Problems solved by technology
[0003] Most of the existing low-temperature storage and retrieval devices are manually involved. Through some structures, the trays or storage racks storing biological samples are moved to the top opening of the tank, and are manually selected. When storing, the entire tray needs to be picked up so that adjacent The biological samples are in the outside world. If the frequency is too high, it will interfere with the adjacent biological samples, causing the biological samples to thaw repeatedly and lose their due activity. At the same time, artificial selection will also be damaged by internal nitrogen frostbite. , nitrogen continuously emerges from the opening, which increases energy loss, and at the same time, the efficiency of manual selection is low

Embodiment Construction
[0035] The present invention will be further described below with reference to specific embodiments and drawings. In the following description, more details are explained in order to fully understand the present invention. However, the present invention can obviously be implemented in many other ways than the description here. Those skilled in the art can make similar promotion and deduction according to actual application conditions without violating the connotation of the present invention. Therefore, the content of this specific embodiment should not limit the protection scope of the present invention.
[0036] Such as Figure 1-7 As shown, the present invention provides a small unitized biological sample access device in a low-temperature environment, including: a tank body 1, a storage unit 2, an air duct 3, a liquid nitrogen storage tank 4, a first servo motor 5, and an access mechanism 6. ;
[0037] Such as figure 1 As shown, the top of the tank body 1 is provided with a fl...

The invention belongs to the technical field of low-temperature access of biological samples, and particularly relates to a small unitized biological sample access device for a low-temperature environment. The device comprises a tank body, storage units, air guiding tubes, a liquid nitrogen storage box, a first servo motor and an access mechanism; each octagonal storage unit is formed by arrangingsingle storage boxes in a circular array, so that a single biological sample can be stored in each single storage box; when the sample is taken out or stored, all that is needed to take out the sample is to open the single storage box, thereby reducing energy consumption; at the same time, when the sample is taken out or stored, air guiding holes are completely blocked by baffle plates, so that the energy consumption loss is further reduced. The invention aims at providing the small unitized biological sample access device for the low-temperature environment, which reduces manual operation, automates the entire access mechanism, reduces certain energy consumption loss and avoids damage to biological samples from repeated frost melting.
Description
Technical field [0001] The invention belongs to the technical field of low-temperature access to biological samples, and particularly relates to a small-unit biological sample access device in a low-temperature environment. Background technique [0002] Cryopreservation is a necessary process to maintain the integrity of biological materials during long-term storage. A sufficiently low temperature environment can effectively stop the function of the biological sample and enable the biological sample to maintain its own activity for a long time. [0003] The existing low-temperature storage and retrieval devices are mostly manual. Through some structures, the tray or storage rack for storing biological samples is moved to the top opening of the tank, and the selection is performed manually. The entire tray needs to be picked up during storage to make adjacent The biological samples are in the outside world. If the number of times is too large, it will interfere with the adjacent bio...
