  • Patent number: 6518524
    Abstract: A multi-function stalk switch that incorporates a pushbutton switch, a first rotary switch and a second rotary switch onto the end of a stalk, wherein further switching functions may be executed by moving the entire stalk in either of two orthogonal planes. The stalk switch incorporates many design features that enable it to be assembled at low cost from a small number of parts. One such feature is the use of plastic-on-plastic detents to control positioning of the rotary switches so that they wipe across predetermined portions of a flexible printed circuit board. Another feature is the inclusion of a springloaded plunger detent riding in a concave centering mechanism that is operable to automatically return the stalk switch to its central (neutral) position after removal of external biasing forces. A further feature is the inclusion of magnets on the stalk switch and Hall effect sensors fixedly mounted nearby in order to sense movement of the magnets (and therefore the stalk) in two orthogonal planes.

  • Publication number: 20020161317
    Abstract: A control system for use with a vacuum bandage over a wound includes a vacuum pump, a waste canister operably coupled to the pump, and a fluid source. The canister is coupled to the bandage such that, when a vacuum is applied to the canister, the vacuum is applied to the bandage. The fluid source is coupled to the bandage to selectively introduce fluid into the wound.

  • Publication number: 20020161346
    Abstract: A wound dressing member is provided for use in a vacuum bandage connected to a vacuum source. The wound dressing member is also provided for use with a wound having a wound surface. The wound dressing member includes a wound facing surface adapted to be in contact with and generally conform to the wound surface and a plurality of discrete holes formed in the wound facing surface. The member further includes a port configured to communicate with the vacuum source and with each hole formed in the wound facing surface. The wound dressing member further includes a stand-off having interconnected portions coupled to the wound facing surface and configured to provide a space between the wound facing surface and the wound surface.

  • Publication number: 20020082567
    Abstract: A thin, flexible member is provided for use in a vacuum bandage connected to a vacuum source. The member is provided for use with a wound having a wound surface. The member includes a wound contacting surface adapted to be in contact with and generally conform to the wound surface. The member further includes a plurality of discrete holes formed in the wound contacting surface, a port configured to communicate with the vacuum source, and communicating means from the holes to the port. The member is formed from a generally non-porous material.
