A multilumen discharge assembly (10) for delivering mixed biological adhesives is provided, which comprises a base portion (14) including a flow path (22) to provide mixed biological adhesives therethrough, and an elongate cylinder (12) defining a plurality of axially extending flow channels (18) connected to an outlet port (36), where the elongate cylinder (12) is rotatably mounted relative to the base portion (14) to permit sequential alignment of said flow path (22) with a respective one of said plurality of flow channels upon rotation thereof. The discharge assembly further includes a declogging mechanism disposed adjacent the elongate cylinder (12) and including at least one scraping member (38) for scraping a portion of said outlet port (36) to provide a substantially clear opening for delivering mixed biological adhesives. The declogging mechanism may include a declogging pro-jection (34) to eject clogging material from the opening in said outlet port (36) and/or at least one scraper (38) to remove clogging material from peripheral portions around the outlet port (36) upon rotation of the elongate cylinder (12).

L'invention concerne un ensemble applicateur (10) à plusieurs lumières destiné à l'application d'un mélange d'adhésifs biologiques. Ledit ensemble comprend une base (14) comportant un chemin (22) d'écoulement destiné au cheminement du mélange d'adhésifs biologiques, et un cylindre (12) allongé définissant une pluralité de canaux (18) d'écoulement d'extension axiale reliés à un orifice (36) de sortie, ledit cylindre (12) allongé étant monté rotatif par rapport à la base (14) pour permettre l'alignement séquentiel dudit chemin (22) d'écoulement et de l'un des canaux d'écoulement lors de la rotation dudit cylindre. L'ensemble applicateur comprend également un mécanisme de désobstruction disposé adjacent au cylindre (12) allongé, lequel mécanisme comporte au moins un élément (38) de grattage destiné à gratter une partie de l'orifice (36) de sortie de manière à maintenir une ouverture sensiblement nette en vue de l'application du mélange d'adhésifs biologiques. Ledit mécanisme de désobstruction peut comporter un élément saillant de désobstruction (34) destiné à éjecter les matières obstruantes par l'ouverture dudit orifice (36) de sortie et/ou au moins un racloir (38) destiné à éliminer les matières obstruantes des parties périphériques de l'orifice (36) de sortie lors de la rotation du cylindre (12) allongé.
