[0021] Preferably, a silica gel sleeve is arranged outside the driving wheel of the encapsulation mechanism.

[0022] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0023] 1. An encapsulation mechanism is arranged on one side of the box body of the present invention, which is convenient for medical staff to seal nucleic acid specimen tubes. During the operation process, medical staff do not need to manually open the bag and manually seal it, and it can effectively avoid problems such as the nucleic acid specimen tube tipping, leaking, and accidentally falling to the ground during the sealing process, reducing the workload of medical staff, improving the work efficiency of medical staff, and bringing great convenience to medical staff.

[0024] 2. A storage box is arranged in the box body of the present invention, and the storage box is used to store the encapsulated nucleic acid specimen tubes. Among them, the storage box is made of white transparent plastic material, which is convenient for medical staff to count the number of specimens, can save the specimen handover time of medical staff, and improve work efficiency; a test tube rack is movably arranged in the storage box, and the test tube rack is provided with specimen fixing holes to fix the nucleic acid specimen tubes and prevent the nucleic acid specimen tubes from tipping; a card slot is arranged on one side of the specimen fixing hole, which is convenient for placing identification cards and is beneficial for checking. In the existing specimen transfer box, there is no test tube rack inside. When there are many nucleic acid specimens, they are placed randomly and are easy to fall, which may lead to phenomena such as splashing and leakage of nucleic acid specimens, and then all the nucleic acid specimens in the box need to be recollected; in this way, it not only increases the pain of patients during sampling, increases the workload of medical staff, but also affects the timeliness of nucleic acid test results of patients.

[0025] 3. The present invention is provided with a cold air supply cavity connected to the specimen storage cavity at the lower part of the box body. A drawer is movably arranged in the cold air supply cavity, and ice bags are placed in the drawer. In this way, the ice bags and nucleic acid specimens are placed separately, which can avoid the ice bags and nucleic acid specimens being directly in the same space, so as to prevent the ice bags from being contaminated and can be reused. The box body is provided with a temperature monitoring device, which is used to monitor the temperature in the specimen storage cavity and display the measured real-time temperature on the temperature display panel for medical staff to view. When the measured real-time temperature is higher than the set limit value, it can also give an alarm prompt to ensure that the temperature in the specimen storage cavity meets the requirements. During the transportation of specimens, a transportation cold chain box needs to be used or ice bags need to be added for refrigeration. At present, the transportation cold chain boxes in major hospitals have the defects of heavy weight and small internal specimen storage space, resulting in affected specimen storage. When ice bags are directly placed in the specimen transportation box and directly contact the specimen box or specimen tube, there is also a possibility that the ice bags may be contaminated by the specimens.

[0026] 4. The present invention is respectively provided with a first storage groove and a second storage groove on the left and right sides of the box body. The first storage groove is used to store the specimen barcode summary list, which can avoid the loss of the summary list. The second storage groove is used to store disposable items, such as infectious waste bags, gloves, spare sealing rolls, etc., and has a good classification storage function, which is convenient for medical staff to collect and check specimens. The existing specimen transportation boxes do not have a place to place the barcode summary list, which is easy to cause the loss of the summary list (each patient has its own corresponding barcode information, and every 10 barcodes are pasted on a table made of an A4 paper). The loss of the barcode summary list leads to the loss of the sampling patient information. If the patient information needs to be retrieved, it will greatly increase the workload of the sampling work and the inspection staff, affecting the result reporting time.

[0037] As Figures 1-5As shown in the figure, a nucleic acid specimen transfer box includes a box body 1 and a box cover 2 that is movably covered on the top of the box body 1. A packaging mechanism is provided on one side of the box body 1. The packaging mechanism includes a cover body 15, two shearing members 20, two bag-opening members 23, two heat-sealing members 27, two conveying members 30, a sealing roll 35, and a control device. Among them, the packaging mechanism is located on the left or right side of the box body 1; in this embodiment, the packaging mechanism is located on the right side of the box body 1.

