AI Technical Summary

Technical Problem

Cryopreservation bags are prone to frostbite when removed from low-temperature environments. Furthermore, cryopreservation bags have a large storage volume, high cell concentration, and long thawing time. They are inconvenient to handle when using antifreeze gloves, and it is impossible to control the complete thawing of cryopreservation bags by submerging them in water.

Method used

Design a clamp that clamps the side edge of the cryopreservation bag by closing the first clamping part and the second clamping part, and sets a hollow part to make room for the storage area, thereby improving clamping stability and reducing the risk of frostbite. The clamping part is driven to close and separate by the hand-held part, which simplifies the operation.

Benefits of technology

It improves the safety of moving and thawing cryopreservation bags, reduces the risk of frostbite, minimizes cell damage, and simplifies operation.

Abstract

The utility model discloses a clamp for cryopreservation bag, the clamp includes: first clamping part and second clamping part, and first clamping part is equipped with first hollow part, and second clamping part is equipped with second hollow part, and first clamping part and second clamping part can be along the first direction and separate, wherein, when first clamping part and second clamping part close, the first side edge and the second side edge of the opposite cryopreservation bag are clamped, and first hollow part and second hollow part let the storage area of cryopreservation bag be in place, and when first clamping part and second clamping part separate, the clamping of cryopreservation bag is released. According to the clamp of the utility model embodiment, when first clamping part and second clamping part close, the first side edge and the second side edge of the opposite cryopreservation bag are clamped, improve the stability of clamping cryopreservation bag, and the user moves cryopreservation bag, and reduce the risk of user's frostbite.
