Disposable self-destructible syringes which render themselves unreusable
First Claim
1. A disposable syringe which renders itself non-reusable which comprises a rigid cylinder coupled at one end to a bottom wall with an opening for the exit of the solution to be injected, and having the other end open, said end being integrally coupled to support flanges which extend outwardly and perpendicularly to the axis of the cylinder, and a plunger with a piston at the extreme end coupled to the cylinder, the piston having at least one punch rod which extends parallel to the longitudinal axis of the cylinder and is adapted to engage or puncture the bottom wall of said cylinder so as to prevent reuse.

Abstract
This invention refers to disposable syringe containers used for injection which destroy themselves and render themselves unreusable, characterized principally in that they are made of a material which can be cut or perforated with the normal injecting movement of the piston in the syringe, thus destroying them and which have parts which engage the piston to the cylinder or to the injection needle after the first use and prevent any further use of the syringe.
