The present invention is a low profile jejunal adapter (10) for a low profile gastrostomy tube (12). Once property attached, the jejunal adapter (10) converts the low profile gastrostomy tube (12) into a gastrojejunostomy tube. Specifically, the jejunal adapter (10) includes a feeding tube (46) which is positioned within the jejunum of a patient and venting lumen (48) which provides for simultaneous venting of gases collected in the patient's stomach while fluid is being fed to the jejunum through the feeding tube (46). In a preferred embodiment, the length of the feeding tube is adjustable to accommodate various patients. In an alternative embodiment, the length of the feeding tube (46) is fixed to reduce the manufacturing costs of this device. The jejunal adapter (10) also includes a cap retention mechanism (62) for securing the cap (26) of the gastrostomy tube (12) and a latch mechanism (156) adapted to secure the jejunal adapter (10) to the gastrostomy tube (12).

La présente invention concerne un adaptateur jéjunal compact (10) pour un tube de gastrotomie plat (12). Une fois fixé de manière appropriée, l'adaptateur jéjunal (10) transforme le tube de gastrotomie plat (12) en tube de gastro-jéjunostomie. Plus précisément, l'adaptateur jéjunal (10) comporte un tube d'alimentation (46) placé au sein du jéjunum d'un patient et une lumière d'aération (48) permettant l'évacuation des gaz accumulés dans l'estomac du patient pendant l'alimentation en fluide du jéjunum à travers le tube d'alimentation (46). Dans un mode de réalisation préféré, la longueur du tube d'alimentation est réglable pour s'adapter à différents patients. Dans une autre variante, la longueur du tube d'alimentation (46) est fixe afin de réduire les coûts de fabrication dudit dispositif. L'adaptateur jéjunal (10) comporte également un mécanisme de retenue de coiffe (62) pour fixer la coiffe (26) du tube de gastrotomie (12) et un mécanisme de verrouillage destiné à solidariser l'adaptateur jéjunal (10) au tube de gastrotomie (12).
