Abstract
A wound dressing having exothermic materials that undergo a chemical reaction to generate heat to produce a desired temperature to promote healing at a wound site, and a phase-change material having a phase-change temperature to absorb heat and maintain the wound dressing at said desired temperature.
Claims19
A wound healing device, comprising:
- a dressing;
- an exothermic material in thermal communication with the dressing;
- and a phase-change material in thermal communication with the exothermic material, the phase-change material having a desired phase-change temperature to maintain the dressing at a temperature to promote healing of the wound.
A method for treating a wound in a human, comprising:
- applying a dressing having an exothermic material and a phase-change material with a phase-change that is at a temperature to promote healing of the wound;
- releasing heat from said exothermic material;
- and absorbing that into the phase-change material so as to change the phase of said phase-change material.
A method of manufacturing a dressing for treating a wound in a human, comprising:
- forming a plurality of pellets of phase-change material having a phase-change temperature of a desired temperature for healing the wound;
- embedding the pellets into the dressing.
