Microprocessor-based automatic-control intelligent bioactive material storage device

Abstract

The invention discloses a microprocessor-based automatic-control intelligent bioactive material storage device, which solves the problems of waste of liquid nitrogen due to short actual storage time of biomaterials, risk of contamination of biomaterials due to the fact that liquid nitrogen is not treated when being injected into storage devices, and shortening effective storage time of biomaterials due to exposure of biomaterials out of the liquid level of liquid nitrogen due to volatilization of liquid nitrogen during long-term storage. The microprocessor-based automatic control intelligent bioactive material storage device comprises a storage box body, a bottom cover, a pipe cavity, a liquid level meter, a solenoid valve and a microprocessor, wherein the top of the storage box body is provided with a liquid nitrogen spraying pipe which is connected with an external liquid nitrogen storage pipe and capable of spraying liquid nitrogen to the interior of the storage box body at regulartimes, the liquid nitrogen spraying pipe is in an annular shape, two or more liquid nitrogen spraying holes are formed in the liquid nitrogen spraying pipe equidistantly, and a sterile filter membranecolumn is arranged in the storage box body and positioned between the liquid nitrogen spraying pipe and the top of the pipe cavity. The microprocessor-based automatic-control intelligent bioactive material storage device has the advantage of simple structure, scientific and reasonable design, convenient use and cost saving, and can effectively eliminate the risk of stored biological materials being contaminated.

Description

technical field [0001] The invention relates to a microprocessor-based self-control intelligent bioactive material storage device. Background technique [0002] Storage devices used to store biological materials generally need to store biological materials in a low-temperature environment. The current ideal medium for manufacturing low-temperature environments generally uses liquid nitrogen. In the prior art, sufficient liquid nitrogen is generally injected into the storage device containing biological materials. Nitrogen, but because the time for taking biological materials is not fixed, the storage device is generally filled with liquid nitrogen, which will cause waste of liquid nitrogen, and the liquid nitrogen is directly injected into the storage device without treatment, so there will be biological contamination The risk of materials, in the prior art, it often occurs that the liquid nitrogen is not added in time, causing the biological materials in the storage device ...
