  • Publication number: 20240398668
    Abstract: A medication assistance device includes a storing member, medicine dispenser, discharge/transport mechanism, pack information reader, pack information management system (PIMS), storing detector, and controller. The storing member stores medicine packs. The medicine dispenser arranges a medicine pack in a position. The discharge/transport mechanism discharges the medicine pack from the storing member to transport to a position of the medicine dispenser. The pack information reader in the discharge/transport mechanism reads medication associated information (MAI) attached to the storing member and/or medicine pack. The PIMS manages the MAI of the medicine pack. The storing detector detects attachment or detachment of the storing member to a device main body. The controller informs the PIMS and causes the pack information reader to read the MAI of the storing member based on a detection signal from the storing detector when the storing member is mounted in the device main body.
