Abstract
A biological indicator is provided for measuring the effectiveness of a sterilization procedure. The biological indicator comprises a carrier having a microorganism and at least one of a humectant, anti-agglomerating agent or surfactant disposed thereon, the carrier having a solidity of greater than 5%. Various embodiments of a device, kits and methods are disclosed.
Claims34
A biological indicator for measuring effectiveness of a sterilization procedure, the biological indicator comprising:
- a carrier having a microorganism and at least one of a humectant, anti-agglomerating agent or surfactant disposed thereon, the carrier having a solidity of greater than 5%.
A biological indicator for measuring effectiveness of a sterilization procedure, the biological indicator comprising:
- a container comprising growth media and a carrier separated from the growth media, the carrier comprising at least one of a humectant, anti-agglomerating agent or surfactant and spores inoculated thereon.
A method for determining effectiveness of a sterilization procedure with a biological indicator, the method comprising:
- subjecting the biological indicator to a sterilization cycle, the biological indicator comprising a deformable container having a crushable vial disposed therein comprising growth media and a carrier separated from the crushable vial but within the deformable container, wherein the carrier comprises at least one of a humectant, anti-agglomerating agent or surfactant and spores;
- activating the biological indicator by applying pressure to said deformable container to crush the vial so as to allow the growth media and the spores of the carrier to come into contact with each other;
- and incubating the biological indicator for a predetermined period of time to permit any growth of the spores surviving said sterilization cycle to grow in the growth media, wherein the growth provides a determination of the effectiveness of the sterilization procedure.
A kit for determining effectiveness of a sterilization procedure, the kit comprising:
- a biological indicator comprising a container having a vial disposed therein comprising growth media and a carrier separated from the vial but within the container, wherein the carrier comprises at least one of a humectant, anti-agglomerating agent or surfactant and a microorganism inoculated thereon.
