Abstract
The utility model discloses a blood constituent separating device which comprises a separation bag body. The separation bag body is in the shape of a long strip, has flexibility and is used for storing blood. A blood input opening is formed in one end of the separation bag body, a constituent leading-out route is arranged at the other end of the separation bag body, and the constituent leading-out route is used for leading out at least a part of constituents of blood from the separation bag body. The blood constituent separating device can separate blood constituents, and is simple in structure, low in manufacturing cost, and suitable for being produced in batch.
Description
Technical field
This utility model relates to medical instruments field, specifically a kind of blood constituent segregation apparatus.
Background technology
It is the main source of medicinal blood that human body is donated blood, difference needs blood person often only needs certain or several specific blood constituent, principle with " what lacks what is mended ", the a certain composition of infusion optionally, thereby greatly improved patient's treatment of blood transfusion effect, reduced the incidence rate of blood transfusion untoward reaction, reduced a large amount of blood wastes, the human body that simultaneously alleviates patient is subject to blood burden and financial burden.Therefore in the modern times, donate blood in technology, adopt the separated method gathering of blood constituent to gather respectively each composition of blood more.The separation of blood cell density gradient centrifugation has been widely used in blood separation field, and existing exocentric structure majority is rigidity cavity isolating construction, and consumptive material cost of manufacture is high, and difficulty is large.
Summary of the invention
In order to address the above problem, the invention provides a kind of blood constituent segregation apparatus, the mechanism that this device is flexible belt hemocyte separation.Mechanism structure of the present invention is simple, and cost of manufacture is low, is suitable for batch production.
The scheme of technical solution problem of the present invention is: blood constituent segregation apparatus, comprise separated bag, described separated bag is strip, have flexible, for stored blood; One end of separated bag is provided with blood input port, and one end is provided with composition and derives path, for derive at least a portion composition of blood from separated bag.
Described composition is derived path to be by housing and separated bag inwall and to be arranged on the layering dividing plate between housing and separated bag inwall, coordinate corresponding outlet tube to form, described composition is derived path has blood plasma to derive path, platelet and leukocyte derivation path, erythrocyte derivation path.
This utility model blood constituent segregation apparatus can be separated by blood constituent, and it is simple in structure, cost of manufacture is low, be suitable for batch production.
Accompanying drawing explanation
Fig. 1 is that this utility model blood constituent segregation apparatus uses schematic diagram;
Fig. 2 is the end partial structurtes schematic diagram of the separation bag of this utility model blood constituent segregation apparatus;
Fig. 3 is the profile of A-A in Fig. 2;
Fig. 4 is the profile of B-B in Fig. 2;
In figure, 1 blood input port, 2 rotating separation mechanisms, 3 separating plasma layers, 4 platelet and leukocyte stratum disjunctum, 5 erythrocyte stratum disjunctums, 6 separated bags, 7 housings, 8 layering dividing plates, 9 housing back cavities, 10 blood plasma outlet tubes, 11 platelet and leukocyte outlet tube, 12 separating plasma mouths, 13 erythrocyte separating openings, 14 erythrocyte outlet tubes, 15 erythrocyte delivery outlets.
The specific embodiment
As shown in Figure 1, blood constituent segregation apparatus of the present utility model, comprises separated bag 6, and described separated bag is strip, have flexible, for stored blood; One end of separated bag 6 is provided with blood input port 1, one end is provided with composition and derives path, for derive at least a portion composition of blood from separation bag, composition is derived path and can be connected with storage capsule or composition lead-in path, and composition lead-in path is for importing at least a portion composition the blood of deriving from described separation bag.Blood enters separated bag 6 through blood input port 1, separated bag 6 is placed in rotating separation mechanism 2, and described rotating separation mechanism 2 is applicable to the fixing centrifuge of separated bag etc.Separated bag 6, along with rotating separation mechanism 2 is rotated, according to density gradient centrifugation separation principle, is isolated separating plasma layer 4, platelet and leukocyte stratum disjunctum 5, erythrocyte stratum disjunctum 6.
Composition of the present utility model is derived the structure in path can be with reference to figure 2-Fig. 4, described composition is derived path to be by the inwall of housing 7 and separated bag 6 and to be arranged on the layering dividing plate 8 between housing 7 and separated bag inwall, coordinates corresponding outlet tube formation.Blood after layering, erythrocyte stratum disjunctum 5 enters housing back cavity 9 by erythrocyte separating opening 13; Platelet and leukocyte stratum disjunctum 4 directly enter platelet by layering dividing plate 8 and further processing is done in 11 outputs of leukocyte outlet tube; Separating plasma layer 3 enters housing back cavity 9 by separating plasma mouth 12; The erythrocyte that enters housing back cavity 9 is further separated with blood plasma, and according to isodensity gradient separations principle, the output mouth of pipe that enters differing heights is exported respectively.As shown in Figure 3, because blood plasma density is less than erythrocyte, on centrifugal device, the blood plasma after centrifugal at internal layer, erythrocyte at skin, therefore separating plasma mouth 12 position radiuses are less than in the position of erythrocyte separating opening 13 radius.Separating plasma mouth 12 is corresponding with blood plasma outlet tube 10; Erythrocyte separating opening 13 is corresponding with erythrocyte outlet tube 14 and erythrocyte delivery outlet 15.
