Biological sample vitrified cryopreservation device

A technology of vitrification and cryopreservation of biological samples, which is applied to the preservation, application, and animal husbandry of human or animal bodies. It can solve the problems of prolonging the time of manually searching for samples, cross-contamination of samples, and finding samples, so as to reduce manual search for samples time, reduce cross-contamination, and reduce the effect of sample exposure

Problems solved by technology

[0003] In addition, the existing cryopreservation rods are in a semi-closed state, and there is a risk of sample cross-contamination
At the same time, when the sample is thawed, due to the influence of the steam above the liquid nitrogen, the surface of the support rod is frosted, covering the marks on the support, making it impossible to quickly find the sample from a bucket, prolonging the time for manual search for samples

Embodiment Construction

[0034] Combine below Figure 1 to Figure 7 , the present invention is further described:

[0035] The biological sample vitrification and freezing storage device of the present invention includes a sample loading mechanism and a storage mechanism, the sample loading mechanism is used to load biological samples, the storage mechanism is used to store multiple pieces of the sample loading mechanism, and the multiple storage mechanisms stack Place in the liquid nitrogen tank to increase the storage capacity of biological samples.

[0036] Specifically, as figure 1 and figure 2 As shown, the sample loading mechanism includes a cryopreservation tube 1, a cryopreservation loading rod 2 and a tube cover 3; one end of the freezing storage loading rod 2 is fitted with the bottom of the tube cover 3, and the other end of the freezing storage loading rod 2 is used for loading samples. The thin slice tip 21, the cryopreservation tube 1 and the tube cover 3 are screwed together, so tha...

Abstract

The invention relates to a biological sample vitrified cryopreservation device. The biological sample vitrified cryopreservation device comprises sample loading mechanisms and storage mechanisms. Thesample loading mechanism is used for loading a biological sample and the storage mechanism is used for storing the sample loading mechanisms. The storage mechanisms are stacked in a liquid nitrogen tank so that the storage amount of biological samples is increased. The biological sample vitrified cryopreservation device solves the problem that the existing cryopreservation device is a slender plastic rod and can only store a layer of samples so that the storage space of the liquid nitrogen tank is occupied in a large amount. The biological sample vitrified cryopreservation device is easy to operate, can fast position a sample, can prevent embryo confusion and can reduce the risk of pollution.

Description

technical field [0001] The invention relates to a biological sample preservation device, in particular to a biological sample vitrification freezing storage device. Background technique [0002] At present, in the field of assisted reproduction, frozen embryos or oocytes are mainly stored in laboratories for cryopreserved straws and frozen straws. As described in Chinese patent document CN 106489914A, the cryo-loading rod is a slender plastic rod with non-equal diameters, the thin end is close to the tip of the slice, and is used for loading samples, and the thick and short end is the hand-held end. The straw is an elongated hollow plastic rod. One end is connected to the loading rod for loading samples, and the other end is a cotton-containing veil for filtering and a steel ring to prevent floating in liquid nitrogen. In this way, the frozen straw is used with the frozen straw. Since both are slender plastic rods, only one layer of samples can be stored, which takes up a ...
