  • a housing having a first and a second chamber;

    a first septum defining a boundary of the first chamber, the first septum being accessible through the housing;

    a second septum defining a boundary of the second chamber;

    a catheter connector for connecting a catheter to the access port;

    a catheter connector conduit in fluid communication with the catheter connector;

    a first fluid pathway fluidly connecting the first chamber and the catheter connector conduit;

    a filter interdisposed along the first fluid pathway so that fluid passing along the first fluid pathway from the first chamber to the catheter connector conduit must pass through the filter;

    a one-way valve interdisposed along the first fluid pathway between the catheter connector conduit and the first chamber, the one-way valve allowing fluid to pass therethrough only in the direction toward the catheter connector conduit; and

    a second fluid pathway fluidly connecting the second chamber and the catheter connector conduit.
