Publication number: 20240138709Abstract: A care system monitoring method for sensing the movement state of a bedridden person is provided. The care system monitoring method includes the following stages. Initial-state information is sensed. A first warning signal is issued to remind the caregiver to perform a movement action on the bedridden person when the time that the bedridden person has been in the initial state exceeds the threshold period. First-state information (which is information that is collected when the bedridden person is in the first state) is sensed after completing the movement action. It is determined whether the bedridden person was moved correctly according to the initial-state information and the first-state information. The first-state information is reset as the initial-state information if it is determined that the bedridden person has been moved correctly. A second warning signal is issued if it is determined that the bedridden person has been moved incorrectly.Type: ApplicationFiled: September 7, 2023Publication date: May 2, 2024Inventors: Cheng-Hsu CHOU, Wei-Chih LIU, Fang-Iy WU
