Abstract
The utility model discloses a plasm separator used for plasm collection. The utility model is composed of a whole blood inflow passage, a blood separating rotor, a plasma outflow passage and an accessory. The utility model matches with a peristaltic pump and a centrifuge. Under a totally closed condition, the utility model completes blood sampling, plasma division of centrifugation, and blood cell feedback processes continuously, completely avoids the cross infection between blood donors, feedback error and plasm pollution, and enhances efficiency, which is used for the collection of feedstock plasm and clinical plasm.
Description
This utility model relates to the device of blood separation blood plasma.
With the immediate prior art of this utility model be that public artificial blood plasma list is adopted art, its method is that manual method extracts whole blood, doing anticoagulant in storage blood bag or storage blood bottle handles, place in the centrifuge blood bag or blood bottle centrifugal then, hemocyte and separating plasma, then plasma layer is introduced in other container, at last hemocyte also is defeated by the blood donor, this technology is mainly used in the collection of raw blood plasma and blood used in clinic slurry.
The problem that prior art exists is: 1, take a blood sample, divide slurry, also fail and must three step of branch manual methods carry out poor continuity separately.2, cross infection easily takes place between the blood donor.3, also defeated process is prone to wrong defeated phenomenon.4, institute's blood collecting vulnerable to pollution causes waste.5, complex operation, labor intensity is big.
The purpose of this utility model is to propose a kind of plasma separating unit, to reach blood sampling, divide slurry, also to fail under totally enclosed condition and carry out continuously synchronously, to improve the quality of blood plasma, guarantees blood donor's safety, improves work efficiency, makes full use of blood resource.
For achieving the above object, the solution that this utility model is taked is: blood sampling and centrifugal branch slurry is carried out synchronously, the plasma collection that separation is obtained is in a container, hemocyte is put aside in separator, when hemocyte is put aside some, promptly also be defeated by the blood donor by former blood sampling pipeline, it is complete also to be totally lost, and enters next circulation blood sampling again, divides slurry, also fails.Until adopting predetermined plasma volume.Design one and have the whole blood admission passage, centrifugal rotary body, the plasma separator that blood plasma flow pass and adnexa four parts constitute.Wherein the whole blood admission passage is made up of whole blood inlet and whole blood conduit, centrifugal rotary body is by wearing piece, ring for fixing, separating tube, rotating cylinder are formed, the blood plasma flow pass flows out the gap by blood plasma and the blood plasma outlet is formed, adnexa is made up of guard shield, pad, stator, glue bowl, on rotating cylinder, designed arcuate ridges, arc rib and cup-shaped bottom structure.
When whole blood from whole blood inlet when the whole blood conduit flows to the cup-shaped end of rotary body, under the rotating centrifugal effect of rotary body, utilize the difference of proportion, hemocyte is slided into the portion of the expanding savings of rotary body along the rotation body wall by the cup-shaped end, wherein the arc rib is convenient to moving of concentrating cells, the iris action of arcuate ridges makes blood plasma fully separate with hemocyte.Along with whole blood constantly enters rotary body, content constantly increases, and the blood plasma that is positioned at the rotary body centre position then overflows along the blood plasma outlet, flows into collection container.When hemocyte is put aside when a certain amount of in the rotary body portion of expanding, the whole blood time-out enters branch slurry device, the deshydremia cell is after adding an amount of diluent, under the peristaltic pump effect, along the also defeated blood donor of the opposite course of whole blood flow channel, it is complete also to be totally lost, first circulation is promptly accused and is finished, enter next circulation again, repeat above program, until collecting predetermined plasma volume.
Because in the above-mentioned solution, design whole blood and entered with the blood plasma overflow process and carry out synchronously, made blood sampling and divide slurry to be carried out continuously, can repeat several circulations of taking turns as required, take a blood sample, divide and starch, also fail to link up and finish, avoided cross infection and the generation that feeds back mistake between the blood donor.Totally enclosed structure has fully been avoided pollution.Owing to greatly simplified operation sequence, can increase work efficiency effectively and reduce labor intensity.
Below in conjunction with drawings and Examples this utility model is described in detail.
Fig. 1 is the structural representation of plasma separator profilograph and first embodiment.
In separator profilograph shown in Figure 1, flow out gap 12, separating tube 13, whole blood conduit 14, whole blood catheter opening 15, the cup-shaped end 16, constitute plasma separator by blood plasma outlet 1, guard shield 2, pad 3, ring for fixing 4, rotating cylinder 5, arcuate ridges 6, arc rib 7, whole blood inlet 8, stator 9, glue bowl 10, wearing piece 11, blood plasma.
Its operation principle is: plasma separator and centrifuge and peristaltic pump are supporting, and pad 3 is fixed with top, and rotary body rotates relative to pad 3, and keep sealing.Whole blood inlet 8 links to each other with the anticoagulant pipe with blood taking tube, and blood plasma exports 1 and links to each other with plasma bags.Whole blood flows to the cup-shaped end 16 of rotating cylinder 5 along whole blood conduit 14 from whole blood catheter opening 15 through whole blood inlet 8, rotating cylinder 5 is in the high speed rotating state, hemocyte and plasma fraction are because of difference of specific gravity in the whole blood, the centrifugal force difference that produces, heavy hemocyte is just pasting the rotation body wall, at the isolating hemocyte in the cup-shaped ends 16 along arc rib 7, move up, be obstructed to arcuate ridges 6, cell is able to fully separate with blood plasma, the little blood plasma of proportion then phase pair cell is positioned at the middle part, and the blood constituent in rotating cylinder increases gradually, and the blood plasma that is arranged in the center promptly flows into blood plasma container along the blood plasma passage from blood plasma outlet 1.When deshydremia cell in the rotating cylinder is increased to when a certain amount of, suspend and divide slurry, deshydremia cell in rotating cylinder 5 adds diluent, by the effect of peristaltic pump, the rightabout that enters along whole blood feeds back to the blood donor, and feedback finishes, again carry out next circulation and divide slurry, until collecting predetermined plasma volume, at last the hemocyte in the rotating cylinder 5 is fed back, promptly finish and gather one fen slurry one feedback overall process.
