摘要： 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.

摘要： The present invention is a lightweight endoscopic instrument which has a flushing port with a check valve assembly therein. The check valve retains carbon dioxide which is used during endoscopic procedures. Upon removal of the instrument, a pressurized fluid can be connected to the flush port, with internal seals directing the pressurized fluid through an annular space between the stem of the instrument and a central actuating rod or element so that any tissue or blood which may have entered into such annular space is flushed out the distal end of the instrument. The instrument features a knob allowing it to rotate on its longitudinal axis while having a handle that can be held in a fixed position by the surgeon. An index mechanism is provided to audibly and/or visually give an indication at preset increments of rotation. The instrument is lightweight to decrease fatigue and is simply and economically constructed.
