Drug delivery device with sensor for closed-loop operation
First Claim
1. An apparatus to control administration of a drug to the body of a patient, the apparatus comprising:
- a drug infusion device configured to deliver the drug at a predetermined location on the body of the patient;
at least one sensor disposed in the drug infusion device and configured to measure a property related to the patient, wherein the property is a combination of a physiological property related to the patient, a biochemical property related to the patient, including a drug level in the blood of the patient and/or a rate of change of drug level in the blood of the patient, an environmental property related to the patient, including an ambient temperature, and a drug-related property, including quality of the drug being administered;
a controller disposed in the drug infusion device and configured to receive from the at least one sensor data representative of the measured property and further configured to determine a drug delivery rate based on the received data; and
the drug delivery device is further configured to deliver the drug to the body of the patient based on the determined drug delivery rate.

Abstract
An apparatus and a system for controlling and/or managing administration of a drug to a body of a patient. The apparatus includes a drug infusion device configured to deliver drug at a predetermined location in the body of the patient, at least one sensor disposed in the drug infusion device and configured to measure a. corresponding property related to the patient and selected from the group consisting of physiological properties, biochemical properties, environmental properties and drug-related properties, a controller disposed in the drug infusion device and configured to receive from the at least one sensor data representative of the measured corresponding property and based on the received data, determine a drug delivery rate. The drug delivery device is configured to deliver the drug to the body of the patient based on the determined drug delivery rate.

14. A method for controlling administration of a drug to the body of a patient using a drug delivery device having at least one sensor and a controller, the method comprising the steps of:
-
measuring a property related to the patient, wherein the property is a combination of a physiological property related to the patient, a biochemical property related to the patient, including a drug level in the blood of the patient and/or a rate of change of drug level in the blood of the patient, an environmental property related to the patient, including an ambient temperature, and a drug-related property, including quality of the drug being administered; receiving data representative of the measured property; based on the received data, determining a drug delivery rate; and using the determined drug delivery rate, delivering the drug to the body of the patient at a predetermined location on the body of the patient. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. A system for managing or controlling administration of a drug to the body of a patient, comprising:
-
a drug infusion device for administering the drug to a subject at a predetermined location on the subject; a sensor for detecting at least one parameter related to the subject, wherein the parameter is a combination of a physiological parameter related to the patient, a biochemical parameter related to the patient, including a drug level in the blood of the patient and/or a rate of change of drug level in the blood of the patient, an environmental parameter related to the patient, including an ambient temperature, and a parameter related to the drug itself, including quality of the drug being administered; and a controller for controlling the device for administering the drug to the subject in accordance with the at least one parameter. - View Dependent Claims (24, 25, 26)
