  • Patent number: 5385324
    Abstract: A quick clamping system has a clamping device for releasable clamping engagement in a clamping direction with a selected support member oriented vertically or horizontally. A support portion on the clamping device projects outwardly from the support member, and has three orthogonally oriented mounting bores projecting inwardly from spaced regions on the outer surface of the support portion such that one of the bores will be upright whatever the orientation of the support member. A carrier for supporting one or more objects, such as medical equipment, has a pin member for selective engagement in the upright mounting bore.
    Type: Grant

  • Patent number: 5344169
    Abstract: A mobile support stand for hospital equipment has a plurality of poles projecting upwardly from a wheeled base with IV hangers at the upper ends of the poles. The base has a span sufficient to provide the needed stability against tipping, with legs projecting outwardly from the base with wheels at their free ends for supporting and transporting the stand. At least one of the legs is retractable between a fully extended, operative position and a retracted, non-extended position. A securing mechanism allows the stand to be secured to existing mounting holes on a hospital bed with the retractable leg facing outward, and once the stand is secured to the bed the retractable leg is retracted out of the way so that the floor space taken up by the bed and attached stand is minimized.

  • Patent number: 5174533
    Abstract: An adjustable mounting assembly for mounting an instrument on a support member has a first clamping device for releasable clamping engagement with the support member and a second clamping device for securing to an instrument or piece of equipment, with a lockable, adjustable connection between the two clamping devices allowing adjustment about two perpendicular axes to allow the instrument orientation to be adjusted. In one version, an IV pole is secured at one end to the second clamping device, so that it can be oriented vertically or in any other selected orientation relative to a support member which may be vertical, horizontal, or in any other orientation. The pole can support other medical instruments such as IV pumps.
