An automatic whole blood collecting and separating system

Abstract

The invention relates to an automatic whole blood collecting and separating system, which comprises a whole blood collecting and separating machine and a disposable whole blood collecting and separating device, the disposable whole blood collecting and separating device comprises a blood collecting device, a sampling bag, a bacterium filter, an anticoagulant line, an anticoagulant puncture device,an erythrocyte care fluid puncturing apparatus, a saline piercer, a suspended erythrocyte bag, a white blood cell filter, a white blood cell-removed suspended red blood cells bag, a pressure detectorconnector, a blood pump line, a centrifugal cup, a plasma bag, a cold precipitation spare bag and a waste liquid bag, wherein the whole blood collecting and separating machine comprises a maintenanceliquid pump, an anticoagulant pump, a blood pump, a centrifuge, a blood cell detector, a pipeline pressure detector, an anticoagulant air detector, a maintenance liquid air detector, a blood air detector, a plasma scale and a controller. The blood is automatically collected and separated into fresh plasma and suspend red blood cells (or washed red blood cells), the operation process is completedat one time, the collection and the separation preparation need not be completed in two steps, the cost is low, and the plasma quality and the shelf life after the whole blood is separated are guaranteed.

Description

technical field [0001] The invention relates to a blood collection and separation device, in particular to an automatic whole blood collection and separation system. Background technique [0002] Component blood transfusion is a new concept of blood transfusion developed in the past 20 years with the advancement of medical science and medical technology. The emergence and development of component blood transfusion is a milestone in the progress of modern blood transfusion. Component blood transfusion is significantly better than whole blood transfusion. Advanced countries in the world seldom use whole blood directly, and component blood transfusion has become the development direction of blood transfusion in the world today. Whole blood is used as raw blood for preparing various blood components, separated and prepared into various blood components, and then used in clinical patients; fresh plasma, suspended red blood cells (or washed red blood cells) and cryoprecipitate a...

AI Technical Summary

Problems solved by technology

[0006] The method of prior art, as described above: need many places (two places of blood collection and separation preparation), many labors (whole blood collection personnel and blood separation preparation personnel), multi-equipment (blood collection instrument, large-capacity centrifuge, blood component At the same time, the whole blood is transported from the blood collection room to the blood separation preparation room. Before the separation and preparation, the whole blood must be stored for several hours, which affects the quality of the blood components, even beyond the preparation of fresh frozen plasma and cold plasma.
