Benefits of technology

This patent describes an improved sterilization wrap that uses two layers of material. The wrap is easy to use, wicks moisture from the sterilized article, and includes a chemical visual indicator to confirm adequate sterilization conditions. The sterilization wrap is less costly to manufacture than conventional wraps. The technical effects of this invention include improved sterilization efficiency, ease of use, and reduced manufacturing costs.

Problems solved by technology

The wrapping of surgical instruments with two separate sheets of sterilization wrap obviously is labor intensive in that the clinician must first place the instruments on one sheet of sterilization material and wrap the instruments, and then place the wrapped package on another sheet of sterilization material and again wrap the package containing the instruments.
With two of the edges being unbonded, it is possible that the sheets become misaligned so that if a sharp object penetrates both sheets, the resulting holes in each sheet could also become misaligned, thus reducing ones ability to determine whether or not there is a hole through both sheets.
However, both the One Step® product and the Simul-Wrap® product have certain drawbacks.

Embodiment Construction

[0035] Referring now more particularly to FIG. 2, there is provided sterilization wrap 30 having a first sheet or layer 32 and a second layer or sheet 34. Preferably, the first layer 32, which is the outside layer, is made of SMS. The first layer 32 is sometimes referred to herein as a sheet of sterilization material. The second layer 34, which is the inside layer, may be made of cellulose or some other absorbent material, which absorbs liquids and aids in drying and which also permits a sterilant, such as steam or ethylene-oxide, to pass therethrough, but inhibits pathogens from passing therethrough. Other absorbent materials could include, but are not limited to, absorbent synthetics such as hydrophillic spunmelt polyolefins, polyester, nylon, as well as polyrayons and bicomponent fibers. The second layer 34 is sometimes referred to herein as a sheet of absorbent material. In order to reduce the cost of the sterilization wrap 30 while not reducing its effectiveness, the second or ...

Abstract

There is provided an improved sterilization wrap and a method for using the improved sterilization wrap to sterilize an article. The wrap is made of at least one sheet, and preferably two sheets, of sterilization material and in some embodiments, includes an additional sheet which may be made of an absorbent material. The sheet of absorbent material may have a smaller perimeter than at least one sheet of sterilization material. One side of at least one sheet of sterilization material includes a central portion. The absorbent material may be attached to the central portion of at least one sheet of sterilization material. The article to be sterilized is placed on the sterilization wrap and is then wrapped. The absorbent material provides sterility protection for the article in addition to the at least one sheet of sterilization material and also wicks moisture away from the article after sterilization has taken place. A visual indicator may be provided to indicate whether or not the article has been exposed to adequate sterilization conditions.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to sterilization wrap. More particularly, it relates to sterilization wrap utilizing two layers or sheets of material. [0002] Reusable medical instruments must be sterilized prior to each use. Normally, these instruments are exposed to a sterilant to achieve sterilization. As used herein, the term steriliant is meant to refer to the sterilization effectors that are conventionally utilized with sterilization wrap, sterilization techniques, including but not limited to steam, ethylene-oxide, plasma, or the like. In order for the instruments to remain sterile after the sterilization procedure, the instruments must be wrapped in a material called sterilization wrap prior to the sterilization procedure. [0003] The most common type of sterilization wrap is a three-ply laminate consisting of a layer of melt blown polypropylene sandwiched between two layers of spun bond polypropylene. The wrap includes bond points all across the face...
