Abstract
A fluid collection and measurement container includes a first wall and a second wall disposed opposite the first wall. The second wall is secured to the first wall and the first wall and the second wall define an expandable volume therebetween. A first electrolytic element is disposed on the first wall and a second electrolytic element is disposed on the second wall. A first terminal is connected to the first electrolytic element and a second terminal is connected to the second electrolytic element.

1-31. (canceled)
A system for modulating and measuring a volume of a fluid medium injected into a patient, the system comprising:
- a power injector for providing automated ejection of the fluid medium;
- a delivery catheter for providing delivery of at least a first portion of the fluid medium into the patient, during use;
- at least two flow controllers selectively and fluidly coupled to the power injector;
- a fluid flow control apparatus fluidly coupled between the power injector, the delivery catheter, and the at least two flow controllers, wherein the fluid flow control apparatus, during use, provides fluid diversion of at least a second portion of the fluid medium, the second portion of the fluid medium being diverted away from the delivery catheter, and wherein an amount of diversion of the second portion of fluid is dependent on a selection of one of the at least two flow controllers, wherein the at least two flow controllers are characterized by applying differing resistances to the second portion of the fluid medium;
- a collection container for receiving the second portion of the fluid medium;
- a first sensor configured to collect data for the derivation of the volume of the fluid medium ejected by the power injector;
- and
- a second sensor configured to measure collect data for the derivation of the volume the amount of the second portion of the fluid medium delivered to the collection container.
