Screw lift for hospital bed |
| abstract |
Each end of a patient litter of the bed is supported on an adjustable screw mechanism (12) having a support member (13) carried by spaced telescopic screw assemblies (27 and 28) mounted on a base member (11). The screw assemblies are driven by a single electric motor (36) through a train of gears having helical teeth oriented to offset inherent frictional forces of the screw assemblies. n Two coiled electrical cords (208, 209) extend between a control circuit 218 on the patient litter and the motor on the base and when the support member (13) is lowered they lie in the recess (200) in its underside. n A potentiometer 188 provides an electrical signal indicative of the relative vertical positions of the support member (13) and the base (11), and a manual drive arrangement is provided to permit the gear train to be manually driven. |
