Abstract
An apparatus and process to clean medical devices, such as endoscopes, that includes an automatic endoscope reprocessor system equipped with a peracetic acid/hydrogen peroxide sensor are described.
Claims20
A process to disinfect an endoscope comprising:
- attaching an endoscope to an automated endoscope reprocessing unit, wherein the endoscope has a lumen having a proximal end and a terminal end;
- treating the endoscope lumen with a first peracetic acid and hydrogen peroxide solution by passing the peracetic acid and hydrogen peroxide solution through the proximal end of the endoscope through to the terminal end of the endoscope to provide a second peracetic acid and hydrogen peroxide solution;
- expelling the second peracetic acid and hydrogen peroxide solution from the terminal end of the endoscope through the lumen;
- and
- measuring the expelled peracetic acid and hydrogen peroxide content after treating the lumen to disinfect the endoscope with a sensor capable of measuring a concentration of the expelled peracetic acid or hydrogen peroxide solution and comparing the concentration of the expelled peracetic acid or hydrogen peroxide solution to a predetermined range.
