AI Technical Summary

Technical Problem

Existing cryopreservation boxes lack effective protective measures during transportation. Samples are easily loosened due to vibration, causing small samples to collide or be damaged. Furthermore, it is difficult to effectively distinguish between master samples and retest samples.

Method used

A cryopreservation box was designed, comprising a box body, a lid, and side strips. An internal partition divides the box body into two connected chambers. One chamber is used to hold hematopoietic stem cell cryopreservation bags, and the other chamber is used for sample re-examination. It is equipped with a snap-fit ​​structure and an elastic sealing gasket, and has an observation structure to reduce the number of times the lid is opened and the risk of contamination.

Benefits of technology

This technology enables the effective storage and management of hematopoietic stem cells and their retest samples, improving the safety and efficiency of preservation, ensuring that sample quality is not affected, and reducing the risk of damage.
