An infectious aerosol capture mask (IACM) includes a face tent coupled to a suction tube adapter. The face tent includes a proximal opening configured to be disposed over the mouth and nose of a patient. The face tent further includes a distal opening with a smaller diameter than the proximal opening. A coupler is configured to secure the suction tube adapter to the distal opening of the face tent. The suction tube adapter includes a suction port configured to be coupled to a suction tube for active capture of infectious aerosol and left unconnected for passive capture of infectious aerosol. A viral filter is disposed between the suction port and the face tent to capture infectious aerosols expelled by the patient. The IACM further includes one or more one-way valves that are configured to permit airflow into the face tent.

A system and method for performing a bronchoscopy. The system may include a bronchoscope, a multi-fluid conduit apparatus, and a switching apparatus. The bronchoscope may include an insertion tube having a distal end, a control section, and a working channel. The multi-fluid conduit apparatus may include a first conduit section operably coupled to a vacuum source, a second conduit section operably coupled to an oxygen source, and a third conduit section operably coupled to the working channel, each of the first and second conduit sections being fluidly coupled to the third conduit section. The switching apparatus may include a valve apparatus operably coupled to each of the first and second conduit sections and an actuator apparatus operably coupled to the valve apparatus. The actuator apparatus may alter the valve apparatus between: (1) a suction supply state; and (2) an oxygen supply state.

Containment units, dry powder inhalers, delivery systems, and methods for the same are disclosed. Exemplary devices are configured to have inlets and outlets which are formed with the containment walls of a containment unit. Air jets formed by the configuration of inlet(s) and outlet(s) inside the containment unit create significant turbulence and deaggregate the powder. Delivery system components downstream of the containment unit may integrate the exiting aerosol plume with a low flow nasal cannula air stream for delivery to a subject.

Described herein is a video laryngoscope apparatus for inspection of an oral cavity region of a patient is disclosed. The video laryngoscope includes an apparatus body, a camera arm unit configured to receive and releasably attach thereto a disposable laryngoscope blade, a light source coupled to the camera arm unit, a communication unit, and a power source. The apparatus body includes a proximal end and a distal end, and the apparatus body is elongate and configured to be hand-held by an operator of the video laryngoscope. The camera arm unit includes a proximal end and a distal end with a camera, and the proximal end of the camera arm unit is connected to the distal end of the apparatus body utilizing an adjustable rotary position linkage member. The communication unit is connected via a linkage device to the proximal end of the apparatus body, and the power source is housed by the apparatus body.

A dry powder inhaler includes a powder storage element configured to hold a powdered medicament and an inlet channel receives, powdered medicament from the powder storage element that is entrained in an airflow. The inlet channel has a first diameter and defines an opening. The inhaler includes a dispersion chamber that receives the airflow and the powdered medicament from the opening. The dispersion chamber has a second diameter. The inhaler includes an actuator housed within the dispersion chamber. The actuator oscillates within the dispersion chamber when exposed to the airflow to deaggregate the powdered medicament entrained by the airflow passing through the dispersion chamber. A ratio between the first diameter and the second diameter is between about 0.40 and 0.60 such that an audible sound is produced as the actuator oscillates. The inhaler includes an outlet channel through which the airflow and powdered medicament exit the inhaler.

The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment.
