Abstract
An instrument for protecting the user of a medical syringe from being pricked by its needle when unsheathing or resheathing the needle. The instrument has an upper member releasably mounted atop a disposable container. A vertical passage through the upper member empties through a hole into the container. The passage has a coned entry mouth enabling the user to guide the sheathed needle end of a syringe into the passage. A cam in the upper member is pivotable to hold the sheathed needle in the passage, so that the user may pull on the syringe and separate its needle end from the sheath; or later, the user may reinsert the used needle end of the syringe into the cammed sheath and, upon twisting the syringe, separate it from the needle to allow the separated resheathed needle to drop into the container following release of the cammed condition; or the user may in the latter case instead of twisting the syringe simply release the cammed condition to allow the resheathed needle attached to the syringe to be withdrawn from the instrument.
