Self-contained cryothetrapy and suction system

摘要

A method for treating wounds, comprised of the application of reduced pressure to a wound site and alteration of the temperature over said wound. A system for wound healing, comprising: a substantial impermeable drape sized to cover and enclose the wound creating a reservoir and adapted to maintain reduced pressure at the site of the wound; a sterilizable porous cooling pad incorporated into a wound sponge adapted to provide localized cooling to said wound, said cooling pad located between said wound and said cover or over the drape; a reduced pressure supply mechanism capable of providing subatmosphere pressure over said wound site.

主权项

1. A system to promote the healing of a wound, comprising:
(a) a flexible drape sized to seal in a wound site, and adapted to maintain a substantial airtight watertight reservoir over the wound site, wherein said flexible drape has a resealable connector in the middle; (b) a cooling pad, placed over the wound site and is in fluid communication with a coolant supply which has a control for temperature of outgoing coolant; and (c) a reduced pressure mechanism including
(i) a control unit disposed within a housing, the control unit including a vacuum source; and(ii) a collection storage having an interior wall defining an internal chamber in fluid communication with the vacuum source of the reduced pressure mechanism and with said reservoir over the wound site through a vacuum port for collecting exudates removed from the wound site under influence of the vacuum source; wherein said reduced pressure mechanism maintains a pressure from about 2 in. Hg below atmospheric pressure to about 7 in. Hg below atmospheric pressure at the reservoir and wherein said coolant is maintained at a temperature from about 30° F. to about 50°.
