[Prior art]
Conventionally, electrocardiograms and respiratory rate measurements of elderly and sick people are usually performed by attaching multiple electrodes to the body or inserting a tube in the nostril, but the monitor is expensive and takes up installation space Therefore, measurement is limited only to critically ill patients. For this reason, the number of cases in which general patients and elderly people at home die each year without being able to notify the nurse or nurse of a sudden change due to a heart disease or cerebral infarction is increasing.
[0003]
[Problems to be solved by the invention]
However, even if the cost of the equipment is reduced, the vital information monitor such as the heart, respiratory function, etc. is not only deprived of freedom of action, but also stressed because it has multiple electrodes and tubes attached directly to the bare skin. It remains as a big burden. Even after being discharged, the pain of restraint is still burned in the brain and it takes time to return to the original life. In addition, when elderly people at home or sick people fall into heart disease or cerebral infarction, the number of cases where they cannot press the emergency button themselves and die is increasing.
[0004]
The present invention performs mental anomaly analysis by reducing the mental burden by the above-mentioned biological information monitor and detecting biological information during sleeping of elderly people and sick persons who are relatively free of physical body without restriction. It is an object of the present invention to provide an unconstrained biometric information detection mat capable of preventing a serious accident by informing a caregiver or nurse of an abnormality with sound or light when an abnormality is judged.
