Abstract: Devices for facilitating breathing and methods of using and constructing the same. In at least one embodiment of a device for facilitating breathing of the present disclosure, the device comprises a generally cylindrical central portion configured to surround a head of a user, a top portion coupled to a relative upper end of the central portion, a bottom portion coupled to a relative lower end of the central portion, and an access mechanism coupled to or formed as part of the central portion, the access mechanism configured to open to provide access to the head or a face of the user when the user is wearing the device.

Abstract: Self-pressurizing fluid deliver systems and devices and methods of using the same. An exemplary pressurized sterile fluid storage bag system referenced herein includes a foam cavity formed from a rigid, non-conforming material and an elastic, conforming material and containing a resilient open cell or closed cell foam with capabilities to restore form when compressed, an air valve, a fluid cavity formed from said elastic, conforming material on one side and a material which may be rigid and non-conforming or elastic and conforming, and a fluid valve.

Abstract: A respiratory assisting device comprising of an expandable bag which has a bilayer that can be inflated in order to give the bag a rigid and predetermined shape. The bag can then be compressed in order to displace inspiratory gas that is in the inner cavity and deliver it to the patient. The bag includes a one-way valve that passes through the bilayer allowing the inner cavity of the bag to fill with ambient air when the air within the cavity has been expended. The bag portion is connected to an air-tight hollow wall prism shape enclosure via a T-connector piece. This t-shaped connecting piece allows the air to pass through two manifold chambers that attach to another t-shaped connecting piece. One of the manifolds contains a pressure-release valve feature on the outer wall which vents air from the bag to the periphery if pressures within the system exceed a target pressure.
