Abstract: A supplemental gas delivery device is described for a mask assembly having at least one supplemental gas port, the at least one supplemental gas port including an aperture in communication with an interior of the mask assembly. The mask assembly may include an aperture communicating with an interior of the mask assembly, and a cannula for communicating with the supplemental gas port. The cannula is positioned to deliver supplemental gas adjacent to the patient's nares and/or mouth, to increase an efficacy of treatment for the patient by more directly applying the flow of supplemental gas to the patient's nares. An optional bridging portion may be included to provide a connection between supplemental gas port and the cannula.

Abstract: A secure liquid consumption face covering is created for the general public that is flexible so that the user does not need to remove or open a mask when thirsty or hungry to consume liquid. Through a tube attached with connector(s) and lock(s) to the mask and with an optional disposable straw unit, the wearer can drink liquid from any vessel easily without taking the mask off or breaking the seal of the mask around the user's nose and mouth.

Abstract: In an example, a ventilator includes an outer container containing liquid, an inverted container submerged in the liquid to provide inverted container space between a closed top and an inner container liquid level; gas supply line to supply breathing gas to the inverted container space; and inhalation line having an inlet in the inverted container space to provide breathing gas to patient. The inverted container moves upward from a first elevation when the inverted container space reaches a hydrostatic delivery pressure and volume of the inverted container space increases. The inverted container stops moving upward and the gas supply line stops supplying when the inverted container reaches a second elevation above the first. Based on a breath demand signal or preset timing, the inhalation line opens to permit flow of breathing gas to the patient at the hydrostatic delivery pressure, lowering the inverted container due to lost buoyancy resulting in sinkage.

Abstract: A patient interface includes a first body that rests on a first portion of a patient's face, a second body that rests on a second portion of the patient's face, and a bridge linking the first and second bodies.

The complementary fixation structure can be configured to assist in retaining a feeding tube in position relative to the patient's face or to the patient interface.

Abstract: A flat mounting plate frictionally engages a protective facemask body inner surface, surrounds a first opening, at least partially, and defines a second opening that is co-extensive with the first opening, at least partially. A flat retaining plate frictionally engages the protective facemask body outer surface, surrounds the first opening, at least partially, and defines a third opening that is co-extensive with the first opening, at least partially. A tubular spacer is positioned between the flat mounting plate and the flat retaining plate inserted into the first opening to define a passageway connecting the second opening to the third opening for nourishment to flow therethrough. A gasket is positioned between the flat mounting plate and the flat retaining plate to seal the passageway. The flat mounting plate and the flat retaining plate define jaws for gripping the protective facemask body to hold the port assembly in place.

Abstract: A protective mask having a valve assembly that allow a user to drink a beverage while wearing the mask to maintain a safe environment by filtering contaminants, such as pathogens and particles from passing through the mask.

Abstract: A nasal cannula allows insertion of an upper endoscopy probe, a transesophageal echo probe for exams, or the like. Currently, a nasal cannula is used to measure expired carbon dioxide and deliver oxygen to sedated patients undergoing these procedures. Use of a face mask, such as a non-rebreathing face mask, during these procedures allows increased delivery of oxygen in patients with compromised respiratory function. A side port can be cut into the non-rebreathing face mask to allow insertion of the probes into patient's mouths while allowing delivery of a higher oxygen concentration. The facemask has the ability to easily separate from the nasal cannula, providing for continued use of the nasal cannula during, for example, a recovery period from sedation.
