Abstract

A device for providing a protective seal at an incision provided incident to the insertion of a catheter beneath the skin includes a shield having an adhesive coating on one surface so that the shield adheres to the skin in the area of the incision to prevent bacteria from passing beneath the shield. A tubular sleeve extends outwardly from and is sealed to the shield to define a passageway for the catheter, the sleeve having an inner adhesive coating to provide a seal between the sleeve and catheter so as to prevent bacteria from gaining access to the incision.

Claims

1. A device for providing a protective seal at the locus of an incision provided incident to the insertion of a catheter beneath the skin, said device comprising A. a shield adapted to overlie essentially the entirety of an area of skin encircling the incision, 1. the body of said shield being formed so as to be impervious to the passage of bacteria therethrough and being provided with an opening located within its periphery alignable with the incision to accommodate a catheter, 2. at least a portion of one surface of said shield being provided with an adhesive coating effective to maintain said shield in contact with the skin so as to prevent bacteria from passing beneath said shield and gaining access to the incision, B. a tubular sleeve extending outwardly from the non-adhesive surface of said shield and sealed thereto so as to prevent bacteria from gaining access to said opening in said shield at the juncture of said sleeve and shield, 1. the walls of said sleeve being formed so as to be impervious to the passage of bacteria therethrough, 2. said sleeve defining a passageway in alignment with said opening in said shield and adapted to accommodate the catheter intimately therein, 3. at least a portion of the inner surface of said sleeve being provided with an adhesive coating effective to create a seal between said sleeve and the catheter so as to prevent bacteria from passing between said sleeve and the catheter and gaining access to the incision.

2. said sleeve defining a passageway in alignment with said opening in said shield and adapted to accommodate the catheter intimately therein,

3. at least a portion of the inner surface of said sleeve being provided with an adhesive coating effective to create a seal between said sleeve and the catheter so as to prevent bacteria from passing between said sleeve and the catheter and gaining access to the incision.

4. A device in accordance with claim 1, wherein said shield and sleeve are integral, and wherein said lateral access means is a cut which extends from the outer end of said sleeve along said sleeve and shield to the periphery of said shield so as to facilitate the placement of the device relative to a catheter.

5. A device in accordance with claim 1, wherein essentially the entire inner surface of said shield and essentially the entire inner surface of said sleeve are provided with an adhesive coating, and wherein a removable backing sheet overlies each coating to protect it prior to use.

6. A device in accordance with claim 1, wherein said adhesive coating contains an antibacterial chemical.

7. A device for providing a protective seal at the locus of an incision provided incident to the insertion of a catheter beneath the skin, the device comprising:

A. a flat shield having top and bottom surfaces adapted to overlie essentially the entirety of an area of skin encircling the incision,
