Specific embodiment
Specific embodiment of the present utility model is described in detail with reference to the accompanying drawing.
In the embodiments of the present invention, as shown in Fig. 1~2, a kind of a homemade device for collecting blood gas specimens is provided, the blood sample collection
Device includes blood sample collector 1, triple valve 2, blood taking needle 3 and puncture needle 4.Blood sample collector 1 during this is practical can be blood drawing
Pump, can also be with syringe etc., first by the pump blood in vein into blood sample collector 1, further according to pushing away for blood sample collector 1
Function is sent to push to blood in specimen bottle.
Syringe needle is caused to pollute using same syringe needle to avoid taking a blood sample and puncture, this practical middle blood sampling and puncture are with different
Syringe needle carries out, that is, has special blood taking needle 3 and puncture needle 4.This it is practical in blood taking needle 3 and puncture needle 4 by triple valve 2 with
Blood sample collector 1 is connected, and triple valve 2 is in T shape comprising input interface 21, the first output interface 23 and the second output connect
Mouth 22, wherein input interface 21 and the first output interface 23 are located at vertical direction, and the second output interface 22 is located at horizontal direction,
And triple valve 2 is internally provided with the gate valve that control blood flows to blood sample collector 1 or puncture needle 4, and outside is provided with and gate valve
The turning handle 24 being fixedly connected, gate valve can be adjusted in rotation turning handle 24, and then controls the flow direction of blood.Triple valve 2
In input interface 21 connect with blood taking needle 3, the first output interface 23 is connected with blood sample collector 1, the second output interface 22
It is connected with puncture needle 4.Puncture needle 4 is easy to damage medical worker in use, to avoid this problem, this reality
The syringe needle 41 of puncture needle 4 in is wrapped up with protective case, and only when puncturing, 41 ability of syringe needle in puncture needle 4 is from protection
It stretches out and is punctured in set, after the completion of puncture, syringe needle 41 is retracted into protective case, be can effectively avoid puncture needle and is made to medical worker
At injury.41 lower end of syringe needle in puncture needle 4 is provided with connector 44, and 44 end of connector is connected with drainage tube 5, drainage tube 5
The other end is connect with the second output interface 22, i.e., puncture needle 4 is connect by drainage tube 5 with the second output interface 22, and drainage tube 5 is
PE pipe, emulsion tube or silicone tube etc.；Protective case in puncture needle 4 includes cylindrical sleeve 42 and is connected to cylindrical sleeve 42
The elastic component 43 of lower end, this it is practical in cylindrical sleeve 42 be plastic tube, diameter is gradually increased from top to bottom, i.e., cylindric
Sleeve 42 is tapered, and elastic component 43 is spring ring or rubber ring etc., and 43 one end of elastic component is fixedly connected on cylindrical sleeve 42
Lower end, the other end are fixedly connected with connector 44；To guarantee syringe needle 41 is adequately covered, when 43 free extension of elastic component length
It should be greater than the length of syringe needle 41 with the sum of the length of cylindrical sleeve 42, and to realize puncture function, then when elastic component 43 compresses
Length and the sum of the length of cylindrical sleeve 42 should be less than the length of syringe needle 41, the length of this practical middle syringe needle 41 is 2~
3cm, the length of elastic component 43 are 0.5cm, and the length of cylindrical sleeve 42 is 2~3cm.
Due to this it is practical in puncture needle 4 be attached by drainage tube 5, when not puncturing, one can be caused to blood sampling operation
Fixed influence, therefore, originally practical that clip 11 is provided on the lateral wall of blood sample collector 1, clip 11 is arc-shaped, with blood
