Abstract

The invention concerns a back table cover (1) for an operating room back table with different surgical instruments (2) wrapped in it such as Mayo stand covers, operating room drapes, adhesive strips, napkins, stockings, etc that is encased in a packaging (26).

The invention is based on the problem of creating a table cover of the initially-cited kind in a quickly produced vacuum packaging (26) from which the table cover (1) can be removed undamaged and sterile with its surgical instrument set (2).

This problem is solved according to the invention in that the folded table cover (1) is provided with an air-permeable zone (17, 20, 29, 30, 34) leading to the interior from at least one of its outer areas (18, 18a).

Claims

1. A liquid-impermeable and substantially air-impermeable back table cover for an OR back table with different enclosed surgical instruments such as Mayo stand covers, operating room drapes, adhesive strips, napkins, or stockings, that is encased by a packaging, wherein at least one of the outer areas of a folded table cover are provided with an air-permeable zone leading to the interior, said air-permeable zone serving to provide the table cover with the quality that it may be placed in packaging that can be quickly evacuated using a low-pressure evacuation procedure without the table cover inflating during such procedure.

2. A table cover according to claim 1 wherein the air-permeable zone is in a fold edge of the table cover.

3. A table cover according to claim 1 wherein the air-permeable zone is in the outside of the table cover.

5. A table cover according to one or more of claims 1-4 wherein the air-permeable zone consists of slots in the table cover that are covered by a plastic film.

6. A table cover according to claim 5 wherein the plastic film is adhered, welded or embossed to the table cover at the two ends of each slot and to the lengthwise slot side and to the lengthwise slot side assigned to the interior of the table cover.

7. A table cover according to one or more of claims 1-4 wherein the air permeable zone includes a membrane which is permeable to air from the inside to the outside and visa versa but is impermeable to liquids and solids.

8. A table cover according to claim 7 wherein the membrane consists of Tyvek fleece or another fleece or a tissue material.

9. A table cover according to claim 8 wherein the outer edges of the membrane are tightly glued, welded or embossed to the table cover.

10. A table cover according to one or more of claims 1-4 wherein the air-permeable zone consists of an air channel that is formed either by an inserted tube extending in the interior of the folded table cover or by a channel formed by spacers between surfaces of the folded layers and extending into the interior.

11. A table cover according to one or more of claims 1-4 wherein the air-permeable zone consists of an air channel that is formed by at least one interruption in an adhesive layer running parallel to a lengthwise side of the table cover or by a channel formed by spacers between surfaces of the respective folded layers adjacent to the interruption.

12. A table cover according to claim 11 wherein the adhesive layer of the table cover is between two separate plastic film parts that are reconnected by the adhesive layer.

13. A table cover according to one or more of claims 1-4 wherein the table cover is in a vacuum packaging.

14. A table cover according to claim 13 wherein the vacuum packaging has a peel seal on at least two side edges.

4. A table cover according to claim I wherein the air-permeable zone is between two folded surfaces of the table cover.
