Abstract
A method of cleaning precleaning the header of a used dialyzer is provided. The method includes providing a precleaner header selectively coupled to a dialyzer header cap. The precleaner header includes a needle having an inlet in fluid communication with a source of cleaning fluid and an outlet in fluid communication with the header cap. An incoming source of cleaning fluid is introduced into the needle at a pressure above ambient pressure and an incoming source of air is introduced at a pressure above ambient pressure into the incoming cleaning fluid stream. The cleaning fluid containing air is discharged into the dialyzer header and cleans the dialyzer header by circulating therewith in. A waste stream is generated and drained from the dialyzer header through the precleaner header.
