Abstract: This invention relates in general to a dual-function bed used as a chair equipped with a patient toilet. The bed is designed to be selectively used as a chair by controlling the folding angle of it with the operation of a reduction motor. Moreover, as attached equipment, the toilet having the capabilities of cleaning itself and discharging excrement, gives great convenience to a patient. Subsequently, this invention allows a disabled and non-ambulatory patient to relieve oneself and rest by simply operating a control unit without nurse.
