Abstract: A nasal spray device can include housing having a sensor and a nozzle having a housing interface with a graphical image thereon. The sensor can be configured to sense movement of the graphical image when the nozzle moves relative to the housing, for instance during administration of medicine from the nasal spray device. The sensor can include an infrared proximity sensor that senses infrared reflectivity from the graphical image. The infrared proximity sensor can also be used to measure distance to a surface of a vial within the housing to thereby detect insertion of the vial into the housing.

Abstract: A securable and trackable pill dispenser assembly, a system for tracking and administering medication with the pill dispenser assembly, and related methods are presented herein. The pill dispenser assembly can include a tamper resistant cartridge and a smart pill dispensing portion. The pill dispensing portion of the pill dispenser assembly can be configured to authenticate a patient to the pill dispenser assembly and dispense medication according to a prescription accessible to the dispenser portion. The patient may be able to separate the cartridge from the dispenser portion at the end of a prescription period and mate a new cartridge to the dispenser portion for a new prescription period. The cartridge can be filled by a dispensing pharmacy and/or a pharmaceutical partner and delivered to the patient. The cartridge can inhibit extraction of medication when not mated to the dispensing portion.
