Description
Technical field
This utility model is related to medical instruments field, more particularly to blood-taking device.
Background technology
At present, it is clinical when carrying out index of correlation with blood plasma as specimen and detecting, for the gatherer process of blood plasma is such：It is logical
Blood taking needle is crossed by blood suction anticoagulant/separation gel test tube, after centrifugation, blood plasma is obtained.There is following drawback in this method：（1）
When specimen amount is more, because each specimen is required to centrifugation, TAT certainly will be caused（Assay report time）Extend, affect inspection
Test the accuracy and clinic diagnosis of result.（2）Due in time not separating hemocyte with blood plasma, because of originals such as hemocyte own metabolisms
Cause, if the detection waiting time is long, can cause the Indexs measure result such as blood glucose error occur.
Utility model content
For the defect that prior art is present, this utility model provides a kind of negative pressure leaching formula suitable for medical experiment
Sampled plasma device, the quick and easy collection for completing whole blood and blood plasma of energy.
Concrete technical scheme is：A kind of negative pressure leaching formula sampled plasma device suitable for medical experiment, including blood point
Orchestration, blood taking needle, separating 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 by flexible hose with blood inlet, blood allotter lower end
The first blood outlet and the second blood outlet are offered, the first plug puncture needle is connected by flexible hose with the first blood outlet；Separate
Pipe is connected with blood allotter lower end and separating pipe is connected by the second blood outlet with blood allotter, and the second plug puncture needle leads to
Cross flexible hose to be connected with separating pipe lower ending opening, plasmapheresis net is provided between separating pipe lower ending opening and the second blood outlet.
The flexible hose is plastic flexible pipe.
The blood allotter and separating pipe are made by transparent material.
This utility model simple structure, low cost of manufacture is easy to use, with very strong promotional value.
Make just directly obtain plasma specimen in blood sampling by plasmapheresis net, greatly shorten blood plasma preparation time, together
When blood plasma directly separate with hemocyte after blood vessel is left, metabolic effect can be minimized, effectively reduce hemocyte metabolism shadow
Ring；Whole blood sample and plasma specimen can respectively be obtained by the first plug puncture needle and the second plug puncture needle.
Description of the drawings
Fig. 1 is this utility model structural representation.
Specific embodiment
As shown in figure 1, a kind of negative pressure leaching formula sampled plasma device suitable for medical experiment, including blood allotter 1,
Blood taking needle 2, separating pipe 3, the first plug puncture needle 4 and the second plug puncture needle 5, blood allotter 1 is the housing of inner hollow
Structure, the upper end of blood allotter 1 offers blood inlet, and blood taking needle 2 is connected by flexible hose with blood inlet, 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 with the first blood outlet 6
Connect；Separating pipe 3 is connected with the lower end of blood allotter 1 and separating pipe 3 is connected by the second blood outlet 7 with blood allotter 1, and second
Plug puncture needle 5 is connected by flexible hose with the lower ending opening of separating pipe 3, between the lower ending opening of separating pipe 3 and the second blood outlet 7
It is provided with plasmapheresis net 8.
Flexible hose is plastic flexible pipe, and blood allotter 1 and separating pipe 3 are made by transparent material, is easy to observation blood sampling
Situation.
When in use, first blood taking needle 2 inserted into Ink vessel transfusing, if necessary to collection whole blood sample, by the first plug puncture needle 4
In insertion negative pressure blood-taking tube, in the presence of negative pressure in negative pressure blood-taking tube, now blood passes sequentially through the distribution of blood taking needle 2, blood
The plug puncture needle 4 of device 1 and first is entered 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 insertion of the second plug puncture needle 5 is added with the negative pressure blood-taking tube of anticoagulant, in negative pressure hemostix
In pipe in the presence of negative pressure, now blood passes sequentially through blood taking needle 2, blood allotter 1 and separating pipe 3, and blood is through separation
Through plasmapheresis net 8 during pipe 3, plasmapheresis net 8 stays in hemocyte in separating pipe 3, separates through plasmapheresis net 8
Blood plasma entered 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 8, the first plug puncture needle 4 and the second plug puncture needle 5 are prior art.
