Abstract

A disinfectant swab is disclosed which comprises a pouch sized for protecting a luer valve. The pouch preferably has shape memory for grasping the luer valve after the pouch as been advanced over the luer valve. The pouch includes a disinfectant along at least one of a inner surface and an outer surface. In one example, the shape memory can be providing by at least one elastic portion. In one embodiment the pouch has at least one disinfectant along the outer surfaces so that the outer surface of the swab can be used to prep skin, drug vials and the like. The pouch can be sized to elastically grasp on a plurality of types of luer valves and/or to elastically grasp on a tube having the approximate outer diameter of a luer lock connector or another portion of a luer lock connector. The pouch can be comprised of elastic foam and/or can have a flattened configuration when stored and/or can be stored in a flat tear able sealed package.
