Abstract
The utility model discloses a safe blood transfusion filtrating device, which comprises a main bag and two auxiliary bags, wherein, the main bag is a blood sampling bag, and the blood sampling bag is connected with a blood sampling needle through a flexible pipe with a control valve, the two auxiliary bags are a red blood cell collecting bag and a blood plasma collecting bag, the red blood cell collecting bag and the blood plasma collecting bag are also connected with the blood sampling bag through the flexible pipe with the control valve, a cylinder-shaped filtering net is arranged at the end where the blood cell collecting bag and the blood plasma collecting bag are connected with the blood sampling bag. Because the extrusion filtering separation method with the filtering net is adopted, the filtering effect is good, the white blood cell rejection rate is high, the transfusion quality is ensured, and the structure is simple and the utilization is convenient.
Description
Technical field
This utility model relates to a kind of transfusion set that uses clinically, especially relates to a kind of blood transfusion filting device of removing blood middle leukocytes.
Background technology
Leukocyte in blood and the blood constituent can cause transfusion reaction of the same race, and this is that one is present in the blood of dedicating to because the leukocyte band in the blood antibacterial, the virus of engulfing in blood donor's body.Leukocyte leaves human body and just becomes short-lived cell, 3-5 days just loss of activity, and the antibacterial that it is engulfed, virus also exist.If give the weak patient of health with this without the blood infusion of handling, often can cause nonhemolytic febrific reaction.This prevents this situation, all will remove processing to the leukocyte in the blood before the blood transfusion clinically.At present, each big medical institutions all is extensive use of filter and removes leukocyte in whole blood and the blood constituent to reduce transfusion reaction.But mainly there are two problems in the leucocyte filter that uses at present: the one, and complex structure, the cost height has influenced and has promoted the use of; The 2nd, poor filtration effect, leukocyte removal efficiency is low.
Summary of the invention
The purpose of this utility model is exactly the above problem that exists in filtering at existing blood transfusion, and a kind of safe transfusion defecator is provided, have good filtration effect, improve the advantage of blood transfusion quality, and simple in structure, easy to use, cost is low.
The purpose of this utility model is to realize like this, this blood transfusion filting device comprises a main bag, two secondary bags, described main bag is blood taking bag, flexible pipe by a band control valve on the described blood taking bag links with this pin of blood sampling, described two secondary bags are erythrocyte collecting bag and plasma collection bag, described erythrocyte collecting bag and plasma collection bag also are to link by flexible pipe and the blood taking bag of being with control valve, and the end that described erythrocyte collecting bag and plasma collection bag and blood taking bag link is provided with columnar drainage screen.
During use, adopt the isolating way of press filtration, promptly with blood plasma-separating clip extruding blood taking bag, erythrocyte in the blood and blood plasma enter erythrocyte collecting bag and plasma collection bag through drainage screen, flexible pipe, and leukocyte promptly is left in the blood taking bag.
The beneficial effects of the utility model: owing to adopted the press filtration separation method of band drainage screen, good filtration effect, the leukocyte depletion rate height has guaranteed the blood transfusion quality, and simple in structure, easy to use.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a sketch map of the present utility model
Among the figure: 1, blood taking bag 2, erythrocyte collecting bag 3, plasma collection bag 4, flexible pipe 5, control valve 6, drainage screen 7, blood taking needle
The specific embodiment
As shown in Figure 1, this blood transfusion filting device comprises that the flexible pipe 4 by a band control valve 5 links with blood sampling 7 pins on a blood taking bag 1, erythrocyte collecting bag 2 and plasma collection bag 3 blood taking bags 1, erythrocyte collecting bag 2 and plasma collection bag 3 also are to link with blood taking bag 1 by the flexible pipe 4 of being with control valve 5, and erythrocyte collecting bag 2 and plasma collection bag 3 are provided with columnar drainage screen 6 with the end that blood taking bag 1 links.During use, adopt the isolating way of press filtration, promptly with blood plasma-separating clip extruding blood taking bag 1, erythrocyte in the blood and blood plasma enter erythrocyte collecting bag 2 and plasma collection bag 3 through drainage screen 6, flexible pipe 4, and leukocyte promptly is left in the blood taking bag 1.
