  • Device for generating by means of ejector action a continuous positive airway pressure (CPAP) during spontaneous breathing
    Patent number: 5193532
    Abstract: A device for generating by ejector action a continuous positive airway pressure (CPAP), comprising a breathing-channel which at one end opens into the atmosphere and at another end is adapted to be provided with an attachment device to the nose and/or mouth of the patient. An inlet channel is connected with the breathing-channel at a point between its ends for fresh gas, the flow of which may be adjusted to obtain an adjustable positive pressure within the breathing-channel. The breathing channel (10) has a first branch-channel (11) which is connectable to the attachment device and a second branch-channel (12) which opens into the atmosphere, the two branch-channels together forming an acute angle (A) of 30.degree.-50.degree. with each other. The inlet channel (13) is situated in the extension of the first branch-channel (11) and is connected to the second branch-channel (12) in such a manner that the stream of fresh gas is directed mainly co-axially into the first branch-channel, producing an ejector action.
