Abstract

A drape ( 600 ) suitable for covering non-planar surfaces of equipment ( 1201 ) is provided. The drape ( 600 ) facilitates quick and efficient deployment while ensuring that a sterile field established by a drape portion ( 601 ) is not compromised. The drape ( 600 ) can include a drape wrapping layer ( 209 ) wrapped about a drape portion ( 601 ) that is formed initially with two abutting elongated accordion fold stacks ( 604,605 ). Non-sterile personnel ( 801 ) can handle the drape wrapping layer ( 209 ) to position the drape ( 600 ) along surfaces of the equipment ( 1201 ) without touching the sterile drape portion ( 601 ). Sterile personnel can then expand the abutting elongated accordion fold stacks ( 604,605 ) to drape the surfaces of the equipment ( 1201 ).

First claim

What is claimed is:

1. A method of manufacturing a drape, comprising:
configuring a sterile drape with accordion folds to form two abutting elongated accordion fold stacks linked by a bottom section;
wrapping the sterile drape with a drape wrapping layer to form a wrapped drape; and
folding the wrapped drape with one or more book folds to form a folded drape.

2. The method of claim 1 , further comprising attaching coupling devices to the sterile drape prior to the wrapping.

3. The method of claim 2 , further comprising attaching one or more indicators to the drape wrapping layer.

4. The method of claim 1 , the drape wrapping layer having a wrapping layer length and a wrapping layer width, the two abutting elongated accordion fold stacks defining a stack width and a stack length, the stack width is less than the wrapping layer width and the stack length is less than the wrapping layer length.

5. The method of claim 1 , the sterile drape pellucid and the drape wrapping layer opaque.

6. The method of claim 1 , the sterile drape polyethylene.

7. The method of claim 1 , the drape wrapping layer a Central Sterile Reprocessing (CSR) wrap.

8. The method of claim 1 , the configuring comprising coupling attachment devices to distal ends of the sterile drape.

9. The method of claim 8 , the attachment devices comprising portions of hook and loop fasteners.

10. The method of claim 1 , the configuring comprising configuring indicators to provide instructions in how to fold and unfold the sterile drape.

11. The method of claim 1 , the configuring comprising configuring indicators to indicate which portion of the drape wrapping layer is a bottom portion when unfolded.

12. The method of claim 1 , the drape wrapping layer comprising a first envelope portion and a second envelope portion, the first envelope portion being wrapped about one of the two abutting elongated accordion fold stacks and the second envelope portion being wrapped about another of the two abutting elongated accordion fold stacks to form an envelope folded drape.

13. The method of claim 12 , the envelope folded drape comprising a first book fold and a second book fold, the first book fold and the second book fold resulting in a first envelope folded drape end and a second envelope folded drape end abutting along a central portion of the envelope folded drape to form a partially folded drape.

14. The method of claim 13 , the partially folded drape comprising a third book fold and a fourth book fold resulting in a first partially folded drape end and a second partially folded drape end abutting to form a semi-folded drape.

15. The method of claim 14 , the semi-folded drape comprising a fifth book fold resulting in a first half of the semi-folded drape sharing a major face with a second half of the semi-folded drape to form the folded drape.

16. The method of claim 15 , the folded drape with one or more indicators indicating which portion of the folded drape is configured as a bottom portion disposed on an outer surface of the folded drape.
