Description

Technical Field

[0001] The present invention relates to the technical field of sample storage, and particularly to a vertical low-temperature storage.

Background Art

[0002] In the field of biological sample storage, a low-temperature access device is used to store biological samples such as blood samples, vaccines, bacterial strains, and virus strains at low temperatures, and preserves their activity by always keeping the samples in a low-temperature state.

[0003] The low-temperature storage disclosed in Chinese Patent Application No. 20211110816 generally adopts a hinge-type opening and closing door in sample access, and completely exposes the low-temperature area on the back of the door by opening the entire door to perform the access operation of the low-temperature stored object. Frequent temperature changes have an adverse effect on the objects stored in the low-temperature area. Especially in the field of biological sample storage, biological samples are particularly sensitive to temperature changes, so it is easy to cause loss of activity. Therefore, the inventors designed a vertical low-temperature storage.

The observation window 993 allows observation of the operating status inside the control room 2, and the operation unit 994 can issue commands to display the internal status of the sample storage room 1.

[0069] Based on the above, in this invention, the transfer window 32 is linked to the winding storage member 33 and moves up and down to align with the corresponding storage groove on the basket in the sample storage chamber 1, causing the sample scooping mechanism 4 to move up and down, allowing it to pass through the transfer window 32 and scoop up the sample on the basket, thus avoiding exposure of other samples that do not need to be collected and reducing adverse effects on the samples in the sample storage chamber 1. By installing the gripping mechanism 5, the transfer tank storage section, and the scanning mechanism 6 in one location and moving the sample scooping mechanism 4 up and down on one side of the gripping mechanism 5, it becomes easier to grip, transport, and scan samples using the gripping mechanism 5, and a single gripping mechanism 5 can achieve free movement in multiple functional areas. By installing the heat-insulating isolation door 7, the shutter passage assembly 3 can be closed, and the inside of the sample storage chamber 1 can be kept warm. The sample scooping mechanism 4 enables sample access, prevents the sample from falling out during scooping and transfer, and allows the sample or plate holder to be pushed out and left after being transferred to a specific position.
