1. An apparatus comprising:

  • a fluid inlet configured to couple to an outlet of a manually administrable fluid source having fluid source information encoded thereon;

    a fluid outlet configured to deliver fluid from the manually administrable fluid source to a fluid line leading to a patient;

    a fluid flow stop disposed between the fluid inlet and the fluid outlet that prevents fluid flow in a first state and permits fluid flow in a second state;

    an identification sensor to detect the fluid source information when the manually administrable fluid source is being coupled or is coupled to the fluid inlet;

    a fluid flow sensor disposed between the fluid inlet and the fluid outlet for measuring a specific value of how much fluid has been delivered from the manually administrable fluid source into the fluid inlet;

    a flow state controller to selectively cause the fluid flow stop to transition between the first state and the second state automatically in response to the fluid source information being detected by the identification sensor, wherein the flow state controller causes the fluid flow stop to transition from the second state to the first state when a predetermined volume of fluid has been delivered as measured by the fluid flow sensor;

    a housing including a reusable sub-housing and a disposable sub-housing, the disposable sub-housing enveloping at least a portion of each of the fluid inlet, the fluid outlet, and the fluid flow stop, wherein the fluid inlet and the fluid outlet are configured relative to the disposable sub-housing such that they are available for external connections, wherein the disposable sub-housing is operatively coupled to the reusable sub-housing, wherein the reusable sub-housing is intended for use by a plurality of patients and the disposable sub-housing is intended for use by a single patient; and

    a memory within the disposable sub-housing storing a characteristic of a fluid flow path between the fluid inlet and the fluid outlet, a number of fluid inlets, a number of flow control valves, and an arrangement of the flow control valves.
