Abstract: A portable respirator as described may include an inflatable bag and a respirator body. The inflatable bag may be arranged to provide air to a patient through a face mask or an endotracheal tube in response to compression/retraction actions applied to the inflatable bag. The respirator body may include a first cover portion and a second cover portion arranged to enclose moving components of the portable respirator and define a substantially circular opening for the inflatable bag to be fitted through, a motor, a pair of levers positioned on opposing sides of the substantially circular opening, and a cam mechanically coupled to the motor and arranged to move the pair of levers in response to a rotation action by the motor such that the pair of levers apply the compression/retraction actions to the inflatable bag fitted through the opening.

Abstract: Technologies are described for providing safe and clean air and to prevent interchange of fluids or particulates between people in social situations through two or more distinct airflows generated and/or directed by various structures. An air safety system may receive pre-sanitized air and push through a guidance structure to create a low-velocity, clean air safe zone that prevents exchange of fluids and particulates within the zone and a high speed air shield to prevent injection of fluids and particulates from outside into the safe zone. The system may accommodate one or more persons in an open space of over a table/desk. A modular air safety system may generate a similar safe zone and air shield horizontally in a smaller scale for one or more people.

Abstract: A one or more plane, variable camshaft is described. The single plane camshaft includes a circular drive plate with two radial drive slots on opposing sides of the center, four arms movably coupled at respective endpoints and arranged in a polar configuration, and a scroll plate to allow adjustable operation of the camshaft. Multiple plane camshafts may include a number of half drive plates arranged around a drive block and secured to a base washer through a scroll block. The variable camshaft may be incorporated into portable, motorized or manual, bag valve mask based resuscitation devices or similar ones.
