[0015]

FIG. 1 is a perspective view best showing an embodiment of the present invention, in which an analyzer 1 of the present invention is attached to a toilet 2. Toilet 2 has a toilet seat 4 and a toilet lid 5
A general toilet bowl 3 having a flush tank 6 is provided, and a mattress 7 is laid on the floor. The analysis device 1 of the present invention comprises a urine sampling means 8 for collecting urine excreted by a user seated on a toilet seat, a device body 9, a sub-tank 10 and each carrier tube 1 communicating these devices.
It is composed of 1a to 11c. Each of the transfer tubes 11a to 11c is made of a flexible resin.

FIG. 2 is a perspective view of the apparatus body 9. The device body 9 of the present invention has a substantially rectangular cross section, preferably a D-shaped cross section, and has side surfaces of the long sides 12a and 12b and a short side 13.
The side surfaces of a and 13b are provided. A lid 15 rotatably supported by a hinge 14 is provided on the top of the apparatus 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 lid 15.
7 is provided. At the lower part of the device body 9, there are provided a carrier tube attachment port 18a for taking the collected urine into the device body 9 and a carrier tube attachment port 18b for taking the washing water into the device body 9.

FIG. 3 is a top view of the apparatus main body 9 with the lid 15 opened, and in this state, the replenishment of the carrier liquid and the calibration liquid, which will be described later, can be performed by opening the respective caps 19 and 20. ing. Further, the sensor cell 21 can also 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 are provided inside the apparatus main body 9. A calibration liquid tank 25 for storing the liquid and a transport means 26 for dispensing and transporting a required amount of liquid from these devices are incorporated. These devices are fluid-tightly connected by a transfer tube. The above-mentioned analysis means 23 is preferably a biosensor in which a chip carrying an enzyme is built in the sensor cell 21.
Further, it is preferable that the transporting means 26 comprises a syringe pump 27 and a rotary valve 28 having a plurality of ports. Further, the transport means 26 is preferably arranged below the carrier liquid tank 22 and the calibration liquid tank 25. On the back surface of the lid 15, an operation unit 16, a display unit 17, and a control board 29 that is electrically connected to other devices and controls a series of operations are provided.

When arranging the apparatus main body 9, the long side 12
Either one of a and 12b is arranged so that the side surface of the long side 12a, which is preferably a curved surface, is substantially parallel to the front-back direction of the toilet bowl. In order to ensure the stability of the apparatus main body 9, it is preferable to arrange the side surface of the long side 12b close to the wall surface of the toilet 2. Although it is appropriate to place it at the rear of the toilet bowl as a position that does not interfere with the user, if it is too rearward, it will be difficult to operate when using it, 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 installed in the rim portion of the toilet bowl 3 or the toilet seat 4 in a detachable manner, and moves in the ball space by a driving means (not shown) to collect urine excreted by the user. The collected urine is syringe pump 2
When 7 is driven, it is sent into the cylinder of the syringe pump 27 via the carrier tube 11a and the carrier tube attachment port 18a. Here, a fixed amount of urine is measured, and the rotary valve 28 is rotated to feed the urine to the sensor cell 21. When the amount of urine sent to the sensor cell 21 is very small and it is difficult to reach the sensor cell 21 with only this amount, the rotary valve 28 is once rotated to connect it to the carrier liquid tank 22, and after sucking a necessary amount of carrier liquid, Urine is sent to the sensor cell 21 by utilizing it. A biochemical reaction with urine occurs in the sensor cell 21, and this is analyzed by a program incorporated in the control substrate 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 urine are discarded in the toilet 3 by the urine sampling means 8. Since the analyzer 1 of the present invention is provided with the sub-tank 10 which is connected to the faucet of the flush tank by the transfer tube 11c and stores the flush water,
The washing water is sent to the urine sampling means 8 through the transport tube 11b and the transport tube mounting port 18b by driving the pump 30 provided inside the apparatus main body 9 to complete the washing.
The syringe pump 27 and the rotary valve 28 are washed several times with a carrier liquid or washing water. When the washing process is completed, the urine sampling means is moved to the standby position to wait for the next analysis.

Although specific embodiments of the present invention have been described above, the present invention is not limited to these. For example, if a solenoid valve is provided by branching from a water pipe as a method for taking in washing water. Sub tank 10 and pump 30
Can be omitted, and considering the layout of the entrance and exit of the toilet,
Various design changes can be made such that it can be attached to both a and 13b.

[0023]

As described above, according to the present invention, the analyzer can be installed even in a toilet where the toilet bowl has a little space left and right, and it is possible to provide the analyzer which a seated user can easily operate. It is a thing. As a result, a synergistic effect of not giving a feeling of pressure to the user has appeared. Further, in a preferred embodiment, it is possible to provide a highly accurate analysis with a small sampling amount, and it is possible to provide an analysis device and an analysis device in which replenishment of various liquids is easy even when used over time.
