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 in particular relates to a pneumatic blood collection system and a collection method of the pneumatic blood collection system. Background technique [0002] At present, the centrifugal and membrane filtration blood component collection equipment at home and abroad generally use peristaltic pumps to collect and return human blood when collecting blood components. The manufacturing process of peristaltic pumps is complicated and the technical requirements are high. The application level is uneven. The life of the silicone wheel of the peristaltic pump has always been a key factor determining the performance and life of the peristaltic pump and it is difficult to control. When the peristaltic pump peristaltic method collects blood, it is easy to cause blood cell rupture caused by extrusion and high temperature. Hemolysis, pipeline rupture caused by extrusion, blood pressure fluctuation of blood do...
