Biological indicator with integral package
A biological indicator for determining the effectiveness of a sterilization process is disclosed having a package and carrier integral therewith. The package includes a first sheet and a second sheet having a bottom portion, side portions and a top portion. The first and second sheets are joined together generally along a periphery of the first and second sheets by a peelable adhesive. A carrier having a plurality of spores thereon for determining the effectiveness of a sterilization process is attached to the package between the first and second sheets and at least a portion of the resealable adhesive. The package may be opened and subsequently partially or fully closed to enclose the carrier.
1. A biological indicator for determining the effectiveness of a sterilization process comprising:
a package having a first sheet and a second sheet including a bottom portion, side portions and a top portion,
said first and second sheets being joined together along a periphery of said first and second sheets by a peelable adhesive or a mechanical seal or a combination of a peelable adhesive and a mechanical seal, and
a carrier having a plurality of spores thereon for determining the effectiveness of said sterilization process and integrally affixed to the interior of said package at said bottom portion of said package,
wherein said package may be opened at said top portion of said package and subsequently partially or fully closed to enclose said carrier.
2. The biological indicator of claim 1 wherein the peelable adhesive or the mechanical seal is resealable wherein said package may be opened and subsequently partially or fully closed by said peelable adhesive or by said mechanical seal.
3. The biological indicator according to claim 2 wherein said top portion of said package includes first and second flaps.
4. A biological indicator according to claim 1 wherein said carrier includes a well for holding said plurality of spores.
5. The biological indicator according to claim 4 wherein said carrier comprises a strip and is made from a material selected from the group consisting of steel, plastic, polymer, ceramic or a combination thereof.
6. The biological indicator according to claim 1 wherein said first and second sheets are made of a non-woven spunbond fiber material.
7. The biological indicator according to claim 1 wherein said package includes at least one additional sheet.
8. The biological indicator of claim 1 wherein said carrier comprises a disk.
9. A method of using a biological indicator for determining the effectiveness of a sterilization process comprising:
(a) providing a biological indicator having a package having a first sheet and a second sheet including a bottom portion, side portions and a top portion, said first and second sheets being joined together along a periphery of said first and second sheets by a peelable adhesive or a mechanical seal or a combination of a peelable adhesive and a mechanical seal, and a carrier having a plurality of spores thereon for determining the effectiveness of said sterilization process integrally affixed to the interior of said package at a bottom portion of said package, wherein said package may be opened and subsequently closed at said top portion of said package to enclose said carrier,
(b) opening said package from said top portion by pulling said first and second sheets to release said first or second sheet from each other by said peelable adhesive or said mechanical seal and exposing said carrier,
(c) placing said biological indicator in a sterilization chamber and subjecting said biological indicator to said sterilization process for determining the effectiveness of said sterilization process, and
(d) after completion of said sterilization process, partially or fully closing said package to enclose said carrier.
10. A method according to claim 9 wherein the peelable adhesive or the mechanical seal is a resealable.
11. A method according to claim 10 wherein said top portion of said package includes first and second flaps.
12. A method according to claim 9 wherein said carrier includes a well for holding said plurality of spores.
13. A method according to claim 12 wherein said carrier comprises a strip and is made from a material selected from the group consisting of steel, plastic, polymer, ceramic or a combination thereof.
14. A method according to claim 9 wherein said first and second sheets are made of a non-woven spunbond fiber material.
15. A method according to claim 9 wherein said carrier comprises a disk.
16. A biological indicator for determining the effectiveness of a sterilization process comprising:
a package having at least one sheet including a bottom portion, side portions and a top portion,
a carrier having a plurality of spores thereon for determining the effectiveness of said sterilization process and integrally affixed to the interior of said package at said bottom portion of said package,
wherein said package may be opened at said top portion of said package and subsequently partially or fully closed to enclose said carrier.
17. The biological indicator of claim 16 wherein said top portion of said package includes first and second flaps.
18. The biological indicator according to claim 16 wherein said carrier includes a well for holding said plurality of spores.
19. The biological indicator according to claim 18 wherein said carrier comprises a strip and is made from a material selected from the group consisting of steel, plastic, polymer, ceramic or a combination thereof.
20. The biological indicator according to claim 16 wherein said package is made of a non-woven spunbond fiber material.
