A needle free medical connector includes a housing with a first port and a second port. The connector also includes a piston element defining a fluid passageway between the first and second ports. The piston element is movable between flow and non-flow positions. The piston element has a compressible section having a variable inner width that forms a part of the flow path through the connector. As the piston is compressed to the flow position, the compressible section self-expands in width thereby maintaining or increasing the volume of the fluid passageway through the connector. The compressible section has a configuration permitting the continuous flow of fluid through its entirety.
L'invention se rapporte à un connecteur médical comprenant un logement doté d'un premier port et d'un second port. Ce connecteur comprend également un élément de piston définissant un passage pour fluide entre le premier et le second port. L'élément de piston peut bouger entre des positions de débit et de non débit. Ledit élément de piston comporte une section compressible d'une largeur interne variable formant une partie du trajet de flux à travers le connecteur. Lorsque le piston est comprimé en position de flux, le section compressible s'étend dans le sens de sa largeur ce qui permet de maintenir ou d'augmenter le volume de fluide à travers le connecteur. La section compressible présente une configuration qui permet au flux de fluide de la traverser de par en par.
