Description

Technical Field

[0001] The present application relates to the technical field of freezing racks, and in particular to a freezing rack for sperm freezing tubes. Background Art

[0002] Sperm cryopreservation is an important part of human assisted reproductive technology, especially epididymal or testicular sperm obtained through surgery, and sperm specimens from patients with difficulty in sperm extraction are very precious in assisted reproductive treatment. At present, the commonly used freezing method in clinical practice is to mix semen with a cryoprotectant and place it in a cryotube, then wrap the cryotube with a rope and fix it on a freezing rack to prevent the cryotube from falling off in liquid nitrogen, suspend it in liquid nitrogen vapor and then put it into liquid nitrogen, and finally store it in a liquid nitrogen storage tank for a long time. When it is necessary to take out the freezing rack, it is necessary to untie multiple fixed ropes one by one, which makes it more troublesome to take it out.

[0003] Therefore, a freezing rack for frozen sperm tubes which is convenient for taking out is provided. Summary of the invention
