Abstract
The utility model relates to a disposable white blood cell removing blood bag, which comprises a closed blood taking needle and an anticoagulation complete blood bag. The lower part of the anticoagulation complete blood bag is connected with a guide tube through an easy-folding plunger. The guide tube is orderly connected in series with a filtering dripping funnel, a flow regulator, a white blood cell filter and an anticoagulation blood bag for filter. The white blood cell filter is connected in parallel with a guide tube with a switch clamp through a three-way. The anticoagulation blood bag for filter can be a single connection or a multiple connection structure. Since the utility model adds a set of white blood cell filter in a traditional plastic blood bag, the white blood cell flowing out of the body of a blood donor can be filtered out, and thus the quality of blood is raised. The disposable white blood cell removing blood bag has reasonable construction and convenient operation, being suitable for blood sampling and blood transfusion.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of disposable use leukocyte depleted blood bag.
Background technology
We know that disposable use blood bag is blood sampling and blood transfusion process medical apparatus and instruments commonly used, and it generally comprises closed blood taking needle, anticoagulated whole blood bag.The anticoagulated whole blood bag can be a simply connected, also can be multi-joint.Connect blood exchange transfusion set's operation of can transfusing blood during blood transfusion.Disposable use blood bag can play the closed blood sampling of disposable use, blood transfusion effect, can prevent and avoid clinical cross infection.We know that also human body blood contains leukocyte, and this leukocyte produces adverse influence to the donee sometimes, cause transfusion reaction in various degree.In addition, during storage, leukocyte also has adverse effect to blood constituent.So blood sampling, blood transfusion process are carried out leukoreduction filter and are very important.And present disposable use plastic blood bag does not all also have leucocyte filtration device, can not carry out leukoreduction filter.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, and operation, easy to use can be carried out the disposable use leukocyte depleted blood bag of leukoreduction filter to the blood of gathering.
The technical scheme in the invention for solving the above technical problem is: a kind of disposable use leukocyte depleted blood bag, comprise closed blood taking needle, anticoagulated whole blood bag, it is characterized in that: anticoagulated whole blood bag bottom is connected with conduit by easy folding plug, is connected with successively on the conduit to filter anticoagulation bag after dropping funnel, flow regulator, leucocyte filter, the filter.
This utility model leucocyte filter can also be by the conduit of a threeway belt switch clamp in parallel.Filter back anticoagulation bag can be simply connected, duplex, three or tetrad.
This utility model is owing to set up a cover leucocyte filtration device in the plastic blood bag that traditional sealing is used, the blood after the filtration is contained in the anticoagulation bag of filter back.Against existing technologies, its leukocyte in can filtering blood, and realize the hemofiltration Flow-rate adjustment.This utility model can fall the leukoreduction filter the effusive blood in blood donor's body, thereby has improved the quality of blood.Its structure rationally, and is easy for operation, is applicable to disposable blood sampling, blood transfusion use.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a kind of multi-joint structural representation of the present utility model
1. closed blood taking needles among the figure, 2. anticoagulated whole blood bag, 3. easy folding plug, 4. conduit 5. filters dropping funnel, 6. flow regulator, 7. leucocyte filter, 8. threeway, 9. switch clamp, 10. threeway, 11. conduits, 12. filter back anticoagulation bags.
The specific embodiment
As can be seen from Figure 1, a kind of disposable use leukocyte depleted blood bag of this utility model comprises closed blood taking needle 1, anticoagulated whole blood bag 2.Use when closed blood taking needle 1 is used for taking a blood sample, the helmet on it of fractureing just can carry out the puncture blood collecting of routine.Anticoagulated whole blood bag 2 is used for collecting whole blood.Their concrete structure and effect and prior art are basic identical, do not describe in detail.
Characteristics of the present utility model are: anticoagulated whole blood bag 2 bottoms are connected with conduit 4 by easy folding plug 3, are connected with successively on the conduit 4 to filter dropping funnel 5, flow regulator 6, leucocyte filter 7, filter back anticoagulation bag 12.Filter dropping funnel 5 and be used for grumeleuse and impurity in the filtering blood.Flow regulator 6 is used for regulating, the flow of controlled filter blood.Leucocyte filter 7 is used for the leukocyte in the filtering blood specially, and it comprises upper and lower casing and middle leukoreduction filter film.Filter back anticoagulation bag 12 is used for collecting filter back blood, and uses when being used for match, blood transfusion.，
This utility model is for the convenience of totally closed operation, and leucocyte filter 7 can also be by the conduit 11 of threeway 8 and threeway 10 belt switch clamps 9 in parallel.When the leukocyte in the filtering blood is operated, close switch clamp 9, the easy folding plug 3 on the anticoagulated whole blood bag 2 that fractures, blood enters in the filter back anticoagulation bag 12 through filtration dropping funnel 5, flow regulator 6, leucocyte filter 7.Open switch clamp 9 after filtration finishes, get rid of the gas in the filter back anticoagulation bag 12, close switch clamp 9 again.The conduit of heat seal sealing threeway 10 bottoms, filter back anticoagulation bag 12 uses for match, blood transfusion.
This utility model filter back anticoagulation bag 12 can multi-joint structure, carries out back anticoagulation deposit of multi-joint filter and use.As shown in Figure 2.Filter back anticoagulation bag 12 can be simply connected, duplex, three or the tetrad structure.The composition of multi-linked blood bag, structure and annexation and wherein the blood constituent lock out operation is identical with conventional multi-linked blood bag.
This utility model can fall the leukoreduction filter the effusive blood in blood donor's body owing to set up a cover leucocyte filtration device in traditional plastic blood bag, thereby has improved the quality of blood.Its structure rationally, and is easy for operation, is applicable to disposable blood sampling, blood transfusion use.
