A kind of hospital bed weight-measuring device is using one hospital bed of what, and hospital bed has an idler wheel, and hospital bed weight-measuring device includes a pedestal, a bearing structure and a lifting mechanism. Pedestal includes a gravity sensor. Bearing structure is movably arranged on what pedestal, and bearing structure compresses what gravity sensor. To be lifted idler wheel, the side of lifting mechanism is movably connected what bearing structure lifting mechanism, lifting mechanism it is another then to support idler wheel. Hospital bed is lifted by lifting mechanism to measure the weight of sufferer on hospital bed.一種病床用測重裝置，係應用於一病床，病床具有一滾輪，病床用測重裝置包含一底座、一承載結構及一抬升機構。底座包含一重力感測器。承載結構可活動地設置於底座上，且承載結構抵壓於重力感測器。抬升機構用以抬升滾輪，抬升機構的一側可活動地連接於承載結構，抬升機構的另一則用以承托滾輪。藉由抬升機構抬升病床以量測病床上病患的體重。
