ABSTRACT:
A walker for assisting physically challenged persons to move around. The walker comprises a frame with wheels mounted on it for traveling over a surface. Oxygen tank supports are mounted on the seat and are adapted to receive oxygen bottles therein. A counterbalance is mounted on the frame to counteract the weight of any oxygen bottles received in the tank supports and thereby maintain the stability and balance of the walker.
