Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing
Illustrate specific embodiment of the utility model.
As depicted in figs. 1 and 2, a kind of single blood sampling sampler that the utility model embodiment provides, including three-way ball
First 2, the first interface of the threeway bulb 2 is connected with blood taking needle 1, and the second interface relative with first interface, which is connected with, takes blood vessel 3,
The end of blood vessel 3 is taken to be connected with disposable storage blood test tube.3rd interface of three-way connection 2 is connected with probe tube 4, on probe tube 4
Provided with the first control valve 7.Sampled for convenience of blood sampling, taking blood vessel 3, probe tube 4 is interior for the internal negative pressure taking blood vessel for being provided with negative pressure
Portion is provided with the sampling below atmospheric pressure pipe of negative pressure, punctures into after vein in blood taking needle 1, in the case where taking the suction function inside blood vessel 3 and takes
Under suction function inside sample pipe 4, venous blood is by blood taking needle 1 respectively automatically into taking blood vessel 3 and probe tube 4.Probe tube 4
End be provided with access first 5, take blood vessel 3 body be provided with and access it is first 5 insert scarves close slotting embedding seats 6, insert embedding seat 6 in provided with
The return flow line 64 for taking blood vessel 3 to connect, return flow line 64 is provided with the second control valve 8.Puncture blood collecting sampling is being carried out to vein
When, first first 5 insertion of access on probe tube 4 is inserted in embedding seat 6, opens the first control valve 7 and the second control valve 8 so that sampling
