Description

Technical Field

[0001] The present invention specifically relates to a temperature-controlled storage device for endocrine detection liquid, belonging to the technical field of detection liquid storage. Background Art

[0002] Endocrine detection is an important means for clinical diagnosis and treatment of endocrine diseases, and the accuracy of detection results depends to a great extent on the quality of the detection liquid; the detection liquid is sensitive to temperature, and temperature fluctuations will cause changes in its components, thereby affecting the accuracy of detection results; currently, the commonly used detection liquid storage devices are mostly ordinary refrigerators or freezers, and the storage devices have problems such as low temperature control accuracy, large temperature fluctuations, and uneven temperature control, making it difficult to meet the strict requirements for the storage temperature of endocrine detection liquid; existing temperature-controlled storage devices used alone, such as an endocrine detection liquid temperature-controlled storage device disclosed in Chinese Patent Publication No.: CN111488011A, separates and stores different endocrine detection liquids through an adjustment unit, a partition board, and a mounting plate, performs internal circulation of the air inside the box body through a first exhaust fan, a second exhaust fan, and an air exchange pipe, and makes the temperature inside the box body be controlled at a constant temperature through a temperature sensor, a cooling unit, and a heating unit; however, the storage method of the above storage device has high energy consumption, especially when the door is frequently opened and closed, the energy consumption increases sharply; and after the door is opened and closed, the temperature fluctuates greatly and it takes a long time to return to the set temperature; and when the door is opened and closed, all the sampling tubes are easily exposed to the air. In addition, when there is a sudden power failure in the existing storage device, the device cannot maintain a constant temperature for a long time, resulting in the failure of the stored detection liquid. Summary of the Invention

[0003] To solve the above problems, the present invention proposes a temperature-controlled storage device for endocrine detection liquid. When storing or taking out the sampling tubes containing endocrine detection liquid, there is no need to open or close the door, and the access of the target sampling tube will not interfere with other sampling tubes, which can protect the endocrine detection liquid inside other sampling tubes and make the storage safer.

[0004] The temperature-controlled storage device for endocrine detection liquid of the present invention includes

[0005] A heat-insulating box body, on the front side of the heat-insulating box body, a main control unit for overall control of the machine and a touch screen module are fixed. On the top of the rear side of the heat-insulating box body, a detection window is provided, and inside the detection window, a bar code scanning unit and a light compensator are provided; a window for the entry and exit of sampling tubes is provided on the heat-insulating box body opposite to the detection window; on the inner top surface of the heat-insulating box body, a thermoelectric refrigeration unit is fixed; the thermoelectric refrigeration unit can provide cold for the inside of the heat-insulating box body, and through the downward flow of cold, achieve comprehensive refrigeration of the entire inside of the heat-insulating box body. The touch screen module can view the storage situation of the sampling tubes in real time and can select the target sampling tube to be automatically taken out by touch. The detection window and the window are opposite, which can make the bar code scanning unit face the bar code of the sampling tube, and the light compensator can supplement light for bar code scanning.

[0006] Hole-frame phase change unit. The hole-frame phase change unit includes a phase change box fixed in the middle of the heat-insulating box body through a bracket. A through pipe is embedded in the phase change box body. A phase change storage material is arranged inside the phase change box body. A heat exchange pipe is also fixed inside the phase change box body. The heat exchange end of the heat exchange pipe is connected to the compressor refrigeration unit. The phase change storage material adopts a paraffin-based composite phase change material (such as paraffin-graphene composite phase change material), and the phase change temperature of the phase change storage material matches the storage temperature of the detection liquid (such as 4°C ± 0.5°C or -20°C ± 1°C). The hole-frame phase change unit serves as a placement bracket for the sampling pipe. At the same time, the phase change storage material can suppress temperature fluctuations and reduce the number of compressor starts and stops. And in the event of a sudden power outage, the phase change storage material of the hole-frame phase change unit can maintain the temperature of the sampling pipe not exceeding -15°C for 24 hours under the storage condition of -20°C. By configuring a super capacitor, the holding time of the sampling pipe with a temperature not exceeding -15°C can be further extended.

[0007] Detection liquid inlet and outlet action mechanism. The detection liquid inlet and outlet action mechanism includes a first electric cross slide fixed to the bottom surface of the phase change box body and a second electric cross slide fixed to the upper side edge of the phase change box body. A first air cylinder is fixed to the sliding end of the first electric cross slide, and a rubber disk is fixed to the telescopic end of the first air cylinder. A slide seat is fixed to the sliding end of the second electric cross slide, and a second air cylinder is fixed to the slide seat. A chuck for clamping the sampling pipe is fixed to the telescopic end of the second air cylinder.

