  • Patent number: 11732229
    Abstract: Fluidic multiwell bioreactors are provided as a microphysiological platform for in vitro investigation of multi-organ crosstalks for an extended period of time of at least weeks and months. The disclosed platform is featured with one or more improvements over existing bioreactors, including on-board pumping for pneumatically driven fluid flow, a redesigned spillway for self-leveling from source to sink, a non-contact built-in fluid level sensing device, precise control on fluid flow profile and partitioning, and facile reconfigurations such as daisy chaining and multilayer stacking. The platform supports the culture of multiple organs in a microphysiological, interacted systems, suitable for a wide range of biomedical applications including systemic toxicity studies and physiology-based pharmacokinetic and pharmacodynamic predictions. A process to fabricate the disclosed bioreactors is also provided.

  • Publication number: 20200368441
    Abstract: A medication delivery device including a drive mechanism, a retraction mechanism and a sensing system. A medication container is movable relative to the medication delivery device between storage and delivery positions. The drive mechanism drives a plunger in a translational movement to move the medication container from the storage position to the delivery position and to dispense medication from the medication container in a dispensing event. The retraction mechanism includes a rotary member that rotates during a retraction movement of the retracting mechanism. The sensing system includes a first sensor to detect operational status and a second sensor to sense rotational movement of the rotary member. A controller is configured to detect initiation of a dispensing event based on signals generated by the first sensor and detect completion of the dispensing event and/or completion of the retraction movement based on signals generated by the second sensor.
