Disposable biological indicator test pack for monitoring steam and ethylene oxide sterilization cycles |
摘要 |
Disposable test packs for monitoring the efficacy of steam or ethylene oxide sterilization cycles includes a fiber board housing for a biological indicator. The housing includes two end sections and a midsection. Each end section includes an outer tube and a longer inner tube. The open end of the outer tubes abut the opposing open ends of the midsection to define a seam or gap. The inner tube extends past the seam and telescopes into the midsection. The seam and the close tolerance between the inner tube and the midsection provide a tortuous path for the entry of sterilant into the interior of the housing. The tortuous path has a moisture absorbent surface and is dimensioned to promote intimate contact between the sterilant and the absorbent surface. A second path of entry is provided in the embodiment adapted for use in monitoring ethylene oxide sterilization processes only. A midsection can be made of a transparent, sterilant impermeable material to permit observation of the interior of the housing.
