The base board is provided with a through hole, the feces hopper and the feces hopper housing penetrate the through hole, the feces hopper is movably connected to the base board, a feces sensor is disposed between the feces hopper and the feces hopper housing, and the feces hopper is provided with a flushing hole. The
bed pan further comprises a clinging mechanism, the clinging mechanism is used for making the periphery of the top of the feces hopper cling to the human butt when the
human body is sideways, and the clinging mechanism comprises a sideway sensor used for sensing whether the
human body is sideways or not. By adopting the bed pan, a patient can excrete when he is sideways, feces can be directly excreted in the feces hopper, feces can be prevented from excreting outside caused by displacement of the bed pan, the feces can be smoothly excreted, a patient can have a clean and comfortable bedridden environment.
