Low-temperature storage transfer device and operation method thereof

Abstract

The invention discloses a low-temperature storage transfer device and an operation method thereof. The low-temperature storage transfer device is used for conveying a transfer pot from the external environment to a refrigeration house and comprises a sealing component and a transmission component, wherein the sealing component comprises an inner door and an outer door; the inner door is provided with an inner lifting mechanism, the outer door is provided with an outer lifting mechanism, and a sealable buffer area is formed between the inner door and the outer door; the inner door is communicated with the refrigeration house, and the outer door is communicated with the external environment; the transmission component comprises an outer transmission mechanism and an inner transmission mechanism; the outer transmission mechanism is used for conveying the transfer pot from the external environment to the buffer area, and the inner transmission mechanism is used for conveying the transfer pot from buffer area to the refrigeration house. The low-temperature storage transfer device can ensure that a biological sample cannot be exposed in the normal-temperature environment after the transfer pot is uncapped, thereby reducing sample damage. The buffer area can prevent the inner part of the transfer pot from frosting, and the success rate of automatically storing and taking pipes is increased.

Description

technical field [0001] The invention relates to an automatic storage transfer device, in particular to a low-temperature storage transfer device and an operating method thereof. Background technique [0002] The development of life science research and the advancement of disease analysis, detection, treatment and health care technologies in the clinical medical field have promoted an increasingly extensive demand for biological samples, and also put forward higher requirements for storage technologies and equipment for biological samples, including storage The safety, reliability and stability of the sample, as well as the accuracy, efficiency and scientific requirements of the sample access process and procedures. The objects of biological sample storage often cover samples such as biological macromolecules, cells, tissues and organs, such as human organ tissues, whole blood, plasma, serum, biological fluids or processed biological samples (including DNA, RNA, protein, etc....

AI Technical Summary

Problems solved by technology

However, the ultra-low temperature automatic biological sample storage equipment in the prior art lacks a buffer operation space or mechanism in a low temperature environment with a certain temperature control function to transfer the biological sample (sample cryopreservation tube) from the low temperature transfer storage container to the ultra low temperature storage device. In the frozen storage container or space, take the European patent EP2666694A1 as an example, the transfer storage tank is transported on an open space track, and when it is about to enter the cold storage, the transfer tank cover is opened by the external cover opening mechanism, and then the transfer tank is reloaded. into the cold storage; although the scheme realizes automatic transmission, the biological samples will be exposed to the open environment for a period of time, which is easy to frost and affect the biological activity of the biological samples; More complicated, not conducive to large-scale promotion and application of equipment
