  • Patent number: 7191992
    Abstract: A medical suspension system (10) includes a ceiling plate (30) configured for mounting to a support structure (16). The ceiling plate supports a device (12), such as a lighthead or video monitor, which is mounted to the ceiling plate via an articulated arm (50) and a spindle (40), which is centrally mounted to the ceiling plate. A second device (14) is mounted to the ceiling plate, not through the spindle (40), in the conventional manner, but via an adapter plate (62), which is mounted directly to the ceiling plate. This increases the number of devices which are readily carried by the support structure without extending the spindle length which conventionally occurs when additional hubs are added to the main spindle.

  • Patent number: 6203590
    Abstract: An evacuation system is provided for removing smoke generated during a surgical procedure performed in a surgical room. The evacuation system includes a pre-filter assembly and a replaceable filter cartridge module disposed in the surgical room to permit replacement of used filter cartridge modules with new filter cartridge modules by personnel within the surgical room. A vacuum generator is disposed outside of the surgical room and includes a vacuum pump for establishing an air flow through the replaceable filter cartridge module. The pre-filter assembly includes an elongate flexible suction hose that is adapted for manipulation into position adjacent the medical procedure. A mechanical connection mechanism enables pre-filter assemblies to be easily replaced between each surgical procedure. An accumulated filter usage circuit calculates a quantity of filter capacity available and generates a filter loading signal based on the available capacity.

  • Patent number: 6196649
    Abstract: A convertible medical appliance support apparatus includes a box-shaped hollow main body portion A suspended from overhead by a support apparatus B. A horizontal support table C extends forward from the front face of the vertical main body column to form a platform for supporting associated medical equipment. Multiple gas connections D are provided the main body portion together with a manual handle E near the bottom of the main column on a side of the column opposite from the support table to provide a convenient point to grip and move the body column into a desired position. Manually actuatable controls are provided at the handle, including brake release pushbuttons I and a motorized height adjustment toggle switch J. Multiple electrical connections F are included on the main body together with optional shelves G selectively attachable below the main platform.
