In medicine, a<unk>  connects to the end of vascular catheters and enable catheter access for infusion and aspiration.<unk> s (also known as NC's) were developed to reduce needlestick injuries, which occurs when the skin is accidentally punctured by a used needle. Needlestick injuries can be very serious and potentially expose a healthcare professional to bloodborne infectious diseases such as HIV/AIDS, Hepatitis B and Hepatitis C. The needless<unk>  should provide safe access to the catheter without the use of needles and enable the following: * Minimize catheter occlusion risk. * Allow for easy and effective decontamination between each use to prohibit microbial entry e.g. via a flat surface which is flush with the housing. Before utilizing a<unk> , it is important to properly disinfect the device to help prevent central line–associated bloodstream infection. Various designs for the needless<unk>  and its components have been developed over the years. This includes a patent developed by Karl Leinsing for<unk> " which relates generally to<unk> s of the type used in the handling and administration of parenteral fluids, and more particularly, to a valve mechanism incorporated within such<unk>  for~~enabling a fluid interconnection to be made therewith without the use of a sharp cannula.
