A respiratory apparatus including an adapter assembly and a catheter assembly. The adapter assembly includes ventilator, respiratory, access, and flush ports. The access port includes a conduit defining a passageway. The flush port projects from the conduit and is fluidly open to the passageway at an outlet. The catheter assembly includes a catheter assembled to a fitting. The fitting includes a hub and a tube, with the tube defining an exterior surface, an interior surface forming a lumen, a circumferential groove in the exterior surface, and a plurality of apertures fluidly open to the lumen and the circumferential groove. The tube is sized to be slidably received within the passageway such that upon final assembly, a fluid pathway is formed between the flush port and a distal end of the catheter via the flush port outlet, the circumferential groove, the plurality of apertures, and the lumen.

An adapter assembly including a manifold and a valve assembly. The valve assembly includes a seat and a valve body having a circular base and a wall. The wall extends from a trailing side of the base to form a dome-like shape terminating at an end at which a slit is formed, with the wall defining opposing sealing edges at the slit. The seat has an upper circumferential surface and a lower circumferential surface. The upper surface engages a leading side of the base, whereas the lower surface engages a trailing side. At least one of the upper and lower surfaces forms a segment of increased height. Upon final assembly, the valve body is disposed across a passageway of the manifold, with the slit providing a selectively openable path. A force imparted by the segment of increased height flexes the base and biases the sealing edges into engagement.

A metered dose inhaler (MDI) spacer has a body that defines a dose receiving chamber. A proximal end portion coupled between the body and a mouth port through which a metered dose may be inhaled by a user of the MDI spacer. A distal end portion is coupled with the body. A combined one-way and flow rate control valve coupled with the distal end portion is configured for permitting external airflow into and prohibiting internal airflow out of the dose receiving chamber. A collar coupled with the distal end portion is configured for receiving an actuator shaft of a metered dose inhaler and for forming a seal about an aerosol nozzle of the metered dose inhaler such that a metered dose of medication is admissible into the dose receiving chamber via the collar while airflow into and out of the dose receiving chamber via the collar is prohibited.

A system for keeping moisture in a vapor phase and for removing particles from a gas is described. The system includes a filter and a heating chamber. The filter is capable of being heated and includes a mechanical element that effectively regulates the heating of the filter. Heat production of the heating chamber is coupled to the proper insertion of the filter into the chamber, such that the filter closes an electrical switch in the heating chamber to allow for the production of heat. An exemplary use of the system is the keeping moisture in a vapor phase and removing pathogenic particles from the exhalation path of a ventilated subject.

A device and method for reducing heat loss in at least one region of a subject's body is described. The device includes a mask component, a heat releasing reservoir, and a conduit connecting the mask component to the heat releasing reservoir and creating an airflow path therethrough, wherein the heat releasing reservoir includes at least one air permeable region that is impermeable to condensed water. Heat loss is reduced by the subject positioning the mask over the mouth and/or nose, positioning the heat releasing reservoir over the region of the subject's body, and passing warmed air exhaled by the subject into the mask through the conduit and into the heat releasing reservoir, such that the warmed air passes through the heat releasing reservoir while retaining condensed water within the heat releasing reservoir, thereby increasing the temperature of the air surrounding the at least one region of the subject's body.

An air flow system cannula is disclosed. The air flow system cannula comprises: a body having a radius of curvature less than about 180 degrees, the body including two solid portions and an adjustable portion provided between the two solid portions for additional flex and angular contouring, two nasal posts, and two end portions. The adjustable portion can collapse to a plurality of positions. The air flow system cannula can also include an adjustable frame that provides additional structural integrity. The adjustable frame is inserted into the body, snap-fit to the body, pressed-fit to the body, or directly molded in the body.

The present invention provides dry powder inhaler (DPI) devices () for dispensing dry powder and methods for using the same. The DPI devices feature vortex mechanisms for directing air in a turbulent manner sufficient to entrain an amount of a dry powder dose for delivery into a user's lungs. The DPI devices feature replaceable dry powder cartridges (). The DPI devices also feature a retractable configuration for storage and for accidental dispensing of dry powder. The DPI devices dispense dry powder in controlled dosages.
