Wound treatment system
A disposable dressing forms a compartment around and above a wound site and a volatile antimicrobial compound is allowed to sublimate/evaporate into the compartment. A heating element is included in the dressing, with heat stimulating wound healing and simultaneously accelerating sublimation/evaporation of the antimicrobial compound.
1. A wound treatment system, comprising:
a body structured and arranged to surround a wound area, said body having an opening above the wound area;
a cover attached to the body and covering the opening, said cover suspended above the wound area;
said opening and said cover forming an enclosed and empty wound treatment compartment;
an autonomous heating element incorporated into the body or into the cover; and
a medically useful agent evaporating or sublimating at an accelerated rate above normal body temperature of about 40° C. to about 80° C.
said medically useful agent in fluid communication as a gas or vapor with the wound treatment compartment and with the wound area under the suspended cover.
2. The wound treatment system of claim 1 , wherein an amount of said agent is effective to inhibit bacterial infection of said wound.
3. The wound treatment system of claim 1 , wherein the heating element is structured and arranged to heat said medically useful agent to a temperature sufficient to inhibit bacterial infection of said wound.
4. The wound treatment system of claim 1 , wherein the medically useful agent is located on the autonomous heating element.
5. The wound treatment system of claim 1 , wherein the medically useful agent is located close enough to the heating element to receive radiant heat from the autonomous heating element.
6. The wound treatment system of claim 1 , wherein the cover is a transparent or semi-transparent film.
7. The wound treatment system of claim 1 , wherein the cover is a transparent or semi-transparent dome.
8. The wound treatment system of claim 1 , wherein the medically useful agent is an antimicrobial agent.
9. The wound treatment system of claim 8 , wherein the antimicrobial agent is selected from the group consisting of halogenated hydroxyl ethers, acyloxydiphenyl ethers, and combinations thereof.
10. The wound treatment system of claim 1 , wherein the medically useful agent is impregnated in a strip of an inert carrier.
11. The wound treatment system of claim 1 , wherein the medically useful agent is triclosan impregnated in a strip of melt-spun polymer.
12. The wound treatment system of claim 1 , wherein dimensions of the enclosed wound treatment compartment are adjustable to accommodate wounds of different dimensions.
13. A method of wound treatment, comprising:
enclosing a wound area with a wound treatment system comprising:
a body structured and arranged to surround a wound area, said body having an opening above the wound area;
a cover attached to the body and covering the opening, said cover suspended above the wound area;
said opening and said cover forming an enclosed and empty wound treatment compartment;
an autonomous heating element incorporated into the body or into the cover; and
a medically useful agent evaporating or sublimating at an accelerated rate above normal body temperature of about 40° C. to about 80° C.
said medically useful agent in fluid communication with the compartment,
activating said heating element, thereby heating said medically useful agent;
evaporating or sublimating portions of said medically useful agent to cause vapors of said medically useful agent to fill the enclosed wound treatment compartment; and
contacting said wound area with vapors of said medically useful agent.
14. The method of wound treatment of claim 13 , wherein activating of said autonomous heating element provides radiant heat to said wound area.
15. The method of wound treatment of claim 13 , wherein the cover is a transparent or semi-transparent film.
16. The method of wound treatment of claim 13 , wherein the cover is a transparent or semi-transparent dome.
17. The method of wound treatment of claim 13 , wherein the medically useful agent is an antimicrobial agent selected from the group consisting of halogenated hydroxyl ethers, acyloxydiphenyl ethers, and combinations thereof.
18. The method of wound treatment of claim 13 , wherein the medically useful agent is triclosan impregnated in a strip of melt-spun polymer.
