Title (EN) ANTI-DRAWBACK MEDICAL VALVE
(FR) CLAPET MEDICAL ANTI-RETOUR
Abstract: front page image
(EN)A gland member (28) within a medical valve (10) is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. To that end, the valve has a housing (14) forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen (36) that is a part of the flow path. The lumen has an opening (34) to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region (64) formed at least in part between the gland member itself and the post member. In addition, the variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume (i.e., when the valve is in the open mode) that is no less than its closed volume (i.e., when the valve is in the closed mode).
(FR)Un élément de garniture (28), tel qu'un presse-étoupe, à l'intérieur d'un clapet médical (10) est conçu pour présenter un volume interne pratiquement constant ou croissant simultanément au passage du clapet de sa fermeture à son ouverture. De ce fait, ce clapet possède un boîtier (14) constituant un intérieur contenant un trajet d'écoulement, ainsi qu'un élément fixe allongé (20) dans cet intérieur. Cet élément allongé comporte une lumière (36) faisant partie du trajet d'écoulement. Cette lumière possède une ouverture (34) vers l'intérieur du boîtier. Ce clapet comprend également un presse-étoupe entourant l'élément allongé afin de constituer une zone à volume variable (64) située au moins en partie entre ce presse-étoupe et l'élément allongé. De plus, cette zone à volume variable fait partie du trajet d'écoulement, tandis que le presse-étoupe bouche l'ouverture arrière de la lumière en mode de fermeture. La zone à volume variable possède un volume ouvert (à savoir, quand le clapet est en mode d'ouverture) non inférieur à son volume fermé (à savoir, quand le clapet se trouve en mode de fermeture).
