Abstract: A fluidic device for a mechanical ventilator has an inlet configured to receive fluid from a pressurized source. The device includes a device nozzle having a device nozzle axis, a device nozzle length, and a device nozzle width. The device includes at least one port having an opening to an environment external of the device. The device is configured so that ambient fluid enters the device through the port and mixes with a source fluid from the inlet to define a diluted fluid mixture. The device is further configured so that the diluted fluid mixture enters the device nozzle.

Abstract: Improved cold seal packaging rollers for packaging machines, as disclosed herein, may be configured to define a turned-up or bend along each edge portion of a packaging created by the packaging machine for avoiding jams of the packaging in automated packing systems. The improved cold seal packaging rollers may be incorporated directly into the cold seal packaging machine, replacing the standard rollers, or external to the machine to manipulate a completed packaging. The improved cold seal packaging rollers may comprise a first gear and a second gear, each having a circumferential toothed portion and a circumferential beveled portion. The circumferential beveled portion of the first gear may be angled inwardly toward a central axis as it moves away from the circumferential toothed portion. The circumferential beveled portion of the second gear may be angled outwardly away from a central axis as it moves away from the circumferential toothed portion.

Abstract: Provided herein are devices and methods that relate to ventilation and respiration. In one embodiment, a ventilator device comprising a fluidic amplifier with one or more coaxially aligned components, where there are no internal moving components. In another embodiment, a device and related methods for treating a patient who needs ventilation such as after infection by the coronavirus Covid-19.
