Toilet bowl urine measurement instruments
A toilet with multiple urinalysis instruments is disclosed. Two or more of the optical instruments are able to take simultaneous measurements. Optical instruments may share a common light source. One or more light source may use amplitude modulation. A cleaning jet may be used to clean and dry a surface tension urine slot. An inductive heater may be used to preheat and control urine temperature while testing the urine.
1. A toilet comprising:
a bowl comprising:
a recess configured to trap urine
wherein the recess is in optical communication with a plurality of optical instruments;
wherein the recess is formed by a slit, having an open top, open ends, side walls, and a base; and
wherein the side walls at least partially comprise an optically transparent material and the base at least partially comprises an optically transparent material;
a flush mechanism;
one or more controllers;
programming stored on the one or more controllers instructing the flush mechanism to wait for the plurality of optical instruments to complete a urine measurement before actuating the flush mechanism;
wherein at least two of the plurality of optical instruments share a common light source and provide simultaneous measurements of the trapped urine in the recess; and
wherein the plurality of optical instruments comprises a refractometer, a spectrometer, a glucose polarimeter, and a turbidity detector.
2. The toilet of claim 1 , wherein the plurality of optical instruments includes at least two or more of: a laser scatterometer, a color detector, or a microscope.
3. The toilet of claim 1 , wherein one or more of the plurality of optical instruments comprises an amplitude modulated light source.
4. The toilet of claim 1 , wherein the at least two of the plurality of optical instruments share an amplitude modulated light source.
5. The toilet of claim 1 , wherein the recess comprises a trap region that traps urine via surface tension, the trap region comprising a longitudinal dimension in a longitudinal direction and a transverse dimension in an orthogonal transverse direction, the longitudinal dimension being at least twice the transverse dimension; wherein the longitudinal dimension and the transverse dimension are orthogonal in a horizontal plane.
6. The toilet of claim 1 , wherein the recess comprises a hydrophobic surface coating or a hydrophilic surface coating.
7. The toilet of claim 1 , wherein the recess comprises a temperature sensor.
8. The toilet of claim 7 , wherein the temperature sensor is configured to detect the urine entering the recess and to control a temperature of the recess.
9. The toilet of claim 7 , wherein when the temperature sensor detects a change in temperature at least one of the plurality of optical instruments begins measuring the urine.
10. The toilet of claim 1 , wherein two or more of the plurality of optical instruments share an optical path through the urine.
11. The toilet of claim 1 , further comprising a beam splitter.
12. The toilet of claim 11 , wherein the beam splitter is a polarization beam splitter.
13. The toilet of claim 1 , wherein the one or more controllers are operably connected to one or more of the plurality of optical instruments.
14. The toilet of claim 1 , further comprising a polarization beam splitter and a non-polarization beam splitter located on a common optical axis.
15. The toilet of claim 1 , further comprising a heater in thermal communication with the recess.
16. The toilet of claim 1 , wherein one or more of the plurality of optical instruments are glued to a surface of the bowl.
17. The toilet of claim 1 , wherein the side walls of the recess consist of an optically transparent material.
18. The toilet of claim 1 , wherein the base of the recess consists of an optically transparent material.
19. The toilet of claim 1 further comprising a longitudinal raised barrier wherein the recessed slit orthogonally traverses the barrier.
