Port and valve covers are designed to cover connections on ports, IV’s etc to keep them clean and also prevent kinking around the port. Absorbs potential leakage around the connector. Also if you have long hair stops your hair getting caught in them! They can also be a deterrent from little fingers playing with ports and accidentally opening it. Valve covers have more poppers and are slightly larger than port covers (these have 3) and are advised for catheter valve covers.
