1. A modular medical pump system for a drug kit having a flexible delivery tube from a drug container, the modular medical pump system comprising:

  • a controller including;

    (a) an electronic processor holding a first stored program for execution by the electronic processor; and

    (b) a programming station interface for releasably receiving a pump unit for communication of control information to the pump unit as so received based on the execution of the first stored program; and



    at least one pump unit releasably receivable by a connector of the controller, the at least one pump unit including;

    (a) a housing carried by the delivery tube extending therethrough, the housing including a retention element locking at least one of the delivery tube and the drug container to the housing of the pump unit against unauthorized removal;

    (b) an electromechanical pump held by the housing and communicating with the delivery tube in the housing to pump fluid through the delivery tube;

    (c) a pump unit electronic processor held by the housing and communicating with the electromechanical pump and holding a second stored program holding drug information indicating a drug identity and a data log for logging actual delivery of medicament to a patient including an amount delivered and a date of delivery between receiving an activation command and a cease operation signal from the controller; and

    (d) a secure pump unit communications interface within the housing and adapted to be inaccessible by a patient proximate to the housing and exclusive of pushbutton controls exposed at an exterior of the housing, the secure pump unit communication interface receiving the control information from the controller for control of the electromechanical pump when the pump unit is received by the controller;

    wherein the pump unit electronic processor prevents operation of the electromechanical pump after receiving the cease operation signal until new drug information indicating new drug identity and new control information are received by the processor together with a predetermined password; and

    wherein the retention element is adapted to require an unlocking tool to remove the drug kit from the housing.
