Abstract
A movable base support for a medical examination chair permits movement of the examination chair to provide a space allowing a wheelchair to be positioned adjacent medical instruments. The base support for the examination includes a power unit pivotally mounted to a rear of the platform and biased towards the floor. The bias force ensures that the power unit maintains contact with uneven floor surfaces. A guide system assembly limits the range of movement, and allows the examination chair to be returned to a precise original location adjacent to medical instruments.
Claims12
A movable base for supporting a patient examination chair comprising:
- a first member for supporting an examination chair including a platform and a plurality of first member wheels supporting said platform;
- a guide track carried by said first member, said guide track being generally U-shaped with two laterally spaced guide flanges, said guide flanges extending downwardly with respect to said floor;
- and
- a floor track adapted to be rigidly mounted to a floor, said guide track being slidingly received on said floor track to control movement of said first member, said floor track being generally U-shaped with two laterally spaced floor flanges, said floor flanges extending upwardly with respect to said floor, one of said floor and guide flanges being received laterally outwardly of the other.
1 more element
A method for providing space for a wheelchair adjacent fixed medical instruments comprising the steps of:
- (1) locating a pre-determined first location for a patient examination chair, said first location being adjacent to fixed medical instruments;
- (2) locating a pre-determined second location for said patient examination chair, said second location being spaced from said first location in a direction away from said fixed medical instruments a distance sufficient to allow for placement of a wheelchair between said fixed medical instruments and said patient examination chair;
- (3) providing said patient examination chair with a movement means, for moving said patient examination chair, said movement means further being adapted to lock said patient examination chair at said first or second location;
- (4) providing said patient examination chair with a guiding means, for guided movement of said patient examination chair between said first location and said second location;
- (5) providing said guiding means with an indicator at said first location to assist in returning said patient examination chair to said first location;
- (6) selectively moving said patient examination chair from said first location to said second location;
- (7) moving said wheelchair to a treatment location adjacent said first location when said patient examination chair is at said second location;
- (8) treating a patient in said wheelchair with said fixed medical instruments;
- (9) moving said wheelchair from said treatment location;
- and
- (10) selectively moving said patient examination chair from said second location to said first location, the movement ceasing at said indicator provided at said first location.
8 more elements
A medical treatment assembly comprising:
- medical treatment instruments mounted at a first location;
- an examination chair, movable between a treatment position adjacent to said first location, and a non-treatment position removed from said first location by a distance sufficient such that said medical chair may be moved to said non-treatment position to provide access for a wheelchair to be placed in the position previously occupied by said examination chair in said treatment position;
- a floor track fixed to a floor;
- and
- a guide track movable with said examination chair, said guide track being slidably received on said floor track, such that said guide track and said floor track guide movement of said examination chair between said treatment and non-treatment positions, and assure that said examination chair is properly positioned relative to said first location when said chair is in said treatment position, said floor track being generally U-shaped with two floor flanges laterally spaced and extending vertically upwardly from said floor, and said guide track being generally U-shaped with two guide flanges laterally spaced and extending downwardly towards said floor, one of said floor and guide flanges being received laterally outwardly of the other to provide said slidable support.
