Outline of Final Research Achievements

A nutrition is poured into the stomach of a patient who has a difficulty in swallowing etc., using the nasogastric tube made of resin. When the tube is inserted from the hole of a nose to the stomach, it may be inserted into lungs by mistake. It will become a fatal situation if nutrition is poured in with incorrect insertion. In this paper, the inspection technique of the position of the tip tube inside the human body was examined by detecting the alternating magnetic field excited from ten positions of outside on the human body using the magnetic sensor at the tip of the tube. It is shown that the maximum error of positioning is less than 10mm, then the proposed technique can be applicable in an actual hospital.
