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.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of resilient safe transfusion system of syringe needle, including Perfusion tube 2, one end of the perfusion tube 2 are fixed at infusion niidl 4, and the outer cover of the infusion niidl 4 is equipped with plastic needle guard 5, the outer cover of described 2 one end of perfusion tube is equipped with recovery tube 1, and one end of the recovery tube 1 and the outer wall of the perfusion tube 2 are fixed Connection, the other end of the recovery tube 1 are fixed with guiding pullover 3, and the perfusion tube 2 is inserted through inside the guiding pullover 3 Through-hole, one end inside the recovery tube 1 is fixedly connected with stretch cord 8, and the side wall fixation of the other end is set in the recovery tube 1 There are two fixed block 6, the middle part of two fixed blocks 6 offers the first opening 7, and the side wall of described 8 one end of stretch cord is solid Surely it is connected with interspersed set 9, the middle part of the interspersed set 9 offers the second opening 10, one of them described first opening 7, second Opening 10 and another described first opening 7 are successively interted by thin slice 11, and the thin slice 11 is inserted through the one of the recovery tube 1 Side, and one end of the thin slice 11 is fixedly connected with knob 12.

Two it is described first opening 7 size with it is described second opening 10 size it is identical, facilitate the thin slice 11 into Row is interspersed；The width of the perfusion tube 2 is 2-3cm, and the width of the recovery tube 1 is 8-12cm, so that tool in the recovery tube 1 There is sufficient space to recycle the perfusion tube 2 and the infusion niidl 4；The thin slice 11 is suppressed by paper material, reduction pair It is polluted caused by environment；The recovery tube 1 and two fixed blocks 6 are made of transparent polyethylene material, and cost of material is low And facilitate the inner case for observing the recovery tube 1；The pipe thickness of the recovery tube 1 is greater than 1cm, prevents infusion niidl 4 from piercing Wear the recovery tube 1.

Working principle: when the utility model works, firstly, remove plastic needle guard 5, perfusion tube 2 is connected to drug, to patient into Row normal infusion, after the completion of infusion, medical staff pulls dynamic knob 12, pulls out thin slice 11, loses the holding power of thin slice 11, Interspersed set 9 loses the pulling force to stretch cord 8, under the elastic force effect of stretch cord 8, perfusion tube 2 along guiding pullover 3 through-hole to returning Recycling in closed tube 1, when stretch cord 8 restores nature, infusion niidl 4 is recovered in recovery tube 1, completes infusion niidl 4 Recycling, abandoned transfusion system can be focused on.
