Biological information measurement system

Abstract

The biological information measurement system of the present invention includes a test subject-side device provided in a toilet installation room, and a server communicable with the test subject-side device, the test subject-side device includes a sulfur-containing gas sensor sensitive to sulfur-containing gas and outputting detection data, a transmitter-receiver transmitting measurement data including detection data of the sulfur-containing gas detected by the sulfur-containing gas sensor to the server, and the server includes a database in which measurement data including detection data of sulfur-containing gas detected by the sulfur-containing gas sensor is accumulated and recorded with dates and times of defecation acts by being associated with test subject identification information, and server-side data analyzer that analyzes physical condition of a test subject on the basis of a time-dependent variation tendency of the measurement data accumulated and recorded in the database.

What is claimed is: 
     
         1 . A biological information measurement system that diagnoses risk of illness of a test subject based on defecation gas discharged in to a bowl of a flush toilet, the biological information measurement system comprising:
 a test subject identification device that accepts an input of a test subject identification information;   a suction device that sucks gas in the bowl into which the defecation gas is discharged by the test subject;   a gas detector provided for exposure to the gases sucked by the suction device, the gas detector comprising a first gas sensor configured to detect an odiferous gas composed of a sulfur component and a second gas sensor configured to detect a healthy-state gas composed of at least one of hydrogen gas, carbon dioxide gas or methane gas, wherein the first gas sensor is configured to output a first detection data, and the second gas sensor is configured to output a second detection data;   a control device that controls the suction device and the gas detector;   a storage device that stores the first detection data and the second detection data acquired by the gas detector with the test subject identification information accepted by the test subject identification device;   a data analyzer that analyzes the risk of illness of the test subject on the basis of a time-dependent variation tendency of the first detection data and the second detection data stored in the storage device; and   an output device that outputs an analysis result by the data analyzer.   
     
     
         2 . The biological information measurement system according to  claim 1 , wherein the data analyzer analyzes a higher risk level of illness of the test subject when the first detection data increases and the second detection data decreases than when the first detection data and the second detection data increase. 
     
     
         3 . The biological information measurement system according to  claim 1 , wherein a pair of the first and second detection data forms a two-index measurement result, wherein the storage device is configured to store a plurality of the two-index measurement results, and wherein the output device is configured to display the plurality of two-index measurement results two-dimensionally on a physical condition display table. 
     
     
         4 . The biological information measurement system according to  claim 3 , wherein the physical condition display table is divided into a plurality of stage areas which represent different physical conditions, and a respective plurality of two-index measurement results is plotted in a stage area. 
     
     
         5 . The biological information measurement system according to  claim 1 , wherein the test subject identification device is configured to output an identify of the test subject in response to selection of the identify by the test subject, wherein the gas detector is configured to output the first and second detection data without waiting for the test subject identification device to output the identity of the test subject, and wherein the data analyzer is programmed to later relate the first and second detection data to the test subject after the test subject identification device outputs the identity of the test subject. 
     
     
         6 . The biological information measurement system according to  claim 3 , wherein the gas detector further comprises a third gas sensor configured to detect a vaporized short-chain fatty acid contained in the defecation gas and output third detection data indicative of an amount of the detected vaporized short-chain fatty acid, and wherein
 the data analyzer is programmed to:
 use the third detection data during the same defecation act, wherein a combination of the first, second and third detection data forms a three-index measurement result; and 
 relate the three-index measurement result to a coordinate of a table that defines a third index scale representing a range of the third detection data.
