Safety enhanced 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:
- application means including delivery means adapted to deliver a preselected therapeutic agent to a patient with said delivery means having flow control means for controlling the flow of said therapeutic agent from said delivery means, and said application means also including electronic control means for controlling said flow control means with said electronic control means including removable programmable means for establishing a flow profile 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 establishing a then selected flow profile program and programming said program into said programmable means while said programmable means is removed from said application means, said programming means also simulating operation of said delivery means according to said then selected flow profile program.

Abstract
Safety enhanced device and method are disclosed for effecting application of a therapeutic agent. A removable and operationally non-volatile programmable element is used to control operation of a therapeutic agent delivery unit. A computer, operationally independent of the delivery unit, is utilized to establish coded information for programming of the programmable element while removed from the delivery unit. Operation of the delivery unit according to the program then established for the programmable element is simulated at the computer prior to actual programming of the programmable element to insure the integrity of subsequent delivery of the therapeutic agent to a patient by the delivery unit. The programmable element effects independent delivery of therapeutic agents in each of a plurality of channels under the control of the programmable element. The programmable element is programmed to establish a flow profile that is customized for a particular patient during each minute of each day, and patient demand for therapeutic agents can also be accommodated with safeguards being included to assure proper dispensing.

18. A method for effecting application of a therapeutic agent to a patient, said method comprising:
-
establishing parameters for safe application of said therapeutic agent to a patient; providing delivery means adapted to deliver said therapeutic agent to a patient; controlling operation of said delivery means through electronic control means that includes a removable programming element which, when operatively positioned, controls the flow of said therapeutic agent from said delivery means; establishing a flow profile program through computer means and simulating operation of said delivery means through said computer means utilizing said flow profile program; and programmming said programmable element with said flow profile program through said computer means only if said simulation of operation of said delivery means through said computer means indicates that delivery of said therapeutic agent according to said flow profile program can be effected within said parameters. - View Dependent Claims (19, 20, 21, 22)

23. A method for effecting application of a therapeutic agent to a patient, said method comprising:
-
selecting a desired flow profile for a preselected therapeutic agent with respect to a predetermined patient; simulating a preselected operation of delivery of said therapeutic agent to a patient utilizing said selected profile; calculating the results of fluid delivery using said selected flow profile and fluid delivery due to said simulated operation and comparing the same to determined differences therebetween; determining from said simulation operation and said determined comparison differences whether said selected flow profile can be utilized to safely deliver therapeutic agent to a patient using said selected profile; programming a logic cartridge that is operationally non-volatile to thereby provide said flow profile only if it has been determined that said selected profile can be safely utilized; and using said programmed logic cartridge to control flow of said predetermined therapeutic agent to said patient. - View Dependent Claims (25)
