HOUSING FOR A STERILIZATION MONITORING DEVICE

摘要

A self-contained sterilization monitoring device, for use in a sterilization chamber for monitoring a sterilization cycle, has a sterilant challenge load (3) and electronic means (7, 8) electrically-connected to the challenge load for determining whether or not sterilant has penetrated the challenge load adequately during a sterilization cycle. A welded, sterilant-resistant outer casing (2) provides respective compartments (20, 21) for containing the sterilant challenge load and the electronic means, the compartment (20) for the electronic means being at a reduced pressure to protect the electronic means from the temperature conditions outside the outer casing. A window (10), which is a press-fit in the casing (2), allows the transmission of data in the form of optical radiation signals to/from the electronic means in the compartment (20).
