The channels 27a and 28a are cut out by integral molding or post-processing, and are covered with the half body 11a and bonded to form a flow path integrated with the mounting plate 11.

FIG. 5 shows a urine analyzer main body 30 for analyzing, for example, specific gravity of urine formed in a urine collection container 31 having a length, width and depth of about several centimeters. The urine collection container 31 is divided by a partition plate 32 into a defoaming chamber 31a and a prism storage chamber 31b on the inlet side while leaving a narrow flow path. The opposite end of the flexible tube 15c to the rotation connected to the rear end of the urine collection nozzle 15 is connected to the defoaming chamber 31a, and air from the air supply / exhaust port 30a of the prism storage chamber 31b is connected. The bubbles generated in the inhaled urine by the inhalation disappear in the process of moving to the prism storage chamber 31b along the partition plate 32. A tube 4 connected to a water valve 41 is provided at a water inlet 30b of the prism housing chamber 31b.
1a is connected to the opposite end, and its lid 44 has a specific gravity measurement prism 45 and a level sensor 48 prism 4.
The upper end of 8a is mounted and accommodates them.

The level sensor 48 is a well-known sensor. When the level sensor 48 is in contact with air, the incident light from above is totally reflected upward at the upper limit position of urine and the upper limit position of water, and the liquid And a rod-shaped prism 48a having two upper and lower prism surfaces (not shown) that transmit light when contacted with the light-emitting device, and two-channel light-emitting and
It comprises a light receiving unit 48b and a detection circuit for detecting that urine and water have reached the upper limit positions due to disappearance of the reflected light.

The prism 45 is formed of a cylindrical acrylic having a length of about 20 mm, as shown in an enlarged view in FIG.
Inclined planes 45a and 45b and a width 10 parallel to the base plane 45c.
mm of the tip surface 45d. Inclined surface 45a, 4
The surface of 5b is formed as a mirror surface that reflects prismatic light by vapor deposition, for example.

The light emitting section 46 emits a diffused light beam wider than the emission angles indicated by the diffused light paths L1 and L2 around the central light path L3.
When the light is reflected toward the center of 5d and totally reflected on the front end surface 45d, it is reflected on the inclined surface 45b perpendicularly to the base surface 45c, that is, parallel to the optical path at the time of emission. When the light emitted from the diffusion optical paths L1 and L2 is totally reflected, it is further diffused and enters the base surface 45c. In these incident areas, for example, a light receiving section 47 which is a PSD for detecting the width of a light beam is arranged.

The incident angle α1 of the diffused light path L2 which enters the distal end face 45d at a relatively small angle is set to 63.2 °, and at least the lower limit of the urine specific gravity measurement range (specific gravity 1.0)
When the urine having a refractive index of 0, 1.333) exceeds the level of the tip surface 45d, the urine is transmitted. On the other hand, the incident angle α of the diffusion optical path L3
2 is set to 65.0 ° which is a critical angle with respect to the upper limit value so that urine having an upper limit value (specific gravity 1.05, refractive index 1.3496) transmits light. That is, the tip surface 4
In the state where 5d is in contact with air, the diffusion optical paths L1, L2
Is totally reflected with respect to the light incident on the tip end surface 45d in the range of the incident angle range, and becomes transparent as the specific gravity increases with respect to the incident light in the range of the diffusion optical paths L1 and L2 when in contact with the urine. The incident angle range in which light is emitted gradually increases from L2 to L1, and accordingly, as the specific gravity increases, the light receiving unit 47
The area of the incident light beam or the amount of incident light becomes smaller. The light receiving section 47 is provided with a conversion circuit for detecting the width of the incident light beam and converting the detected value to the specific gravity of urine.

The light-emitting / light-receiving portion 48b, the light-emitting portion 46, and the light-receiving portion 47 protrude from the notch 11c of the mounting plate 11, and a detection circuit, a conversion circuit, and the like attached thereto are provided on a substrate (not shown) on the upper side. The light receiving section 47 is
It is also possible to configure to detect the width or area of the incident light beam.

As shown in FIG. 1, the urinalysis apparatus assembled on the panel 10 has a panel holding portion having no parts sandwiched between the toilet body 1 and the toilet seat 2, a urine test result display portion, and a power supply. An operation box (not shown) provided with an operation panel to which a switch, a plurality of ID keys, and the like are attached is installed in the vicinity. In this operation box, ID data, gender, etc. belonging to each ID key are registered in advance. Fluctuations in the height position of the toilet seat 2 due to the interposition of the panel 10 are interpolated by the elastic body 2d on the back surface.

Referring to FIG. 4, the sequence control circuit 9
When the D signal is input, the measuring operation starts, the air compressor 20 is operated, and the direction control valves SV1, SV
2 to perform a switching operation to drive the air cylinder 29 backward,
The urine collection nozzle 15 is advanced. At this time, in response to the gender information in the ID signal, the solenoid valve 29b
, The forward stroke is reduced and moved to a dotted line position below the center position of the toilet seat opening (FIG. 1), and in the case of a male, the forward stroke is increased to a more forward two-dot chain line position. Move.

Further, by switching the direction control valves SV1 and SV2 together with the SV3, the air compressor 20 causes the urine analyzer 30 to draw urine until the level sensor 48 detects a predetermined level. Next, with the directional control valves SV1 to SV3 returned, the air compressor 2
The urine collection nozzle 15 is returned to the standby position by driving the air cylinder 29 forward at 0. The water pump 40 is operated to sprinkle water to the urine collection nozzle 15 by the washing shower 17, and the water valve 41 is operated to inject water into the urine analyzer main body 30 until the level sensor 48 detects a predetermined water level. The direction control valve SV4 is switched, the air compressor 20 is operated for a predetermined time, and drainage is performed by air pressure. The shower cleaning of the urine collection nozzle 15 and the operation of pouring and draining the urine analyzer main body 30 are performed, for example, three times. Lastly, without operating the water valve 41, the water pump 40 is operated to perform only shower cleaning.

The operation of the urine analyzer configured as described above will be described with reference to the flowchart of FIG. When the power switch and the assigned ID key are operated on the operation box, the urine collecting nozzle 15 is driven by the air cylinder 29 to a urine collecting position corresponding to the gender. In a state where urine is discharged to the urine collection port 15a, the air compressor 20 sucks urine into the urine analyzer main body 30, and urine that hits the urine collection port 15a directly and the urine that hits the periphery thereof flows along the surface of the urine collection nozzle 15. It is sucked.
When a predetermined urine level is detected, the inhalation is terminated, the urine collection nozzle 15 is returned to the standby position, and the measurement is started. In the urine analyzer main body 30, the specific gravity of urine is measured in accordance with the width of the light beam incident on the light receiving section 47, and the measurement result is displayed on the operation box. Subsequently, the water pump 40 and the water valve 41 are operated to inject water into the urine analyzer main body 30, and at the same time, the washing shower 17 shower-washes the urine collection nozzle 15. When the water level reaches a predetermined level, shower washing and water injection are stopped, and a drainage operation is performed through the urine collection nozzle 15 for a predetermined time. This nozzle cleaning and water injection are repeated three times, and finally the shower cleaning of the urine collection nozzle 15 is performed for a predetermined time, and the measurement is completed.
