Embodiment Construction

[0021] refer to figure 1 , the blood separation device comprises: a plunger pump device, a stepping motor 2 and a controller 1 for driving the plunger pump device, a separation box, an original blood bag 12, a vacuum bag 14 communicated with the infusion outlet of the separation box, and a waste liquid of the separation box The waste liquid bag 15 connected to the outlet, the inlet and outlet of the plunger pump device, the infusion inlet of the separation box, and the original blood bag are connected to each other through the pipeline and the three-way joint 13. The original blood bag 12 is placed at a high place to facilitate the flow of blood by its own weight.

[0022] The separation box includes a receiving plate 18, a filter plate 17 and a cover plate 16 that are sealed and stacked together in sequence. An infusion tank is provided on the lower surface of the cover plate 16, and through holes are respectively provided at both ends of the infusion tank to lead out the cove...

Abstract

The invention relates to a blood separation device and a separation method, in particular to a blood separation device and a separation method used for filtrating leucocyte. The blood separation device comprises a piston pump device, a stepping motor and a control used for driving the piston pump device, a separation box, a raw blood bag, a vacuum bag communicated with the liquid conveying outlet of the separation box, and a waste liquid bag which is communicated with the waste liquid outlet of the separation box; the blood separation device and the separation method are characterized in that the inlet and outlet of the piston pump device, the liquid conveying inlet of the separation box and the raw blood bag are communicated with each other by a three-way pipe; the raw blood bag is arranged at high attitude so as to carry out the blood separation; the stepping motor is controlled, the piston rod of the piston pump reciprocates, the blood flows, and the filtrated blood is collected at the same time.

Description

technical field [0001] The invention relates to a blood separation device and a separation method, in particular to a blood separation device and a separation method for filtering white blood cells. Background technique [0002] At present, the blood separation methods that filter out white blood cells mainly include: one is the filter membrane blood separation method, that is, the blood is passed through the filter membrane, and the purpose of blood separation is achieved by utilizing the difference in the size of the blood cells and the pore size of the micropores on the filter membrane. The filter membrane material adopts inorganic polymer such as multi-layer polyester fiber non-woven fabric, high-grade glass fiber and so on. This method is applied to make a filter membrane separation device with a porous membrane filter material as the main body. However, when the filter membrane blood separation method is used, since the filter membrane is made by non-mechanical proces...
