Abstract

The invention discloses a pneumatic type blood collecting system, and relates to the field of medical instruments and apparatuses. The pneumatic type blood collecting system comprises a puncture needle, a three-way connector, a blood filter, an anticoagulant puncture outfit, a blood donor pressure detecting connector, a saline solution puncture outfit, a blood component separator, a blood component collecting container, a system pressure detecting connector, a system pressure detector, a pressure buffering device, an air pump and a main controller. The invention further discloses a use method of the pneumatic type blood collecting system. The defects that when blood is collected by a peristaltic pump in a peristalsis mode, blood cell rupture caused by extrusion, hemolysis caused by high temperature, pipeline rupture caused by extrusion, high blood donor blood pressure fluctuation caused by peristalsis, complicated operation and the like are easily generated can be overcome, the running reliability of the blood component collecting device can be improved, the blood collecting safety is ensured, and the comfort of a blood donor is improved.

Description

Technical field [0001] The invention belongs to the field of medical devices, and specifically relates to a pneumatic blood collection system and a collection method of the pneumatic blood collection system. Background technique [0002] At present, centrifugal and membrane filtration blood component collection equipment at home and abroad generally use peristaltic pumps to collect and return human blood during blood component collection. The manufacturing process of peristaltic pumps is complicated and the technical requirements are high. Peristaltic pumps of various manufacturers The application level is uneven. The life of the peristaltic pump silicone wheel has always been a key factor in determining the performance and life of the peristaltic pump, but it is difficult to control. The peristaltic pump is prone to rupture of blood cells caused by extrusion and high temperature when collecting blood. The shortcomings of hemolysis and squeeze-induced pipeline rupture, large fluc...
