    摘要： In an inhalation system (1) for inhalation of a dosing aerosol (6′), comprising: a dosing device (6) which delivers the aerosol (6′) a container (2) in which one or more chambers (4, 5) separated from one another and connected together during inhalation by means of one or more valves (8) are provided, with an inlet opening (7) emerging into the first chamber (4), into which opening the dosing device (6) is inserted, with the second chamber (5) having a first passage opening (9) which interacts with the respiratory openings of a human being (20), with the second chamber (5) having a second passage opening (10) that is connected to the surrounding air (15) and through which a positive pressure in the second chamber (5) can escape into the surrounding air (15) during exhalation, a simple and hygienic application of the inhalation arrangement (1) should be guaranteed and the aerosol flow should have a linear and rotating motion induced in it during the inhalation procedure. This is achieved in that the valve (8) is formed from an elastically deformable material, preferably silicone, that the valve (8) has a ring-shaped circumferential collar (21) that is fixed to the container (2), at least one slot-shaped notch (22) is worked into the valve (8) which is configured as a spiral running from inside to outside, that during inhalation, the valve (8) acts as a barrier to the flow of the aerosol (6′) flowing through it, as a result of which a linear motion and a spiral-shaped flow direction (11) along and about the longitudinal axis (3) of the container (2) is imposed on the aerosol (6′), channelling it into a three-dimensional spiral

    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.

    摘要： Intubation devices, systems, and methods in which the risk of leakage of nasopharyngeal secretions, esophageal reflux, and blood is reduced, or eliminated, by means of a backflow pressure gradient that is independent of PEEP. Contemplated configurations include (a) a flexible tube for the controlled delivery of air and other gases to the lungs, (b) distal and proximal inflatable seals that can close the annular space surrounding the tube, (c) means to inflate the seals, and (d) means to deliver gas under pressure to the annular chamber in between the two seals. Further configurations further comprise a processor and sensors, and methods are provided for automated backflow of contaminated fluids.
