Filed:

Dec 6, 1983

Appl. No.:

6/558460

Inventors:

William H. Peck - Oldenburg IN

Assignee:

Hill-Rom Company, Inc. - Batesville IN

International Classification:

A61G 706

US Classification:

5 66

Abstract:

A wheeled hospital bed is removably connectible to a drive unit. The bed comprises a plurality of articulated frame sections, a plurality of driven shafts, a linkage interconnecting the driven shafts and the frame sections for articulating the latter in response to rotation of the driven shafts, and a first guide structure. The drive unit includes a plurality of motors and drive shafts, and a second guide structure arranged to interact with the first guide structure of the bed when the bed is merged with the drive unit in order to orient the bed and drive units such that the drive and driven shafts are mutually aligned. The drive and driven shafts include a self-coupling mechanism for establishing a drive connection therebetween when in a merged condition. The drive unit may be anchored to the floor, or may be supported solely by the bed. In the former case, the bed can be rotatable about a vertical axis relative to the drive unit while maintaining connection therewith.

Abstract:

A hydraulically operated hospital bed with dual hydraulic power systems for operation with or without electrical service. The bed has its head and thigh/leg elevation functions performed by hydraulic cylinders. A control circuit meters the introduction and removal of hydraulic fluid from these cylinders so an occupant of the bed is not subjected to any sudden movement. In case of an emergency requiring the bed occupant to be in a supine position (the need to perform CPR), the normal control circuit is bypassed by an emergency circuit that allows much faster than normal lowering of the head and thigh/leg portions of the bed.
