ABSTRACT:
A method and apparatus for placing a nasogastric tube into a patient by inserting and releasably anchoring a pH detector in the bore of the tube adjacent the distal end. The detector is connected through the proximal end of the tube to a pH monitor. The tube and detector are inserted into the patient while monitoring the measured pH of the detector for determining the placement of the tube. After placing the tube, the detector is released from the bore of the tube and removed from the nasogastric tube while leaving the tube in the patient. The detector is releasably anchored by inflating a balloon connected to the detector.
