Chest wound seal for preventing pneumothorax and including means for relieving a tension pneumothorax
First Claim
1. An occlusive dressing for a chest wound comprising:
- a flexible sheet for providing a fluid and debris barrier;
an adhesive layer carried on a bottom side of said sheet for adhering said sheet to skin surrounding the chest wound;
a collection chamber formed in said adhesive layer by the exclusion of adhesive from a generally central area of said sheet for being positioned over the wound to receive fluid from the wound; and
, a drainage channel formed in said adhesive layer by the exclusion of adhesive from a selected area of said sheet extending radially outward from said collection chamber to a drain outlet at a peripheral edge of said sheet to drain fluid from said collection chamber out from under said sheet;
wherein said collection chamber and drainage channel have an open position allowing fluid to flow outward from said collection chamber through said drain outlet, and a closed position collapsed against the skin to prevent fluid intake through said drain outlet to prevent fluid from building pressure within the chest cavity.

Abstract
A flexible sheet having an adhesive layer carried on a bottom side. A collection chamber formed in the adhesive layer by the exclusion of adhesive from a central area of the sheet for receiving fluid from the wound. A drainage channel formed in the adhesive layer by the exclusion of adhesive from a selected area of the sheet extending radially outward from the collection chamber to a drain outlet at a peripheral edge of the sheet to drain fluid from the collection chamber. The collection chamber and drainage channel having an open position allowing fluid to flow outward from the collection chamber through the drain outlet, and a closed position collapsed against the skin to prevent fluid intake through the drain outlet. A storage compartment carried by the flexible sheet including a needle and catheter for immediate access in treating a tension pneumothorax.

11. An occlusive dressing for a chest wound comprising:
-
a generally fluid impermeable flexible sheet;
an adhesive layer carried on a bottom side of said sheet for adhering said sheet to skin surrounding the wound; and
,a fluid drain included in said adhesive layer defined by an absence of adhesive on selected areas of said sheet;
wherein said sheet is constructed and arranged to be applied over the wound to position a portion of said fluid drain directly over the wound for receiving fluid from the wound and channeling the fluid out from under said sheet while preventing fluid intake into the wound. - View Dependent Claims (12, 13, 14, 15, 16)

17. An occlusive dressing for a chest wound comprising:
-
a top sheet for providing a fluid and debris barrier;
an adhesive layer carried on a bottom side of said sheet for adhering said sheet to skin surrounding the wound;
a collection chamber formed in said adhesive layer by the exclusion of adhesive from a selected portion of said sheet for receiving fluid from the wound; and
,a drainage channel connected to said collection chamber extending radially outward to a peripheral-edge of said sheet to drain fluid from said collection chamber;
wherein said collection chamber has an open position allowing fluid to flow outward from said collection chamber to said drainage channel, and a closed position collapsed against the skin to prevent fluid intake through said drainage channel to maintain air pressure levels within the chest cavity. - View Dependent Claims (18, 19, 20)

21. An occlusive dressing for a chest wound comprising:
-
an adhesive layer consisting of a hydrogel polymeric composition for placement over the wound;
a flexible sheet carried on a top side of said adhesive layer to form a fluid and debris barrier over said adhesive layer;
a storage compartment carried by said flexible sheet;
a needle carried in said storage compartment adapted for penetrating the chest into the pleural space; and
,a catheter carried in said storage compartment operatively associated with said needle for allowing air to escape the pleural space and relieve a tension pneumothorax;
whereby a penetrating chest wound causing a tension pneumothorax can be sealed and the air pressure causing the tension pneumothorax in the pleural space relieved. - View Dependent Claims (22, 23, 24)
