A system for reprocessing and sterilizing a previously used endoscope having at least one lumen is disclosed. The reprocessing system includes a reaction chamber into which individual chemical components of a sterilant are transferred by pneumatic force. The system includes a central processor which controls the asynchronous reprocessing and sterilization of at least two endoscopes. A novel sterilant is also disclosed. Also disclosed is a combination of the sterilization device and the sterilant and methods of using the same.

Endoscope reprocessing and sterilization system

The present invention relates to a two-part or multi-part concentrate system for preparing an activated solution which can be diluted with water to a use-dilution solution having improved anti-corrosive properties at room temperature. The concentrate system contains a first component containing at least one oxidizing agent, preferably hydrogen peroxide and a second component containing at least formic acid in a concentration of about 25 wt %. At least one corrosion inhibitor and at least one surfactant are also included in the concentrate system. When mixed and diluted, the resulting solution is excellent in its sterilization and anti-corrosive properties.

Multi-part anti-microbial concentrate system, activated solution, use-dilution solution, method of making same, and method of sterilizing with the use-dilution solution

Provided is an anti-microbial composition containing an ester of formic acid, an oxidizer, performic acid and water. Also provided is a premix for making the anti-microbial composition having two parts. One part contains the ester of formic acid and a second part contains the oxidizer. Another method is provided for making the anti-microbial composition in which the ester of formic acid is combined with the oxidizer and water. A further method is provided for sterilizing medical devices, including dialyzer filter modules, wherein the anti-microbial composition is capable of a 1:1 to a 1:12 dilution with water.

Room temperature sterilant for medical devices

Provided is an anti-microbial composition containing an ester of formic acid, an oxidizer, performic acid and water. Also provided is a premix for making the anti-microbial composition having two parts. One part contains the ester of formic acid and a second part contains the oxidizer. Another method is provided for making the anti-microbial composition in which the ester of formic acid is combined with the oxidizer and water.

Premix for room temperature sterilant

Room Temperature sterilant

Provided is an anti-microbial composition containing an ester of formic acid, an oxidizer, performic acid and water. Also provided is a premix for making the anti-microbial composition having two parts. One part contains the ester of formic acid and a second part contains the oxidizer. Another method is provided for making the anti-microbial composition in which the ester of formic acid is combined with the oxidizer and water. Also provided is a method for sterilizing devices by contacting the surface of the device with the anti-microbial composition containing the ester of formic acid, an oxidizer, performic acid and water.
