Abstract

See full text

A portable table-top steam sterilizer having a sterilization chamber contained within a double-walled vacuum-sealed vessel. Pre-heated water is delivered from a self-contained water supply infrastructure under a positive air pressure to the chamber. The pre-heated water is converted to steam within the sterilization chamber for a sterilization cycle after which, the steam is rapidly removed by vacuum and the sterilization chamber and items placed therein are rapidly cooled and dried by a turbulent flow of air. The air supply is provided by concurrent application of positive and negative air pressures from a self-contained airflow piping infrastructure releasably engaged with an external supply of compressed air. The mixtures of steam, water and air exhausted from the sterilization chamber are directed into a condenser wherein they are cooled into an air/water mixture which is transferred to an air/water separator device wherein water is separated from the air/water mixture, said water recyclable within the self-contained water supply infrastructure.