[0038] The cover body 15 is arranged on one side of the box body 1, and its side facing the box body 1 is an open structure. One side of the cover body 15 is hinged to the box body 1, and its opposite side is clamped to the box body 1 through a buckle 16, so that the cover body 15 can be opened and closed, facilitating the replacement of the sealing roll 35 inside it. A through hole 17 for placing a nucleic acid specimen tube is opened at the top of the cover body 15, and a packaging channel 18 for packaging the nucleic acid specimen tube is formed directly below the through hole 17. In this embodiment, a sealing cover 19 is arranged on the top surface of the housing, and the sealing cover 19 is detachably covered on the top of the through hole 17. During use, the sealing cover 19 can be opened. The two shearing members 20, the two bag-opening members 23, the two heat-sealing members 27, and the two conveying members 30 are arranged from top to bottom and are symmetrically arranged on the opposite sides of the packaging channel 18 respectively. That is to say, the two shearing members 20 are symmetrically arranged, the two bag-opening members 23 are symmetrically arranged, the two heat-sealing members 27 are symmetrically arranged, and the two conveying members 30 are symmetrically arranged.

[0039] The shearing member 20 includes a first electric push rod 21 that is horizontally arranged and fixedly connected to the inner wall of the cover body 15, and a blade 22 that is arranged at the telescopic end of the first electric push rod 21 and is close to the through hole 17. Among them, the vertical distance between the blade 22 and the through hole 17 is less than 0.5 cm, preferably 0.2 cm.

[0040] The bag-opening member 23 includes a second electric push rod 24 that is horizontally arranged and fixedly connected to the inner wall of the cover body 15, a suction cup 25 that is arranged at the telescopic end of the second electric push rod 24 and is close to the blade 22, and a negative pressure device 26 arranged in the box body 1. The negative pressure device 26 is connected to the two suction cups 25 through an air pipe. Among them, the vertical distance between the suction cup 25 and the blade 22 is less than 1.0 cm, preferably 0.5 cm.

[0041] The heat-sealing member 27 includes a third electric push rod 28 that is horizontally arranged and fixedly connected to the inner wall of the cover body 15, and a heat-sealing head 29 that is arranged at the telescopic end of the third electric push rod 28 and is close to the suction cup 25. Among them, the vertical distance between the heat-sealing head 29 and the suction cup 25 is less than 0.5 cm, preferably 0.2 cm.

[0042] The transfer member 30 includes a fourth electric push rod 31 horizontally arranged and fixedly connected to the inner wall of the cover body 15, a bracket 32 provided at the telescopic end of the fourth electric push rod 31 and close to the heat sealer 29, a mini motor 33 provided on the bracket 32, and a driving wheel 34 rotatably mounted on the bracket 32 and connected to the mini motor 33. A silica gel sleeve is arranged on the outer side of the driving wheel 34 to increase the friction force and has a buffering effect, which can protect the nucleic acid specimen tube.

[0043] The sealing roll 35 includes a drum and a plurality of sealing bags 36 wound around the drum. A pressure sealing partition strip 37 is arranged between adjacent two sealing bags 36. The length of the sealing bag 36 is greater than the length of the nucleic acid specimen tube. Preferably, the volume of the sealing bag 36 can only accommodate one nucleic acid specimen tube to avoid the inconvenience of specimen checking and placing on the test tube rack due to the too large volume of the sealing bag 36. The sealing bag 36 is preferably a white transparent bag to facilitate observing the information on the nucleic acid specimen tube. A limiting shaft 38 is horizontally arranged at the lower part inside the cover body 15, and the drum is rotatably mounted on the limiting shaft 38. When replacing the sealing roll 35, after installing the sealing roll 35 on the limiting shaft 38, the end of the sealing bag 36 is passed through the encapsulation channel 18 and finally passes out through the through hole 17.

[0044] The control device includes a controller 39, a power supply 40, a push rod driver 41, a motor driver 42, and a control panel 43. The controller 39, the power supply 40, the push rod driver 41, and the motor driver 42 are all arranged in the box body 1, and the control panel 43 is arranged on the outer side of the cover body 15. The negative pressure device 26, the power supply 40, the push rod driver 41, the motor driver 42, and the control panel 43 are all electrically connected to the controller 39. The first electric push rod 21, the second electric push rod 24, the third electric push rod 28, and the fourth electric push rod 31 are all electrically connected to the push rod driver 41. The mini motor 33 is electrically connected to the motor driver 42, and the heat sealer 29 is connected to the power supply 40. Among them, the controller 39 controls the first electric push rod 21, the second electric push rod 24, the third electric push rod 28, and the fourth electric push rod 31 to extend or contract respectively through the push rod driver 41, and the controller 39 controls the mini motor 33 to rotate through the motor driver 42. The control panel 43 is provided with an opening key, a heat sealing and transferring key, and a shearing key.

