ABSTRACT:
A permanent record test device tests the efficiency of a steam sterilizer apparatus to create a vacuum satisfying the Bowie-Dick test procedure. A sheet of selectively porous material such as one hundred pound blotter paper having a steam sensitive indicator ink printed thereon is laminated between layers of steam and air impermeable polymeric material to substantially occlude the sheet from ambient atmosphere, except for a small metering region. The small metering region may include a hole punched through the laminated sheet. Two parallel and spaced apart strips can be used with a metering hole punched at one end of each of the strips or, alternatively, a metering hole is punched at one end of any one of the strips and the strips can be connected with a fluid passageway at the opposite end of the strips. Strips other then straight strips can be used, e.g., an L-shaped strip can be used with a V-shaped strip.
