Abstract
A dressing system for cooling skin or a wound site on a subject comprises a dressing having a reservoir for holding a liquid. The dressing may be configured for placement proximate to a postoperative surgical wound site of the subject or on the facial area of the subject. The dressing system includes a cooling chamber external to the dressing configured to cool the liquid. The dressing system includes a pump configured to circulate the liquid between the cooling chamber and the reservoir. The dressing system may include a suction element for applying suction at, or proximate to, the dressing for removing sweat or wound drainage.
Claims21
A dressing system, comprising:
- a dressing including a reservoir;
- a cooling chamber external to the dressing;
- a coolant disposed at least partially around the cooling chamber;
- a cooled liquid;
- a cooled liquid hose for circulating the cooled liquid between the cooling chamber and the reservoir of the dressing;
- a suction element for providing negative pressure at the dressing;
- a drain cavity;
- a drain hose for moving material suctioned from the suction element to the drain cavity, wherein the material is kept separate from the cooled liquid;
- a pump configured to circulate the cooled liquid between the cooling chamber and the reservoir of the dressing and configured to create suction to the suction element to the drain hose;
- and
- a pump valve for modulating suction to the drain hose and to the cooling hose.
A method of promoting healing in a subject, the method comprising:
- placing a dressing system at, or proximate to, skin of the subject, the dressing system including:
- a dressing including a reservoir;
- a cooling chamber external to the dressing;
- a cooled liquid;
- a cooled liquid hose for circulating the cooled liquid between the cooling chamber and the reservoir of the dressing;
- a suction element for providing negative pressure at the dressing;
- a drain cavity;
- a drain hose for moving material suctioned from the suction element to the drain cavity, wherein the material is kept separate from the cooled liquid;
- a pump configured to circulate the cooled liquid between the cooling chamber and the reservoir of the dressing and configured to create suction to the suction element to the drain hose;
- and
- a pump valve for modulating suction to the drain hose and to the cooling hose, and
- circulating the chilled liquid from the cooling chamber to the reservoir of the dressing.
A method of cooling a skin site of a subject, the method comprising:
- placing a dressing system at, or proximate to, skin of the subject, the dressing system including:
- a dressing including a reservoir;
- a cooling chamber external to the dressing;
- a coolant disposed at least partially around the cooling chamber;
- a cooled liquid;
- a cooled liquid hose for circulating the cooled liquid between the cooling chamber and the reservoir of the dressing;
- a suction element for providing negative pressure at the dressing;
- a drain cavity;
- a drain hose for moving material suctioned from the suction element to the drain cavity, wherein the material is kept separate from the cooled liquid;
- a pump configured to circulate the cooled liquid between the cooling chamber and the reservoir of the dressing and configured to create suction to the suction element to the drain hose;
- and
- a pump valve for modulating suction to the drain hose and to the cooling hose, and
- circulating the chilled liquid from the cooling chamber to the reservoir of the dressing.
