Device for measuring compliance with oxygen therapy using a three-dimensional accelerometer

摘要

The invention relates to a device for measuring patient compliance with oxygen therapy, including a casing (4) comprising means for detection of the oxygen therapy in order to evaluate data relating to the treatment; and means for measuring a state of physical activity of the patient. Preferably, the means for measuring a state of physical activity of the patient comprise at least one sensor which senses movement of the patient's body and outputs data relating to the spatial displacement of the patient's body, for example a three-dimensional accelerometer (28); and processing means (40, 42) for processing the body displacement data in order to supply a state of physical activity of the patient chosen from a sleeping state, a resting state and an active state.
