Detection Device for Bedding for Sleep Monitoring

摘要

A detection device, for placement under or on a mattress, configured for the movements of a person lying on the mattress, includes a sensing portion having an inflatable chamber intended to be positioned under the individual, an electronic unit arranged at a distance from the sensing portion and having a pressure sensor, intended to be positioned outside of the bedding, a transmitting portion interposed between the sensing portion and the electronic unit, including a channel establishing a fluid connection between the inflatable chamber and the sensor, the channel having a transverse dimension (T) that is much smaller than the width (L1) of the chamber.

主权项

1. A detection device, configured to be placed on or under a mattress so as to detect by ballistography at least movements, a heart rate, and a respiratory rate of an individual lying on the mattress, in particular in order to monitor sleep of the individual, comprising:
a sensing portion comprising at least one inflatable chamber intended to contain a fluid consisting of air, intended to be positioned under the individual, in particular under one of the pressure points of the recumbent individual namely the head, chest, or lower torso; an electronic unit arranged at a distance from the sensing portion, comprising at least one pressure sensor, intended to be positioned externally to the bedding, in particular close to the edge of the mattress or bedding; and a transmitting portion, interposed between the sensing portion and the electronic unit, comprising at least one channel, establishing a fluid connection between the inflatable chamber and the sensor so that the electronic unit receives the pressure changes induced by movements of the individual.
