Description

Technical Field

[0001] This utility model relates to the field of equipment for stem cell preparation, and in particular to a protective box for stem cell blood bags. Background Technology

[0002] Hematopoietic stem cell samples refer to a mixture of hematopoietic stem cells, white blood cells, and platelets after the removal of plasma and red blood cells. The isolated hematopoietic stem cells are packed into cryopreservation bags, which are then placed in protective cases and preserved in liquid nitrogen. Currently used protective cases typically employ a hinged connection between the box body and lid. However, the low temperature makes opening the case difficult when removing it from liquid nitrogen. Furthermore, this type of case does not secure the blood bag, allowing it to move within the case during transfer, potentially causing damage. Utility Model Content

An L-shaped insert plate 21 is fixed at the other end of the springs 20. The outer end of the L-shaped insert plate 21 is inserted into the insertion port. A pair of waist-shaped holes 22 are provided on the L-shaped insert plate 21. A limiting pin 23 passes through the waist-shaped holes 22. A limiting plate is provided at the lower end of the limiting pin 23. The limiting plate is located on the lower side of the L-shaped insert plate 21.

[0020] In this embodiment, the blood bag is placed in the placement cavity of the lower box 1, and then the lid 3 is placed on the upper end of the lower box 1. When placing the lid, the L-shaped fittings 30 are fitted onto the four corners of the lower box 1. During the fitting process, the L-shaped inserts 21 are pressed inward one by one so that the lower end of each L-shaped fitting 30 extends out of the bottom of the lower box 1. Then, the pressing on the L-shaped inserts 21 is released, and the L-shaped inserts 21 are then inserted into the insertion port. The bag is then placed in a liquid nitrogen container for preservation.

[0021] In this embodiment, when removing the blood bag, the L-shaped insert 21 is pressed inward to move it out of the insertion port.
