Title
(EN) iRE-SLIT INJECTION SITE AND TAPERED CANNULA
(FR) SITE D'INJECTION PRE-FENDU ET CANNULE CONIQUE
Abstract
(EN)
A pre-slit injection site (34) includes a housing (40) with a flow path therethrough. A first end (42) of the housing (40) carries a pre-slit septum (52). One form of a blunt cannula (98), usable with the injection site (34), carries a locking member (100). When the pre-slit injection site (34) slidably receives the blunt cannula (98), the locking member (100) latches to the injection site (34) and creates a mechanically coupled unit. Another form of the cannula (280) includes a tube having a tapered distal end region (298) and having elongate discharge slots (294) for reducing contact surface area and for directing the flow laterally out of the cannula. The cannula may also include a rounded lead post (330), an annular barb (394), and axially oriented grooves (268). A blood sampling system utilizing an in-line pre-slit injection site (492) and a shielded blunt cannula (512). An adapter for transferring fluids from a syringe with a blunt cannula to an evacuated tube, including a pre-slit injection site (554) and a shroud covered needle (556) with a rubber sleeve.
(FR)
Site d'injection pré-fendu (34) comprenant un logement (40) pourvu d'un passage d'écoulement. Ledit logement (40) comporte à sa première extrémité (42) un septum pré-fendu (52). Une forme de cannule épointée (98), que l'on peut utiliser avec ledit site d'injection (34), porte un élément de verrouillage (100). Lorsque la cannule épointée (98) est glissée dans le site d'injection pré-fendu (34), l'élément de verrouillage (100) verrouille le site d'injection (34) et forme ainsi une unité d'accouplement mécanique. Une autre forme de cannule (280) comprend un tube ayant une région terminale distale conique (298) et des fentes de décharge allongées (294) pour réduire la surface de contact et pour diriger latéralement le flux hors de la cannule. La cannule peut également comprendre une protubérance de plomb arrondie (330), un prolongement annulaire (394), et des rainures orientées axialement (268). Dans un système d'échantillonnage du sang on utilise un site d'injection pré-fendu en ligne (492) et une cannule épointée protégée (512). Un adaptateur permet de transférer les fluides de la seringue au moyen d'une cannule épointée vers un tube d'évacuation, comprenant un site d'injection pré-fendu (554) et une aiguille à enveloppe de protection (556) pourvue d'un manchon en catoutchouc.
