Description

Biological sample cryopreserving pipe

Technical Field

The utility model relates to a medical treatment auxiliary instrument technical field, concretely relates to biological sample cryopreserved pipe aims at storing biological sample better, reduces biological sample damage and information loss, reduces pathology technician and medical scientific research personnel's the operation degree of difficulty, ensures to develop research such as human disease prediction, diagnosis, treatment smoothly.

Background

The biological sample mainly refers to surgical excision of tissues, stem cells, whole blood, blood plasma, blood serum, DNA, RNA, biological body fluid and the like, and mainly comes from patients with different diseases in China, so that the integrity and stability of the biological sample are guaranteed to be vital to diagnosis, treatment and research of the diseases. Therefore, to reduce the damage to biological samples, we typically place them in a cryopreservation tube for long term storage in a liquid nitrogen tank.

Liquid nitrogen is a colorless, odorless, extremely low temperature liquid, and its temperature is-196 deg.C at normal pressure. Cryopreservation tubes are currently common devices for storing biological samples. At present, a biological sample is mainly placed in a tube of the freezing tube, and a tube cover is screwed and placed in liquid nitrogen for long-term storage. However, during long-term low-temperature storage, the joint between the tube cover and the tube wall of the freezing tube may gradually loosen, resulting in liquid nitrogen entering the freezing tube. This may cause a number of inconveniences:

firstly, a plurality of biological samples are stored in one liquid nitrogen tank, liquid nitrogen enters a freezing storage tube to contact with the biological samples and then floats in the liquid nitrogen tank, so that liquid nitrogen pollution can be caused, cross contamination among the biological samples is further caused, and the follow-up disease diagnosis and treatment research results are inaccurate.

Secondly, part of biological samples need to be stored aseptically for a long time, such as stem cells and the like, in the storage process, a layer of sealing film is wrapped on a bottle opening after a bottle cap is screwed down, the bottle opening is protected, so that the biological samples in the tube are prevented from being polluted, but the sealing film becomes fragile and is not tightly attached at low temperature for a long time, and the pollution probability of the bottle opening is greatly increased.

Moreover, the marks marked on the surface of the cryopreservation tube fall off due to the fact that the marks contact with organic solvents such as alcohol and the like in the operation process, so that information of the biological sample is lost, and the difficulty of research work is greatly increased. In clinical medicine, biological samples are extremely precious, and if damaged or lost, it will be a significant loss.
