Abstract
A syringe structured to permit multiple filling and emptying cycles with a single syringe, but then to automatically disable that syringe to resist syringe reuse subsequent to a final dose-ejecting cycle. The syringe includes a plunger with a distal tip carrying capture structure that protrudes from the dispensing aperture of the syringe at a fluid fully-expelled position. A fluid discharge attachment can be coupled to the syringe to guide dispensing one or more dose of treatment substance. A first locking element, typically carried by the fluid discharge attachment, couples with the capture structure to resist retraction of the fully-depressed plunger, and thereby resists reciprocation of the plunger to prevent reuse of the syringe. Effectively, the discharge aperture of the syringe is pinned between an internally disposed stopper and the external capture structure. A stem of the plunger may optionally be structured to detach, leaving the stopper behind inside the syringe body, to further frustrate reuse of the syringe. Sometimes, a second locking element may be included to also resist unscrewing a fluid discharge device from a syringe.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
