ABSTRACT:
An improved syringe for administering injections includes a syringe barrel with an interior chamber, a reciprocating plunger within the chamber, a needle flow communicating with one end of the chamber and a mechanism for removing the needle by remote manipulation by the administrator of an injection without directly touching the needle. The mechanism includes a projection extending radially outward from the needle that is selectively engageable by a projection receiving slot on a sleeve mounted over the barrel. The sleeve loosely fits on the barrel so as to be slidable and rotatable and includes a first configuration wherein the sleeve does not engage the needle, a second configuration wherein the slot engages the projection to allow a user to rotate and disengage the needle and a third configuration wherein the sleeve extends over the needle to protect a user from being accidentally stuck by the needle after use.
