Abstract:
A safety syringe ( 100; 700; 1200 ) comprising: a barrel ( 104; 704; 1204 ) having an opening at an end thereof; a syringe plunger ( 108; 708; 1208 ) configured to move within the barrel such that an inward stroke of the syringe plunger causes a substance within the barrel to be expelled from the opening; and a sheath ( 112; 712; 1212 ) configured to cover at least partially the opening in the barrel after use of the syringe, wherein the sheath is coupled to the syringe plunger and is configured to decouple from the syringe plunger at a point on the inward stroke such that the sheath is moveable independently of the syringe plunger and further movement of the sheath after decoupling at least partially covers the opening in the barrel.

Claim (Index 20):
A kit of parts comprising:\n a safety plunger configured to be coupled to a syringe plunger of a syringe such that an inward stroke of the safety plunger causes the syringe plunger to move forward within the barrel; and a sheath configured to be deployed by the safety plunger so as to cover at least partially an opening in a barrel of the syringe after use of the syringe, wherein the safety plunger is configured to be coupled to the sheath and is configured to decouple from the syringe plunger at a point on the inward stroke such that the safety plunger is moveable further forward independently of the syringe plunger, wherein the further forward movement of the safety plunger after decoupling of the safety plunger from the syringe plunger causes the sheath to move further forward to at least partially to cover the opening in the barrel, and wherein the syringe plunger comprises at least one rotation surface configured to rotate the syringe plunger for a portion of the inward stroke of the safety plunger.
