A nursing bed capable of sitting posture, comprising a labor-saving transmission device disposed inside the bed frame body； a bed plate device disposed above the labor-saving transmission device； and a device between the labor-saving transmission device and the bed plate device a one-prong device； the labor-saving transmission device drives a transmission mechanism with a power output shaft, and then the first and second push-up rods are respectively driven by the transmission mechanism, and the first push-up rod can drive a back movable frame to an inclined angle. The second push rod can synchronously drive a leg movable frame to fall downward； the invention uses the transmission device formed by the principle of lever operation on the nursing bed, which has labor-saving characteristics and convenient operation, and thus can be used by the patient. Sitting in the bed directly on the bed to achieve the effect of self-care.一種可呈坐姿便溺的護理床，包含一設於床架體之內的一省力型傳動裝置；一設於省力型傳動裝置上方的一床板裝置；一設於省力型傳動裝置及床板裝置之間的一便溺裝置；省力型傳動裝置以一動力輸出軸來帶動一傳動機構，再由傳動機構分別驅動第一、二推升桿，第一推升桿可以帶動一背部活動架呈一傾斜角度，第二推升桿可以同步帶動一腿部活動架向下沉降；本發明係將槓桿操作原理所構成的傳動裝置使用在護理床上，其具有省力特性及操作上的方便性，進而可供病人以坐姿直接在病床上進行大小便的動作，達到病人自理之功效。