[0008] Detection liquid inlet and outlet alignment unit. The detection liquid inlet and outlet alignment unit includes an upper guide hopper fixed to the inner bottom surface of the window. A sliding opening is provided on the upper guide hopper. A third air cylinder is arranged directly below the upper guide hopper, and a lower guide hopper is fixed to the telescopic end of the third air cylinder. The third air cylinder drives the lower guide hopper to align the top of the sampling pipe, and the upper guide hopper can align the top of the sampling pipe, so that the axis line of the sampling pipe is directly opposite to the center line of the window.

[0009] Furthermore, a head is movably embedded in the inner side of the window. The head can assist in pressing the sampling pipe in place. At the same time, the head can seal the window to avoid cold leakage.

[0010] Furthermore, a pressure sensor is arranged inside the lower guide hopper. The pressure sensor can detect whether the sampling pipe is pressed in place. When the sampling pipe needs to be taken out, the pressure sensor detects the upward pressure of the lower guide hopper. When the pressure is too high, an alarm signal is generated, and the sampling pipe is taken out and realigned to avoid movement interference.

[0011] Further, the chuck includes clamping plates. A U-shaped opening is formed at the front end of the clamping plates. An elastic plate is hinged to the inner front end of the U-shaped opening. Long strip-shaped slideways are formed on both sides of the U-shaped opening. A limiting rod is slidably arranged inside the long strip-shaped slideways. A spring body is arranged between the U-shaped opening and the elastic plate of the limiting rod. A first electromagnet magnetically attracting the elastic plate is fixed outside the U-shaped opening. A sliding cylinder is fixed to the top surface of the clamping plates. A second electromagnet is fixed to the inner end of the sliding cylinder. A locking pin is slidably arranged inside the sliding cylinder. A third electromagnet magnetically attracting and cooperating with the second electromagnet is fixed to the inner end of the locking pin. When the chuck clamps the sampling tube, the second electric cross slide moves to drive the clamping plates to move, so that the U-shaped opening of the clamping plates faces the upper pipe wall of the sampling tube, and the U-shaped opening of the clamping plates is clamped with the pipe wall. When clamping, the first electromagnet is in an open circuit state, and the elastic plate is pressed against the pipe wall of the sampling tube and compresses the spring body. As the clamping plates continuously approach the sampling tube, the sampling tube passes through the elastic plate, and the inner end of the elastic plate abuts against the pipe wall of the sampling tube. Then, the second electromagnet and the third electromagnet repel each other, so as to drive the locking pin to slide forward along the sliding cylinder, and the locking pin presses the top of the sampling tube to realize the clamping of the sampling tube. When unlocking is required, the second electromagnet and the third electromagnet attract each other, and the locking pin slides along the sliding cylinder again, so that the locking pin disengages from the sampling tube. Then, the first electromagnet acts, and the elastic plate is attracted by the first electromagnet, so that the elastic plate compresses the spring body. At this time, the U-shaped opening of the clamping plates is completely exposed. The second electric cross slide moves to drive the clamping plates to move, so that the U-shaped opening is separated from the sampling tube.

[0012] Further, a guiding part is fixed to the top of the pipe passing. Through the guiding part, the sampling tube can be smoothly guided into the hole position of the hole rack phase change unit.

[0013] Further, the main control unit is respectively connected to a bar code scanning unit, a bar code hole position association unit, a bar code hole position storage unit, a hole rack temperature transmitter and a chamber temperature transmitter. The hole rack temperature transmitter and the chamber temperature transmitter are respectively fixed to the top surface of the hole rack phase change unit and the bottom surface of the heat insulation box body.

[0014] The hole rack temperature transmitter and the chamber temperature transmitter are used to monitor the internal temperatures of the hole rack phase change unit and the heat insulation box body respectively. When the hole rack temperature transmitter reaches the trigger value, the compression refrigeration unit and the semiconductor refrigeration unit are started synchronously. Through the cold quantity transfer in contact between the phase change storage material and the sampling tube, and the radiant cold quantity provided by the semiconductor refrigeration unit, the temperature of the sampling tube is quickly controlled within a safe range. When the internal temperature of the heat insulation box body reaches the first trigger value, only the semiconductor refrigeration unit is turned on to control the cold quantity inside the heat insulation box body. When the internal temperature of the heat insulation box body reaches the second trigger value, the compression refrigeration unit and the semiconductor refrigeration unit are started synchronously. Among them, the temperature of the first trigger value is lower than the temperature of the second trigger value, so as to quickly adjust the temperature of the sampling tube and make the storage device in a high energy efficiency mode for a long time.