[0045] Among them, after replacing the sealing roll 35, when using it for the first time, the opening key needs to be triggered. When the opening key is triggered, the controller 39 first controls the two second electric push rods 24 to extend, driving the two suction cups 25 to contact the lower part of the bag mouth of the sealing bag 36; then, the controller 39 controls the negative pressure device 26 to work, and the two suction cups 25 respectively adsorb both sides of the sealing bag 36; finally, the controller 39 controls the two second electric push rods 24 to contract, and the two suction cups 25 move away from each other to open the bag mouth of the sealing bag 36.

[0046] After the medical staff place the nucleic acid specimen tube into the sealed bag 36 through the through hole 17 on the top surface of the housing, they touch the heat-sealing transmission key. At this time, the controller 39 first controls the two fourth electric push rods 31 to extend, so that the two driving wheels 34 are in contact with the sealed bag 36 and gently press and fix the nucleic acid specimen tube. Then, the controller 39 controls the negative pressure device 26 to stop working, and the second electric push rod 24 resets. Then, the controller 39 controls the two third electric push rods 28 to extend, driving the two heat sealers 29 to approach each other, and heat-sealing the lower part of the bag mouth of the sealed bag 36. Then, the controller 39 controls the two third electric push rods 28 to contract and reset, and the two heat sealers 29 move away from each other. Finally, the controller 39 controls the mini motor 33 to rotate, driving the driving wheel 34 to rotate, and upwardly conveying the sealed nucleic acid specimen tube.

[0047] When the packaged nucleic acid specimen tube extends out through the through hole 17, the medical staff take it out upward. When seeing the pressure-sealing partition strip 37 at the bottom of the sealed bag 36, they trigger the shearing key. At this time, the controller 39 first controls the two second electric push rods 24 to extend, driving the two suction cups 25 to tightly press both sides of the sealed bag 36. Then, the controller 39 controls the two first electric push rods 21 to perform extension and contraction actions, driving the two blades 22 to complete the shearing operation. Finally, the controller 39 controls the negative pressure device 26 to work and controls the two second electric push rods 24 to reset, opening the opening of the sealed bag 36. In this way, subsequent operations do not require triggering the bag-opening key until a new sealed roll 35 is replaced, reducing the workload of the medical staff.

[0048] On one side of the box body 1 of the present invention, a packaging mechanism is provided, which is convenient for medical staff to seal the nucleic acid specimen tube. During the operation process, the medical staff do not need to manually open the bag and manually seal it, and can effectively avoid problems such as the nucleic acid specimen tube tipping over, leaking, and accidentally falling to the ground during the sealing process, reducing the workload of the medical staff, improving the work efficiency of the medical staff, and bringing great convenience to the medical staff.

[0049] In addition, a specimen storage cavity for storing nucleic acid specimen tubes is provided in the upper part of the box body 1. A specimen storage box is movably placed in the specimen storage cavity. The specimen storage box includes a box body 3 and a box cover that is movably covered on the box body 3. A sealing strip is provided between the box body 3 and the box cover to ensure the sealing performance of the specimen storage box. The materials of the box body 3 and the box cover are both white transparent plastics. A partition 4 is provided in the middle of the box body 3, dividing the inner cavity of the box body 3 into two storage cavities. A test tube rack 5 is movably placed in the storage cavity. The top surface of the test tube rack 5 has a plurality of specimen fixing holes 6 for inserting the packaged nucleic acid specimen tubes. A card slot 7 for placing an identification card is provided on one side of the specimen fixing hole 6. In this embodiment, two test tube racks 5 are movably provided in each storage cavity, and the two test tube racks 5 are arranged from bottom to top, increasing the specimen storage quantity.

