Programmable dose control module
First Claim
1. A dose control module for controlling dosage rates of at least one treatment solution, the dose control module comprising:
- in an implantable housing separate from a treatment solution reservoir;
a processor for interpreting instructions;
a set of prescription parameters;
a first set of instructions, interpretable by the processor, for implementing a prescription in accordance with the prescription parameters;
a second set of instructions, interpretable by the processor, for interpreting a second signal from a valve, wherein the second signal is indicative of an external magnetic field; and
a control circuitry for generating a first signal, the processor directing the control circuitry, the signal controlling flow rate.

Abstract
The invention is directed to a dose control module for manipulating the dosage of one or more pharmaceutical solutions emanating from an implantable drug infusion pump. The dose control module has a processor and other circuitry for manipulating flow valves and other dose manipulators. Effluent catheters from one or more implantable drug infusion pumps may be connected to the dose control module. The dose control module may direct the effluent pharmaceutical solution to one or more catheters. These catheters direct the pharmaceutical solutions to treatment locations. The invention is also directed to induction coil valves for use in or with the dose control module. The use of induction coils permits the dose control module to determine valve position and counteract large directional magnetic fields produced by MRIs.

10. A dose control system for controlling dosage rates of at least one treatment solution to a patient, the dose control system comprising:
-
at least one treatment solution reservoir; a set of prescribed dosage rates; a dose control module located in an implantable housing separate from the at least one treatment solution reservoir, comprising; a processor for interpreting at least one set of instructions; a time keeping mechanism; a communications circuitry; a set of prescription parameters; a first set of instructions, interpretable by the processor, for implementing a prescription in accordance with the set of prescription parameters; a second set of instructions, interpretable by the processor, for interpreting a second signal from a valve, wherein the second signal is indicative of an external magnetic field; and a control circuitry for generating a signal, the processor directing the control circuitry, the signal controlling flow rate; and a patient control unit accessible by the patient, the patient control unit selectively communicating with the dose control module through the communications circuitry, the patient control unit permitting the patient to select the prescription from the set of prescribed dosage rates. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
