Abstract
Abstract A method of treating a wound site wherein a porous, adhesive backed dressing is utilized. A vacuum and/or heat is applied to the wound site through the dressing so as to draw the tissue adjacent the wound site to the dressing so as to minimize trauma to the wound and increase the adherence of the adhesive.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
52 words
A method of treating a would comprising the steps of: applying a porous, adhesive backed dressing to a wound site; and applying a vacuum to said wound site through said porous dressing to draw the tissue adjacent the wound into bonding contact with said adhesive without depressing said dressing into the wound.
Claim 2
Independent Claim
52 words
A method of treating a would comprising the steps of: applying a porous, adhesive backed dressing to a wound site; and applying a vacuum to said wound site through said porous dressing to draw the tissue adjacent the wound into bonding contact with said adhesive without depressing said dressing into the wound.
Claim 3
Dependent Claim
40 words
The method in accordance with claim 1 wherein, the step of vacuum application further includes generating said vacuum with a vacuum line which when open has a negative air flow of approximately 1 standard cubic foot per minute or greater.
Claim 4
Dependent Claim
49 words
The method in accordance with claim 1 comprising the further step of applying heat to said dressing to cause said adhesive to flow and to drive moisture from the wound site and thereby improve bonding contact between said dressing and the tissue without depressing said dressing into the wound.
Claim 5
Dependent Claim
22 words
The method in accordance with claim 3 wherein said step of vacuum application is performed simultaneously with said step of heat application.
Claim 6
Dependent Claim
25 words
The method in accordance with claim 3 wherein said step of heat application further includes heating said dressing to between 40° C. and 80° C.
Claim 7
Dependent Claim
22 words
The method in accordance with claim 4 wherein said step of vacuum application is performed simultaneously with said step of heat application.
Claim 8
Independent Claim
66 words
A method of treating a wound comprising the steps of: applying a porous, adhesive backed dressing to a wound site; and applying heat to said dressing through said porous dressing to cause said adhesive to flow and to drive moisture from the wound site and thereby improve bonding contact between said dressing and the tissue adjacent the wound site without depressing said dressing into the wound.
Claim 9
Independent Claim
66 words
A method of treating a wound comprising the steps of: applying a porous, adhesive backed dressing to a wound site; and applying heat to said dressing through said porous dressing to cause said adhesive to flow and to drive moisture from the wound site and thereby improve bonding contact between said dressing and the tissue adjacent the wound site without depressing said dressing into the wound.
Claim 10
Dependent Claim
26 words
The method in accordance with claim 7 wherein said step of heat application further includes heating said dressing to be between 40° C. and 80° C.
Claim 11
Independent Claim
60 words
A device for use with a porous, adhesive backed dressing for treating a wound site, said device including: vacuum means for applying suction to said wound site through said porous dressing to draw the tissue adjacent the wound site into bonding contact with said adhesive without depressing said dressing into the wound; and grip means for supporting said vacuum means.
Claim 12
Independent Claim
60 words
A device for use with a porous, adhesive backed dressing for treating a wound site, said device including: vacuum means for applying suction to said wound site through said porous dressing to draw the tissue adjacent the wound site into bonding contact with said adhesive without depressing said dressing into the wound; and grip means for supporting said vacuum means.
Claim 13
Dependent Claim
24 words
A device in accordance with claim 9 further comprising a plate affixed to said grip means, and said vacuum means passing through said plate.
Claim 14
Dependent Claim
54 words
The device in accordance with claim 10 further comprising means for heating said plate so that heat is applied to the dressing to cause said adhesive to flow and to drive moisture from the wound site and thereby improve bonding contact between said dressing and the tissue without depressing said dressing into the wound.
Claim 15
Independent Claim
77 words
A device for use with an adhesive backed porous dressing for treating a wound site said device including: a grip; a plate affixed to said grip; and means for heating said plate so that heat is applied through said porous dressing to cause said adhesive to flow and to drive moisture from the wound site and thereby improve bonding contact between said dressing and the tissue adjacent the wound site without depressing said dressing into the wound.
Claim 16
Independent Claim
77 words
A device for use with an adhesive backed porous dressing for treating a wound site said device including: a grip; a plate affixed to said grip; and means for heating said plate so that heat is applied through said porous dressing to cause said adhesive to flow and to drive moisture from the wound site and thereby improve bonding contact between said dressing and the tissue adjacent the wound site without depressing said dressing into the wound.
