ABSTRACT:
The invention provides a protective sheath for an intermittent I.V. therapy needle to protect medical personnel against accidental self puncture while performing intermittent I.V. therapy. The sheath is a flexible transparent plastic tube having an internal septum which provides two separate interior compartments. One compartment is adapted to house a needle and a portion of the needle hub, providing an enclosed sterile environment when the device is attached to the needle assemblage of a secondary medication source. The second compartment is adapted to be releasably affixed to the exterior of an eccess port at a Y-site located on intravenous tubing used for intermittent I.V. therapy. The walls of the sheath fold and compress as the needle is advanced through the internal septum into the Y-site where the contents of the secondary medication source are infused into the I.V. tube main line through the Y-site. Upon removal of the needle from the Y-site, the septum reseals and the tubular wall of the sheath through material resilience assume the original elongated shape. A pull is required to release the attachment end of the sheath from the Y-site port which also helps straighten out the sheath tube. When sufficient pull is exerted to release the sheath from the Y-site head, the needle is fulley encased in the needle housing preventing premature exposure. The encased needle can be safely disposed of or, in some cases, reused on the same patient with the same medication. The device is also useful with syringes.
