Patent number: 9002718Abstract: When the present time of a clock circuit is a medication time recorded in advance in a SD card, a notice that the medication time has come is given by a voice output portion or the like. Presence/absence of a medicine package in each block of a medicine package case is sensed by a medicine package sensor. The time point and the presence/absence of the medicine package are recorded in the SD card. A notice corresponding to the presence/absence is output. At a time except for the medication time, taking-out of the case, opening/closing of the cover, taking-out and return of the medicine package are recorded in the SD card based on detection signals from the medicine package sensor, medicine package case sensor, and case cover opening/closing sensor. A notice corresponding to the sensed situation is output.Type: GrantFiled: February 22, 2006Date of Patent: April 7, 2015Assignees: Omron Healthcare Company Ltd.Inventors: Yutaka Imai, Tomonori Inoue, Kenji Eda, Takahide Tanaka
