  • Patent number: 12318204
    Abstract: A urine collecting and analyzing apparatus for a toilet, the apparatus including a housing with a seat riser that mounts to the toilet rim and a measurement chamber that extends downwardly into the bowl, a urine collecting basin, a flushing system to clean the apparatus, and a controller for data processing and transmission. The basin has a bowl shape to collect urine for testing and is composed of two side panels or two side panels and a front panel. The panels are moved between a storage position along the housing and a collecting position forming the basin by a motorized mechanism. A transfer tube with a flow rate sensor and pump connects the basin to the measurement chamber. The flushing system feeds water through a flushing tube into the basin through an array of nozzles and cleans the entire surface of the basin.

  • Patent number: 10758169
    Abstract: A urine collecting and analyzing apparatus that mounts on a toilet. The apparatus has a housing that mounts to or is integrated into the rim of the toilet bowl and has an opening for access to the bowl. The housing has a collector compartment and a controller compartment. A collector cup fits under the collector compartment extends over the bowl in a retracted position and in a collecting position. When in the collecting position, the cup captures urine released by a user. The cup is connected to a measurement chamber by a transfer tube. The urine moves through the transfer tube from the cup to the measurement chamber to a predetermined threshold volume and level. A controller in the controller compartment reads sensors and transmits sensor data to a device for storage and display.
