The present invention is a sealing piece that can releaseably form a seal around the outside surface of a naso-gastric tube, the sealing piece being adapted to be sealingly supported from a surface having a hole at least the diameter of a distal end of a naso-gastric tube. In a specific embodiment, an elastomer sealing piece has a hole about the diameter of or just smaller than the diameter of a naso-gastric tube or other feeding tube and the sealing piece has a continuous slit from the hole to an outside edge. The slit is adapted to permit the sealing piece to be pulled apart at least enough so that the tube part of a naso-gastric tube may be sealingly located in the hole or removed from it. In operation, the invention would permit the patient having an appropriately inserted naso-gastric tube to threat the distal end of the naso-gastric tube to an access location external to a pressurized ventilation environment, i.e., a ventilation or anesthesia mask and associated gas tubing and access ports. |
