A device which may be used in the treatment of snoring sickness. An air blower supplies high volume air at slightly greater than atmospheric pressure to a flexible tube (2). Such air is communicated via tube (2) through nose piece (3), further through flexible tube (4) and a restrictive air outlet device (9). Communicating with nose piece (3) is a face mask (5) adapted to be sealingly attached to a patient\s nose and providing communication between the patient\s nostrils and the interior of nose piece (3). By varying the restriction of device (9) the air pressure at the region of nose piece (3) and also the patient\s nostrils can be varied.
Apparatus for maintaining continuous positive airway pressure, said apparatus comprising a nose piece shaped to fit over the nose of a user and defining a first chamber; a large bore inlet tube entering into a second chamber attached to said nose piece and in fluid communication with said first cham
Apparatus for maintaining continuous positive airway pressure, said apparatus comprising a nose piece shaped to fit over the nose of a user and defining a first chamber; a large bore inlet tube entering into a second chamber attached to said nose piece and in fluid communication with said first chamber only via at least one orifice interconnecting said chambers, said second chamber having a large bore exit to the atmosphere including continually open resistance means to provide a resistance to the flow of gases through said exit and being located adjacent to said exit; and means to releasably seal said nose piece against the facial skin of said user adjacent to said nose to effect a pressure tight seal of said first chamber; said inlet tube connected to a high volume supply of air to cause a high volume of air to flow through said inlet tube, into said second chamber and out said resistance means, said resistance means causing the pressure within said second chamber to be elevated above, and maintained above, atmospheric pressure, said at least one orifice transmitting said elevated pressure to said first chamber, and the flow of air passing between said second chamber and said first chamber through said orifice being substantially equal to the air inhaled and exhaled by said user via the nose.
