Description
Technical field
The present invention relates to medical instruments field, particularly relate to blood-taking device.
Background technology
At present, clinical with blood plasma for specimen carry out index of correlation detection time, the gatherer process for blood plasma is such that leading to
Cross blood taking needle by blood suction anticoagulant/separation gel test tube, centrifugal after, it is thus achieved that blood plasma.This method suffers from the drawback that (1)
When specimen amount is more, owing to each specimen is required to be centrifuged, TAT(assay report time certainly will be caused) extend, impact inspection
Test accuracy and the clinic diagnosis of result.(2) owing to hemocyte not being separated in time with blood plasma, former because of hemocyte own metabolism etc.
Cause, if the detection waiting time is long, can cause the Indexs measure results such as blood glucose error occur.
Summary of the invention
The defect existed for prior art, the invention provides a kind of negative pressure leaching formula blood plasma being applicable to medical experiment
Harvester, can quickly and easily complete the collection of whole blood and blood plasma.
Concrete technical scheme is: a kind of negative pressure leaching formula sampled plasma device being applicable to medical experiment, divides including blood
Orchestration, blood taking needle, separation pipe, the first plug puncture needle and the second plug puncture needle, blood allotter is the housing of inner hollow
Structure, blood allotter upper end offers blood inlet, and blood taking needle is connected with blood inlet by flexible hose, blood allotter lower end
Offering the first blood outlet and the second blood outlet, the first plug puncture needle is connected by flexible hose and the first blood outlet；Separate
Pipe and blood allotter lower end are connected and separate pipe and connected with blood allotter by the second blood outlet, and the second plug puncture needle is logical
Cross flexible hose and separate the connection of pipe lower ending opening, separate and be provided with plasmapheresis net between pipe lower ending opening and the second blood outlet.
Described flexible hose is plastic flexible pipe.
Described blood allotter and separation pipe are made by transparent material.
Present configuration is simple, and low cost of manufacture is easy to use, has the strongest promotional value.
Make just to directly obtain plasma specimen when blood sampling by plasmapheresis net, be greatly shortened blood plasma preparation time, with
Time blood plasma directly separate with hemocyte after leaving blood vessel, metabolic effect can be down to minimum, effectively reduce hemocyte metabolism shadow
Ring；Whole blood sample and plasma specimen can be obtained respectively by the first plug puncture needle and the second plug puncture needle.
Accompanying drawing explanation
Fig. 1 is inventive structure schematic diagram.
Detailed description of the invention
As it is shown in figure 1, a kind of negative pressure leaching formula sampled plasma device being applicable to medical experiment, including blood allotter 1,
Blood taking needle 2, separation pipe the 3, first plug puncture needle 4 and the second plug puncture needle 5, blood allotter 1 is the housing of inner hollow
Structure, blood allotter 1 upper end offers blood inlet, and blood taking needle 2 is connected with blood inlet by flexible hose, blood allotter 1
Lower end offers the first blood outlet 6 and the second blood outlet 7, and the first plug puncture needle 4 is connected by flexible hose and the first blood outlet 6
Connect；Separate pipe 3 and blood allotter 1 lower end to connect and separate pipe 3 and connected with blood allotter 1 by the second blood outlet 7, second
Plug puncture needle 5 is connected with separating pipe 3 lower ending opening by flexible hose, separates between pipe 3 lower ending opening and the second blood outlet 7
It is provided with plasmapheresis net 8.
Flexible hose is plastic flexible pipe, and blood allotter 1 and separation pipe 3 are made by transparent material, it is simple to observe blood sampling
Situation.
In use, first blood taking needle 2 is inserted Ink vessel transfusing, if needing to gather whole blood sample, by the first plug puncture needle 4
In insertion negative pressure blood-taking tube, in negative pressure blood-taking tube under the effect of negative pressure, now blood passes sequentially through blood taking needle 2, blood distribution
Device 1 and the first plug puncture needle 4 enter in negative pressure blood-taking tube, now collect in negative pressure blood-taking tube for whole blood sample；If
When needing to gather plasma specimen, the second plug puncture needle 5 is inserted in the negative pressure blood-taking tube being added with anticoagulant, at negative pressure hemostix
In pipe under the effect of negative pressure, now blood passes sequentially through blood taking needle 2, blood allotter 1 and separates pipe 3, and blood is through separating
Through plasmapheresis net 8 during pipe 3, hemocyte is stayed in separation pipe 3 by plasmapheresis net 8, separates through plasmapheresis net 8
Blood plasma enter in negative pressure blood-taking tube by the second plug puncture needle 5, now collect in negative pressure blood-taking tube for plasma specimen,
Anticoagulant in negative pressure blood-taking tube can prevent the clotting of plasma.
Blood taking needle 2, plasmapheresis net the 8, first plug puncture needle 4 and the second plug puncture needle 5 are prior art.
