1. A sleep monitoring system comprising:
- a mattress sized for use in a bed frame comprising;
a first padding layer sized to fit to the bed frame; and
a sensing layer sized smaller than and positioned below the first padding layer, the sensing layer comprising a fluid bladder and a sensor positioned within the fluid bladder and in fluid communication with the fluid bladder, the sensor configured to detect waves propagated within the fluid bladder;
an inflation mechanism in fluid communication with the fluid; and
a controller located within the mattress and configured to;
receive signals from the sensor;
analyze the signals using pattern recognition to differentiate the signals based on frequency;
convert analysis results to vital signs of a subject on the mattress; and
output the vital signs of the subject to a control unit, wherein the fluid bladder defines at least one aperture extending from a first surface of the fluid bladder adjacent the first padding layer to a second surface of the fluid bladder opposite the first surface configured to provide a pass-through for fluids.

16. A mattress for determining a vital sign of a person lying thereon, the mattress comprising:
-
a first foam layer; a second foam layer; a fluid bladder between the first and second foam layers, the fluid bladder defining at least one aperture extending between a top side of the fluid bladder that the first foam layer rests on and a bottom side that rests on the second foam layer, the at least one aperture configured as a pass-through for fluid; and a sensor in fluid communication with the fluid bladder, the sensor configured to detect waves propagated within the fluid bladder; and a controller configured to; receive signals from the sensor; and analyze the signals using pattern recognition to differentiate the signals based on strength and frequency, with one strength and frequency associated with a heart rate, a second strength and frequency associated with a respiration rate, and a third strength and frequency associated with limb movement. - View Dependent Claims (17)
