A HOIST

摘要

A hoist for lifting a patient, the hoist having a housing with a winding mechanism (30) therein arranged to receive a first end of an elongate flexible tensile member (70) and to wind up that member from that end, wherein the hoist includes a magnetic member (92) positioned adjacent and fixed relative to the member and arranged to emit a signal, and a magnetic sensor (90) positioned adjacent the housing (20) and operable to sense a signal emitted by the magnetic member when the magnetic member is adjacent the magnetic sensor, the hoist being operable to cease winding the member in response to the magnetic sensor sensing that the magnetic member is adjacent thereto.
