symmetrically fixedly connected to the side of the fixing ring 511 away from the fixing tube 55. Two connecting pieces 514 are symmetrically fixedly connected to the outside of the connecting tube 54. The connecting pieces 514 have slots inside. The pins 513 are inserted into the slots of the connecting pieces 514 for fixation. The connecting pieces 514 are threadedly connected to the outside of the bolts 515. The pins 513 also have screw holes inside. The bolts 515 are threadedly connected to the screw holes of the pins 513.

[0036] Next, the temperature sensor 56 is inserted into the connecting tube 54, the spring 512 is compressed, and the temperature sensor 56 drives the fixing ring 511 and the pin 513 to move. The pin 513 is inserted into the connecting piece 514. Finally, the bolt 515 is tightened to fix the pin 513, which facilitates the docking of the temperature sensor 56 and the connecting tube 54. At this time, the end of the temperature sensor 56 is located at the internal center of the plasma simulation bag body 6, which facilitates the detection of the internal temperature of the plasma simulation bag body 6. This allows the operator to independently adjust and select the temperature of the plasma simulation bag body 6 at different locations to maintain uniform sampling.

[0037] The detection assembly 5 also includes a sealing plate 516 fixedly connected to one side of the front of the tray 51. A temperature monitoring instrument 8 is fixedly installed on the outside of the sealing plate 516. The other end of the fixing tube 55 is connected to the temperature monitoring instrument 8. A display screen 9 is fixedly installed on the top of the temperature monitoring instrument 8.

[0038] A wire is installed inside the fixed tube 55, and then the tray 51 is placed in the placement cavity 3. The temperature monitoring instrument 8 detects the temperature of different sampling points in sequence and displays the specific values ​​on the display screen 9. This allows the operator to calculate the temperature deviation, uniformity, fluctuation and cooling rate of the quick-freezing machine body 1 based on the multiple sets of detected temperatures. This allows the temperature of the quick-freezing machine body 1 to be calibrated according to the actual detected temperature, thereby improving the effect of plasma storage.

[0039] A clearance groove is provided on the side of the cover plate 4 near the sealing plate 516. The sealing plate 516 is engaged with the clearance groove. Positioning rods 517 are uniformly fixedly connected on the side of the cover plate 4 near the sealing plate 516. Positioning grooves 518 are uniformly provided on the side of the sealing plate 516 near the positioning rods 517. Positioning rods 517 are engaged with the positioning grooves 518.

[0040] The cover plate 4 is raised and lowered by an electric slide rail to facilitate the sealing of the placement cavity 3. The interior of the placement cavity 3 is used to place the tray 51 and the plasma simulation bag body 6. When the cover plate 4 moves to close, the cover plate 4 drives the positioning rod 517 to move. The positioning rod 517 is inserted into the positioning groove 518 respectively, thereby limiting the sealing plate 516 and the tray 51. The outer ring of the sealing plate 516 is provided with a sealing strip to keep the placement cavity 3 in a sealed state, thereby facilitating the quick-freezing treatment of the plasma simulation bag body 6.

[0041] There are at least three positioning rods 517 and positioning grooves 518, and a sealing strip is provided on the outer side of the sealing plate 516.

[0042] Working principle:

[0043] Before using this plasma quick-freezing machine temperature calibration device, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 7 As shown, the operator first injects physiological saline into the plasma simulation bag body 6. For plasma simulation bags 6 without temperature detection, the connecting tube 54 is threadedly connected to the end cap 7 to seal the bag. For plasma simulation bags 6 where temperature detection is required, the positions of the guide plate 57 and the temperature sensor 56 are adjusted to align the temperature sensor 56 with the connecting tube 54. This allows the operator to independently adjust and select the temperature of the plasma simulation bag body 6 at different locations, ensuring uniform sampling. Next, the tray 51 is placed in the placement cavity 3. When the cover plate 4 moves to close, the cover plate 4 drives the positioning rod 5. 17. The positioning rods 517 are inserted into the positioning slots 518 respectively. The outer ring of the sealing plate 516 is provided with a sealing strip to keep the placement cavity 3 sealed, so as to facilitate the quick-freezing treatment of the plasma simulation bag body 6. The temperature monitoring instrument 8 detects the temperature of different sampling points in sequence and displays the specific values ​​on the display screen 9. This allows the operator to calculate the temperature deviation, uniformity, fluctuation and cooling rate of the quick-freezing machine body 1 based on the multiple sets of detected temperatures. This allows the temperature of the quick-freezing machine body 1 to be calibrated according to the actual detected temperature, thereby improving the plasma storage effect.
