A dialysis patient hemorrhagic detection warning device is adapted to cover an injection area, comprising a covering absorber, two detecting modules, a control module, and an alarm module. The covering absorber is used to absorb the leaked blood. The two detection modules are spaced apart from each other and disposed in the covering absorber. The control module is electrically connected to the two detection modules for discriminating whether the blood suction body absorbs blood. The alarm module is electrically connected to the control module. The alarm module issues an alarm when the covering absorber absorbs blood.一種洗腎病人溢血偵測警示裝置，適用於覆蓋於一注射區，包含一覆蓋吸收體、二偵測模組、一控制模組，及一警報模組。該覆蓋吸收體用以吸收漏出之血液。該二偵測模組間隔設置於該覆蓋吸收體。該控制模組與該二偵測模組電連接，以辨別該覆蓋吸收體是否吸收血液。該警報模組與該控制模組電連接。當該覆蓋吸收體吸收血液時，該警報模組發出警報。
