PROBLEM TO BE SOLVED: To cancel the physical burden of patient when executing respiratory action monitoring. SOLUTION: In this respiration monitoring device, a sensor unit 1 equipped with a flux gate type magnetic detecting element 6 is attached onto the surface of the waiste of the patient, an AC current for excitation is supplied from an exciting current supply circuit 11 to an exciting coil 8, at the same time, ground magnetic signals detected by reception coils 9a and 9b are sent to a signal extracting part 12, and an electric signal corresponding to the change of ground magnetism received by the reception coils 9a and 9b with the passage of time is outputted as a respiratory waveform signal by this signal extracting part 12. Since the magnetic detecting element 6 is weakly attached and mounted just like being placed on the dullest waist part in the body, the mount of magnetic detecting element 6 can be prevented from giving pains to the patient. |
