ABSTRACT:
Parts integrally associated with a shortened I.V. insertion needle handle to provide, in as few as one molded part, an extendable safety guard for a catheter insertion needle and its sharpened tip. The safety guard comprises a plurality of rigid segments serially connected by a plurality of living hinges. The segments are disposed about the insertion needle, folded upon each other during the medical procedure and extended at the end of the procedure to form a secure, substantially fixed length safety sheath which conforms to the long axis of the needle. During the procedure, the safety guard is folded and conveniently disposed about a proximal portion of the needle. At the end of the procedure, the safety guard is extended by a relatively short motion associated with an arc distance of a proximal segment of the enclosure to protectively guard and secure the needle. The needle becomes a part of a structure which is cooperatively formed by both needle and enclosure. The resulting structure has a fixed, predetermined length and protects from inadvertent exposure to the needle tip.
