Abstract: A patient support apparatus includes a base and a support frame. A lift system operates to lift and lower the support frame relative to the base. The lift system includes a first lift and a second lift. The first lift and the second lift are independently operable to place the support frame in one or more Trendelenburg positions. A plurality of load cells acts between the lifts and the support frame such that a load on the support frame is transmitted to the plurality of load cells to measure the load. The first lift includes a guided body arranged to move longitudinally relative to the base in response to operation of the second lift to move the support frame to the one or more Trendelenburg positions.

Abstract: A patient support apparatus includes a load cell, disposed between a base and a litter, that is configured to generate an output representative of a load acting on the patient support surface. The load cell is associated with a calibration reference symbol assigned to the load cell to define a calibration value for a parameter of the load cell. A user interface is configured to receive user input of a virtual symbol corresponding to the calibration reference symbol. A controller is configured to store a plurality of calibration reference symbols and a plurality of representative calibration values each associated with one of the plurality of calibration reference symbols, initiate a calibration procedure, determine a representative calibration value for each calibration reference symbol, calibrate the parameter of the load cell based on the representative calibration value determined based on the virtual symbol, and determine weight acting on the litter.
