[0002] The laboratory is a bridge between clinical medicine and basic medicine, including branch disciplines such as clinical chemistry, clinical microbiology, clinical immunology, hematology, fluidology, and blood transfusion. The laboratory needs to test various microorganisms, so microbial preservation tubes are needed in the laboratory to store the microorganisms to be tested and the microorganisms after testing, and the microorganisms need to be able to survive in the preservation tubes.

[0003] For example, the patent with application number CN212800347U discloses a microorganism storage tube for laboratory, including a box, a placement groove is provided on the upper surface of the box, connecting grooves are provided on both sides of the inner wall of the placement groove, and an ice box is provided at the bottom of the placement groove. Before using the microorganism storage tube for laboratory, personnel can put the storage tube on the rubber pad inside the drawer, then turn on the sterilization lamp, and then put the ice box into the box, the interior of the ice box contains refrigerant, and then put the medicine storage box into the box through the card block, and then take out the storage tube from the drawer, and place the microorganism in the storage tube, and through the small magnetic beads inside, the microorganism is adsorbed on the surface of the small magnetic beads, so that the storage tube can be temporarily stored in the medicine storage box, and due to the effect of the refrigerant, the death of microorganisms caused by excessive temperature can be avoided, and then after the sampling is completed, the medicine storage box can be taken out through the card block and placed in a refrigerated environment, so as to ensure the survival of the microorganism.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] Please pay attention to Figures 1 to 5 A microorganism storage tube for a laboratory comprises a storage tube 1 and a sealing plug 2, wherein the sealing plug 2 is installed inside the storage tube 1, an outer ring 11 is provided on the outer wall of the storage tube 1, a locking assembly 3 is provided on the outer ring 11, a tube cover 21 is provided on the upper end surface of the sealing plug 2, a cavity 22 is provided inside the sealing plug 2, and an aspiration assembly 4 is provided in the cavity 22.

[0028] Specifically, by providing the locking component 3, the ball 121 can be clamped in the groove 23 on the outer wall of the sealing plug 2, and the sealing plug 2 can be clamped in the storage tube 1, thereby improving the sealing of the storage tube 1, which is beneficial for the long-term preservation of microbial strains. In addition, by providing the suction component 4, the microbial suspension can be conveniently absorbed and injected into the storage tube 1. It is repeatedly blown to make the microbial suspension and the preservation liquid in the storage tube 1 fully merged, which can improve the survival of the microorganisms.

[0029] Please pay attention to Figure 2 , Figure 4 The locking assembly 3 includes a movable ring 31, an extrusion ring 32 is arranged inside the movable ring 31, and a conical notch 321 is formed inside the extrusion ring 32. The conical notch 321 formed inside the extrusion ring 32 can squeeze the ball 121 so that the ball 121 is stuck in the slot 23, thereby achieving the function of clamping the sealing plug 2.

[0030] A first spring 33 is disposed between the lower end of the extrusion ring 32 and the upper end of the outer ring 11, and the first spring 33 surrounds the outside of the storage tube 1. The first spring 33 can exert an upward force on the extrusion ring 32 and the movable ring 31, so that the extrusion ring 32 squeezes the ball 121.

[0031] The outer wall of the storage tube 1 is provided with a plurality of mounting holes 12, and movable balls 121 are arranged in the mounting holes 12. The movable balls 121 arranged in the mounting holes 12 can realize the function of locking and unlocking the sealing plug 2 as the movable ring 31 and the extrusion ring 32 move up and down.

[0032] The outer wall of the sealing plug 2 is provided with a plurality of inwardly recessed slots 23 , into which the balls 121 can be inserted. The design of the slots 23 allows the balls 121 to be installed, thereby achieving the function of clamping the sealing plug 2 .

[0033] Please pay attention to Figure 3 , Figure 5 The suction component 4 includes a movable disk 41 installed in the cavity 22, and a movable rod 42 is provided at the upper end of the movable disk 41. A pull block 421 is provided on the end surface of the movable rod 42 that passes through the tube cover 21. The pull block 421 can pull the movable rod 42 and the movable disk 41 to reciprocate. The reciprocating movable disk 41 can generate negative pressure in the cavity 22 to achieve the function of blowing and sucking the microbial suspension.

[0034] A second spring 411 is provided at the upper end of the movable disk 41, and the other half of the second spring 411 is fixedly connected to the inner top plate of the cavity 22, and the second spring 411 surrounds the movable rod 42. When suction and blowing are not performed, the second spring 411 can apply a downward force to the movable disk 41, so that the movable disk 41 seals the straw 43.

[0035] The suction assembly 4 further includes a suction tube 43 , which is mounted at the lower end of the sealing plug 2 , and the upper end of the suction tube 43 is inserted into the interior of the cavity 22 . The suction tube 43 can suck the bacterial suspension and blow the bacterial suspension.

[0036] The specific operation mode of the utility model is as follows:

[0037] When in use, first inject microbial preservation liquid into the storage tube 1, align the suction tube 43 with the microbial suspension in the culture dish, pull the pull block 421 upward, and the movable rod 42 and the movable disk 41 move upward synchronously. The movable disk 41 moving upward will cause negative pressure in the cavity 22 (as the movable disk 41 moves, the second spring 411 is squeezed), and the microbial suspension can be sucked into the suction tube 43 at this time, and then the suction tube 43 is aligned with the upper end of the storage tube 1, and the pull block 421 is loosened. The second spring 411 is no longer squeezed, so that the movable disk 41 is reset. As the movable disk 41 is reset, the microbial suspension in the suction tube 43 is automatically injected into the storage tube 1. After injection, the sealing plug 2 is inserted into the storage tube 1.

[0038] When inserting the sealing plug 2: first grasp the outer wall of the movable ring 31 and pull it downward so that the squeezing ring 32 no longer restricts the ball 121 in the mounting hole 12 (the first spring 33 will be squeezed at this time). At this time, align the sealing plug 2 with the upper end of the storage tube 1, and then push it into the storage tube 1 to install the sealing plug 2. When it is installed in place, loosen the movable ring 31. At this time, the first spring 33 is no longer restricted, so that the movable ring 31 moves upward. As the movable ring 31 moves, the squeezing ring 32 moves upward synchronously. When the conical notch 321 contacts the ball 121, the ball 121 will be pushed into the slot 23, thereby clamping the sealing plug 2. After clamping, repeatedly pull the pull block 421 again to blow the microbial suspension so that it can be fully integrated with the preservation liquid in the storage tube 1 to improve the survival of the microorganisms.

[0039] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