[0015] Further, the working process of the main control unit is as follows: Embed the sampling tube into the heat-insulating box body from the window. During the embedding process, align the barcode outside the sampling tube with the barcode scanning unit. When the barcode scanning unit detects the barcode, display successful barcode scanning through the touch screen module. At this time, the main control unit detects the idle hole positions of the hole rack phase change unit, obtains all blank hole positions, and then selects the target hole position according to the stroke of the second electric cross slide; The main control unit binds the barcode of the sampling tube and the hole position through the barcode-hole position association unit and sends it to the barcode-hole position storage unit for storage; Then, the main control unit determines whether the pressure sensor detects pressure. After detecting the pressure, it determines that the sampling tube is pressed down in place. Then, the chuck clamps the sampling tube, and the third cylinder drives the lower guiding hopper to move downward and separate from the sampling tube. Then, the second electric cross slide moves, sending the sampling tube directly above the hole position. The second cylinder moves, embedding the sampling tube into the hole rack phase change unit; After the sampling tube arrives at the position, the chuck unlocks and separates from the sampling tube; The storage of the sampling tube is completed; When it is necessary to take out the sampling tube, operate the touch screen module, select the corresponding barcode through the touch screen module. After the main control unit obtains the barcode, the main control unit gives a signal to the first electric cross slide and associates the hole position according to the barcode stored in the barcode-hole position storage unit. Then, the first electric cross slide drives the first cylinder to move, making the glue tray move directly below the positioned hole position. Then, the first cylinder moves, jacking up the sampling tube. The second electric cross slide drives the chuck to move, and the chuck clamps the sampling tube and lifts the sampling tube away from the hole position through the second cylinder and moves directly below the window; At this time, the third cylinder moves. The third cylinder drives the upper guiding hopper to align with the bottom guide of the sampling tube and drives the sampling tube to move upward. During the upward movement, output guiding is carried out through the upper guiding hopper, enabling the sampling tube to be accurately exported from the window; The taking out of the sampling tube is completed; The main control unit unbinds the hole position corresponding to the barcode of the sampling tube through the barcode-hole position association unit.

[0016] Further, the selection of the target hole position is specifically as follows: When the X-direction independent stroke or the Y-direction independent stroke of the second electric cross slide is less than the set value, select the X-direction independent stroke or the Y-direction independent stroke. When both the X-direction independent stroke and the Y-direction independent stroke are less than the set value, select the independent stroke with a shorter stroke; When both the X-direction independent stroke and the Y-direction independent stroke are not less than the set value, select the hole position with the shortest total stroke of the X-direction stroke and the Y-direction stroke of the second electric cross slide; By calculating the stroke of the chuck moving to the target hole position, the hole position with the best stroke can be preferentially selected.

[0017] Compared with the prior art, for the temperature-controlled storage device of the endocrine detection liquid of the present invention, when storing or taking out the sampling tube containing the endocrine detection liquid, there is no need to open or close the door. It can automatically send the sampling tube into the storage position or automatically take it out from the storage position, realizing automatic access. The access of the target sampling tube will not interfere with other sampling tubes, which can protect the endocrine detection liquid inside other sampling tubes and make the storage safer; when the sampling tube is stored, the hole rack phase change unit can not only be used as a placement bracket for the sampling tube, facilitating the positioning and storage of the sampling tube. At the same time, through the contact heat conduction method and the phase change storage material, it can suppress the temperature fluctuation, reduce the start-stop frequency of the compressor, and can provide a stable temperature-controlled storage environment for the sampling tube. And in case of sudden power failure, it can maintain the temperature of the sampling tube not exceeding -15°C for 24 hours. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The chuck includes a clamping plate 19. A U-shaped opening 20 is formed at the front end of the clamping plate 19. An elastic plate 21 is hinged to the inner front end of the U-shaped opening 20. Long strip-shaped sliding grooves 22 are formed on both sides of the U-shaped opening 20. A limiting rod 23 is slidably arranged inside the long strip-shaped sliding grooves 22. A spring body is arranged between the limiting rod 23 and the U-shaped opening 20 and the elastic plate 21. A first electromagnet 24 that magnetically attracts the elastic plate 21 is fixed outside the U-shaped opening 20. A sliding cylinder 25 is fixed on the top surface of the clamping plate 19. A second electromagnet is fixed at the inner end of the sliding cylinder 25. A locking pin 26 is slidably arranged inside the sliding cylinder 25. A third electromagnet 27 that magnetically attracts and cooperates with the second electromagnet is fixed at the inner end of the locking pin 26. When the chuck clamps the sampling tube 4, the second electric cross slide 9 operates to drive the clamping plate 19 to move, so that the U-shaped opening 20 of the clamping plate 19 faces the upper pipe wall of the sampling tube 4, and the U-shaped opening 20 of the clamping plate 19 is clamped with the pipe wall. When clamping, the first electromagnet 24 is in an open circuit state, and the elastic plate 21 is pressed against the pipe wall of the sampling tube 4 and compresses the spring body. As the clamping plate 19 continuously approaches the sampling tube 4, the sampling tube 4 passes through the elastic plate 21, and the inner end of the elastic plate 21 abuts against the pipe wall of the sampling tube 4.

