METHOD FOR MAKING OF A CANNULA CLEANING DEVICE

摘要

A device for cleaning the cannula of a medical instrument includes an elongated support and guiding member which has proximal and distal ends. A cleaning element secured to the distal end is formed of a substantially reticulated hydrophobic polyurethane foam having a plurality of pores within its structure which define surfaces in the foam. The surfaces of the polyurethane foam are coated with a hydrophilic polyurethane coating and an enzymatic cleaning solution is absorbed in the coating.
