Abstract
The dressing system of the present invention provides, in one aspect, a composite dressing that allows a wound to be dressed in one easy step and redressed without disturbing the wound. The composite dressing comprises a contact component having a bottom side facing a wound, and a top side. A dressing component is releasably attached to the top side of the contact component such that the dressing component can be readily separated from the contact component if pulled relative to the contact component. The contact component can remain on the wound to prevent disturbance, and another composite dressing or dressing component can be applied to the contact component.
Claims59
A composite dressing applicable to a wound, comprising:
- (a) a contact component constructed of a continuous sheet that covers all portions of the wound over which the contact component is applied, said contact component being pliable and suitable for conforming contact with the surface of the wound such that when the contact component is placed on the wound, the entire surface of the wound beneath the contact component can be comformingly contacted by a bottom side of the contact component, an entire extent of the bottom surface of said contact component being substantially free from adhesives and thus non-adherent to the wound, said contact component also having a top side, and said contact component being constructed of a liquid permeable material to allow permeation of liquids therethrough with respect to the wound;
- and
- (b) a dressing component adapted for use in treating the wound, said dressing component and said contact component being releasably attached directly to each other such that they can be applied to the wound together in one step and such that, when the bottom side of said contact component is placed in substantially conforming contact with the wound, said contact component is entirely interposed between the surface of the wound underneath the contact component and said dressing component such that liquid can pass between the wound and the dressing component by permeation through said contact component, and said dressing component being releasably attached directly to said contact component such that said dressing component can be readily separated from said contact component when said contact component is in substantially conforming contact with the wound if said dressing component is pulled while said contact component is retained in place on the wound.
A method of treating a wound, comprising the steps of:
- (a) placing a first composite dressing having a first contact component and a first dressing component releasably attached directly to each other, on the wound by placing said first contact component in substantially surface conforming contact with the wound, said first contact component being flexible and liquid permeable and having a single, continuously non-adhesive bottom side suitable for surface conforming contact with the wound such that the entire surface of the wound beneath the first contact component is in contact with the bottom side of the first contact component, and said first dressing component adapted for use in treating the wound, said first dressing component releasably attached to said first contact component such that when said first contact component is placed in substantially surface conforming contact with the wound, said first contact component is entirely interposed between the surface of the wound beneath the contact component and said first dressing component such that liquid can pass between the wound and the dressing component by permeation through the contact component, and
- (b) removing said first dressing component from said first contact component whereby the first dressing component is separated from the first contact component when said first contact component is held in place over the wound and whereby said first contact component remains in place over the wound when said first contact component is not held in place over the wound.
A composite dressing applicable to a wound, comprising:
- (a) a flexible liquid permeable contact component having a single, continuously planar bottom side suitable for conforming contact with the surface of the wound such that when the bottom side is placed on the wound, the entire surface of the wound beneath the contact component can be conformingly contacted by the single bottom side of the contact component, said contact component also having a top side, and a contact perimeter, said contact component sufficiently liquid permeable to allow permeation of liquids through said contact component;
- and
- (b) a dressing component adapted for use in treating the wound, said dressing component and said contact component being releasably attached directly to each other such that they can be readily applied to the wound together in one step and such that when the bottom side of said contact component is placed in substantially conforming contact with the wound, said contact component is entirely interposed between the surface of the wound beneath the contact component and said dressing components such that liquid will pass between the wound and the dressing component by permeation through the contact component, said dressing component having an underside facing said top side and having a dressing perimeter, said dressing component attached to said contact component along at least one line of attachment such that said dressing component can be readily separated from said contact component approximately along said at least one line of attachment when said contact component is retained in place over the wound, said at least one line of attachment located such that said underside of said dressing component is readily accessible by at least one finger at least one point along said dressing perimeter.
A method of treating a wound, comprising the steps of:
- (a) placing a first composite dressing on the wound, said composite dressing comprising a first contact component contactable with the wound and a first dressing component releasably attached to said contact component;
- (b) removing said first dressing component and separating said first dressing component from said first contact component if said first contact component is held in place over the wound;
- and
- (c) placing a second composite dressing over the wound.

- (b) removing said first dressing component and separating said first dressing component from said first contact component if said first contact component is held in place over the wound;
- (c) separating a second dressing component of a second composite dressing from a second contact component of said second composite dressing;
- and
- (d) placing said separated second dressing component over said first contact component on said wound if said first contact component remains on the wound.
