There is provided a bathtub apparatus capable of satisfactorily detecting an electrocardiographic signal even in a state where water is being discharged into a bathtub by a water discharge device. The present invention is a bathtub apparatus () including a bathtub main body (), a water discharge device () that discharges water toward inside of the bathtub main body and is provided above a first inner wall surface () forming a short side of the bathtub main body, and electrodes () attached to the bathtub main body to detect an electrocardiographic signal of a bathing person, where the electrodes are arranged on an inner wall surface of the bathtub main body, and are arranged closer to the first inner wall surface than a position (P) where water discharged from the water discharge device hits a water surface of the water stored in the bathtub main body.

Bathtub apparatus

A toilet seat device includes a main part, a toilet seat, a load sensor, a controller, and a memory. The toilet seat includes a seating part where a user is seated, and a support leg part supporting a load applied to the seating part. The load sensor is provided in the support leg part and detects the load applied to the support leg part. The controller performs at least a body weight measurement of the user based on a detection result of the load sensor. The controller includes a register mode and a normal-use mode in the body weight measurement. The register mode includes determining an estimated value for estimating the total body weight of the user from the seated load. The normal-use mode includes estimating a load value relating to the total body weight of the user based on the estimated value.

Toilet seat device

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.
