US Patent 11672623 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.
