REMOVABLE WOUND BANDAGE AND METHOD FOR TEMPORARILY CLOSING AND DRAINING OPEN WOUND Russian patent published in 2005 - IPC

FIELD: medical engineering.

SUBSTANCE: device has liquid-permeable porous lining that is to be placed on or in a wound, flexible plastic film having a set of holes distributed over its surface, liquid-impermeable film napkin and connection means. The porous lining has foamed polymer material having interconnecting cells. The plastic film makes contact with porous lining surface and is between wound surface and the lining when used. The film napkin is placed above the porous lining and is sticky along its perimeter to provide sealing in skin area surrounding the wound. The connection means passes through the film napkin and communicates to porous lining via liquid flow for making connection to negative pressure source for stimulating fluid flow discharged from the wound. Another embodiment has removable wound bandage usable in particular for treating large wounds requiring draining fluids. It has the first porous lining, the second porous lining, elastomer envelope, film napkin and tubular connection means. The first liquid-permeable porous lining contacts the wound and has foamed lining having foamed material based on polymer built of interconnecting cells and isolated transverse holes. The elastomer envelope has the first and the second sheets of elastomer film soldered along their periphery and enveloping said foamed lining. Each of the first and the second elastomer film sheets has spaced-apart holes. The holes in the second sheet are justified with said spaced-apart holes in the first sheet. The second liquid-permeable porous lining is to be placed under the first porous lining. It has foamed polymer material having interconnecting cells. The liquid-impermeable film napkin is placed above the second porous lining. The first porous lining is placed above the wound. The film napkin is sticky along its perimeter to glue the napkin to skin area surrounding the wound. The tubular connection means passes through said film napkin and communicates to porous lining via liquid flow for making connection to negative pressure source for stimulating fluid flow discharged from the wound. The third embodiment has the first elastomer film sheet having spaced-apart holes deviated from spaced-apart holes in the foamed lining. The second elastomer film sheet has spaced-apart holes adjusted to the spaced-apart holes in the foamed lining.

EFFECT: simplified usage; accelerated wound healing.
