Piece lower end has card slot；
The through-hole is arranged on fixed block；
The fixture block is matched with card slot.
The working principle of the invention and process:
Original state, anti-dropout elastic covering are not switched on, several anti-flakes of elasticity on anti-dropout elastic covering are vertical state,
Medical staff first by present invention insertion infusion bottle, pushes push jack then up and withstands on infusion bag lower end, in the process, prevent
The elastic covering upper end that falls off is fixed, and lower part moves up, effect of several the anti-flakes of elasticity on anti-dropout elastic covering in extruding force
Under heave, increase diameter of the infusion apparatus inside bottle body, syringe needle for transfusion device made to be not easy to fall off from infusion bottle or transfer to, anti-
Elastic covering lower part fall off when move up, when being moved to certain position, the card slot on anti-dropout elastic covering and are set
Fixture block contact on one elastic rod, fixture block stick into card slot, keep several anti-flakes of elasticity to heave, prevent from falling off, be arranged in ring
Leakproof elastic washer in connected in star shuts the gap among anti-dropout elastic covering and syringe needle for transfusion device, prevents the medicine in infusion
Liquid prolongs the outflow of the gap among anti-dropout elastic covering and syringe needle for transfusion device.
After the completion of infusion, medical staff pins button, and card slot and fixture block are detached from, the effect of anti-dropout elastic covering screen resilience
Lower reinstatement, lantern-shaped structure disappear, can extract infusion apparatus.
Beneficial effects of the present invention:
The present invention effectively can avoid syringe needle for transfusion device from surprisingly falling off, and prevent children or the dry dynamic patient of stupor by infusion apparatus needle
Head is extracted；Avoid drug or blood loss；Prevent pollution environment；Workload increases caused by avoiding medical staff from falling off because of syringe needle
Adduction avoid patient or family members therefore caused by scaring and worry；Reduce health resources waste；Reduce medical treatment and nursing accident
Occur and reduce infusion cost.

Specific embodiment
It please refers to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of anti-dropout infusion device syringe needle, including infusion apparatus needle
First 1 and anti-dropout elastic covering 2,1 upper end of syringe needle for transfusion device has fixed block 3,2 sets of anti-dropout elastic covering in syringe needle for transfusion device 1, and
And upper end is fixed on fixed block 3；
1 lower end of syringe needle for transfusion device has leakproof elastic washer 4, and 4 outer wall of leakproof elastic washer and falls elastic covering 2
Sealing cooperation；
1 lower end of syringe needle for transfusion device is respectively provided with the first infusion hole 11, the second infusion hole 12, the first elastic rod 13,
Two elastic rods 133, annular groove 14, the first rectangle sliding slot 15 and the second rectangle sliding slot 16, the first elastic rod 13 and the second elasticity
133 structure of bar is identical, and the first infusion hole 11 and the distribution of the second infusion hole 12 are arranged in 1 lower end of syringe needle for transfusion device, leakproof elastic cushion
Circle 4 is arranged in annular groove 14, and the first elastic rod 13 is arranged in the first rectangle sliding slot 15, and the setting of the second elastic rod 133 exists
In second rectangle sliding slot 16；
13 upper/lower terminal of elastic rod is respectively provided with button 131 and fixture block 132；
2 upper end of anti-dropout elastic covering is provided with through-hole 21, and centre has several anti-flakes 22 of elasticity, and lower end, which has, to push away
Piece 23,23 lower end of push jack have card slot 24；
The through-hole 21 is arranged on fixed block 3；
The fixture block 132 is matched with card slot 24.
The working principle of the invention and process:
It please refers to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, original state, anti-dropout elastic covering 2 is not switched on, anticreep
Several the anti-flakes 22 of elasticity fallen on elastic covering 2 are vertical state, medical staff first by present invention insertion infusion bottle, then to
Upper promotion push jack 23 simultaneously withstands on infusion bag lower end, and in the process, 2 upper end of anti-dropout elastic covering is fixed, and lower part moves up, and prevents
Several the anti-flakes 22 of elasticity to fall off on elastic covering 2 are heaved under the action of extruding force, increase infusion apparatus inside bottle body
Diameter makes syringe needle for transfusion device be not easy to fall off from infusion bottle or transfer to, when 2 lower part of anti-dropout elastic covering moves up,
When being moved to certain position, the card slot 24 being arranged on anti-dropout elastic covering 2 is contacted with the fixture block 132 on the first elastic rod 13,
