Sub illegal recycling is reused.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure is simple, design rationally,
The not recyclable safety self-destructing insulin syringe reused.
To solve the above problems, technical solution used by the utility model is as follows:
A kind of safety self-destructing insulin syringe, including syringe, push rod and piston, the push rod and piston setting
In in the syringe, the piston is set to one end of the push rod, and one end of the syringe is equipped with connector, the connector
Interior to be equipped with the fluid bore being connected to inside the syringe, the bottom in the syringe is equipped with protrusion, and the end of the protrusion is equipped with
Clamping joint is formed with snap-latch surface between the clamping joint and the protrusion, and the clamping joint is set in the syringe bottom
At the heart, the connector is located at the side of the clamping joint, is equipped with the card slot for accommodating the clamping joint in the piston, and described
Piston base is equipped with the through-hole being connected with the card slot, and the through-hole is located at the surface of the protrusion.
Further, the clamping joint is conical structure, and the clamping joint top diameter is less than base diameter.
Further, the side of the piston is equipped with annular groove.
Further, the top of the piston is equipped with the link slot for connecting the push rod, is equipped in the annular groove
The bayonet being connected with the link slot.
Further, one end of the push rod is equipped with link block, and the link block is set in the link slot, and described
The width of link block is greater than the width of the push rod, and the side of the link block is evenly equipped with multiple in mating connection with the bayonet
Strip.
Compared with prior art, the utility model has the beneficial effects that: piston is in the bottom of syringe after injection
Portion, and in the through-hole of protrusion insertion piston base, clamping joint is located in card slot, is securely seated between clamping joint by snap-latch surface
In card slot, this piston can not just be reused, and entire damage process is automatically performed with injection process, to effectively prevent
Syringe is recovered and reuses, and brings harm to patient, structure is simple, and use is safe.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of piston in the utility model；
Fig. 3 is the structural schematic diagram of push rod in the utility model；
In attached drawing, 1 is syringe, and 2 be push rod, and 3 be piston, and 4 be connector, and 5 be fluid bore, and 6 be protrusion, and 7 be clamping joint,
8 be card slot, and 9 be through-hole, and 11 be annular groove, and 12 be link slot, and 13 be bayonet, and 14 be link block, and 15 be strip.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Such as Fig. 1 to Fig. 3, a kind of safety self-destructing insulin syringe, including syringe 1, push rod 2 and piston 3, the push rod
