It is fixed, gentle, spilling for sample is not resulted in, is connected on the outer protection tube 2 with protective cap 4 after the first rubber stopper 3 is extracted；When need
When filling in the first rubber stopper 3, only 4 reverse flip of protective cap need to be pressed the sealing that protective cap 4 is capable of achieving blood taking tube.For
It is easy to protective cap 4 to promote, in the present embodiment, the opposite side of protective cap 4 is provided with the brim of a hat 42.The brim of a hat 42 can facilitate protective cap
4 stress.
Centre of the auxiliary sampling pipe 5 inside internal layer collection tube 1 and hanging setting, rubber neck 6 are located at auxiliary sampling
At the mouth of pipe of pipe 5, the medial surface of rubber neck 6 is fitted close with the outer wall of auxiliary sampling pipe 5, the lateral surface of rubber neck 6 with
The inwall of internal layer collection tube 1 is fitted close, and the tube wall of auxiliary sampling pipe 5 is provided with blood sample outlet 51, the mouth of pipe of auxiliary sampling pipe 5
Place is tightly connected with the second rubber stopper 7, and the second rubber stopper 7 is just to the second blind hole 321.When in use, bloodletting needle is from the first blind hole
311 pass through the second blind hole 321, are pierced into the second rubber stopper 7, inject blood sample to auxiliary sampling pipe 5, and blood sample covers blood sample outlet 51
Afterwards, internal layer collection tube 1 is flowed into, so, two pipe blood samples is obtained with by once blood drawing.Further, internal layer collection tube 1
Tube wall can be with coated agent, this way it is possible to realize once take blood just obtaining with reagent and the blood sample without reagent.
As internal layer collection tube 1 and the outer protection tube 2 are to be assembled under vacuum conditions, after assembling product, can be true
The gap formed by the inwall of the outer wall and the outer protection tube 2 of protecting internal layer collection tube 1 is vacuum environment, and the choke of product is blocked water
Optimal effect is played, due to rational in infrastructure, industrialized production is especially suitable for, is advantageously reduced production cost.
There is the first blind hole 311 and the second blind hole 321 respectively that cave inward due to filling in neck 31 and cock cap 32 so that medical care
Personnel can reduce penetration Resistance, so as to reduce puncturing the finger fatigue for bringing for a long time during rubber stopper 3 is punctured.
Refering to Fig. 2, it is the structural representation of second embodiment of the invention vacuum test tube.The vacuum test tube of the present embodiment
Vacuum test tube difference with first embodiment is that the mouth of pipe outer wall of the outer protection tube 2 is provided with boss with holes 21, protection
The side of cap 4 is connected by rotating with boss with holes 21.The protective cap 4 of the present embodiment can be overturn around boss with holes 21, after upset
Remain attached to (as shown in Figure 3) on boss with holes 21.
By the way, protective cap is set in together by vacuum test tube of the invention with rubber stopper, protective cap with it is outer
The mouth of pipe of layer protection pipe rotates connection, when needing to extract rubber stopper, need to only push up protective cap, and protective cap and rubber stopper are protecting
Helmet is rotated for fulcrum with the junction of the outer protection tube, and the rubber stopper for comparing existing blood taking tube does relative rectilinear fortune
It is dynamic, reduce needed for unlatching firmly such that it is able to facilitate rubber stopper to separate with the mouth of pipe.
Embodiments of the invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, it is every using this
