Abstract:
1. An adjustable airway pressure system comprising: a cap including: a substantially hollow conduit having indicia indicative of a plurality of airway pressure values and being adapted to receive and output exhaled gas, the conduit also having a first plurality of screw threads on an exterior surface of the conduit; and an adjust collar circumscribing the conduit and having an interior surface with a second plurality of screw threads, the second plurality of screw threads coupling and being complementary to the first plurality of screw threads such that a rotation of the adjust collar causes the conduit to move in a substantially vertical direction, the conduit adapted to be adjusted to one of a plurality of heights along a continuum from a first height corresponding to a maximum value of the plurality of airway pressure values to a second height corresponding to a minimum value of the plurality of airway pressure values; an adjust knob circumscribing and coupled to the adjust collar such that the adjust collar is rotated upon rotation of the adjust knob; a cap retainer; a canister connector; and a bracket, the cap retainer retaining the conduit and coupling the canister connector and the bracket; and a canister containing liquid and receiving the conduit such that the received exhaled gas is output from the conduit into the liquid.
