Toilet for Analysis of Settled Urine

1 . An analytical toilet comprising:

a bowl for receiving excreta from a user;

a urine collection chamber in fluid communication with the bowl;

a sensor for detecting properties of the urine after at least partial settling of the urine;

a valve adapted to release the captured urine from the urine collection chamber; and

a source of flush water to clean the urine collection chamber.

2 . The analytical toilet of claim 1 , wherein at least a portion of the urine collection chamber is transparent.

3 . The analytical toilet of claim 1 , wherein the sensor further comprises one or more sensors along the height of the urine collection chamber are adapted to detect properties of different sections of the at least partially settled urine.

4 . The analytical toilet of claim 3 , wherein the one or more sensors measures protein, viral, bacterial, illicit drug, pharmaceutical drug, blood, mucous, fat, chyle, leucocyte, epithelial cell, or sugar content in the urine.

5 . The analytical toilet of claim 3 , wherein the one or more sensors measures the specific gravity, resistivity, pH, density, salinity, or osmolality at different sections of the at least partially settled urine within the urine collection chamber.

6 . The analytical toilet of claim 3 , wherein the one or more sensors spectroscopically measures the properties of different sections of the at least partially settled urine.

7 . The analytical toilet of claim 2 , further comprising an image capturing device and is positioned to capture images through the transparent portion of the urine collection chamber.

8 . The analytical toilet of claim 7 , wherein the image capturing device records the settling of the urine sample in the urine collection chamber over a pre-determined time period.

9 . The analytical toilet of claim 7 , wherein the image capturing device is configured to capture images along the vertical axis of the at least partially settled urine.

10 . The analytical toilet of claim 7 , further comprising additional image capturing devices, wherein the image capturing device and the additional image capturing devices are positioned at different heights along the urine collection chamber to record different sections of the at least partially settled urine.

11 . The analytical toilet of claim 1 , wherein the urine collection chamber further comprises a fluid level sensor device.

12 . The analytical toilet of claim 11 , wherein the fluid level sensor is used to measure the volume of urine added to the urine collection chamber and the rate at which urine is added to the sample collection chamber during a urination event by a user to thereby determine a urination profile.

13 . The analytical toilet of claim 1 , further comprising an ion detection device, variable light path spectroscopic analysis system, electrodes, or a drawing port.

14 . The analytical toilet of claim 1 , further comprising a filter to prevent feces from entering the urine collection chamber.

15 . The analytical toilet of claim 1 , further comprising an overflow path for urine exceeding the volume of the urine collection chamber.

16 . The analytical toilet of claim 1 , further comprising a heating element to drive off water and concentrate the urine sample.

17 . The analytical toilet of claim 16 , wherein the heating element is a resistive coil, IR heater, or a hot stage.

18 . The analytical toilet of claim 1 , further comprising a reagent dispensing device to dispense one or more reagents into the urine collection chamber.

19 . The analytical toilet of claim 18 , wherein the reagent dispensing device is a microfluidic, capillary, diaphragm, piston, screw, rotary, or peristaltic dispensing device.

20 . The analytical toilet of claim 18 , wherein the one or more reagents comprises a buffer solution, sulfosalicylic acid, CuSO 4 , Benedict's reagent, sodium nitroprusside, or acetic acid.
