Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that described embodiment is only the part of the embodiment rather than whole of the utility model
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
It is the structure diagram of the medical vacuum blood collection tube of the utility model first embodiment refering to Fig. 1.The utility model
The medical vacuum blood collection tube of embodiment includes internal layer collection tube 1, the outer protection tube 2, rubber stopper 3 and protective cap 4.
Internal layer collection tube 1 is inserted in the outer protection tube 2, and the tube wall of internal layer collection tube 1 is in wave structure, internal layer collection tube
Vacuum gap 11 is formed between 1 outer wall and the inner wall of the outer protection tube 2, and the nozzle outer diameter of internal layer collection tube 1 is slightly larger than outer
The internal diameter of layer protection pipe 2, so that the nozzle outer wall of internal layer collection tube 1 and the inner wall of the outer protection tube 2 closely press.Internal layer is adopted
Collector 1 is to be pressed under vacuum conditions in the outer protection tube 2, it is thus possible in outer wall and the outer protection tube 2 of internal layer collection tube 1
Inner wall between form vacuum gap.Internal layer collection tube 1 is, for example, that glass is made, and the outer protection tube 2 is, for example, that plastics are made, interior
The nozzle outer diameter of layer collection tube 1 is preferably greater than 0.1mm than the internal diameter of the outer protection tube 2.
The plug neck 31 and the cock cap 32 arranged on 31 top of plug neck that rubber stopper 3 includes lower part, plug neck 31 and internal layer collection tube 1
Nozzle is fitted close, and cock cap 32 is fitted close with the outer protection tube 2 and at least partly stretches out outside the outer protection tube 2, plug neck 31
Lower end center is equipped with to concave first blind hole 311 in 32 direction of cock cap, and the upper-center of cock cap 32 is equipped with recessed to 31 direction of plug neck
The second sunken blind hole 321, the first blind hole 311 and the second blind hole 321 are not connected.Protective cap 4 is set in 32 extension of cock cap
Outside, the position that protective cap 4 corresponds to the second blind hole 321 is equipped with through hole 41, the one side of protective cap 4 and the pipe of the outer protection tube 2
Mouth outer wall rotation connection, so that protective cap 4 is overturn around the nozzle of the outer protection tube 2.
When in use, the inner-wall spraying of internal layer collection tube 1 has anticoagulant, and the tube wall of internal layer collection tube 1 is in from top to bottom
Wave structure can increase the internal surface area of internal layer collection tube 1, and anticoagulant is in the distribution area of 1 tube wall of internal layer collection tube
It can increase, and blood more difficult bottom for flowing to internal layer collection tube 1 on the tube wall of wave structure, so as to blood energy and tube wall
On anticoagulant come into full contact with.
When needing to extract rubber stopper 3, protective cap 4 only need to be pushed up, protective cap 4 is around the nozzle with the outer protection tube 2
Overturning at rotation connection, drives rubber stopper 2 to extract internal layer collection tube 1, the outer protection tube 2, completes to open, whole process stabilization,
Gently, spilling for sample, rubber stopper 3 will not be caused to be connected to after extracting with protective cap 4 on the outer protection tube 2；When needs are filled in
During rubber stopper, only 4 reverse flip of protective cap need to be pressed the sealing that heparin tube can be realized in protective cap 4.For the ease of protective cap
4 promote, and in the present embodiment, the opposite side of protective cap 4 is equipped with the brim of a hat 42.The brim of a hat 42 can facilitate 4 stress of protective cap.
It, can be true after assembling product since internal layer collection tube 1 and the outer protection tube 2 are to be assembled under vacuum conditions
The gap that the inner wall of the outer wall and the outer protection tube 2 of protecting internal layer collection tube 1 is formed is vacuum environment, is blocked water to the choke of product
Optimal effect is played, due to rational in infrastructure, industrialized production be very suitable for, advantageously reduce production cost.
Since plug neck 31 and cock cap 32 are respectively provided with the first blind hole 311 and the second blind hole 321 that are recessed inwardly so that medical care
Personnel can reduce penetration Resistance during rubber stopper 3 is punctured, so as to reduce the finger fatigue for puncturing bring for a long time.
It is the structure diagram of the medical vacuum blood collection tube of the utility model second embodiment refering to Fig. 2.The present embodiment
Medical vacuum blood collection tube and the medical vacuum blood collection tube of first embodiment the difference is that, the nozzle of the outer protection tube 2
Outer wall is equipped with boss 21 with holes, and the one side of protective cap 4 passes through rotation connection with boss 21 with holes.The protective cap 4 of the present embodiment can
It is overturn around boss 21 with holes, remaining attached on boss 21 with holes after overturning（As shown in Figure 3）.
By the above-mentioned means, protective cap and rubber stopper are set in together by the medical vacuum blood collection tube of the utility model,
The nozzle of protective cap and the outer protection tube is rotatablely connected, it is necessary to when extracting rubber stopper, need to only push up protective cap, protective cap and
Rubber stopper is rotated using the junction of protective cap and the outer protection tube as fulcrum, and the rubber stopper compared to existing heparin tube does phase
To linear motion, reduce needed for unlatching firmly, so as to which rubber stopper is facilitated to be separated with nozzle.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly used in
