Description

Technical Field

[0001] The utility model relates to the technical field of cell cryopreservation, in particular to a sleeve type cryopreservation tube. Background Art

[0002] At present, cryotubes are widely used in biomedicine and clinical medicine as an important storage tool. For biological cell samples, using cryotubes to preserve cells is a conventional cell preservation method in cell laboratories, and they are generally stored in a liquid nitrogen tank environment at -196°C. In order to record sample information, the sample information is generally printed or written on a label, and then the label is directly pasted on the outer wall of the cryotube. This label is the "identity mark" of this biological sample, so it is extremely important to protect the integrity of the label information. However, the existing cryotube design does not effectively protect the label. In order to prevent the shaking of the cryotube, most of the cryotubes are tightly fitted with the holes and grooves of the cryobox. It is very easy to scratch the label during the process of removing and inserting the cryotube. In another case, the label has poor adhesion and falls off into the liquid nitrogen tank in a low temperature environment or soaked in liquid nitrogen, making it difficult to retrieve. Even if the label is retrieved, if too many labels are dropped, it is impossible to determine the sample corresponding to the label. Therefore, there is an urgent need for a cryotube suitable for use in a liquid nitrogen tank that can prevent the label from being scratched or falling off and can protect the label information intact, so that the staff can fully identify the label information and avoid the label falling into the liquid nitrogen tank as much as possible. Utility Model Content

[0003] The utility model aims to provide a sleeve type cryopreservation tube with a protective label.

[0004] The technical scheme of the sleeve type cryopreservation tube of the utility model is: a sleeve type cryopreservation tube, comprising a tube cover, an inner tube and a sleeve.

[0005] Furthermore, a convex groove is provided on the upper edge of the inner circle of the top of the tube cover.

[0006] Furthermore, the outer side of the tube cover is provided with anti-slip teeth, and the inner side is provided with spiral patterns connected to the inner tube.

[0007] Furthermore, the outer side of the inner tube is provided with a spiral pattern A connected to the tube cover.

[0008] Furthermore, the inner tube is provided with a rubber ring.

[0009] Furthermore, the inner tube is provided with anti-slip teeth.

[0010] Furthermore, the inner tube is provided with a spiral pattern B.

[0011] Furthermore, the inner tube is provided with a groove for sticking a label.

[0012] Furthermore, the inner tube is provided with a base A which fits with the bottom of the sleeve.

[0013] Furthermore, the sleeve is provided with a spiral pattern C matching the spiral pattern B.

[0014] Furthermore, the sleeve is provided with a base B which fits with the bottom of the inner tube and is partially raised so as to be stably placed on a horizontal plane.

[0015] Furthermore, each of the components is made of PP polypropylene plastic material.

[0016] Furthermore, the diameter of the sleeve-type cryopreservation tube is 10 mm and the overall height is 90 mm.

[0017] The beneficial effect of the utility model is that the sleeve-type cryopreservation tube can effectively protect the integrity of the label. When the cryopreservation tube is taken out of the cryopreservation box, the label is prevented from being scratched due to the protection of the sleeve. At the same time, even if the label falls off, it only falls into the sleeve of the corresponding biological sample, avoiding the situation where the label falls off into the liquid nitrogen tank and is difficult to retrieve. Even if the label is retrieved, if too many labels are dropped, it is impossible to determine the sample corresponding to the label. BRIEF DESCRIPTION OF THE DRAWINGS
