Abstract
A breathing monitor for detecting SIDS in infants caused by apnea or the like includes an enclosure which is applied to a baby's torso with a strap. The enclosure is supported by and isolated from the baby's torso in its entirety by a fluid filled bladder coupler such that there is no direct contact between the enclosure and the baby's torso. A detector including a piezoelectric element is connected to the opposite side of the fluid coupler and a battery powered electronic circuit contained within the enclosure flashes an LED as the baby breathes and sounds an alarm should the baby fail to exhale for a predetermined time period. An adjustable strap connector for the strap provides visual indication of the strap being correctly applied and a limited range of permissible motion between the strap and enclosure as the baby breathes.
