ABSTRACT:
A liquid measurement device having a containment structure, a sensor, and an interface device, having particular applicability to the collection and administration of electrically conductive fluids. The device is configured to house and monitor the height of a fluid. The containment structure has at least one variable cross-section portion. The sensor has two cooperating variable resistance sections that account for the variable cross-section of the containment structure. The electrical resistance of the sensor changes as the fluid height changes and shorts out a portion of the sensor. The sensor may include an electrically conductive ink that is printed on the interior of the containment structure. The sensor receives an electrical measurement signal and modifies the signal in a predetermined manner to reflect the amount of fluid within the containment structure. The device is useful in measuring the amount of fluid in urine collection bags and intravenous bags.
