Abstract
The utility model discloses a kind of blood constituent filtering exhaust device and its blood storage bag.Described device includes puncture needle (5), filter (4), liquid stopping clamp (2) and blood storage bag (1), blood to be filtered filters through puncture needle inflow filter, blood storage bag is stored into again, liquid stopping clamp is used for temporary transient at any time or terminates filter, each several part is connected by flexible pipe, and the blood storage bag has resistance bacterium air cleaner (3).Blood constituent filtering exhaust device of the present utility model conveniently excludes the air remained in blood storage bag when adopting transfusion filtration such as leucocyte prepares blood constituent, ensure that smoothly circulation and postorder prepare other blood constituents to blood constituent, using with it is easy to operate, practicality is stronger.
Description
Technical field
The utility model belongs to medicine instrument field, and in particular to a kind of blood storage bag and tool with resistance bacterium air cleaner
There is the blood constituent filtering exhaust device of the blood storage bag.
Background technology
Adopting blood transfusion field at present, unwanted blood constituent such as leucocyte removed by filtering off, especially for whole blood,
Red cell suspension and blood platelet, collect deposit or application that filtered solution realizes blood constituent.Pass through leukoreduction filter in blood
Device is to during blood storage bag, and the air of residual can flow into and be full of in receipts with blood in original pipeline, filter and blood storage bag
In the blood storage bag for collecting blood constituent.Operation is exhausted by the flexible pipe of filtration system in existing method.For example, have when in blood storage bag
During air swollen bag, manual compression blood storage bag, air inherent filtration system is returned in blood vessel to be filtered.So operation has two
Individual problem, first, filtration system route is grown, air discharge is more hard, and be not easy to be completely exhausted out air, another is filtering
The blood constituent remained in afterwards in filtration system can flow backwards, and larger damage to red blood cell be present, influence the preservation of blood constituent
Effect.In consideration of it, need to develop a kind of safely and effectively exhaust apparatus can facilitate blood station or hospital prepare in blood constituent and
Bleeding is easily realized using process, improves efficiency, while also can guarantee that the preservation quality of blood constituent.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of blood constituent filtering exhaust device,
The device exhaust and convenient, the blood constituent after filtering is avoided to flow backwards.
Above-mentioned technical purpose of the present utility model is achieved through the following technical solutions：
A kind of blood constituent filtering exhaust device, described device include puncture needle (5), filter (4) and blood storage bag (1),
Each several part is connected by flexible pipe, and the blood storage bag is communicated with resistance bacterium air cleaner (3).
Puncture needle (5) and filter (4) form a simple filtration system, for filtering off unwanted blood constituent,
Such as leucocyte.Blood to be filtered is contained in the container as shown in the A of accompanying drawing 2, and passes through filter (4) through puncture needle (5)
Filtering, is finally collected in blood storage bag (1).When there is air in blood storage bag, slight squeeze blood storage bag, air can be through blood storage bag
Hinder bacterium air cleaner (3) discharge.
As preferable technical scheme, blood constituent filtering exhaust device of the present utility model also includes liquid stopping clamp (2),
Liquid stopping clamp is used to suspend or terminate filter, any position between puncture needle and blood storage bag.
As preferable technical scheme, blood constituent filtering exhaust device of the present utility model, the resistance bacterium air of blood storage bag
The terminal of filter (3) has sheath (6), and sheath is used to protect and completely cut off extraneous contamination.
As preferable technical scheme, blood constituent filtering exhaust device of the present utility model can be by a blood storage bag
It is formed by connecting with the filtration system being made up of puncture needle (5), filter (4) for being not limited to one, the filtration system may be selected
Property includes liquid stopping clamp (2).A plurality of filtration system is connected by threeway with blood storage bag (1), or directly with blood storage bag (1) phase
Even.
The utility model additionally provides a kind of blood storage bag, including bag body (7), connected entrance (8), and connected by flexible pipe
Hinder bacterium air cleaner (3).The blood storage bag can be applied to foregoing blood filtration exhaust apparatus or application similar in terms of other.
As preferable technical scheme, the terminal of the resistance bacterium air cleaner (3) of the blood storage bag has sheath (6), uses
In protection and isolation extraneous contamination.
Brief description of the drawings
Fig. 1 is the blood constituent filtering exhaust installation drawing of embodiment 1.
Fig. 2 is the blood constituent filtering exhaust device application drawing of embodiment 1.
1 is blood storage bag, and 2 be liquid stopping clamp, and 3 be resistance bacterium air cleaner, and 4 be filter, and 5 be puncture needle, and 6 be sheath, and 7 are
The bag body of blood storage bag, 8 be the connected entrance of blood storage bag.
Embodiment
Below by way of embodiment, the above of the present utility model is described in further detail.But should not
This is interpreted as the scope of the utility model and is only limitted to following example by this.
Embodiment 1
A kind of blood constituent filtering exhaust device, as shown in Figure 1 and Figure 2, including puncture needle (5), filter (4), liquid stopping clamp
(2) and blood storage bag (1), each several part is connected by flexible pipe, and blood storage bag (1) is communicated with resistance bacterium air cleaner (3), hinders bacterium air mistake
The end of filter (3) has sheath (6).Blood to be filtered is contained in container A, through puncture needle, filter (such as leukoreduction filter
Device) filtering, into the blood storage bag (1) of collection, each several part is connected by flexible pipe, and blood storage bag is connected through connected entrance (8) with flexible pipe,
Communicated through hindering bacterium air cleaner (3) with outside air, when blood storage bag has air, extrude bag body (7), air is empty from bacterium is hindered
Air filter (3) is discharged, and the blood constituent remained in filtration system will not be caused to blow back into container A, simple to operate.
