Abstract: A packaged intermittent urinary catheter comprising a single use catheter, a packaging surrounding the catheter, and a fluid reservoir holding a lubricant which, upon rupturing the fluid reservoir, is transferred into the packaging to immerse at least a portion of the catheter in the lubricant to prepare the catheter for use, wherein the lubricant comprises an antimicrobial medium. The invention further provides a method of using a packaged intermittent urinary catheter, and the use of a medium comprising at least one species independently chosen from: hypochlorous acid, at least one hypochlorite salt, chlorine dioxide, at least one chlorhexidine salt, and combinations thereof, as an antimicrobial medium for a single use intermittent urinary catheter.

Abstract: The invention provides a reusable urinary catheter kit comprising a container comprising: a urinary catheter; and a medium comprising at least one species independently chosen from: hypochlorous acid, at least one hypochlorite salt, chlorine dioxide, and combinations thereof. The invention further provides a method of sterilising and/or lubricating a reusable urinary catheter using at least one species independently chosen from: hypochlorous acid, at least one hypochlorite salt, chlorine dioxide, and combinations thereof.

Abstract: A variable force keyboard may include a keyboard box, a plurality of keys operatively connected to the keyboard box for movement relative to the keyboard box, and, for each of the plurality of keys, a resistive force may be provided that opposes movement of the corresponding one of the plurality of keys. The resistive force may be applied by key springs or other like structures acting on the keys, or the keys may be resilient structures such as cantilever springs that resist displacement. The variable force keyboard is configured to model a graphical, mathematical or physical relationship by varying the resistive force on each of the plurality of keys to correspond to values of the graphical, mathematical or physical relationship modeled by the variable force keyboard.
