<p>A universal ventilation device (UVD) comprising: a) a rigid cylinder (1) having an adjustable volume chamber (2) for containing gas or air to be delivered to a patient whose normal inspiration rate is interrupted or has ceased, wherein said adjustable volume chamber (2) may be adjusted to contain an amount of gas or air that is at least roughly equivalent to the lung tidal volume of the patient; b) a rescuer-controlled expelling means for urging the gas or air from said adjustable volume chamber (2) and into the lungs of a patient via a face-mask (6) or endotracheal tube, wherein said rescuer-controlled expelling means urges said gas or air from said adjustable volume chamber (2) to enter the patient's lungs at a flow rate that is at least roughly matched to the normal inspiratory flow rate of the patient; c) a double one-way patient valve (5) located between said ajustable volume chamber (2) and said face-mask (6) or said endotracheal tube which only allows the air or gas expelled from the adjustable volume chamber (2) to enter the lungs of the patient and which allows gas exhaled by the patient to vent to the atmosphere, but does not allow air or gas exhaled by the patient to enter said adjustable volume chamber (2); and d) a one-way gas or air intake valve (9) connected to said adjustable volume chamber (2) which allows compressed gas or fresh air to enter said adjustable volume chamber (2) when said rescuer-controlled expelling means is not urging air or gas into the lungs of the patient.</p> |
