  • Publication number: 20250134774
    Abstract: A medication support apparatus includes a container to store medicine packs, a pickup device including a suction device to pick up specific one of the medicine packs from the container, and a suction-device guide to change a posture of the suction device, a conveyor to move the pickup device, and processing circuitry configured to control an operation to pick up the medicine pack by the pickup device. When the suction device fails to pick up the medicine pack at a first pickup position indicating a certain amount of rise of the suction device relative to the medicine packs in the container, the processing circuitry controls the suction device to pick up the medicine pack at a second pickup position indicating another amount of rise of the suction device greater than the certain amount of rise of the suction device at the first pickup position.

  • 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.
