Description

Technical Field

[0001] This utility model relates to the field of stem cell cryopreservation tube protection technology, specifically to a stem cell cryopreservation tube protective sleeve. Background Technology

[0002] Stem cell technology has become a breakthrough for humanity in overcoming various intractable diseases this century, and has been ranked first among the top ten scientific achievements by the American journal *Science* for two consecutive years. Currently, stem cells widely used in clinical practice include umbilical cord blood stem cells, mesenchymal stem cells, and neural stem cells. These stem cells are not only used in the clinical treatment of various hematologic, immune system, and nervous system diseases, but are also beginning to be widely applied in regenerative medicine, including the clinical treatment of various diseases such as tumors, heart disease, ophthalmological diseases, diabetes, orthopedic surgery, and brain and spinal cord injuries.

[0003] A Chinese utility model patent, application number CN201520257828.5, discloses a protective sleeve for stem cell cryopreservation tubes. This sleeve can be directly fitted onto existing cryopreservation tubes without modification, and damage to either the cryopreservation tube or the protective sleeve does not affect the use of the other. Furthermore, it incorporates a rubber stopper for better sealing. The design includes a tube cap with a lower opening and a base with a cylindrical groove at the upper end. A first rubber sleeve is attached to the side wall of the cylindrical groove. Multiple vertical connectors are fixed at circumferential intervals around the cylindrical groove at the upper end of the base. The other end of each connector is fixed to the lower end of a vertical connecting sleeve positioned above the base. A second rubber sleeve passes through the connecting sleeve, which has external threads. An annular fold extends outward from the lower end of the connecting sleeve, with a sealing gasket on its upper surface. An internal thread mates with the external threads on the inner side of the bottom opening of the tube cap, and a rubber stopper that tightly fits the opening of the cryopreservation tube is located at the top of the tube cap opening.

[0004] Although the aforementioned patent seals the stem cell cryopreservation tubes, the purpose of the stem cell cryopreservation tube protective sleeve is to protect the stem cell cryopreservation tubes. The existing protective sleeves cannot provide cushioning for the stem cell cryopreservation tubes. When the stem cell cryopreservation tubes are dropped or bumped during transportation, the protective sleeves cannot protect the stem cell cryopreservation tubes, resulting in damage to the stem cell cryopreservation tubes. And the stem cell cryopreservation tubes may be contaminated with bacteria or other biological contaminants due to the damage. Utility Model Content

[0030] like Figure 3 The elastic components 4 are arranged in an array with the central axis of the protective cylinder 1 as the axis. Multiple elastic components 4 can increase the protective force of the elastic components 4 and increase the effect of buffering and reducing impact.

[0031] In specific implementation of this utility model, such as Figure 2 and Figure 3 As shown, a locking post 11 is installed on the inner side of the top cover 2 near the protective cylinder 1, and a limiting groove 12 for use with the locking post 11 is installed on the end of the protective cylinder 1 near the top cover 2. During installation, the top cover 2 moves downward and rotates in the limiting groove 12 through the locking post 11, so that the top cover 2 is locked on the protective cylinder 1. The elastic component 4 acts as a buffer when locking, and after locking, it limits the upper and lower ends of the stem cell cryopreservation tube in the protective cylinder 1 to prevent the stem cell cryopreservation tube from shaking.

[0032] A locking observation hole 13 is provided on the outer side of the top cover 2.

[0033] A buffer layer 14 is provided inside the protective cylinder 1, which serves to protect and buffer the material.

[0034] The working principle of this utility model:

[0035] The stem cell cryopreservation tube is inserted into the protective cylinder 1. The top cover 2 moves downward and rotates within the limiting groove 12 via the locking pin 11, so that the top cover 2 is locked onto the protective cylinder 1. The elastic component 4 acts as a buffer when locking, and after locking, it limits the upper and lower ends of the stem cell cryopreservation tube in the protective cylinder 1. The two elastic components 4 limit the ends of the stem cell cryopreservation tube.

[0036] The present invention and its embodiments have been described above.
