Mainly system provides a kind of hospital bed bedside rails alarming device for this creation,It includes have: a bedstead group,Its two sides is respectively equipped with two bedside rails,Respectively the bedside rails system is set in enclosing with preset direction rotation and non-encloses the state transformation set； One alarming device,It has at least inductive module set on the what one bedside rails,Can what sense the bedside rails generate rotation predetermined angle actuation Hou,Transmission signal to one first warning group,It is set to generate alerting,The inductive module have the fixed what bedside rails on one of ball switch,And can with the bedside rails synchronous rotary actuation,When the bedside rails rotate predetermined angle Hou,The ball switch is then set to touch contact,And it generates a signal and is transmitted to the warning mould group； By above-mentioned component,In conjunction with the bedside rails to rotate actuation folding,Bedside rails spinning movement Hou is detected,The automatic signal that issues to warning group,The distal end nursing station of fit applications Radio Transmission Technology transmission signal,The setting of circuit can be reduced,Safety is promoted,Simultaneously overall structure it is simple,Manufacturing cost is low,It is upper easy using upper and operation,It can widely and in large quantities use what medical treatment institutes person.本創作主要係提供一種醫療用床之床欄警示裝置，其包含有：一床架組，其兩側分別設有二床欄，各該床欄係以預設方向旋轉而呈圍設及非圍設之狀態變換；一警示裝置，其具有設於其一該床欄上之至少一感應模組，可於感應到該床欄產生旋轉預設角度作動後，傳輸訊號至一第一警示組，使其產生警示訊號，該感應模組具有固設於該床欄上之一滾珠開關，並可與該床欄同步旋轉作動，當該床欄旋轉預設角度後，則使該滾珠開關觸動接點，而產生一訊號傳輸至該警示模組；藉由上述構件，結合以旋轉作動收折式之床欄，偵測床欄旋轉動作後，自動發出訊號至警示組，配合應用無線傳輸技術傳輸訊號之遠端護理站，可減少電路之設置，提升安全性，同時整體結構簡單、製造成本低，使用上及操作上簡便，可廣泛地且大量地使用於醫療院所者。
