The present invention provides a mattress system (1) devised to achieve a function of automatic detection, mainly comprising: a mattress (2) having a simple structure a control unit (3) equipped with a unique user interface (31) for caregivers to simultaneously adjust three major functions, namely, therapy mode, therapy intensity and comfort level and a connection pipe (4) for supplying air and power. The system (1) is further provided with a built-in auto-setting function to sense the body characteristics of the patient (39) lying on the mattress (2) and determine an effective supporting pressure range for the patient (39). By detecting a pressure difference representing the body characteristics of the patient (39) lying on the mattress (2) and comparing with the data stored in a built-in database, the system (1) can always provide the patient (39) with not only a well-proved therapeutic effect through the auto-setting function, but also an adjustable comfort level on the patient’s request through the user interface (31).本發明提供設計成取得自動偵測功能的床墊系統(1),其包括:床墊(2),具有簡單結構;控制單元(3),係配備有單獨的使用者介面(31),用以允許照顧者能夠同時地調整三個主要功能,亦即,醫療模式、醫療強度及舒適程度;以及,連接管(4),用以供應氣體及動力。系統(1)又設有內建自動設定功能以感測躺在床墊(2)上的病患(39)的身體特徵以及決定用於病患(39)之有效支撐壓力範圍。藉由偵測代表躺在床墊(2)上的病患(39)的身體特徵之壓力差以及比較儲存在內建資料庫中的資料,系統(1)總是不僅經由自動設定功能而提供病患(39)良好證實的治療效果,也經由使用者介面(31)而依病患的請求來提供可調整的舒適程度。1‧‧‧床墊系統2‧‧‧床墊3‧‧‧控制單元4‧‧‧連接管
