ABSTRACT:
A recapping device is provided for use with medical devices including all hollow and solid medical needles of the type used for entry into the body and into closed intravenous and intraarterial systems for access, sampling, and injection of medications, and are withdrawn after use. The recapping device includes a hollow sleeve encircling a portion of the needle and having a distal end aperture adapted to permit the sleeve to slide between a first position on the medical device wherein the needle is exposed to enable use of the needle, and a second position characterized by the distal end of the needle being contained within the distal end capped hollow sleeve, and the device may optionally contain a housing for a free-floating fenestrated disk, which, upon movement of the device to its second position wherein the tip of the needle exits the distal end aperture, shifts position to provide an obstruction at that aperture. A securing means for the hollow sleeve, such as a tether, is provided for permitting substantially free slidable movement of the hollow sleeve between the first and second positions.
