Multi-parametric fluid determination systems using complex admittance

摘要

An apparatus, systems, and methods related to determining an identity and a concentration of an intravenous fluid. The apparatus, the systems, and the methods described herein may provide near real-time monitoring and/or determination of an identity of components of the intravenous fluid. A concentration and the identity of all of the components of the intravenous fluid may be identified simultaneously.

1. A method for determining an identity and a concentration of an intravenous fluid by detecting fluid interactions at first and second sensing surfaces, the method comprising:
contacting the first and second sensing surfaces of a sensor of a device for multi-parametric testing of the intravenous fluid to the intravenous fluid; determining a multi-parametric profile from the intravenous fluid, wherein the multi-parametric profile comprises
a first parameter detecting the fluid interactions at the first sensing surface, the first parameter comprising a complex admittance or impedance signal from the intravenous fluid, anda second parameter detecting the fluid interactions at the second sensing surface, wherein the second parameter is independent of the first parameter; comparing the multi-parametric profile to stored expected parameter values to determine an identity and a concentration of one or more components of the intravenous fluid.