[0050] The present invention provides a storage box inside the box body 1, which is used to store the encapsulated nucleic acid specimen tubes. The storage box is made of white transparent plastic material, which is convenient for medical staff to count the number of specimens, can save the specimen handover time of medical staff, and improve work efficiency. A test tube rack 5 is movably arranged inside the storage box. The test tube rack 5 is provided with specimen fixing holes 6 to fix the nucleic acid specimen tubes and prevent the nucleic acid specimen tubes from tipping over. A card slot 7 is arranged on one side of the specimen fixing hole 6, which is convenient for placing identification cards and is beneficial for checking. In the existing specimen transfer boxes, there is no test tube rack 5 inside. When the number of nucleic acid specimens is large, they are placed randomly and are easy to fall down, which may cause phenomena such as splashing and leakage of nucleic acid specimens, and then all the nucleic acid specimens in the box need to be recollected. In this way, it not only increases the pain of patients during sampling, increases the workload of medical staff, but also affects the timeliness of nucleic acid test results for patients.

[0051] A cold air supply cavity is arranged at the lower part of the box body 1. The cold air supply cavity is communicated with the specimen storage cavity. A drawer 8 is movably arranged inside the cold air supply cavity. Ice bags are placed inside the drawer 8. A fixing buckle 9 for locking the drawer 8 is arranged on the outer side of the box body 1 to prevent the drawer 8 from accidentally coming out. When it is necessary to pull out the drawer 8, just open the fixing buckle 9. The fixing buckle 9 can be a plug buckle or a tower buckle. In this embodiment, the drawer 8 is located at the front side of the box body 1. The box body 1 is provided with a temperature monitoring device 10, which includes a temperature display panel arranged on the front side of the box body 1 and a temperature induction probe arranged inside the specimen storage cavity. The temperature display panel is electrically connected to the temperature induction probe. In this way, the ice bags and the nucleic acid specimens are placed separately, which can avoid the ice bags and the nucleic acid specimens being directly in the same space, so as to prevent the ice bags from being contaminated and can be reused. The box body 1 is provided with a temperature monitoring device 10, which is used to monitor the temperature inside the specimen storage cavity and display the measured real-time temperature on the temperature display panel for medical staff to view. When the measured real-time temperature is higher than the set limit value, it can also give an alarm prompt to ensure that the temperature inside the specimen storage cavity meets the requirements. During the specimen transfer process, it is necessary to use a transfer cold chain box or add ice bags for refrigeration. The existing transfer cold chain boxes in major hospitals have the defects of heavy weight and small internal specimen storage space, resulting in affected specimen storage. Ice bags are directly placed inside the specimen transfer box, and the ice bags are in direct contact with the specimen box or specimen tube, and there is also a possibility that the ice bags may be contaminated by the specimens. Compared with the existing transfer boxes, the safety of the present invention is higher.

[0052] The box body 1 is provided with a first storage groove 11 for storing the specimen barcode summary form and a second storage groove 12 for storing disposable items. The first storage groove 11 and the second storage groove 12 are respectively located on the left and right sides of the box body 1. The first storage groove 11 is used to store the specimen barcode summary form, which can avoid the loss of the summary form. The second storage groove 12 is used to store disposable items, such as infection waste bags, gloves, spare sealing rolls 35, etc., and has a good classification storage function, which is convenient for medical staff to collect and check specimens. Existing specimen transfer boxes do not have a place to place the barcode summary form, which is likely to cause the loss of the summary form (each patient has their own corresponding barcode information, and every 10 barcodes are pasted on a table made of an A4 paper). The loss of the barcode summary form leads to the loss of the sampling patient information. If the patient information needs to be retrieved, it will greatly increase the workload of the sampling work and the testing staff, and affect the result reporting time.

[0053] A telescopic push-pull rod 13 is provided at the rear side of the box body 1, and wheels 14 are provided at the four corner positions of the bottom of the box body 1, which has good portability. In addition, a handle is provided in the middle of the top surface of the box cover 2. The front side of the box cover 2 is detachably connected to the box body 1 through a tower buckle, and the rear side of the box cover 2 is hinged to the box body 1, so that medical staff can choose to carry the transfer box by hand or by pushing and pulling according to actual needs.

[0054] The above description is a detailed description of the preferred feasible embodiment of the present invention, but the embodiment is not used to limit the patent application scope of the present invention. Any equivalent changes or modifications completed under the technical spirit prompted by the present invention shall fall within the patent scope covered by the present invention.
