Publication number: 20240071590Abstract: The medicine intake support device includes a processing circuitry and a memory. The processing circuitry acquires a previous medicine intake time and a next scheduled medicine intake time, wherein the previous medicine intake time is a time when a patient previously took a prescription medicine, and the next scheduled medicine intake time is a predetermined time when the patient will take a next dose of the prescription medicine. The memory stores a type of the prescription medicine and a measure in response to the patient's failure to take the type of the prescription medicine in correspondence with each other. If the patient failed to take the prescription medicine, the processing circuitry suggests a response method in response to the patient's failure to take the prescription medicine based on the measure stored in the memory, the previous medicine intake time, the next scheduled medicine intake time, and a current time.Type: ApplicationFiled: August 30, 2023Publication date: February 29, 2024Applicant: CANON MEDICAL SYSTEMS CORPORATIONInventors: Mariko SHIBATA, Kohei WATANABE
