Device and method for effecting application of a therapeutic agent
First Claim
1. A device for effecting application of a therapeutic agent to a patient, said device comprising:
- drive means for controlling delivery of a preselected therapeutic agent to a patient;
electronic means including a removable programmable logic cartridge means providing sole configurable operative memory for said drive means with said logic cartridge means being substantially operationally non-volatile to thereby provide programmable means in a format capable of implementing complex flow profiles of substantial duration to control operation of said drive means when said programmable logic cartridge is programmed and operatively positioned; and
computer means for receiving said removable programmable logic cartridge means and programming said logic cartridge means with a then selected flow profile based upon predetermined parameters of patient need and therapeutic agent capabilities.

Abstract
Device and method are disclosed for effecting application of a therapeutic agent. A removable programmable element is used to control operation of a delivery unit, which unit delivers the therapeutic agent to the patient. The programmable element is programmed, while removed from the delivery unit, by a computer that is operationally independent of the delivery unit to insure the integrity of subsequent delivery of the therapeutic agent to the patient by the delivery unit. The delivery unit requires no microprocessor and can include a plurality of channels for effecting independent delivery of therapeutic agents in each channel under the control of the programmable element. The programmable element is programmed with respect to available protocol informaton, including patient history, needs and tolerances, as well as therapeutic agent parameters, to thereby establish a flow profile that is customized for a particular patient during each moment of each day. Patient demand for therapeutic agents can also be accommodated with safeguards being included to assure proper dispensing of the demanded agents.

8. A device for effecting application of a therapeutic agent to a patient, said device comprising:
-
application means including delivery means adapted to deliver a preselected therapeutic agent to a patient with said delivery means having a controllable element for controlling the flow of said therapeutic agent from said delivery means, and said application means also including electronic means for controlling said controllable element with said electronic means including a removable logic cartridge means providing sole configurable operative memory for said application means with said logic cartridge means being substantially operationally non-volatile to thereby provide programmable means in a format capable of implementing complex flow profiles of substantial duration for said delivery means when said programmable means is programmed and operatively positioned at said application means; and programming means operationally independent of said application means for programming a then selected flow profile into said programmable means while said programmable means is removed from said application means to thereby enhance the integrity of said then selected flow profile during subsequent use while operatively positioned at said application means. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method for effecting application of a therapeutic agent to a patient, said method comprising:
-
providing delivery means adapted to deliver a preselected therapeutic agent to a patient; controlling operation of said delivery means through electronic means that includes a removable logic cartridge that provides sole configurable operative memory for said application means with said logic cartridge being substantially operationally non-volatile to thereby provide a programmable element in a format capable of implementing complex profiles of substantial duration so that said programmable element, when operatively positioned, establishes the flow profile of said delivery means; and pre-programming said programmable element while removed from said delivery means. - View Dependent Claims (19, 20, 21)

22. A method for effecting application of a therapeutic agent to a patient, said method comprising:
-
determining the parameters of flow for a preselected therapeutic agent with respect to a predetermined patient; programming a logic cartridge that provides sole configurable operative memory for said application of said therapeutic agent with said logic cartridge being substantially operationally non-volatile to thereby provide a programmable element in a format capable of implementing complex profiles of substantial duration so that said programmable element establishes a flow profile according to the determined parameters of flow for said preselected therapeutic agent; and using said programmable element to control flow of said predetermined therapeutic agent to said patient. - View Dependent Claims (23, 24, 25, 26)
