Low temperature protection device and low temperature taking and placing system comprising same

Abstract

The invention discloses a low temperature protection device and a low temperature taking and placing system comprising same. The low temperature protection device comprises a wrapping body and a coldsupplying assembly; a containing cavity containing a freezing preservation pipe and an interlayer cavity located outside the containing cavity are included in the wrapping body; the interlayer cavitysurrounds the outer wall face of the containing cavity; one end of the wrapping body is provided with an opening which is communicated with the containing cavity; the cold supplying assembly is connected to the wrapping body and is communicated with the interlayer cavity; and the cold supplying assembly provides a cold source for the interlayer cavity. The low temperature taking and placing systemcomprises a taking and placing device and the low temperature protection device. The taking and placing device is connected to the wrapping body, and a taking and placing port of the taking and placing device is communicated with the containing cavity. According to the low temperature protection device and the low temperature taking and placing system comprising the same, it is achieved that thefreezing preservation pipe is wrapped in the profound hypothermia containing cavity through the cold supplying assembly, and it is effectively avoided that biological samples in the freezing preservation pipe are repeatedly frozen and thawed, and the activity of the biological samples is damaged.

Description

technical field [0001] The invention relates to a cryogenic protection device and a cryogenic pick-and-place system comprising it. Background technique [0002] The ultra-low temperature full cold chain suction device is a full cold chain suction device that sucks samples at low temperatures and ensures the activity of the samples. Most biological samples need to be stored in a deep low temperature environment, especially some cells used for storage and reinfusion into the human body. The biological samples need to be under cryogenic protection throughout the whole process to prevent the biological samples from being damaged by repeated freezing and thawing. [0003] It is difficult for the existing ultra-low temperature biological sample bank system to ensure that the temperature of the biological sample is not affected during the process of drawing biological samples. Taking the European patent EP2208951A2 as an example, when biological samples are drawn in a large -80°C ...
