The specific embodiment

Below be embodiment of the present utility model to be described, have in the affiliated technical field and know that usually the knowledgeable can understand other advantages of the present utility model and effect easily by the content that this description disclosed by particular specific embodiment.

Please cooperate and consult shown in Fig. 1-3, this utility model is a kind of high-safety injection tube, and it has a sleeve 1, an elastic component 2, an inner core 3 and a push rod 4.

Sleeve 1 has a perforation 10, the perisporium of sleeve 1 is formed with two relative guide rails 11, each guide rail 11 have be interconnected one slide a rail 110 and a check rail 113, has a guide plate 112 in sliding the place of connection of rail 110 with check rail 113, an end that slides rail 110 has a block 111, one end of check rail 113 has a check piece 114, the inwall of perforation 10 has two relative interior rails 100, edge in perforation 10 has two relative fixed leg 12 and fastening pieces 13 in addition, and each fixed leg 12 is adjacent to 100 places of rail in each.

Elastic component 2 is located in the perforation 10, the central authorities of elastic component 2 have a clipping ring 20, the two ends of elastic component 2 have an extending pin 21 respectively, the free end of extending pin 21 has a fixing hole 22, each extending pin 21 is arranged in each rail 100, each fixing hole 22 wears for each fixed leg 12, and elastic component 2 is made by plastic material or rubber material.

One end of inner core 3 is arranged in the perforation 10, this wears end and has a needle stand 30, needle stand 30 other ends are provided with a syringe needle 300, and needle stand 30 and clipping ring 20 mutual clips, the perisporium of inner core 3 and have two relative guide pillars 31 adjacent to needle stand 30 places, each guide pillar 31 is arranged in each guide rail 11, and the other end of inner core 3 has two relative fins 33, and in the perisporium of this end and have a button hole 32 between two fins 33, button hole 32 is alternative to fasten mutually with fastening piece 13.

Push rod 4 is arranged in the inner core 3 by the end that inner core 3 has fin 33.

Please cooperate and consult shown in Fig. 4-6, inner core 3 is pushed in the sleeve 1, because of combining of fixed leg 12 and fixing hole 22, and needle stand 30 and clipping ring 20 mutual clips, so that extending pin 21 pullled, and extension in interior rail 100.

Simultaneously, guide pillar 31 can break away from the state that fastens mutually with block 111, and moves in sliding rail 110, arrive at guide plate 112 positions until guide pillar 31, and fastening piece 13 can mutually combine with button hole 32, is subjected to the elastic force of elastic component 2 to avoid inner core 3, and returns back to its initial position.

And by the syringe needle 300 that protrudes sleeve 1, to reach the effect of injection, after aforesaid injection is finished, can press fastening piece 13,, be subjected to the influence of the elastic force of elastic component 2 so that fastening piece 13 is separated from each other with button hole 32, sleeve 1 its initial position that rebounds immediately is to be contained in syringe needle 300 bags wherein.

When sleeve 1 moves; guide pillar 31 is subjected to the guiding of guide plate 112; and enter in the check rail 113; when sleeve 1 is got back to its initial position fully; guide pillar 31 is also by check piece 114; if this moment; when desire pushes inner core 3 in the sleeve 1 once more; guide pillar 31 can be subjected to fastening of check piece 114; it can't be moved in check rail 113; make inner core 3 to push once more in the sleeve 1 whereby, and promptly discardable through used high-safety injection tube of the present utility model, and reach the effect of protecting the healthcare givers.

See also shown in Figure 7, be another possible embodiments of this utility model, its high-safety injection tube also can be used for blood drawing, is a storage blood card casket 5 is set in inner core 3, the one end is communicated with syringe needle 300, then be slidingly equipped with a pull bar 51 in the other end, when borrowing pull bar 51 row upwards to move apart storage blood card casket 5 with the blood sucking-off, treat that blood drawing is finished after, then can press fastening piece 13, make inner core 3 bullets from sleeve 1, and syringe needle 300 is contained in the sleeve 1, reach the security maintenance effect; In addition, please consult shown in Figure 8ly again, this storage blood card casket 5 ' also can be a single formula bottle (medical), is vacuum state in it, to borrow vacuum principle draw blood.

The above-described specific embodiment of thought, only be to be used for example to release characteristics of the present utility model and effect, but not in order to limit the category of implementing of the present utility model, do not breaking away under the spirit and technology category of taking off on this utility model, any utilization this utility model institute's disclosure and the equivalence finished changes and modify all still should be following claim and contains.
