The present invention includes methods and devices for providing safeguards to the access of certain substances. Some implementations provide alerts and/or other appropriate actions when substances are subject to spoilage or expiration. Some implementations provide responses to potentially dangerous combinations of substances. Other aspects of the invention involve determining the allergies of a user and providing a warning when allergens are, or recently have been, present. One preferred embodiment provides a smart medicine cabinet for helping to provide medication safely to a patient and to provide other related services.
An ingestible dosage form includes a pill containing a pharmaceutical content and an RF tag associated with the pill. The RF tag is configured to output a wireless response signal in response to a wireless excitation signal received by the RF tag from an RF reader. The ingestible dosage form includes memory for storing pill identifying information. The wireless response signal includes the pill identifying information which may be received and processed by the RF reader. A system for monitoring patient medicine intake compliance includes a monitoring device placed within communicative proximity of ingestible dosage forms to transmit the wireless excitation signal and receive the wireless response signal including pill identifying information from the ingestible dosage forms. A device for determining an identity of a pill and quantity thereof ingested by an individual includes a nasogastric/orogastric tube having an RF tag reader attached thereto for detecting RF tagged pills.
