ABSTRACT:
A single-use, hypodermic syringe which disables itself during its initial application thereby preventing any subsequent use of the syringe. The working parts of the invention are designed to separate automatically when the syringe is oriented into the solution dispensing mode. These separated parts prevent subsequent aspiration of solutions into the syringe thereby rendering the syringe inoperable and unuseable after its initial use.
