Abstract
A wound dressing is selectively configurable for use in a pressure gradient wound therapy system and for use without a pressure gradient wound therapy system. The wound dressing can include a pressure distribution layer and a covering layer. The covering layer includes an indicia, the indicia denoting the optimal position in the covering layer to create an aperture to provide fluid communication between the pressure distribution layer and a source of non-atmospheric pressure.
Claims23
A one-piece wound dressing selectively configurable for use in a pressure gradient wound therapy system and for use without a pressure gradient wound therapy system, the wound dressing comprising:
- a wound contact layer;
- a plurality of absorbent layers;
- a pressure distribution layer;
- a covering layer comprising
- a first surface defining a wound dressing cavity containing the pressure distribution layer, the plurality of absorbent layers, and the wound contact layer, and
- a second surface;
- and
- an indica visible on the second surface of the covering layer denoting the optimal position in the covering layer to cut an aperture through the covering layer but not through the pressure distribution layer and the wound contact layer to provide fluid communication between the cavity and a source of non-atmospheric pressure,
- wherein the indicia is printed onto the second surface of the covering layer,
- wherein the covering layer, the pressure distribution layer, the plurality of absorbent layers, and the wound contact layer are formed as an integral item, and
- wherein in the configuration for use without a pressure gradient wound therapy system the covering layer is uninterrupted, and in the configuration for use with a pressure gradient wound therapy system the covering layer is interrupted by the aperture in the region of the indicia and the aperture does not extend into or through the pressure distribution layer and the wound contact layer.
A kit of parts including a selectively configurable one-piece wound dressing, the wound dressing being configurable for use in a pressure gradient wound therapy system and without a pressure gradient wound therapy system;
- the kit further comprising at least one of:
- a. packaging indicating that the wound dressing is selectively configurable for use in a pressure gradient wound therapy system and without a pressure gradient wound therapy system;
- b. instructions instructing a user as to how to configure the wound dressing for use in a pressure gradient wound therapy system and for use without a pressure gradient wound therapy system;
- c. a piercing tool configured to pierce a covering layer of the wound dressing to produce an aperture therein and thereby configure the wound dressing for use in a pressure gradient wound therapy system;
- d. a source of non-atmospheric pressure;
- e. a port for connection to the covering layer of the wound dressing to connect the wound dressing to the source of non-atmospheric pressure;
- and
- f. tubing for connection between the wound dressing and the source of non-atmospheric pressure;
- wherein the wound dressing comprises a wound contact layer, a plurality of absorbent layers, a pressure distribution layer, and the covering layer, the covering layer having a first surface facing the wound contact layer and defining a wound dressing cavity, and a second surface,
- wherein an indicia is visible on the second surface of the covering layer, the indica denoting a suitable position in the covering layer to cut an aperture through the covering layer but not through the pressure distribution layer and the wound contact layer to provide fluid communication between the wound dressing cavity and the source of non-atmospheric pressure,
- wherein the indicia is printed onto the covering layer and the wound dressing is a one-piece dressing in which the covering layer, the pressure distribution layer, the plurality of absorbent layers, and the wound contact layer are formed as an integral item, and
- wherein in the configuration for use without a pressure gradient wound therapy system the covering layer is uninterrupted, and in the configuration for use with a pressure gradient wound therapy system the covering layer is interrupted by the aperture in the region of the indicia and the aperture does not extend into or through the pressure distribution layer and the wound contact layer.
