The above-mentioned features and effects of the present invention, as well as other features and advantages, will be apparent from the description of the following embodiments.

[0015]

FIG. 1 is a perspective view showing an embodiment of the present invention best, in which an analyzer 1 of the present invention is mounted on a toilet 2. FIG. Toilet 2 has toilet seat 4 and toilet lid 5
A general toilet 3 having a washing tank 6 is provided, and a mattress 7 is laid on the floor. The analyzer 1 of the present invention includes a urine sampling means 8 for collecting urine excreted by a user sitting on a toilet seat, an apparatus main body 9, a sub-tank 10, and each transport tube 1 communicating these devices.
1a to 11c. Each of the transport tubes 11a to 11c is formed of a flexible resin.

FIG. 2 is a perspective view of the apparatus main body 9. The device body 9 of the present invention has a substantially rectangular cross section, preferably a D-shaped cross section, and the side surfaces of the long sides 12a and 12b and the short side 13
a, 13b. A lid 15 rotatably supported by a hinge 14 is provided at an upper portion of the apparatus main body 9. An operation unit 16 for operating the analyzer 1 and a display unit 1 for displaying the progress and results of the analysis are provided on the top of the lid 15.
7 are provided. At the lower part of the apparatus main body 9, a transfer tube mounting port 18a for taking collected urine into the apparatus main body 9 and a transfer tube mounting port 18b for taking washing water into the apparatus main body 9 are provided.

FIG. 3 is a top view of the apparatus main body 9 with the lid 15 opened. In this state, replenishment of a carrier liquid and a calibration liquid, which will be described later, becomes possible by opening the respective caps 19 and 20. ing. Also, the sensor cell 21 can be replaced by being detached.

FIG. 4 is a schematic diagram for explaining the internal structure of the apparatus main body 9. A carrier liquid tank 22 for storing a carrier liquid for transporting urine, an analysis unit 24 including a sensor cell 21 and a sensor holder 24, and a calibration liquid for calibrating the analysis unit inside the apparatus body 9 And a transport means 26 for dispensing and transporting a required amount of liquid from these devices. These devices are connected in a liquid-tight manner by a transfer tube. The aforementioned analysis means 23 is preferably a biosensor incorporating a chip in which an enzyme is carried in the sensor cell 21.
Further, it is preferable that the transfer means 26 be constituted by a syringe pump 27 and a rotary valve 28 having a plurality of ports. Further, it is preferable that the transfer means 26 is disposed below the carrier liquid tank 22 and the calibration liquid tank 25. A control board 29 that is electrically connected to the operation unit 16, the display unit 17, and other devices and controls a series of operations is provided on the back surface of the lid 15.

When arranging the apparatus main body 9, the long side 12
a or 12b is disposed so that the side surface of the long side 12a preferably formed of a curved surface is substantially parallel to the front-rear direction of the toilet. In order to ensure the stability of the apparatus main body 9, it is preferable to arrange the side of the long side 12b close to the wall surface of the toilet 2. As a position that does not disturb the user, it is appropriate to dispose it behind the toilet, but if it is too far behind, the operation becomes difficult in use, so an appropriate position is preferable.

Next, an analysis method using the analyzer of the present invention will be described. The sampling means 8 is incorporated or detachably provided in the rim portion or the toilet seat 4 of the toilet 3, and moves the ball space by a driving means (not shown) to collect urine excreted by the user. Collected urine is syringe pump 2
7 is driven into the cylinder of the syringe pump 27 via the transfer tube 11a and the transfer tube mounting port 18a. Here, a certain amount of urine is measured, and the urine is sent to the sensor cell 21 by rotating the rotary valve 28. When the amount of urine sent to the sensor cell 21 is very small and it is difficult to reach the sensor cell 21 by itself, the rotary valve 28 is once rotated and connected to the carrier liquid tank 22, and a required amount of carrier liquid is sucked. Urine is sent into the sensor cell 21 using the urine. A biochemical reaction with urine occurs in the sensor cell 21, which is analyzed by a program incorporated in the control board in advance, and the concentration and specific gravity are displayed on the display unit 17.

When the display of the analysis result is completed, the collected urine and the carrier liquid contaminated with the urine are discarded into the toilet 3 by the urine sampling means 8.
