  • Patent number: 5072906
    Abstract: In a hospital room, arms are pivoted on vertical axes that pass through the head and foot ends of a patient's bed. One of the arms carries a computer terminal at its free end. The other arm carries a power column or a portion of a power column at its free end. The arms are swingable around the end of the bed and to either side of the bed, whereupon the person attending the patient can use the instruments on the arms at the point of care for the patient.

  • Patent number: 5054141
    Abstract: A hospital bed is supported on a Y-shaped base to facilitate the introduction of a C-arm for imaging a patient's chest. Head guards are mounted on each side of the head end of the bed on linkages that permit the head guards to be swung toward the foot end of the bed to improve the positioning of the C-arm over the head end of the bed. The head panel has pivotable longitudinal edges to further improve the positioning of the C-arm over the head end of the bed. Pivotable longitudinal edges of the head and leg panels permit head and foot guards to be moved laterally inwardly to narrow the bed for transporting a patient.

  • Patent number: 4882566
    Abstract: A safety control system for an electrically operated hospital bed utilizes a wireless disconnect signal from an above mounted safety light to an outlet below which supplies electrical power to the bed, thereby to interrupt power to the outlet upon the detection of physical contact with the safety light, as perhaps caused by an IV pole raising with the bed. In a preferred embodiment, a two-way transmission path is utilized to verify no blockage of the line of sight transmission path between the outlet and the light, with power to the outlet being disconnected upon contact with the light or blockage of the line of sight path.

  • Patent number: 4811435
    Abstract: A hospital bed having a pivoted headboard that functions as a work center. The headboard can be swung to either side of the bed and locked there as well as its normal position at the head of the bed.

  • Patent number: 4715295
    Abstract: An improved table is disclosed which permits easy access to additional useable horizontal surface and which permits easy raising and lowering. The table, which in its preferred embodiment, is a hospital overbed table, is equipped with upper and lower horizontal tray surfaces. The surfaces are movable with respect to each other and may be positioned to expose the top surface alone or the upper and lower surfaces. The upper and lower surfaces may also be moved in unison to expose storage cavities in a base supporting the tray surfaces. A gas spring mechanism permits easy adjustment of the vertical positioning of the overbed table and provides a mechanism for securely locking the overbed table in place when in use.

  • Patent number: 4592104
    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.

  • Patent number: 4559656
    Abstract: A bed uniformly distributes the weight of a bed-ridden patient to minimize the occurrence of bedsores. The bed comprises a frame and a plurality of support assemblies mounted on the frame. Each support assembly comprises a plurality of elongate support slats extending transversely of the fore-aft direction, and a pair of transversely spaced lever modules carrying opposite ends of the slats. Each lever module comprises a plurality of levers which are so mounted as to be swung in response to the downward action of heavier portions of the patient, whereupon opposite ends of the levers swing upwardly to transfer some of that weight to the lighter portions of the patient's body. The levers disposed on one side of the bed are rotatable relative to the corresponding levers on the opposite side of the bed, whereby the support slats may assume positions inclined relative to horizontal and thereby maintain a greater degree of contact with the patient.
