Abstract

Sleep scan, a mattress-type sleep monitor developed a few years ago, is a device that is placed under bedclothes to detect body movements of the user to measure the user’s sleep state. As the measured data is to be transmitted via the Internet, the user does not need to operate the device. Data is measured non-invasively without restraining the user in a certain position, which allows long-term continuous measurements of data. We focused on these specific properties of this device and installed 20 sleep monitors in a special nursing home in A prefecture. In this report, we discuss technical problems associated with the installation of this device and the resulting burden imposed on the facility and target users and introduced measures to deal with these issues. The device failed to record data in 61 cases of a total of 481 cases ; it was possible to collect data on the user’s sleep state in over 87% of all cases. The most common causes of record error were as follows : disconnection of the power cable and communication error in data transmission. No issues such as burden with regard to the installation of the device and/or the measurement have arisen thus far. Therefore, it was confirmed that it is possible to measure the sleep state of elderly people living in nursing homes with this device on a long-term basis.
