Abstract
An elongate cylindrical body portion and a spoon-shaped shield member are injection molded as a single unitary piece of transparent polypropylene. The cylindrical body portion has a longitudinally extending slot so that it can be readily snapped around the barrel of a syringe. The spoon-shaped member extends from the forward end of the body portion. This member can deflect transversely from an un-deflected non-use configuration to a slightly deflected in-use configuration to permit the needle to extend therebeyond when the guard is installed with the body portion in a retracted position relative to the barrel of the syringe. When the body portion of the guard is manually slid to an extended position relative to the syringe barrel, the spoon-shaped member returns to its un-deflected configuration and the tip of the needle is engaged by a plurality of ribs formed on an inner wall of the spoon-shaped member. The tip of the needle is thus concealed and accidental puncture thereby is avoided.

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.
