Abstract
The invention provides an auto-disable syringe for overcoming the defects that an existing auto-disable syringe is complex in structure, high in product cost, incomplete in auto-disable degree and the like. A stopper (4) positioned in a piston (2) is connected with a piston rod (5); an airbag (6) is arranged in the stopper (4); a pricking pin (3) is arranged on a hollow edge on the outer side of the piston (2). The auto-disable syringe is simple in structure, simple in production and complete in auto-disable degree, repeated use of disposable syringes can be effectively avoided, and the health of patients is effectively protected.
Description
Technical field
The present invention relates to medical instruments field, specifically a kind of self-destruction syringe.
Background technology
There is many weak points such as complex structure, product cost is high, self-destruction degree is thorough not in existing self-destruction syringe.
Summary of the invention
For solving existing self-destruction syringe, there is the deficiencies such as complex structure, product cost is high, self-destruction degree is thorough not, the invention provides a kind of self-destruction syringe.
The present invention is achieved in that washer (4) is connected with piston rod (5) in piston (2), is provided with air bag (6) in washer (4), and the hollow edge in piston (2) outside is provided with pricker (3).
Air bag (6) support washer (4) is umbrella shape and scatters.
After air bag (6) is punctured, loses the washer (4) that air bag (6) supports and automatically reset boundling together, what can not be subject to that piston (2) stops freely pulls out, thereby piston (2) is not pulled out again, realizes self-destruction.
The invention has the beneficial effects as follows: simple in structure, be easy to produce, self-destruction is thorough, can effectively prevent reusing of disposable syringe, effectively protects sufferer healthy.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, be described further.
Fig. 1 is structural representation of the present invention.
In figure 1, syringe, 2, piston, 3, pricker, 4, washer, 5, piston rod, 6, air bag.
The specific embodiment
As shown in the figure, in piston (2), washer (4) is connected with piston rod (5), is provided with air bag (6) in washer (4), and the hollow edge in piston (2) outside is provided with pricker (3), and air bag (6) support washer (4) is umbrella shape and scatters.
While using first, piston (2) is in syringe (1) top, pricker (3) not with air bag (6 contact), pull piston rod (5) to draw injection, the pricker (3) at hollow edge, piston (2) outside punctures air bag (6), realizes self-destruction, because washer is now subject to the outside pulling force impact of piston rod (5), piston (2) outside has stoped the reset of washer, and washer (4) can continue to pull piston (2) to draw injection; During injection, front the pushing away of piston rod (5), what washer (4) had lost piston (2) lateral wall stops rapid reset boundling together, continues to promote piston rod (5) and completes injection; While being again pulled outwardly piston rod (5), boundling washer (4) is together unobstructed to be extracted out in piston (2), cannot again draw injection.
Claims (3)
1. a self-destruction syringe, is characterized in that, the interior washer of piston (2) (4) is connected with piston rod (5), is provided with air bag (6) in washer (4), and the hollow edge in piston (2) outside is provided with pricker (3).
2. a kind of self-destruction syringe according to claim 1, is characterized in that, air bag (6) support washer (4) is umbrella shape and scatters.
3. a kind of self-destruction syringe according to claim 1, is characterized in that, after air bag (6) is punctured, washer (4) reset boundling together.
