11. A covering for an aseptic treatment site, comprising:

a flexible substrate having opposite first and second surfaces, and which defines a fenestration which permits access to an aseptic treatment site on a patient;

a first adhesive region borne on the second surface of the flexible substrate, and which substantially surrounds the fenestration; and

a flexible transparent cover hingedly affixed on the first surface of the flexible substrate, and which is repeatably moveable along a course of travel between (i) a first, covering position relative to the fenestration which permits observation of the aseptic treatment site, to (ii) a second, uncovered position relative to the fenestration which permits access to the aseptic treatment site, and (iii) back to the first, covering position without contacting an area bound by the fenestration.

12. A covering as claimed in claim 11, and wherein the flexible substrate comprises first and second regions, with the flexible transparent cover being positioned completely within the first region, and wherein the first region may be selectively detached from the second region.

13. A covering as claimed in claim 12, wherein the first region comprises first and second portions with the first portion defining the fenestration, and wherein the second portion may be selectively detached from the second region.

14. A covering as claimed in claim 12, wherein a plurality of weakened areas are formed in the substrate so as to surround the first region, and wherein the first region is detachable from the second region by tearing the substrate along the plurality of weakened areas.

15. A covering as claimed in claim 11, further comprising a second adhesive region borne by the flexible, transparent cover, and which releasably adhesively affixes the flexible transparent cover to the first surface of the flexible substrate when the flexible transparent cover is in the first, covering position.

16. A covering as claimed in claim 15, and wherein the first adhesive region affixes the flexible substrate on the patient and in substantially sealing relation about the aseptic treatment site, and wherein the first adhesive region has a first adhesive strength, and wherein the second adhesive region has a second adhesive strength which is less than the first adhesive strength.

17. A covering as claimed in claim 15, and wherein the first adhesive region releasably affixes the flexible substrate on the patient, and wherein the second adhesive region releasably affixes the transparent cover in covering relation relative to the fenestration, and further allows the transparent cover to be repeatedly moved from (i) the first, covering position relative to the fenestration, to (ii) the second, uncovered position and back to (i), without adhesively detaching the first adhesive region from the patient.

18. A covering for an aseptic treatment site comprising:

a substrate defining a fenestration which permits selective access to an aseptic treatment site on a patient; and

a transparent cover which is releasably adhesively affixed to the substrate and positioned in covering relation relative to the fenestration, said transparent cover having an upper surface and a lower surface, said lower surface having a pattern of adhesive thereon for releasably adhesively affixing the transparent cover to the substrate, wherein a portion of the lower surface of the transparent cover that extends over the fenestration is free of adhesive,
