Patent attributes
The present invention is related to a compact, portable, user-friendly sleep disorder diagnosis and screening device. The present invention is further related to a single-ended respiratory inductance plethysmography belt used to monitor certain parameters of a subject's respiration while at the same time serving to position and mechanically stabilize a compact data acquisition system about a subject's thorax or abdomen. In one application of the present invention to screen for sleep disorders, the single-ended respiratory inductance plethysmography belt is worn by the subject and a compact data acquisition unit is attached to the belt to which appropriate additional sensors and components such as a pulse oximeter and a nasal cannula are connected. Data is then collected using the belt, compact data acquisition unit, and sensors and is used to determine whether the subject has, or is at risk of having, a sleep disorder.
