A kind of sufferer that perceives includes from the hospital bed that bed acts: a bedstead, a detecting mould group, a processing mould group and an alarm mould group. The bedstead is at least one from bed side. The detecting mould group includes several detecting units for being separately positioned on the bedstead, and each detecting unit all can issue an alerting when sufferer limbs are by being somebody's turn to do from bed side. The processing mould group, which can receive and handle the alerting that the grade detecting units are issued, can issue one from bed signal when the processing mould group receives multiple alertings simultaneously. The alarm mould group signal connects the processing mould group and can be driven by this from bed signal and issue an alert message, therefore the utility model can notify that nursing staff comes to watch over the sick early, other than it can be reduced medical tangle, can also mitigate the burden that nursing staff goes on patrol ward.一種可感知病患離床動作的病床，包含：一床架、一偵測模組、一處理模組，以及一警報模組。該床架具有至少一離床側邊。該偵測模組包括數個分別設置在該床架的偵測單元，每一偵測單元都可在病患肢體通過該離床側邊時發出一警示訊號。該處理模組能接收與處理該等偵測單元所發出的警示訊號，該處理模組同時接收到多個警示訊號時，會發出一離床訊號。該警報模組訊號連接該處理模組且會被該離床訊號驅動而發出一警報訊息，因此本新型能及早通知護理人員前來照料病人，除了能減少醫療糾紛外，也可以減輕護理人員巡邏病房的負擔。
