| 20120000487 | CANNULA CLEANING DEVICE - A method for making a device for cleaning the cannula of a medical instrument and for cleaning a cannula with the device in which the distal end of an elongated support and guiding member, having proximal and distal ends, is secured in a cleaning element 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 a liquid enzymatic cleaning solution is absorbed in the coating and then dried. When used to clean a cannula the cleaning element is immersed in water to wet the enzymatic cleaner inserted into the cannula and manipulated from the proximal end of the elongated support. | 01-05-2012 |
