Patent

CA 2296701

A needleless connector (450) is provided which utilizes a resealable preslit septum valve (402). The valve (402) is resiliently restrained relative to a housing (418) with the valve and housing configured to accept a standard male luer lock having a luer tip (18) which penetrates the valve through the opening to extend within the housing and a luer locking flange of the luer lock extending about the housing. The valve (402) includes a disk shaped upper portion (404) covering the opening, a lower portion (406) spaced from the housing (418) and extending downward from the disk shaped portion into a passageway defined by the housing (418), and an annular skirt (408) to attach the septum to the housing. The connector (450) exhibits satisfactory leak pressure after multiple connections and disconnects to the luer lock fitting and long periods of indwell of the luer tip (18).

L'invention concerne un raccord sans aiguille (450) comportant une valve à membrane (402) préalablement fendue et réutilisable. Cette valve (402) est retenue de façon élastique par rapport à un logement (418). Cette valve et ce logement sont conçus pour recevoir un verrou Luer mâle standard pourvu d'une pointe Luer (18) qui pénètre dans la valve par l'ouverture, de façon à s'étendre dans le logement et une bride de verrouillage du type Luer du verrou Luer s'étendant autour du logement. Cette valve (402) comporte une partie supérieure (404) en forme de disque s'étendant vers le bas à partir de la partie en forme de disque pour pénétrer dans un passage défini par le logement (418). Cette valve (402) comporte également une jupe annulaire (408) servant à fixer la membrane au logement. Ce raccord (450) exerce une pression suffisante pour éviter les fuites après de multiples connexions au verrou Luer et déconnexions dudit verrou et de longues périodes de fixation de la pointe Luer (18).
