Study On The Washing Technology Of Freezing RBCs

There are twenty five percent of the wounded need to peremptorily cure for transfusion. It is the important ensure that provided sufficient blood to reduce death rate of wounded person. The data in existence indicate that the fresh blood could only been preserved for 42 days in 4℃. There is 1-3 times blood in the blood bank more than average dosage a day, these is far from satisfied demand of blood under wartime or emergencies. Freezing conservation is an effective method that could preserve red blood cells in long term (The effective conservation time is ten years ). Thus, a lot of freezing preserved (-80℃) RBCs should be provided as safe blood in time before cosmically blood mobilized under emergencies. The blood frozen can save time for blood reorganization, and can be more preponderant than routine blood conservation.The glycerol in freezing preservation RBCs has stated affect for flesh, and it should be wiped off from the RBCs thawed before transfusion. USA armies have been equipped corresponding equipment of dealing with RBCs. However, washing RBCs with imported washer and expendable is very costly and the washing program is very miscellaneous. In our country manual washing RBCs' process takes a lot of time. It needs about three hours to wash one unit RBCs. Aiming at this actuality, we make our purpose to develop a new type freezing RBC washer and appraised it's washing effect. So we could supply ensure of technique and equipment for fleet, safe, effective transfusion in the wartime.We explore 115 model and 215 model washer's program and own the intellectual property right of our new RBCs washer. In our study, the technique to preserve and wash freezing RBCs is set up, and a new type...
