Separable sterile drape with z-shaped folds
An improved draping system with a drape and a lock device. The drape includes an area defined by a predetermined length and a predetermined width, as well as a selectively separable portion. The drape also has a first perforation, as well as a z-shaped fold over the perforation. The lock device may be a poly seal with a second perforation. The draping system is secured to an operating table to maintain sterility about that operating table. When ready for removal, the draping system is simply pulled in opposite directions. When this occurs, the second perforation breaks, which disengages the lock device. Upon further pulling, the z-shaped fold is unfolded. Further pulling still results in the second perforation breaking.
1. A draping system configured to maintain sterility comprising:
a drape comprising:
an area defined by a predetermined length and a predetermined width;
a selectively separable portion extending along a longitudinal portion; and
a first peripheral edge at a first terminus of the predetermined width and a second peripheral edge at a second terminus of the predetermined width, the first and second peripheral edges adapted to at least partially overlap on another to form a z-shaped fold; and
a lock device configured to maintain the first and second peripheral edges in the z-shaped fold until the lock device is disengaged, the lock device comprising a poly seal with a first perforation extending therethrough,
wherein a second perforation extends substantially parallel to the first peripheral edge and the second peripheral edge.
2. The draping system of claim 1 , further comprising a plurality of handles attached to the area configured to enable the lock device to be disengaged and the z-shaped fold to be unfolded.
3. The draping system of claim 1 , wherein the lock device is at least one piece of adhesive tape.
4. The draping system of claim 1 , wherein the first perforation is configured to allow the lock device to be disengaged; and
wherein the second perforation is configured to allow the drape to be separated once the z-shaped fold is unfolded.
5. A method of using a draping system comprising:
placing a drape system on a sterile surface, the drape system comprising:
a drape comprising:
an area defined by a predetermined length and a predetermined width;
a selectively separable portion extending along a longitudinal portion;
a first peripheral edge at a first terminus of the predetermined width and a second peripheral edge at a second terminus of the predetermined width, the first and second peripheral edges adapted to at least partially overlap on another to form a z-shaped fold; and
a lock device configured to maintain the first and second peripheral edges in the z-shaped fold, the lock device comprising a poly seal with a first perforation extending therethrough,
wherein a second perforation extends substantially parallel to the first peripheral edge and the second peripheral edge;
unfolding the drape system about the sterile surface;
pulling opposite ends of the drape away from one another;
unfolding the z-shaped fold;
breaking the drape about the second perforation; and
maintaining sterility beneath the drape.
6. The method of claim 5 , wherein the pulling step comprises:
grasping at least two handles attached to opposite sides of the drape; and
pulling the handles in opposite directions.
7. The method of claim 5 further comprising the steps of:
wrapping a plurality of straps around the sterile surface; and
affixing ends associated with the plurality of straps to the area to secure the drape to the sterile surface.
8. The method of claim 5 , further comprising the step of disengaging the lock device.
9. The method of claim 5 further comprising the step of:
moving a piece of medical equipment adjacent to the sterile surface.
