Abstract

The invention belongs to the field of medical instruments, and particularly relates to an improved structure of a cryopreserved tube. The improved structure comprises a tube body and a tube cap, wherein the tube cap is connected with the tube body in an inner rotating manner; the tube cap is provided with an external thread; a tube opening of the tube body is provided with an internal thread; the internal thread is an internal thread section or an internal thread point provided with a notch therebetween. The cryopreserved tube provided by the invention is good in sealing effect, does not influence the pouring of substances inside the tube, is easy to screw, high in strength, has a mark classification function, saves the material, and is low in manufacturing cost.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to a cryopreservation tube, in particular to an improved structure of the cryopreservation tube. Background technique [0002] Cryopreservation tubes are often used in biology or medicine for cryogenic storage of cells or other substances. The cryotubes on the market are poorly sealed, causing the contents inside to be contaminated or leaked, and the tube body is easy to crack after being subjected to low temperature. The Chinese invention patent with the patent number CN102845414 disclosed a structure of a cryopreservation tube on January 2, 2013, including a tube body and a tube cover, the tube cover is mounted on the tube body, and the tube cover includes a center circle, surrounding ring surface, center downward convex structure, the top ring structure of the nozzle of the pipe body is embedded in the annular gap formed by the central downward convex structure and the surrounding ri...
