[0002] Bone marrow biopsy samples are the "gold standard" samples for diagnosing blood diseases, hematopoietic system abnormalities and other diseases. The pollution-free and integrity of the storage process directly determines the accuracy of subsequent analysis results such as pathological detection and gene sequencing.

The rotating component includes an external toothed ring 14 that is rotatably connected to the outer wall of the top cover 5.

A driving component is provided inside the tank body 1. The driving component can sense the position of the storage tube 4 and drive the external toothed ring 14 to rotate relative to the storage tube 4.

[0021] Please see Figures 3-10 The control components shown in the figure also include a first sealing ring 21 installed inside the top cover 5. A lifting groove 22 is provided inside the top cover 5. The lifting groove 22 is annular. A lifting ring 23 is slidably connected in the vertical direction inside the lifting groove 22. The bottom surface of the first sealing ring 21 is fixedly connected to the top surface of the lifting ring 23. A second threaded rod 24 is rotatably connected inside the top cover 5.

A second rack 20 that can mesh with the outer toothed ring 14 is fixedly connected to the inner wall of the tank body 1. Both the first rack 19 and the second rack 20 are arc-shaped.

[0022] Please see Figures 1-5The storage mechanism shown in the figure also includes a fixed rod 28 fixedly installed on the upper side of the rotating column 2. A fixed plate 29 is fixedly connected to the fixed rod 28. The outer wall of the fixed plate 29 is rotatably connected to the inner wall of the tank body 1. A first through hole 30 and a second through hole 31 are opened on the top plate 18. Multiple sets of third through holes 32 are evenly opened on the fixed plate 29. A positioning groove 33 is opened inside the storage tube 4. Multiple sets of device grooves 34 connected to the storage groove 3 are opened inside the rotating column 2. A top rod 35 is slidably connected in the vertical direction inside the device groove 34. A spring 36 fixedly connected to the device groove 34 is fixedly connected to the top rod 35. The top surface of the top rod 35 can fit against the bottom surface of the storage tube 4. A cover plate 40 is hinged on the top plate 18. A sterilization lamp 41 is provided on the cover plate 40. A transparent plate 42 is fixedly connected to the side of the tank body 1.

[0023] Working principle: Open the cover plate 40, insert the storage tube 4 through the second through hole 31 into the third through hole 32 and fix it inside the storage tank 3. The temperature, humidity and other parameters required for sample storage can be set inside the tank 1 to ensure stable sample storage. Rotate the rotating column 2 to drive the storage tube 4 to rotate, and rotate the empty storage tank 3 to the position corresponding to the second through hole 31 in turn. Insert the empty storage tube 4 into the storage tank 3 one by one. After storage is completed, close the cover plate 40, and then start the sterilization lamp 41 to disinfect and sterilize the top cover 5 of the storage tube 4. When storing bone marrow samples, a set of empty storage tubes 4 are rotated to be directly below the first through hole 30. At this time, the first rack 19 drives the outer gear ring 14 to rotate. The outer gear ring 14 drives the rotating ring 15 to rotate the bevel gear ring 16. The bevel gear ring 16 drives multiple sets of first bevel gears 17 to rotate the first threaded rod 13. The first threaded rod 13 drives the sliding block 12 to make the fixing plate 10 slide towards the first bevel gear 17 in the sliding groove 11, thereby pulling open the perimeter of the rubber cap 8. Because the rubber cap 8 has a certain elasticity, the thickness is reduced during the opening process. The pressure on the delivery port 9 will decrease, and the delivery port 9 in the middle will gradually open, reducing the pressure on the delivery port 9 and making it easier to insert the tip of the bone marrow biopsy needle through the delivery port 9 for sample delivery. At the same time, the inner wall of the rubber cap 8 will tightly fit the outer wall of the biopsy needle, preventing a large amount of air from entering the storage tube 4 and also preventing impurities adhering to the outer wall of the biopsy needle from entering the storage tube 4. After the sample is delivered, the biopsy needle is withdrawn, and the delivery port 9 will close to a smaller state under the elastic force of the rubber cap 8. Then, continue to rotate the rotating column 2 to drive the... The storage tube 4 at this position continues to rotate, the outer toothed ring 14 disengages from the first rack 19 and gradually engages with the second rack 20. The toothed blocks of the second rack 20 face opposite directions to the toothed blocks of the first rack 19, causing the rotation direction of the outer toothed ring 14 to change. The reverse rotation of the outer toothed ring 14 can drive the first bevel gear 17 and the first threaded rod 13 to rotate in the opposite direction, thereby causing the sliding block 12 and the fixed plate 10 to slide and close towards the center synchronously, gradually generating a pushing force towards the center on the periphery of the rubber cover 8, squeezing and sealing the conveying hole 9, and completing the covering operation.

[0024] As the thickness of the cap 8 decreases during the process of being pulled open, the gap between the top and bottom sides of the cap 8 and the storage cavity 7 widens. At this point, the first sealing ring 21 is installed. During the rotation of the first threaded rod 13, the second bevel gear 26 drives the third bevel gear 27 to rotate the second threaded rod 24. This causes the lifting ring 23 to move upward through the threaded hole 25, pushing the top surface of the first sealing ring 21 against the bottom surface of the cap 8, tightly sealing the top of the cap 8 against the upper wall of the storage cavity 7, improving the sealing performance of the top and bottom sides of the cap 8. When the second threaded rod 24 rotates in the opposite direction... The rubber cap 8 is pushed to close, and its thickness gradually increases. At this time, the second threaded rod 24 will also rotate in the opposite direction, lowering the lifting ring 23 and the first sealing ring 21 to achieve the function of synchronous control. After the sample input is completed, a circular label sticker can be pasted on the top cover 5 to help seal the top cover 5. At the same time, the preliminary information of the sample can be noted on the sticker to facilitate sample differentiation and retrieval. The cover plate 40 is closed and the latch is locked to keep the tank 1 sealed. Afterwards, the upper side of the cover plate 40 and the first through hole 30 and the second through hole 31 can be initially disinfected by the sterilization lamp 41 to avoid bacterial interference during the opening process.

[0025] When a sample needs to be removed, the storage tube 4 can be rotated to the position of the second through hole 31, and the bottom push rod 35 can be pushed out of the storage tube 4 through the second through hole 31. The sample condition inside the container 1 can also be observed through the transparent plate 42. At this time, the cap 8 of the removed storage tube 4 is still tightly closed. When a sample needs to be extracted, the threaded sleeve 38 can be unscrewed in a sterile laboratory, and the sample can be taken out from the positioning groove 33 of the storage tube 4. Since sample collection is generally carried out in environments with frequent air circulation, such as wards, the content of dust, bacteria and other impurities in the air is relatively high. However, the testing is generally carried out in a relatively clean environment. Inside the bacterial laboratory, the top cover 5 can be opened directly to retrieve the sample for testing. Since the biopsy needle is used to extract columnar bone marrow samples, its size is relatively large. The rubber sealing cap at the top of the traditional vacuum blood collection tube is difficult to penetrate, and the hole produced after penetration is large. The rubber sealing cap itself is difficult to reset and close. This rubber sealing cap is only suitable for collecting and sealing fluid samples with thinner needles. For solid samples with relatively large volume, the auxiliary structure in this solution can be used to assist in opening and closing the rubber cap 8, improving the sealing performance while enabling flexible opening and closing of the delivery hole 9, ensuring the cleanliness of the sample.
