A disposable real-time closed catheter urine output monitoring system. The monitoring system of the invention can measure urine outputs at both high and low urine flow in real time, using a pressure chamber in the form of a hollow body having an input port for coupling to a tube connected to a catheter for collection of urine from a patient, an exit port coupled to a collection container and a vent port, such that air may flow through the vent, but urine is blocked by the vent. A sensor measures flow from the exit port of the pressure chamber into the collection container, and a pressure sensor may be included to measure pressure in the pressure chamber. The invention also provides a method of using the apparatus in a real-time monitoring system.

Real time urine monitoring system

A sensor for detecting a substance in a physical space, having an RF energy emitter fed by a signal source on one side of the space and an RF energy receiving element coupled to a detector at an opposite side of the channel, spaced apart by a distance (r) selected so that when the signal wavelength (&#x3bb;) changes based on the value of the dielectric constant (&#x2208;) of the particular substance in the physical space between the emitter and receiver, the mode of field type within the sensor channel changes between near field and intermediate or far field mode.
