Abstract

A method and equipment for preparing the red blood cells from blood through separating plasma from blood cells, washing, freezing, thawing and removing glycerin are disclosed. The combined liquid supplying device is hung above the blood taking bag with filter for gravitationally adding liquid to the blood taking bag. A sealed negative-pressure box containing plasma bag and waste liquid bag and communicated to vacuumizing pump is positioned at the lowest layer.

Description

technical field [0001] The invention relates to a method and a device for preparing washed red blood cells and freezing and thawing glycerol-free red blood cells, belonging to the technical field of blood separation and preparation of products thereof. Background technique [0002] At present, the process of separating plasma and washing blood cells adopts methods such as siphoning after centrifugation or squeezing with separating clips to remove the supernatant, which may easily cause contamination and loss of blood cells. The required equipment and environmental requirements are strict, and it is not suitable for operation in hospital blood banks. The cost of washing red blood cells prepared by this method is high, and the storage period is very short. The preparation of frozen and thawed glycerol-free red blood cells requires repeated centrifugation and washing processes, which are more likely to be polluted and have a shorter storage period. Clinical application of glyce...
