초록 ▼

Medical instruments, including stainless steel, plastic tubing, and the like, are sterilized in a portable apparatus that provides a low volume, high pressure flow of continuously circulating water containing about 2 to 6 ppm of ozone. The portable apparatus includes a housing having an open chamber for containing medical instruments. Within the housing are a high voltage transformer, an ozone generator, and a high pressure, low volume pump for circulating ozonated water. A lid for the chamber is provided with carbon substantially to preclude ozone from escaping from the chamber into the atmosphere outside the housing. The lid includes a safety switch so that the apparatus will not operate unless the lid is in place.

Apparatus for sterilizing medical instruments comprising: (a) a housing; (b) an instrument sterilizing pan for containing instruments to be sterilized, said pan being integral with said housing and having an open top for receipt and removal of medical instruments, said pan being positioned for receiving a recirculated flow of water containing ozone sufficient for immersion contact of the medical instruments and sufficient to sterilize the medical instruments, said pan having an aperture positioned for gravity discharge of the water containing ozone; (c) an openable lid for said instrument sterilizing pan, said lid comprising a perforated outer shell and an ozone destroying substance located within said outer shell, whereby ozone that escapes from the water is destroyed upon contact with said ozone destroying substance; (d) means for recirculating flow of the water containing ozone through said instrument sterilizing pan at a pressure of from at least about 25 to 40 psig and at a rate of from at least about 1 to 4 gallons per minute, said recirculating means including an ozone generator located within said housing for generating ozone, said ozone generator comprising at least one mercury-free corona tube spaced from a stainless steel jacket, said recirculating means also including a venturi positioned for injecting ozone from said ozone generator into the water containing ozone in a concentration of from about 0.2 to 0.6 ppm, a pump having a fluid intake and a fluid discharge, a first fluid flow conduit interconnecting said instrument sterilizing pan and said intake side of said pump for flow from said pan to said pump, a second fluid flow conduit interconnecting said venturi with said discharge side of said pump, a third fluid flow conduit interconnecting said venturi with said pan for recirculating flow of the water containing ozone through said pan, and a fourth fluid flow conduit interconnecting said venturi and said ozone generator, said venturi receiving ozone gas from said ozone generator and injecting ozone into the water for supply of water containing ozone to said pan; and (e) a magnetic safety switch electrically connected to said lid for preventing operation of said recirculating means when said lid is removed.
