Plasma storage system for low-temperature environment

Abstract

The invention provides a plasma storage system for a low-temperature environment. The plasma storage system comprises a refrigeration storage body, multiple sets of shelves, a scanning device, multiple manipulators and a storage operation device; the manipulators are positioned between the two sets of shelves; multiple plasma trays are arranged on the shelves; plasma bags with plasma can be placedon the plasma trays; the scanning device is used for scanning information of the plasma bags; the storage operation device is used for controlling the plasma storage system to store or take out the plasma bags; the manipulators comprise movable control mechanisms, rotary control mechanisms and taking mechanisms; the movable control mechanisms are connected with the rotary control mechanisms; thetaking mechanisms are connected with the rotary control mechanisms; the movable control mechanisms control the rotary control mechanisms and the taking mechanisms to move in length directions and height directions of the shelves; the rotary control mechanisms control the taking mechanisms to rotationally move; the taking mechanisms are provided with fork jaws capable of extending; and the plasma bags can be supported by the fork jaws. The plasma storage system can store single plasma bags, and is high in operation speed, stability and precision.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a plasma storage and withdrawal system used in a low temperature environment, especially a plasma storage and withdrawal system in a low temperature environment of minus 30 degrees. Background technique [0002] Plasma is stored in a blood bank and kept by medical institutions or the Red Cross. When blood transfusion is needed, the plasma is taken out of the blood bank. Due to the uncertainty of the use of plasma, the preservation of plasma has become a necessary task. [0003] In order to ensure the quality of plasma, plasma needs to be stored in a low temperature environment (usually below -20°C) in many cases. In the prior art, a cold storage with a working temperature below -20°C is usually established, and a blood bag storage rack and a blood bag storage frame placed on the blood bag storage rack are arranged in the cold storage. When people store plasma, they first put f...

Problems solved by technology

At present, the industry uses radio frequency scanning equipment to cooperate with manual blood bag storage and retrieval work, but the cost of using radio frequency scanning equipment is high. In the working environment of -20 ° C, it is easy to frost into ice, and the image scanning equipment is due to the distortion of the barcode. And error-prone, electromagnetic radio frequency scanning equipment is often error-prone due to inconsistent thickness of frost or too thick local ice
