Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of Novel hemostix rubber plug as shown in Figs. 1-3, including plug hat 1 and plug neck 2, plug hat 1 bottom is fixedly connected with plug neck 2, and the inside of plug hat 1 is embedded with support plate 7, and the both ends of support plate 7 are fixedly connected in arc The soft bar 8 of elasticity of shape shape, the bottom end of support plate 7 are fixedly connected with ellipse shape fixed block 9, and the ellipse insertion of shape fixed block 9 is filled in inside neck 2 In the fluting opened up, the bottom end of ellipse shape fixed block 9 is fixedly installed with several limited blocks 10, offers in the cell wall of fluting several A limiting slot to match with limited block 10, limited block 10 are embedded in limiting slot, and the inside of plug neck 2 offers cavity 5.

Further, in the above scheme, the diameter of plug hat 1 is greater than the diameter of plug neck 2, the junction of plug hat 1 and plug neck 2 Card slot is offered, the side of card slot cell wall is fixedly installed with several convex blocks 11, increases rubber plug and blood sampling spout by convex block 11 Between leakproofness.

Further, in the above scheme, the center position at 1 top of plug hat offers shrinkage pool 11, and the avris of plug hat 1 is viscous Non-slip mat 4 is posted, is assembled and is broken seal convenient for pinching 1 two sides of plug hat with hand.

Further, in the above scheme, the material of plug hat 1 and plug neck 2 is fluorubber material, and support plate 7, ellipse shape are solid The material for determining block 9 and limited block 10 is polyvinyl chloride, and fluorubber inoxidizability, good corrosion resistance, polyvinyl chloride has fine Toughness and ductility.

Further, in the above scheme, the side for filling in neck 2 offers screw thread 3, and the bottom of plug neck 2 is arc shape, increases Fill in the frictional force of neck 2 and inside pipe wall of taking a blood sample.

This practical working principle: after heparin tube has acquired blood sample, rubber plug is fitted into heparin tube, staff is pinched with hand Plug neck 2 is directed at blood sampling spout, turns plug hat 1 with hand by the firmly two sides of plug hat 1, make to fill in direction that neck 2 is rotated according to screw thread 3 into Enter in heparin tube, the nozzle of heparin tube is caught in card slot, contacts convex block 11 and the outer wall of test tube mouth, guarantees its leakproofness, empty The diameter of chamber 5 changes with the pressure difference inside and outside hemostix test tube and is changed, and plays good buffer function to plug neck 2, makes to fill in neck 2 It is unlikely to deform；

When break seal rubber plug when, when being preced with 1 two sides with hand pinching plug, effect of the soft bar 8 of elasticity at 7 both ends of support plate by external force Mobile toward relative direction, the diameter of recess 6 becomes smaller, and after unpacking, the soft bar 8 of two elasticity is mobile toward opposite direction, 6 diameter of recess It is returned to original size, plug hat 1 is returned to original shape.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
