The present technology relates to respirator devices including source control features. In some embodiments, a source control mask device can include a shield that substantially covers the mouth and nose of a user and a mechanism that can actively extract air as it is exhaled by the user. The extracted exhaled air can then be sanitized before the mask device discharges it into the atmosphere. The mask device may selectively form a seal to the user's face dependent on air flow conditions.

A bronchoscopy scope guide (30) for a non-invasive ventilation (NIV) patient interface (10) comprises a semi-rigid scope guide tube (32), a bronchoscopy scope seal (48), and a semi-rigid grommet (34). The semi-rigid scope guide tube (32) includes a principal axis (36) and entrance and exit guide portions (38,40). The bronchoscopy scope seal (48) couples to the scope guide tube for sealing around a bronchoscopy scope when inserted through the scope guide tube. The semi-rigid grommet (34) is disposed about an outer circumference of and flexibly coupled to the scope guide tube (32) and is located in a principal plane (52) transverse to the principal axis of the scope guide tube. The scope guide tube (32) is pivotally manipulate-able about the flexible coupling of the grommet (34) for positioning a distal end (46) of the exit guide portion of the scope guide tube proximate, but not in contact with, one of a nasal cavity or mouth opening of a patient for assisted guidance control of the bronchoscopy scope within an interior region (58) of the patient interface (10) in performance of a bronchoscopy procedure.

A gas-washout vent includes a housing with a first wall with one or more passages through the wall configured to provide fluid communication with a portion of the patient interface system exposed to a therapy pressure. The passages include respective first openings on a first surface of the first wall. The housing at least partially defines a second opening in communication with ambient atmosphere. A diffusing material is located at least partially within the housing to be adjacent the first surface. A surface of the diffusing material facing the first surface is spaced away from the first surface by a gap that extends to provide a fluid communication between all of the first openings and between all of the first openings and the second opening. The housing is configured so that air is prevented from flowing out of the housing at all areas directly opposite each of the first openings.

A stand-alone chamber or multi-chamber inhalation system has at least two alternative vaporized test liquid supply systems for passive or self-administered delivery of vaporized test fluid and air to one or more test chambers, which can be passive or restraint chambers, based on operator selection of delivery on and off times in a passive mode or actuation of an actuator in the chamber by a test animal in a self-administered mode. In one case, a multiple inhalation chamber system has two or more separate test fluid delivery systems and provides options for selective passive uniform drug delivery to multiple chambers or selective delivery of two or more different drugs to different groups of chambers from different delivery systems so that two different drugs or different concentrations of delivered drugs can be tested simultaneously.

An oral appliance for increasing oxygenation including: an upper component configured to fit onto at least a portion of upper teeth of a user and including an upper locking mechanism; and a lower component configured to fit onto at least a portion of lower teeth of the user and including a lower locking mechanism configured to engage the upper locking mechanism in at least one position of the lower component relative to the upper component corresponding to at least one protrusion position of a mandible of the user of 50% of maximum protrusion to set an oxygenation capacity of the user; wherein the upper locking mechanism and the lower locking mechanism are configured to be lockable or unlockable or both by a pressure of a tongue the user or the mandible or both.

A patient airway dome including an adjustable frame having a hinge such that the hinge allows the frame to adjust between an erected position to create an airway dome and a collapsed position that allows the frame to lay flat, a dome covering located over the retractable frame, a plurality of ultraviolet lights operatively connected to the retractable frame, a plurality of superior glove access portals located on the dome covering, a plurality of inferior glove access portals located on the dome covering, an anesthesia circuit tube operatively connected to the dome covering, and an anesthesia machine connector operatively connected to the anesthesia circuit tube.

A customizable mask including a conforming seal is configured to utilize the physical process of granular jamming to enable it to adapt to a wide range of facial geometries. The mask may include a frame having a perimeter and a conduit connection, a conforming seal positioned along the perimeter of the frame. The conforming seal may include a sealing surface and a connecting surface, the connecting surface configured to mate with the perimeter of the frame, and the sealing surface configured to conform to a users' face. The conforming seal may further include an outer casing, granular material contained within the outer casing, and a vacuum connection. The mask may also include a similarly configured conforming frame. Further disclosed are methods of forming such masks.

An instrument for accessing and visualizing hollow organs is provided. The instrument includes a mouthpiece having a perforated mask and a sleeve having a generally cylindrical or ovoid shape extending from the perforated mask substantially perpendicularly thereto and defining a channel. The instrument further includes sucking means having a suction chamber or closed volume that is restrained to the mask on the side where the sleeve is formed. The suction chamber has a plurality of through openings adapted to allow fluid communication with a surrounding environment, an intake opening communicating with the suction chamber formed on the mask, wherein the through openings are formed on the skirt of a dome-shaped member which delimits the suction chamber.
