Document Type and Number:
Japanese Patent JP4908534
Kind Code:
B2
Abstract:
Parts which may be integrally molded with a phlebotomy barrel or with a Luer fitting to provide, in a single molded part, an extendable safety enclosure for a medical cannula in phlebotomy, syringe and other general medical needle applications. Integrally molded part phlebotomy safety devices are disclosed which require only the integrally-molded part, a medical needle, 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 comprises a plurality of rigid segments serially connected by a plurality of intersegment hinges, which are preferably living hinges. The segments are disposed about a medical needle, folded upon each other during the medical procedure and extended at the end of the procedure to form a secure, substantially rigid safety shroud. During the procedure, the enclosure is folded and conveniently disposed about a proximal portion of the needle. At the end of the procedure, the enclosure is extended to protectively sheath and secure the needle in a substantially rigid structure formed in combination by the enclosure and the needle.
