Abstract
A patient transfer apparatus configured to traverse stairs includes a seat assembly, a rear leg pivotably coupled to the seat assembly, a track integrated with the rear leg, and a wheel coupled to a distal end portion of the rear leg. The seat assembly includes a frame with a seat portion. The rear leg is pivotable relative to the seat portion between a transport position and a stair traversing position. In the transport position the wheel is configured to contact a floor, and in the stair traversing position the track is configured to contact the stairs.
Claims17
A patient support apparatus configured to traverse stairs, comprising:
- a frame including a seat portion;
- a front leg coupled to the frame adjacent to a front side of the patient support apparatus;
- and
- a rear leg assembly spaced from the front leg, a proximal end of the rear leg assembly coupled to the frame adjacent to a rear side of the patient support apparatus and a distal end of the rear leg assembly pivotable relative to the seat portion between a transport position and a stair traversing position, the rear leg assembly being configured to support the patient support apparatus in the transport and stair traversing positions, the rear leg assembly including:
- a track configured to move relative to the frame to engage the stairs in the stair traversing position, and
- an extension member disposed at the proximal end of the rear leg assembly and configured to engage the stairs in the stair traversing position, the extension member extending from the track in the stair traversing position to increase an overall length of the rear leg assembly.
