Abstract
Abstract The stand provides wheeled support for ambulatory patients. Wide span legs, together with the low center of gravity, and a low horizontal push point are utilized. The patient grips the device through a toroidal ring grip. Intravenous bottles may be suspended from a pole supported above the grip. Large rubber casters are provided.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
105 words
An ambulatory patient support stand comprising: a wheeled base having a central axis and adapted to move over a supporting surface; an elongated vertical support member extending upwardly from said base on said axis; a push grip mounted to and radially spaced from said support member, said grip at least partially surrounding and being substantially concentric with said support member, said grip being vertically spaced from said base and being positioned intermediate the ends of said support member at approximately hip height for a person in erect position; and additional support means associated with and extending from said support member to removably retain external devices.
Claim 2
Dependent Claim
105 words
An ambulatory patient support stand comprising: a wheeled base having a central axis and adapted to move over a supporting surface; an elongated vertical support member extending upwardly from said base on said axis; a push grip mounted to and radially spaced from said support member, said grip at least partially surrounding and being substantially concentric with said support member, said grip being vertically spaced from said base and being positioned intermediate the ends of said support member at approximately hip height for a person in erect position; and additional support means associated with and extending from said support member to removably retain external devices.
Claim 3
Dependent Claim
16 words

Claim 6
Dependent Claim
32 words
The ambulatory patient support stand according to claim 1, wherein: the center of gravity of said stand is no more than 30 centimeters above the floor engaging portion of said wheeled base.
Claim 7
Dependent Claim
30 words
The ambulatory patient support stand according to claim 1, wherein: said base comprises three or more arms extending horizontally from a central hub and carrying wheels adjacent their outer ends.
