Abstract: Tilt and dynamic terrain simulation systems are provided which are couplable to a wheelchair treadmill and are configured to dynamically tilt the wheelchair during use of the wheelchair treadmill for simulating an uneven terrain condition. In some embodiments, the dynamic tilt system includes one or more elevation devices placed under a platform for tilting the platform of the wheelchair treadmill from a horizontal plane to a non-horizontal plane, and each of the one or more elevation devices is controllably adjustable to extend an adjustable support that is mounted to the platform between a first height and a second height. In some embodiments, each of the one or more elevation devices includes one or more actuators for controllably adjusting a height of the adjustable support between the first height and the second height.

Abstract: Motorized assist systems are provided which are operable to assist in initiating and ceasing the rotation of rollers of wheelchair treadmill systems, and to provide resistance to user-applied forces to facilitate effective exercise. In some embodiments, the motorized assist system includes a driving motor mechanically connected to one or more rollers of a wheelchair treadmill and a sensor. The sensor is configured to detect a rotational force or a rotational velocity of the roller(s) of the wheelchair treadmill. The driving motor is configured to exert a driving force on the roller in response to a detected rotational force on the roller or in response to a detected rotational velocity of the roller.

Abstract: An exercise apparatus for users of wheelchairs which have a pair of side-by-side driving wheels includes a pair of rollers which support the wheelchair driving wheels. The rollers rotate independent of one another and each roller drives a separate flywheel which has a brake attached to it.

Abstract: A wheelchair exercise apparatus has a platform which will support a wheelchair. The platform has an elongate slot which the driving wheels of the wheelchair can drop slightly into. An elongate roller, having a central axis which is vertically below the center line of the slot, is movable between a lowered position where it is substantially below the upper surface of the platform and a raised position where it projects through the slot and extends partially above the upper surface of the platform. A locking system holds the wheelchair while the roller is being moved to its raised position and during the exercise period.

Abstract: A specimen collection system includes a swab having an elongate handle with an absorbent fabric tip releasably attached to one end. A container has an opening, located at one end that the swab can be inserted into. A stop, which covers a portion of the opening, has a channel which receives the handle when the swab is placed in the container. The channel is sized to allow the handle to be pulled through it out of the container, but not allow the tip to pass. Thus,. the tip is displaced from the swab and drops into the container when the handle is pulled out of the container.

Abstract: A swab for collecting specimens from patients has an elongate handle with an absorbent fabric swab tip at one end. The swab tip is releasably attached to the handle, and a sleeve, which slidably fits on the handle, can be pushed against the swab tip after a specimen has been collected to displace the swab tip from the handle and deposit it into a collection device.
