Description

  The present invention relates to a mattress device, and more particularly to a mattress device having detection of bed information.

An aging society will soon come to an end, and a shortage of medical and care workers cannot be avoided. People spend the longest sleeping time at work and rest time, often 6-8 hours.

An inner pressure detection module comprising a plurality of pressure detection units, electrically connected to the control module, provided in an intermediate region of the elastic module, for detecting an inner pressure parameter of the elastic module;
With
The plurality of pressure detection units include a conductive elastic body electrically connected to the control module, an insulating base, and a plurality of through holes interposed between the conductive elastic body and the insulating base. An insulating elastic body provided with a hole, and
At least one wire is laid on the surface of the insulating substrate facing the conductive elastic body so as to be exposed in the plurality of through holes,
When either the conductive elastic body or the insulating base material receives pressure toward the insulating elastic body, deformation toward the insulating elastic body occurs, and the deformation causes the conductive elastic body and the wire to Is electrically contacted through the through hole to detect the inner pressure parameter and the edge pressure parameter;
Wherein the control module, by referring both to the edge pressure parameter and the inner pressure parameter, and wherein the determining the immobility information of the mattress user, and wherein the, care system.   The care system according to claim 10, further comprising a care message recording module for recording various special care messages of a plurality of mattress users corresponding to the plurality of mattress devices.
