The present application is directed to a toilet that allows the separation of solid and liquid waste. This toilet, when activated, releases a retractable urinal that pivots inside the toilet bowl, covering the water visible in the bowl, allowing liquid waste to flow through the retractable urinal through a flexible hose which connects directly to the drain, avoiding the siphon and without the need to apply a discharge of water. In case that a water discharge is wanted to use in the retractable urinal, it is possible, and it is a significantly less amount than that used for solid waste, as it is only the discharge of water necessary to wash the walls of the retractable urinal, and not the 4.2 liters needed to activate the toilet siphon.

A water-saving accessory for a toilet includes a basin, a three-port valve, and first and second lengths of tubing. The basin has inlet and outlet ports and is configured to be coupled to the toilet bowl or toilet seat. The valve is configured to be coupled to a fluid supply line. The first length of tubing is configured to be attached at a first end to the valve and at a second end to the basin inlet port. The second length of tubing is configured to be attached at a first end to the basin outlet port. The valve can be configured to be coupled to a flush line for the toilet bowl such that fluid is normally supplied from the fluid supply line to the flush line, and to be actuatable to divert fluid from the fluid supply line to the first length of tubing.

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.

A toilet modified for disposal of dialysis waste includes a base, a bowl, a water supply port, and a dialysis drain port. In the dialysis drain port is an air gap device that establishes a gap between ends of first and second drain tubes of a dialysis machine and a fluid level in the air gap. RO water and effluent from the dialysis machine enter the chamber of the air gap and mix, before being passed along a path from the dialysis drain port to the bowl of the toilet, where it can be dispelled in a sanitary manner in compliant with all pertinent codes and regulations.

The present disclosure describes a method of detecting a drug marker in a urine sample. The drug markers are fluorophores each of which emits a unique fluorescence spectrum. Accordingly, the method does not detect the drug but rather, the drug marker. The drug marker may include quantum dots which may be functionalized by connecting the quantum dot to a biomolecule. The biomolecule may be cleavable by a peptidase, a protease, or a nuclease to release the drug. Alternatively, the composition may include a liposome carrier. A user who has consumed the drug composition provides a urine sample. The fluorescence spectrometer screens the urine for drug markers based on their unique fluorescent spectra.

A sink applied to a system for recovering and reusing graywater includes a sink body, including a water basin located at an upper part of the sink body and a cavity located at a lower part of the sink body. The water basin comprises a water outlet configured to be connected to a sewer. The sink also includes a sink graywater recovery pipeline configured to be connected to the water outlet. The sink also includes a washing device configured to be connected to the sink graywater recovery pipeline. The sink also includes a switching device configured to switch between the sewer and the sink graywater recovery pipeline. When the switching device opens the sewer and closes the sink graywater recovery pipeline, the graywater is led into the sewer and discarded. When the switching device opens the sink graywater recovery pipeline and closes the sewer, the graywater is led into the washing device.

A water-saving device that addresses the problem of saving drinking water when using flush toilets, such as in households and in public facilities. The device has a hollow profile of a guiding part, into which a hollow inner profile with a collection container is inserted. The device is not a part of the toilet but can be easily connected to it and used at any time. The device can be used on both the inside and outside of the toilet, for men, women and children.

A rinsing apparatus that is a combination toilet rinsing tub and trash receptacle is provided for rinsing soiled items into a toilet while avoiding splashing or otherwise contaminating the apparatus's user and surrounding areas. The rinsing apparatus includes a rinsing tub having an opening that accesses an interior rinsing space, which are defined by a wall or walls of the rinsing tub. The rinsing tub also includes a drain port located at or near a bottom portion of the rinsing tub, which permits contaminants to drain out of the rinsing tub and into a bowl of a toilet. The rinsing apparatus further includes at least two legs that are useful both for allowing the apparatus to stand in a stable vertical position on a floor and also to sit securely on a rim of a toilet bowl while the apparatus is being used to rinse a soiled item.

An apparatus and method for a toilet which minimizes water usage and that can handle both urine and fecal matter. An ultrasonic vibration cleaner unit is disposed to clean at least one fecal plate which is rotated into a lower part of a toilet bowl containing water. Occasional and periodic flushing of solid fecal matter results in less water usage than utilizing water flushing for cleaning and carrying away of solid fecal matte each time of use.

The present disclosure describes a method of detecting a drug marker in urine a urine sample using a toilet. The drug markers are fluorophores each of which emits a unique fluorescence spectra. Accordingly, the method does not detect the drug but rather, the drug marker. A user who has consumed the drug with its unique drug marker then urinates into the toilet and a urine sample is captured. The toilet includes a mechanism for fluid handling which diverts urine into a fluorescence spectrometer. The fluorescence spectrometer screens the urine for drug markers based on their unique fluorescent spectra. The toilet may include a controller which quantifies the drug marker. The fluorescent spectrometer may detect multiple drug markers in a single urine sample. This method may be used to confirm drug compliance, test for illicit drugs, identify amounts of drugs consumed, and other uses described herein.
