Abstract: A finger-controlled combination irrigation and suction device is provided. The device includes a handpiece. The handpiece includes: a shaft having a first end and a second end, and having a channel disposed from the first end of the shaft to the second end of the shaft for allowing suction through the shaft; a nozzle coupled to the first end of the shaft; an inlet disposed through an exterior surface of the shaft and in operable communication with the channel, the inlet being disposed to be manually covered and uncovered by one or more fingers of a single hand of a primary caregiver for control of suction through the shaft; and a conduit having a first end disposed to receive a volume of irrigation solution after one or more fingers of the single hand of the primary caregiver act upon an irrigation source proximate to the conduit.

Abstract: A respiratory circuit apparatus and circuit are provided. The circuit includes: an adapter having a plurality of connectors of two or more different internal or outer diameters; and a pressure release valve configured to emanate sound if a pressure of a gas received at the pressure release valve is greater than or equal to an activation pressure of the pressure release valve. The pressure release valve can have a first end of a body portion coupled with one of the plurality of connectors of the adapter. The pressure release valve can be coupled inline in the respiratory circuit via the adapter and in close proximity to a patient location.

Abstract: An apparatus for providing pressure into which a patient must exhale is provided. The canister has a canister axis and is disposed to hold liquid. The canister also has indicia of pressure on the canister. The apparatus also includes a substantially rigid lid disposed to substantially cover a mouth of the canister and having a first inlet through the lid. The apparatus also includes an adapter in the first inlet. The apparatus also includes a conduit being retained by the adapter such that the conduit is substantially immovable relative to the canister axis.

Abstract: An adjustable airway pressure system is provided. The system may include a cap and a canister. The cap may include a substantially hollow conduit having indicia indicative of a plurality of airway pressure values and adapted to receive and output exhaled gas. The conduit may have screw threads on an exterior surface of the conduit. The cap may also include an adjust collar circumscribing the conduit and having an interior surface with a second plurality of screw threads. The second plurality of screw threads may couple and be 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 may be adapted to be adjusted to heights along a continuum. The canister may contain liquid and receive the conduit such that the received exhaled gas is output from the conduit into the liquid.
