Embodiment Construction

[0185] Devices, systems and methods for determining the composition of liquids are described herein. The constituents to be determined may include the identity of one or more constituents in a fluid solution (dilution), and thus may be referred to as identity, and in certain contexts, the identity and concentration of one or more of these constituents . In some variations, all components in the fluid may be determined, including the identity of the fluid (eg, saline, etc.). The systems, methods and devices described herein determine the complex conductance of a liquid under various surface conditions (sequentially or in parallel) and / or at multiple applied frequencies to determine an immittance spectrum that can be used to determine characteristic properties of components System (for convenience, it may be referred to simply as an admittance or impedance spectroscopy system), method and apparatus. In particular, the systems described herein are applicable to liquids of low (...

Abstract

Described herein are devices, systems, and methods for determining the composition of liquids, including the identity of one or more drugs in the liquid, the concentration of the drug, and the type of diluent using immittance spectroscopy. These devices, systems and methods are particularly useful for describing the identity and, in some variations, concentration of one or more components of a medical liquid such as intravenous fluid. In particular, described herein are devices, systems and methods that may operate in low ionic strength diluents. Also described are methods of recognizing complex immittance spectrograph patterns to determine the composition of a liquid by pattern recognition.
