The specific embodiment
As shown in Figure 1, the disposable all-plastic self-destruction syringe of the present invention comprises syringe 1, push rod 2, and push rod 2 is movably set in the syringe 1; The head of push rod 2 is provided with packed-piston head 22.The porch of syringe 1 is provided with cylinder seat 3, and cylinder seat 3 forms card containing cavity 31 with the afterbody of syringe 1.The afterbody of push rod 2 is provided with two or more cards 21, and the head of card 21 is up-small and down-big taper; Card 21 is circumferentially uniform along push rod 2, and card 21 is connected with push rod 2 by connecting neck 211.
As shown in Figure 2, packed-piston head 22 comprises piston body 221, and the outer ring of piston body 221 is provided with two circle piston rings 222, forms M type cavity 223 between piston ring 222 and the piston body 221, M type cavity 223 can increase the elasticity of packed-piston head 22, guarantees the sealing between push rod 2 and the syringe 1.
The present invention is provided with packed-piston head 22 at the head of push rod 2, can play the effect of supercharging, negative pressure.
The piston body 221 of packed-piston head 22 can be various structures.
As shown in Figure 3, the middle part of piston body 221 is provided with groove, is used for being connected with syringe needle.
As shown in Figure 4, the middle part of piston body 221 is provided with piston boit, is used for cooperating with the head of syringe 1.
As shown in Figure 5, during use, push rod 2 is pushed in the syringe 1, along with pushing of push rod 2, card 21 enters card containing cavity 31, and is withstood afterbody by cylinder seat 3, card 21 can't be pushed out from card containing cavity 31, thereby prevent from reusing.
Packed-piston head 22 can adopt the various medical non-toxic plastics such as polyethylene, polypropylene to make.
The present invention is provided with card 21 at the afterbody of push rod 2, and card 21 can stop push rod 2 to be drawn out after injection, plays the function of self-destruction, thereby prevents from reusing.
