Method and a system for measuring instantaneous inflow rate of urine
The present invention provides a system for measuring instantaneous inflow rate of liquid, comprising: a receptacle, comprising an opening at a top side, a nozzle at a bottom and/or multiple holes on the side section of said receptacle configured to receive the inflow of liquid from said top opening, and simultaneously release said liquid through said nozzles; a sensing device, configured to sense the level of liquid within the receptacle and produce signals indicative of the level of liquid in the receptacle; and a processor, configured to receive said signals, calculate the level of liquid in the receptacle according to said signals; and analyze said calculations, to obtain the instantaneous inflow rate of liquid.
1. A system for measuring inflow rate of liquid comprising:
a receptacle comprising a top portion, a bottom portion, an opening arranged at the top portion, a nozzle arranged at the bottom portion, an inner element comprising an at least partially cylindrical-shaped side wall and a plurality of openings arranged along a perimeter of the at least partially cylindrical-shaped side wall, and a dome-shaped part comprising a side wall and a plurality of openings arranged along a perimeter of the side wall of the dome-shaped part, wherein the receptacle is configured to allow a liquid to flow through the plurality of openings of the dome-shaped part and the plurality of openings of the inner element into an interior of the receptacle and out of said interior through said nozzle;
a sensing device configured to generate one or more signals indicative of a level of the liquid in the interior of the receptacle; and
a processor configured to receive said one or more signals and determine an inflow rate of the liquid based on said one or more signals.
2. The system of claim 1 wherein the nozzle comprises a width that is between 4-7 mm.
3. The system of claim 1 wherein the receptacle further comprises a plurality holes on an outer wall said receptacle.
4. The system of claim 1 further comprising an accelerometer for measuring tilt of the system.
5. The system of claim 1 wherein the dome-shaped part is removable from the at least partially cylindrical-shaped side wall.
6. The system of claim 1 further comprising a bowl configured to be placed over a toilet, the bowl further configured to attach to the receptacle and guide said liquid towards the dome-shaped part of the receptacle.
7. The system of claim 1 wherein the sensing device comprises at least one electrode, and wherein said one or more signals are indicative of at least one of resistance and capacitance of the liquid.
8. The system of claim 1 wherein said nozzle is arranged at a perimeter of an outer wall of the receptacle.
9. The system of claim 1 wherein the receptacle further comprises an outer wall, and wherein said interior is defined between at least a portion of said outer wall and at least a portion of said inner element.
10. The system of claim 1 wherein the receptacle further comprises a sloping floor at the bottom portion.
