Abstract
A disposable breathing assistance device with manometer for monitoring the pressure within the device is capable of providing CPAP and in some embodiments includes a deflection face to prevent injected jets of supplementary respirable gas from directly striking the patient's mucosa. The breathing assistance device further optionally includes a safety pressure relief valve as an additional safety against overpressure within the device. A specialized supplementary respirable gas inlet provides improved pressure characteristics.
Claims15
A disposable breathing assistance device comprising:
- a conduit having a distal end and a proximal end and a main channel extending therebetween, said distal end of said conduit either adapted to be engaged directly with a patient's breathing tract or adapted to be engaged indirectly with a patient's breathing tract, said proximal end of said conduit in fluid communication with the ambient atmosphere;
- a side port, said side port adapted to be supplied with supplementary respirable gas by a respirable gas source and for injecting supplementary respirable gas into an interior of said conduit;
- a manometer affixed to the conduit and in fluid communication with the interior of said conduit;
- a supplementary respirable gas distribution ring adapted to be supplied with the supplementary respirable gas from the side port, the distribution ring adapted to supply the supplementary respirable gas to one or more of supplementary respirable gas inlets, the one or more of supplementary respirable gas inlets delivering the supplementary respirable gas into the main channel;
- wherein each of the one or more of supplementary respirable gas inlets has a substantially rectangular cross section and the cross-sectional height of each of the one or more of supplementary respirable gas inlets has a first height at an end of the of the supplementary respirable gas inlets closest to the side port and a height of each of the one or more of supplementary respirable gas inlets linearly increases towards the main channel.

A disposable CPAP device comprising:
- a conduit having a distal end and a proximal end and a main channel extending therebetween, said distal end of said conduit adapted to be engaged either directly or indirectly with a patient's breathing tract, said proximal end of said conduit in fluid communication with the ambient atmosphere;
- a side port, said side port adapted to be supplied with a supplementary respirable gas for injecting the supplementary respirable gas into an interior of said conduit;
- and
- a supplementary respirable gas distribution ring adapted to be supplied with supplementary respirable gas from the side port, the supplementary respirable gas distribution ring having one or more of supplementary respirable gas inlets, the supplementary respirable gas flows from the side port, through the one or more of supplementary respirable gas inlets and into the main channel, each of the one or more of supplementary respirable gas inlets has a substantially rectangular cross section and the cross-sectional area of each of the one or more of supplementary respirable gas inlets has a first area at an end of the one or more of supplementary respirable gas inlets closest to the side port and a second area at a point distal from the side port, wherein the second area is greater than the first area;
- a manometer affixed to the conduit and in fluid communication with the interior of said conduit for determining a gas pressure within said main channel.

A disposable breathing assistance device comprising:
- a conduit having a distal end and a proximal end and a main channel extending therebetween, said distal end of said conduit either adapted to be engaged directly or indirectly with a patient's breathing tract, said main channel of said conduit in fluid communication with the ambient atmosphere through said proximal end;
- at least one supplementary respirable gas inlet injecting a supplementary respirable gas into said main channel, said at least one supplementary respirable gas inlet adapted to be supplied with supplementary respirable gas from a respirable gas source;
- each of the at least one supplementary respirable gas inlet having a substantially rectangular cross section and the cross-sectional height of each of the at least one supplementary respirable gas inlet having a first height at an end of the of the at least one supplementary respirable gas inlet closest to the respirable gas source and a second height at a point closest to the main channel, wherein the second height is greater than the first height;
- and
- a manometer affixed to the conduit and in fluid communication with an interior of said conduit.