When the rack temperature transmitter reaches the trigger value, the compression refrigeration unit and the semiconductor refrigeration unit are started synchronously. Through the contact heat transfer of the phase change storage material with the sampling tube 4, and with the radiant cooling provided by the semiconductor refrigeration unit, the temperature of the sampling tube 4 is quickly controlled within the safe range.

After detecting the pressure, it determines that the sampling tube 4 is pressed in place. Then, the chuck clamps the sampling tube 4, and the third cylinder 16 drives the lower guide hopper 17 to move downward and separate from the sampling tube 4. Then, the second electric cross slide 9 operates to send the sampling tube 4 to directly above the hole position, and the second cylinder 13 operates to insert the sampling tube 4 into the hole rack phase change unit; After the sampling tube 4 is in place, the chuck unlocks and separates from the sampling tube 4; The storage of the sampling tube 4 is completed; When it is necessary to take out the sampling tube 4, operate the touch screen module 2, select the corresponding barcode through the touch screen module 2. After the main control unit obtains the barcode, the main control unit gives a signal to the first electric cross slide 8 and associates the hole position according to the barcode-hole position stored in the barcode-hole position storage unit. Then, the first electric cross slide 8 drives the first cylinder 10 to operate, so that the glue tray 11 moves to directly below the positioned hole position. Then, the first cylinder 10 operates to lift the sampling tube 4. The second electric cross slide 9 drives the chuck to operate, and the chuck clamps the sampling tube 4 and lifts the sampling tube 4 out of the hole position through the second cylinder 13 and advances to directly below the window 5; At this time, the third cylinder 16 operates, and the third cylinder 16 drives the upper guide hopper 14 to align with the bottom of the sampling tube 4 and drives the sampling tube 4 to move upward.

The main control unit binds the barcode and the hole position of the sampling tube through the barcode hole position association unit, and sends them to the barcode hole position storage unit for storage. Then, the main control unit determines whether the pressure sensor detects pressure. After detecting the pressure, it determines that the sampling tube is pressed into place. Then, the chuck clamps the sampling tube, and the third cylinder drives the lower guide bucket to move downward to separate from the sampling tube. Then, the second electric cross slide moves to send the sampling tube to the top of the hole position, and the second cylinder moves to embed the sampling tube into the hole rack phase change unit. After the sampling tube is in place, the clamp The head is unlocked and separated from the sampling tube; the sampling tube storage is completed; when the sampling tube needs to be taken out, the touch screen module is controlled, and the corresponding barcode is selected through the touch screen module. After the main control unit obtains the barcode, the main control unit gives a signal to the first electric cross slide, and associates the hole position according to the barcode stored in the barcode hole position storage unit. Then, the first electric cross slide drives the first cylinder to move, so that the rubber disc moves to the bottom of the positioned hole position. Then, the first cylinder moves to push the sampling tube up, and the second electric cross slide drives the chuck to move. The chuck clamps the sampling tube, and the sampling tube is lifted up and separated from the hole position through the second cylinder, and moves to the bottom of the window; at this time, the third cylinder moves, and the third cylinder drives the upper guide bucket to align with the bottom guide of the sampling tube, and drives the sampling tube to move upward. When moving upward, the upper guide bucket is used for output guidance, so that the sampling tube is accurately guided out of the window; the sampling tube is taken out; the main control unit unbinds the hole position corresponding to the barcode of the sampling tube through the barcode hole position association unit.

8. The temperature-controlled storage device for endocrine detection liquid according to claim 7, characterized in that: The target hole position selection is specifically as follows: when the X-direction independent stroke or the Y-direction independent stroke of the second electric cross slide is less than a set value, the X-direction independent stroke or the Y-direction independent stroke is selected; when the X-direction independent stroke or the Y-direction independent stroke are both less than the set value, the independent stroke with a shorter stroke is selected; when both the X-direction independent stroke and the Y-direction independent stroke are not less than the set value, the hole position with the shortest total stroke of the X-direction stroke and the Y-direction stroke of the second electric cross slide is selected.
