US Patent 7806852 Method and apparatus for patient-controlled medical therapeutics

An apparatus and associated methods are provided to authenticate a patient based on a biometric identifier of the patient before a prescribed dose of medical therapeutic, such as analgesics or other medication, are dispensed to the patient. Authentication takes places by pressing a button and scanning the patient's fingerprint and recording data corresponding to the fingerprint into memory. To receive the medical therapeutic, the patient can have his or her fingerprint read and compared to the stored fingerprint. If there is a match and the programmed limitations are met (e.g., a time interval has elapsed since the last dose), then the medical therapeutic is automatically dispensed to the patient. The system may be integrated with a new patient-controlled medical therapeutic device or the system may be added to an already existing device. Other features and advantages of the example embodiments are described.
