Intended Use

The Getinge GSS67N Series Steam Sterilizer is intended for use by health care facilities to sterilize wrapped and unwrapped, porous and nonporous heat and moisture stable items such as surgical instruments and linens by means of pressurized steam. The GSS67N Series Steam Sterilizer is available in 3 models differentiated by chamber length; GSS67N Model 6710 (39 inch chamber), GSS67N Model 6713 (51 inch chamber) and GSS67N Model 6717 (67 inch chamber).

Device Story

The Getinge GSS67N Series Steam Sterilizer is a floor-standing device used in healthcare facilities to sterilize heat and moisture-stable items. It utilizes pressurized saturated steam as the sterilizing agent. The device features three chamber lengths (39, 51, and 67 inches) and employs gravity/downward displacement with positive pulse conditioning and pressure/vacuum pulsing for air removal. A vacuum pump is used for air removal. The system is operated via an updated touchscreen display, which allows users to select from 11 standard cycles (Prevac, Gravity, IUSS, Liquids, and Leak Test) or designate custom cycle names. The control system sequences and monitors all cycle phases, providing audible and visual notifications of parameter deviations. The device ensures sterility by achieving specific time-at-temperature requirements (F0 value of at least 12) and biological indicator kill. It benefits patients by ensuring the sterility of surgical instruments and linens, thereby reducing the risk of healthcare-associated infections.

Clinical Evidence

No clinical data. Bench testing only. Validation performed per ANSI/AAMI ST8:2013. Testing included empty chamber thermal distribution, fabric process challenge packs, wrapped instrument process challenge devices, IUSS unwrapped nonporous process challenge devices, and liquid load cycles.
