Beschreibung
Zusammenfassung:	A respiration-synchronous type gas supplying device in the form of a device having a performance for preventing erroneous recognition caused by variations in patient's respiration phase or by disturbance such as vibration of the supplying device, wind or the like, patient's indisposition due to erroneous oxygen supply, and waste of oxygen supply, the supplying device being characterized by comprising a means for recognizing an inhale phase start section and an exhale phase start section, the recognition means effecting automatic valve opening/closing control such that during a period from the time the inhale phase start section is recognized until the exhale phase start section is recognized and during a period from the time the inhale phase start section is recognized until a predetermined time passes, recognition of the next inhale phase start section is not made.
