    摘要: A manually-powered wheelchair that includes one or more features that enhance the overall maneuverability and stability of the wheelchair, such as centrally mounted drive-wheels and an anti-tip system. Other embodiments may include at least one of an adjustable anti-tip system that may be selectively located to several locations on the frame; a positive stop device attached to either the mounting bracket, frame, or the anti-tip system for limiting movement of the anti-tip system and the frame relative to each other; a resistance device attached to the frame and the anti-tip system for increasing resistance between the frame and the anti-tip system when the user leans backwards in the wheelchair; a wheel lock system engaging at least one of the drive wheels below the wheel's axis of rotation; and a tilt prevention device for selectively preventing any rotation of the wheelchair frame and anti-tip system relative to each other.

    摘要: A method of filling a portable tank with compressed oxygen-enriched gas includes the steps of providing a coupling such that when a portable tank is connected with the coupling oxygen-enriched gas can flow through the coupling into the portable tank; directing oxygen-enriched gas from an oxygen concentrator to a compressor; compressing the oxygen-enriched gas in the compressor; directing compressed oxygen-enriched gas from the compressor to a reservoir; storing the compressed oxygen-enriched gas in the reservoir; and thereafter directing stored oxygen-enriched gas from the reservoir to the coupling to enable filling of a portable tank with compressed oxygen-enriched gas from the reservoir.

    摘要: An adjustable bed includes a universal, or interchangeable, bed end that can be used at either end of the bed and that can be connected with a motor drive assembly. The bed end may include a manual crank that is removably attached to the bed end. The bed end may include an elevating mechanism that includes a cross-beam or similar structure for transmitting motive force between fixed and movable portions of the bed end. The bed end may also include a new slip nut for transmitting motive force from a lead screw. The bed may further include a reversible corner plate for allowing the bed end to be used facing in either direction. The bed end may also include a plastic cover that is washable and scratch resistant.
