Abstract
Improved sterilization wraps (30, 44) and methods for using the improved sterilization wraps (30, 44) to sterilize articles (36). The wraps (30, 44) are made of at least one panel (32, 46, 60) of sterilization material and an additional panel (34. 52, 76) which in some embodiments is made of an absorbent material (34, 52). The additional panel (76) of material may be bonded to the first panel (60) at approximately at a forty-five degree angle to the first panel (60). The article to be sterilized (36) is placed on the sterilization wrap (30, 44), is wrapped, and sterilant is applied to the wrapped article (36). The absorbent material (34, 52) provides sterility protection for the article (36) in addition to the panel (32, 46, 60) of sterilization material and also wicks moisture away from the article (36) after sterilization has taken place. A chemical visual indicator (42, 56, 88) is provided to indicate whether or not the article (36) has been exposed to adequate sterilization conditions.
