Device for sleep diagnosis
First Claim
1. A sleep diagnostic and screening device comprisinga data acquisition unit, the data acquisition unit comprising:
- a power source, the power source for providing power to the data acquisition unit and for providing power to sensors connected to the data acquisition unit;
at least three input channels having at least two input connectors and a point of connection for a nasal cannula; and
at least one electronic component for collecting and storing data;
a respiratory belt having two ends comprising fasteners at each end adapted to attaching the belt around a subject, and an electronic connector for electronically connecting the data acquisition unit directly to the respiratory belt without the use of a length of wire, the electronic connector being oriented on the respiratory belt in such a way that the data acquisition unit can be connected to the respiratory belt in only one orientation;
a nasal cannula for measuring airflow; and
a pulse oximeter comprising an input connector for electronically connecting the data acquisition unit to the pulse oximeter.

Abstract
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.
