Patent number: 12078588Abstract: Reusable network of spatially-multiplexed microfluidic channels each including an inlet, an outlet, and a cuvette in-between. Individual channels may operationally share a main or common output channel defining the network output and optionally leading to a disposable storage volume. Alternatively, multiple channels are structured to individually lead to the storage volume. An individual cuvette is dimensioned to substantially prevent the formation of air-bubbles during the fluid sample flow through the cuvette and, therefore, to be fully filled and fully emptied. The overall channel network is configured to spatially lock the fluidic sample by pressing such sample with a second fluid against a closed to substantially immobilize it to prevent drifting due to the change in ambient conditions during the measurement. Thereafter, the fluidic sample is flushed through the now-opened valve with continually-applied pressure of the second fluid.Type: GrantFiled: April 19, 2023Date of Patent: September 3, 2024Assignee: The General Hospital CorporationInventors: Ramin Haghgooie, Kenneth T.

Patent number: 9759649Abstract: Microfluidic cuvettes and a network of multiplexed channels including such cuvettes. The channels operationally share a main output channel defining an output of the network. A microfluidic channel includes an inlet, a cuvette, and an outlet that is coupled into the main output channel. The network is configured to provide a difference in resistances, to the fluid, by the main output channel and by an individual outlet is sufficient to prevent cross-contamination of different cuvettes, thereby operably isolating individual channels from one another. An individual cuvette is adapted to substantially prevent the formation of air-bubbles as part of the fluid flow through the cuvette and, therefore, to be fully filled and fully emptied. A system and method for photometric measurements of multiple fluid samples employing such network of channels.Type: GrantFiled: November 18, 2013Date of Patent: September 12, 2017Assignee: THE GENERAL HOSPITAL CORPORATIONInventors: Ramin Haghgooie, Kenneth T.
