摘要：
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. The second t-connector piece has a two-way valve system within its walls to deliver the inspiratory air from the bag to inflate the patient's lungs while preventing exhaled air from the patient from entering back into the bag. Instead this expiratory air is vented into the periphery. Below the valve is a protective filter which serves as a safety mechanism to prevent the transmittance of any potentially dislodged components from within the device from being transferred down into the victim's airway. The air finally flows through a collapsible mask which can be inflated when needed to give it a rigid shape that conforms to the patient's face with the purpose of delivering and receiving rescue breaths. The t-shaped connector pieces are rotatable which permits the two inflatable portions of the device,the bag and the mask, to fold into the interior of section of the manifold enclosure for storage and transportation purposes.
