Exhausting method applied to automatic blood component separator

Abstract

The invention discloses an exhausting method applied to an automatic blood component separator. The exhausting method is used for carrying out exhausting work on blood serum obtained by whole blood separation; the automatic blood component separator at least comprises a blood serum bag hanging arm, a front extruding plate and a heat sealing head; the exhausting method mainly comprises the following steps: manufacturing a series of blood serum bags with different weights; operating the automatic blood component separator in sequence to extrude the blood serum bags with different weights, which are suspended on the blood serum bag hanging arm, through the front extruding plate until all air in the upper part is exhausted and the blood serum in the blood serum bags is raised to a triangular connector of a triplet blood bag; checking and recording a front extruding plate movement distance corresponding to each of the blood serum bags with different weights through software of the automatic blood component separator; programming specifications and types corresponding to the blood serum bags, the weights of the blood serum bags and the front extruding plate movement distances corresponding to different weights into a program and introducing the program into software; directly calling the program to control the front extruding plate to automatically finish exhausting work in an actual application process according to the specifications and types of the blood serum bags and the weights of the blood serum bags.

Description

technical field [0001] The invention relates to a gas removal method, in particular to an exhaust method applied to an automatic blood component separator. Background technique [0002] Component blood transfusion usually adopts 200ml or 400ml triplet blood bag containing blood collection bag, plasma bag and maintenance fluid bag for blood collection, and the whole blood collected in the blood collection bag is separated by automatic blood component separation machine The method usually used by automatic blood component separators to separate plasma is: squeeze the centrifuged blood collection bag through its extrusion device, so that the upper plasma in the blood collection bag enters the empty plasma bag. The air in the upper layer of the bag enters the plasma bag. On the other hand, there is usually a small amount of air in the plasma bag. Therefore, the air volume in the finished plasma bag finally obtained after separation is further increased. As we all know, the boil...

Problems solved by technology

As we all know, the boiling point of air is much lower than minus 100 degrees Celsius, and plasma is usually stored at minus 20 degrees Celsius. When plasma is frozen at minus 20 degrees Celsius, the air in the plasma bag is still in a gaseous state, and the air in the gaseous state causes the inside of the frozen plasma bag to freeze. There are air bubbles and it is easy to cause the plasma bag to rupture at the positi
