ABSTRACT:
A protective covering and method of use for preventing contamination of a syringe used to deliver material to a surface, so as to permit subsequent reuse of the syringe. The syringe comprises a barrel containing the material, a plunger for expelling the material from the barrel, and a removable delivery tip. The protective covering includes a collapsible sleeve for enclosing the syringe so as to provide a barrier to protect the syringe from contamination by an environment. A first and a second portion form the collapsible sleeve. The first portion has a width greater than the widest portion of the syringe. The second portion has a width smaller than the first portion which conforms to the width and length of the barrel so as to provide a snug fit around the barrel. An aperture is formed at the end of the collapsible sleeve through which a portion of the removable delivery tip passes when the syringe is inserted into the sleeve so that that portion of the tip is exposed to the outside environment. The collapsible sleeve may be heat sealed around the syringe. Once the syringe has been used, the syringe may be removed from the sleeve without being contaminated. The removable delivery tip is removed while the syringe is still enclosed within the sleeve.
