A canister for use with a medical suction or aspiration device has a first fluid chamber and a second fluid chamber. The first fluid chamber has an inlet. The second fluid chamber has an outlet port. A splash baffle is disposed between the first fluid chamber and the second fluid chamber. The splash baffle has an aperture formed therethrough to allow for fluid flow from the first fluid chamber to the second fluid chamber. An absorbent valve having voids is disposed within the second fluid chamber and engages a portion of the outlet port. The absorbent valve restricting fluid permeability upon contact with fluid from the first fluid chamber to restrict fluid flow through the outlet port.

A vacuum regulator has a vacuum range controller and a manifold including an inlet opening, a vacuum source connection, and a bleed orifice. The vacuum range controller includes a regulator stem having a metering tip, a stem body, and an adjustment rod. The metering tip is selectively positioned against the bleed orifice. The vacuum range controller further includes a vacuum adjuster having an adjustment collar and a resilient member which are coaxially disposed on a portion of the regulator stem. An adjustment knob engages the adjustment rod for concurrent rotational movement therewith.

Vacuum regulator having selectable adjustment ranges

A medicament nebulizer in which a liquid medicament is drawn through capillary flow along a bell shaped path to an annular medicament orifice. Pressurized atomization air is discharged from an orifice and is directed against a deflector which causes the air to flow with a swirling turbulence over one or more medicament orifices. The atomization air aspirates medicament from the medicament orifice and atomizes the medicament. The turbulent swirling flow of the atomization air decreases the average size of the droplets in the resulting aerosol. The flow path of the aerosol through an aerosol chamber to a mouthpiece may rapidly change directions to facilitate condensation of any large droplets in the aerosol. Alternately, a swirling or spiral flow direction may be imparted to the aerosol as it passes through the aerosol chamber to cause any larger droplets to contact and condense on the walls of the chamber.
