Headband that contracts in synchrony with inspiration during sleep

Abstract

The present invention discloses a head piece, such as a headband or helmet, that fits around the cranium and includes one or more contractile elements which contract in synchrony with inspiration during sleep. The head piece is connected to a breath sensor which signals the timing of inspiration and software which incorporates the generated timing signals from the breath sensor to control the timing and release of the contraction of the head piece to coordinate with the user's breath. The breath sensor may comprise a variety of mechanisms such as a flow valve in the tubing of a CPAP or other type of automated breathing machine, an anemometer such as a hot wire anemometer to directly detect airflow in front of the nose or mouth, acoustic sensors to record breathing sounds, or a radar detector that monitors chest or abdomen movements from above the bed. In the illustrated embodiments, the breath sensor is a chest band that signals inspiration by recording an increase in tension produced by expansion of the chest. Coupling expansion of the chest with compression of the cranium is advantageous, because these movements occur simultaneously and because the expansion of the chest occurs with much greater force than the compression of the cranium, therefore the natural expansion of the chest can power the compressive forces which are desirably applied to the cranium. The chest band and head piece can be coupled to provide such a self powered head pumping mechanism by an electrical connection or a tube that permits flow of a liquid or air between the two areas.
