Blood lines for hemodialysis and other blood handling procedures may be reused by placing connectors intermediately along the length of the blood lines so that the lines can be disconnected to separate out reusable portions thereof. Specifically, the bulk of the blood lines used may comprise branchless lengths of tubing which are easily reusable, and may be cleaned and stored along with a dialyzer or similar device by connection to a conventional reuse machine. Also, the connectors on the blood lines which are reused may have first and second sealing surfaces. The first sealing surfaces are used in the connections made to form the blood line in its normal form for use. Then, during cleaning and sterilization for reuse, the reusable connectors can connect first and second lengths of blood lines together making use of a second sealing surface, in which the first sealing surfaces are exposed to cleaning/storing solution to cause cleaning and antibacterial action on the first sealing surfaces.
