Sample transfer device and method for controlling sample transfer device

Abstract

The invention relates to a sample transfer device and a control method of the sample transfer device, the sample transfer device is matched with a heat preservation cabin for use, the sample transfer device comprises a sealing assembly, wherein the sealing assembly comprises a sealing piece, and the sealing piece comprises a sealing plug and a sample container; a sealing assembly arranged on the driving assembly, wherein the driving assembly drives the sealing assembly to reciprocate in the first direction; and a lifting assembly connected with the driving assembly, wherein the lifting assembly moves in the second direction to lift the sealing plug or the sample container to the hatch of the heat preservation cabin, and the second direction is perpendicular to the first direction. According to the sample transfer device provided by the invention, when a biological sample needs to be stored, the driving assembly drives the sample container to move to the cabin opening of the heat preservation cabin, meanwhile, a sealing plug is moved to be separated from the cabin opening of the heat preservation cabin, and then the lifting assembly lifts the sample container into the cabin opening of the heat preservation cabin, so that rapid storage of the biological sample is realized; the environment in the heat preservation cabin is prevented from being damaged; a control system is matched to realize the function of automatically storing and taking samples, and the storage is efficient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sample transfer device and a control method for the sample transfer device. Background technique [0002] Most biological samples need to be stored in a deep cryogenic environment, and during access operations, they should also be under cryogenic protection to prevent repeated freezing and thawing of samples and damage their activity. Therefore, when operating samples, they need to be Put it in a well-sealed insulation cabin. [0003] At the same time, in order to realize the full cold chain protection of the samples, the samples are usually placed in small cryogenic containers for transshipment. When the samples are automatically stored and retrieved, the small cryogenic containers will be transferred to the insulation cabin together, and then the samples will be manipulated; however, due to The temperature inside the thermal insulation cabin is low, and the small cry...
