Abstract

The invention relates to the technical field of medical apparatuses, in particular to a pneumatic type blood collecting system which comprises a laser blood collector. The output end of the laser blood collector is connected with one end of a flow dividing pipe through a pipeline. The other end of the flow dividing pipe is connected with a mixing mechanism. The mixing mechanism is connected with the input end of a blood filter through a pipeline. The output end of the blood filter is connected with a detector. The detector is connected with a blood component separator through a pipeline. The bottom end of the right side of the blood component separator is connected with a blood component collecting container through a pipeline. The blood component collecting container is connected with anair pump through a pipeline. By using the laser blood collector, the flow dividing pipe and a standing mechanism in cooperation, the safety during blood collecting is improved; through the mixing mechanism, an anticoagulant and blood can be more evenly mixed, blood coagulation is prevented, the blood collecting stability is improved, and the stability and safety of the system are greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pneumatic blood collection system. Background technique [0002] At present, the centrifugal and membrane filtration blood component collection equipment at home and abroad generally use peristalsis when collecting blood components. [0003] The peristaltic method of moving pumps collects and returns human blood. The manufacturing process of peristaltic pumps is complicated and the technical requirements are high. The application level of peristaltic pumps of various manufacturers is uneven. The key factor of life is difficult to control. When blood is collected by peristaltic pump peristalsis, it is easy to cause blood cell rupture caused by extrusion, hemolysis caused by high temperature, pipeline rupture caused by extrusion, blood pressure fluctuation of blood donors caused by peristalsis, and complicated operation. In view of the above shortcomings, the safety ...
