Air mattress controller

Abstract

The pressure of air to be fed into each of air cells ( 51 - 54 ) of an air mattress body ( 50 ) is selected by an air pressure selector ( 12 ) based on body information entered through an entry control panel ( 20 ), thereby adjusting the mattress hardness. Meanwhile, an operating mode selector switch ( 17 ) selects one of a rest mode and a pressure switch mode as an operating mode of the air mattress body ( 50 ).

1 . An air mattress controller for feeding air into a plurality of air cells forming an air mattress body, the air mattress controller comprising:
 an entry controller for entering body information indicating body conditions of a user;   an air pressure selector for selecting the pressure of air to be fed into each of the air cells, based on the body information entered through the entry controller; and   an air feeder for feeding air into each of the air cells at the air pressure selected by the air pressure selector.   
   
   
       2 . The air mattress controller of  claim 1  further comprising
 a calculator for calculating a risk of bed sores indicating whether or not the user tends to develop bed sores, based on the body information entered through the entry controller,   wherein the air pressure selector selects the pressure of air to be fed into each of the air cells, based on the risk of bed sores calculated by the calculator, thereby adjusting the hardness of the air mattress body.   
   
   
       3 . The air mattress controller of  claim 1  further comprising
 an operating mode selector switch for selectively switching between a rest mode where air is fed into the air cells at generally a same pressure so that a surface of the air mattress body becomes generally flat, and a pressure switch mode where while air is fed into the plurality of air cells at different pressures so that the surface of the air mattress body is formed with projections and depressions, the pressures of air to be fed into the plurality of air cells are changed once every predetermined time interval to periodically change locations of surface regions of the air mattress body which are formed with the projections and the depressions,   wherein the operating mode selector switch selects one of the rest mode and the pressure switch mode based on the body information.   
   
   
       4 . The air mattress controller of  claim 1 , wherein
 at least one of the plurality of air cells forms a mattress thickness adjustment layer for adjusting the thickness of the air mattress body,   the body information entered through the entry controller include rolling-over ability information indicating whether or not the user can roll over by himself or herself,   when a determination is made based on the rolling-over ability information that the user can roll over, the air pressure selector selects a low air pressure as the pressure of air to be fed into the air cell forming the mattress thickness adjustment layer, and when a determination is made that the user cannot roll over, the air pressure selector selects a high air pressure as the pressure of air to be fed into the air cell forming the mattress thickness adjustment layer.   
   
   
       5 . The air mattress controller of  claim 1  further comprising
 a dehumidifier for blowing air to a surface of the air mattress body or into the air mattress body to dehumidify the surface or interior of the air mattress body,   wherein the body information entered through the entry controller include sweating information indicating an amount of sweat produced by the user, and   the dehumidifier adjusts an amount of the air to be blown based on the sweating information.
