Abstract

A plurality of color sensing sections are attached to a toilet seat so as to test a health state or a fecal occult blood portion every time by capturing the feces surface color during defecation. Before feces which have been excreted from a body sink into a water-seal portion, the circumference of the feces is optically captured to detect the color of the surface of the feces. By monitoring changes in color, the health state of the defecator is monitored. In particular, by checking the presence/absence of an occult blood portion, the present invention assists in early detection of colorectal cancer and allows a fecal occult blood test to be performed in a hygienic manner without burdening the user.

Abstract

A biological information measurement system according to an embodiment of the present invention measures biological information of a user of a bathroom on the basis of fecal gas discharged into the bowl of a toilet installed in the bathroom. The biological information measurement system has: a gas flow passage for suctioning and allowing the passage of gaseous matter inside the bowl where the fecal gas has been discharged by the user of the bathroom; and a sensor sensitive part that reacts with the gas contained in the gaseous matter passing through the gas flow passage. The gas flow passage includes a main flow passage, and a sub-flow passage which is provided to the inside of the main flow passage and through which gaseous matter that has flowed in from the main flow passage passes at a flow rate slower than that of the main flow passage. The sensor sensitive part is disposed to the inside of the sub-flow passage.
