A medical needle apparatus comprising parts, which may be integrally moulded with a phlebotomy barrel or with a Luer fitting to provide, in a single moulded part, an extendable safety enclosure (140) for a medical cannula (40) in phlebotomy, syringe and other general medical needle applications. Integrally moulded part phlebotomy safety devices are disclosed which require only the integrally moulded part (110); a medical needle (40), a label and a transport needle cover to form a ready-to-use phlebotomy device. Upon removal of the label and needle cover, the device is ready for use in a medical procedure. The enclosure (140) comprises a plurality of rigid segments (150, 160, 170) serially connected by a plurality of intersegment hinges, which are preferably living hinges. The segments are disposed about a medical needle (40), folded upon each other during the medical procedure and extended at the end of the procedure to form a secure, substantially rigid safety shroud (140). During the procedure, the enclosure (140) is folded and conveniently disposed about a proximal portion of the needle (40). At the end of the procedure, the enclosure (140) is extended to protectively sheath and secure the needle (40) in a substantially rigid structure formed in combination by the enclosure (140) and the needle (40). |
