摘要：
Disclosed is a patient lift system having a sling bar with an inductively charged integrated scale. The lift system comprises a lift apparatus, a lift strap connected at a first end to the lift apparatus, a sling bar connected to a second free hanging end of the lift strap, the sling bar having a scale with a tension load cell integrally disposed therein for measuring forces applied thereto and a power source electrically connected to the scale to provide power to the scale and load cell. An accelerometer is disposed within the sling bar to determine a tilt angle of a lift axis of the load cell relative to a vertical direction of gravitational force. Programming stored in a processor of the integrated scale calculates an accurate weight of an active load suspended from the sling bar, based on the determined tilt angle and the measured force on the load cell.
