Abstract

Un système de gestion de tuyau destiné à être utilisé pour distribuer un flux de gaz respiratoire aux voies respiratoires d'un patient comprend un boîtier central qui définit un espace intérieur à l'intérieur de celui-ci. Le système comprend en outre une partie de retenue supérieure qui s'étend radialement vers l'extérieur à partir d'une partie supérieure du boîtier central et une partie de retenue inférieure qui s'étend radialement vers l'extérieur à partir d'une partie inférieure du boîtier central. Un côté inférieur de la partie de retenue supérieure, un côté supérieur de la partie de retenue inférieure et une surface tournée vers l'extérieur du boîtier central définissent une rainure qui s'étend autour du boîtier central. La rainure est dimensionnée et configurée pour loger au moins une partie du tuyau à l'intérieur de celle-ci.
