Gastrostomy feeding ports are disclosed which remain positively sealed after repeated and extensive use. In one embodiment, a valve housing (20) defines an inner passageway (29) to provide fluid communication into a long term indwelling catheter and includes a rigid compression collar portion (21) which defines a valve member receiving cavity (22) within the inner passageway (29). A resilient valve member (10) is compressively inserted within the receiving cavity (22), and defines a valve slit (16) which is normally biased closed when the valve member is inserted in the cavity. A right angle feeding adapter (60) is received through slit (16) to provide for enteral feeding, medication or pressure relief. Additional embodiments are disclosed which provide for the direct conversion of an implanted PEG tube into a low profile feeding port, and which further provide for direct connection to a feeding tube adapter.
L'invention se rapporte à des orifices de gastrostomie pour admission de nourriture qui conservent une étanchéité absolue après usages répétés et importants. Selon un mode de réalisation, un corps (20) de soupape forme un passage interne (29) et crée ainsi une communication fluidique dans un cathéter fixé à demeure et comprend un collier de compression rigide (21) qui forme une cavité (22) logeant un élément de soupape, située dans le passage interne (29). L'élément de soupape élastique (10) est inséré par compression dans ladite cavité (22) et définit une fente de soupape (16) qui est normalement fermée par contrainte lorsque l'élément de soupape est inséré dans la cavité. Un adaptateur d'alimentation coudé (60) passe dans la fente (16) pour permettre l'alimentation, l'administration ou un relâchement de pression par voie entérale. Des modes de réalisation additionnels permettent la transformation directe d'un tube de gastrostomie endoscopique percutanée implanté en un port d'alimentation plat ainsi que le raccordement direct d'un adaptateur tubulaire d'alimentation.
