Intelligent biological sample storing and picking mechanism

Abstract

The invention discloses an intelligent biological sample storing and picking mechanism. The intelligent biological sample storing and picking mechanism comprises a receiving transfer system, a transfer system and a low-temperature storage system. The receiving transfer system can receive a cryopreservation tube and can transfer the received cryopreservation tube to a position A. The transfer system includes a tube picking assembly and a transfer assembly. A tube picking main member can drive the cryopreservation tube into or out of an operating channel of a low-temperature tube sleeve. The low-temperature storage system is provided with a positioning receiving member, and the positioning receiving member can position the receiving storage position of the cryopreservation tube in the low-temperature storage system. The transfer assembly can drive the tube picking assembly to grasp or suck the cryopreservation tube at the position A to transfer into the low-temperature storage system forstorage. No manual intervention is required, the cryopreservation tube does not need to be exposed to the normal temperature environment in the whole process, and the operation process does not affect the cryopreservation tube. By adopting the positioning receiving member, the cryopreservation tube can be stored accurately and quickly, trouble and labor are saved, and the environmental safety ofbiological samples is ensured.

Description

technical field [0001] The invention relates to the field of storage equipment for biological samples, in particular to an intelligent access mechanism for biological samples. Background technique [0002] The deep cryogenic biological sample bank is an important basic equipment for research work in the fields of medicine and biology. The low temperature storage of liquid nitrogen can keep biological tissues such as blood, stem cells and immune cells alive for a long time; the deep cryogenic storage systems in the prior art include: Two situations: One type of liquid nitrogen tank is stored in a manual operation structure. When selecting cryotubes, the operator needs to open the tank cover, reach into the tank body of the liquid nitrogen tank to select the target cryotube, because all liquid nitrogen tanks store A large number of different biological samples in cryopreservation tubes need to be manually selected for a long time, and the opening of the liquid nitrogen tank mu...

AI Technical Summary

Problems solved by technology

[0004] 1. When it is necessary to store the cryopreservation tubes in the liquid nitrogen tank, it is necessary to find a suitable storage point or directly extract the storage disk to a normal temperature environment, and store the cryopreservation tubes; this is time-consuming and labor-intensive. There are hidden dangers of damage to stored biological sample products; 2. It is necessary to expose the cryopreservation tube to the normal temperature environment first, and then grab it by the robot and transfer it to the liquid nitrogen tank, so that the biological samples in the cryopreservation tube will be affected during the transfer process ; 3. Due to the complex structure of the manipulator and the large occupied area, it is impossible to seal the manipulator in a closed environment for operation at the same time. Even if a sealing cover is added, it is very large and difficult to operate; 4. Multiple manipulator mechanisms are complicated and the cost is relatively high. high etc.;

[0005] For example, in the patent disclosed in the prior art, its publication number is CN107600859A: when it is necessary to store or extract the cryopreservation tubes of biological samples, the sample box provided with a plurality of cryopreservation tubes is first lifted to the In the operable area, the sample box is placed into the operable area inside the cryogenic storage tank through the first manipulator, and then the target sample box is transferred to the liquid nitrogen tank through the second manipulator; the patented technology of CN107600859A not only has the above problems, but also Multiple cryopreservation tubes are usually stored in the sample box, which further affects and destroys other cryopreservation tubes in the sample box during the access process.
