Abstract
A single-use needle cover configured to obscure, protect, or hide at least a portion of a needle from view before, during, and/or after an injection and/or aspiration procedure is disclosed. In some embodiments, the cover includes a housing at least partially containing the needle and configured to couple to a syringe, wherein the housing includes an axis and a guide member. In some embodiments, a sleeve has a plurality of tracks configured to slidingly receive the guide member, wherein the sleeve is configured to retract, extend, and rotate with respect to the housing. In some embodiments, after the sleeve has been retracted and extended one time, a first locking member inhibits further retraction of the sleeve and a second locking member inhibits rotation of the sleeve.
