PROBLEM TO BE SOLVED: To provide a mattress device capable of being warmed and accurately extracting biological information.SOLUTION: The mattress device comprises a mattress body 20, a warming means 30, a pressure detecting means 31, a temperature detecting means 32, and an arithmetic operation means 33. Since the arithmetic operation means 33 extracts the biological information from pressure signals based on temperature signals, the biological information can be accurately extracted even if the warming means 30 is on.COPYRIGHT: (C)2009,JPO&INPIT【課題】加温可能であり、かつ生体情報を精度高く抽出できるマットレス装置を提供すること。【解決手段】マットレス装置に、マットレス本体20と加温手段30と圧力検知手段31と温度検知手段32と演算手段33とを設ける。演算手段33によって、温度信号を基に圧力信号から生体情報を抽出することで、加温手段30がオン状態にある場合にも、生体情報を精度高く抽出できる。【選択図】図1
