Abstract
Abstract An apparatus for safely handling a needle while removing the needle from a substrate such as an implanted access device having a resealable septum. The apparatus has a distal end and a proximal end and comprises a body, a cap member, and a basin-shaped member. The body defines interior boundaries and the cap member has an opening therein. The cap member is connected to and is distal to the body. The basin-shaped member defines a self-closing passageway and has a rim connected to the body. The rim of the basin-shaped member is disposed within the interior of the body intermediate the cap member and the proximal end of the apparatus. The basin-shaped member has an apical end facing the distal end of the apparatus. The cap member includes two resilient flaps, offset from one another. In one arrangement, the cap member and the body snap together to trap the basin-shaped member. In another arrangement, the apparatus is made of two identical halves joined together. An adapter is provided to facilitate use of the apparatus with small ports.
