Nuwellis Gets U.S. Patent for Blood Filtering Machine and Methods

Nuwellis has received a U.S. patent for its blood filtering system design and methods.

The medical technology company said Tuesday the patent covers methods for improving the accuracy of fluid balance calculations by incorporating the density of replacement fluids and effluent.

Most continuous renal replacement therapy systems assume a default fluid density, but actual fluid densities vary. If left uncorrected, that discrepancy can lead to clinically relevant fluid balance errors, the company said.

Nuwellis's design enables systems to account for density via user input, machine measurement, or derived data for more accurate volumetric flow tracking, the company said.
