Abstract
The present invention includes systems and methods for monitoring therapeutic drug concentration in blood by detecting markers, such as odors, upon exhalation by a patient after the drug is taken, wherein such markers result either directly from the drug itself or from an additive combined with the drug. In the case of olfactory markers, the invention preferably utilizes electronic sensor technology, such as the commercial devices referred to as “artificial” or “electronic” noses or tongues, to non-invasively monitor drug levels in blood. The invention further includes a reporting system capable of tracking drug concentrations in blood (remote or proximate locations) and providing the necessary alerts with regarding to ineffective or toxic drug dosages in a patient.

30. A therapeutic drug delivery and monitoring system for delivering an appropriate dosage of the therapeutic drug to a patient:
-
at least one therapeutic drug supply having a controller for controlling the amount of therapeutic drug provided by the supply to the patient;
an expired gas sensor for analyzing the patient'"'"'s breath for the presence and concentration of at least one target marker indicative of therapeutic drug concentrations in the patient'"'"'s bloodstream, and for sending a signal regarding the concentration of the therapeutic drug in the patient'"'"'s bloodstream; and
a system controller connected to the therapeutic drug supply, which receives and analyzes the signal from the sensor and controls the amount of therapeutic drug administered to the patient based on the signal. - View Dependent Claims (31, 32)
