Multi-lumen enteral feeding and medicating device

摘要

A multi-lumen enteral feeding and medicating device having a gastric tube adapted to be introduced into the interior of a patient's stomach through a stoma. The gastric tube has a balloon to engage and seal against the interior wall of the stomach around the stoma and a locking ring to engage the skin of the patient surrounding the exterior opening of the stoma. A jejunal tube is slidably engaged in the gastric tube for relative longitudinal sliding displacement so that the distal end of the jejunal tube may be threaded through the stomach into the jejunum for introduction of a fluent material through ports adjacent the distal end of the jejunal lumen. A fluid lumen is provided in the gastric tube for applying positive and negative pressure to the interior of the balloon to extend and retract the same and an inlet attachment is provided for accessing the gastric lumen for introducing fluent material into the stomach through the gastric lumen. The jejunal tube passes through the gastric lumen and out through the inlet attachment. A sealing plug is provided to seal the inlet to the gastric lumen at the point where the jejunal tube exits the gastric lumen. The sealing plug operates to anchor the jejunal tube within the gastric lumen at the desired location which positions the distal end of the jejunal tube within the jejunum.
