Abstract: A respiratory mask for a medical patient including a shell and a flow coupling is disclosed. The shell includes an upper portion configured to cover a nose of the patient and a lower portion configured to cover a mouth of the patient, where an internal surface of the shell defines an interior volume of the respiratory mask. The flow coupling includes a body, a supply flow passage extending through the flow coupling, a scavenging flow passage extending through the flow coupling, and a septum within the body that separates the supply flow passage from the scavenging flow passage. The supply flow passage and the scavenging flow passage are fluidly coupled to an aperture that extends through the upper portion of the shell, and an aperture extending through the lower portion of the shell, respectively.

Abstract: An endotracheal tube assembly comprises an elongate tube having an outer wall defining an outer surface, the tube defining an elongate central lumen and an elongate suction lumen, and an inflatable cuff attached on a distal end portion of the elongate tube. The elongate tube defines a first suction opening having a normal vector parallel to a tangent to an outer circumference of a transverse cross-section of the outer wall of the tube next to said first suction opening, the first suction opening being in fluid communication with the suction lumen.

Abstract: An endotracheal tube assembly is disclosed. The endotracheal tube assembly includes an elongate tube having an outer wall, and a first connector disposed on the outer wall. The outer wall defines a generally cylindrical elongate central lumen therein, an elongate suction lumen therein, and a first suction lumen aperture therethrough, the first suction lumen aperture being in fluid communication with the elongate suction lumen. The first connector includes a first annular wall disposed within a second annular wall, where the first annular wall and the second annular wall extend away from a longitudinal axis of the elongate tube in a radial direction. An internal surface of the first annular wall defines a first flow passage, and a rim of the first annular wall defines a first connection aperture. The first connection aperture is in fluid communication with the elongate suction lumen through the first flow passage.

Abstract: The present invention provides in some embodiments, an endotracheal tube with subglottic secretion suction and a detachable suction line. The endotracheal tube is an elongate tube having an outer wall defining an elongate central lumen and an elongate suction lumen. An inflatable cuff is attached near a distal end of the elongate tube. The shoulder of the inflatable cuff is inverted in order to increase the diameter of the cuff from its distal end to its proximal end. The endotracheal tube also includes a connector to couple the suction lumen to a source of suction to remove subglottic secretions from the area above the cuff.

A diffuser cap is positioned over the opening to the suction lumen and defines a fluid flow path for secretions into the suction lumen through the opening to the suction lumen.

Abstract: A water dissipation device for removing water vapor or moisture from a breathing circuit is provided, including an upper lid portion, an entry port and an exit port. An outer cover structure extends from the upper lid portion to define an enclosed volume. An inner frame extends from the upper lid portion inside the outer cover structure. The outer cover structure includes a first layer of water or moisture wicking material and a second layer of water vapor breathable medium, and has an inner surface area bounding an inner flow space such that water vapor or moisture can permeate from the inner flow space through the outer cover structure out of device. The device can include an inner cup structure extending from the upper lid portion into the enclosed volume to displace the enclosed volume and define and bound a portion of the inner flow space and compressible volume therein.

Abstract: An embodiment in accordance with the present invention provides a water dissipation device to remove water vapor from a humidified gas traveling through a breathing circuit between a patient and a ventilator, or a ventilator and a patient. The present invention includes a water dissipation device having a housing defining entry and exit ports for coupling to the breathing circuit and a breathable medium permeable to water vapor and impermeable to liquid water bacteria, viruses and other gases enclosed within said housing.

Abstract: A water dissipation device for a breathing circuit is provided, including a bucket-shaped hollow composite structure having walls made of a first inner layer made of water vapor wicking material, and a second outer layer of a water vapor breathable medium surrounding the first inner layer. The device defines a flow space surrounded by the composite structure to provide a superior way of removal of moisture or water vapor from a breathing circuit, due to the greater surface area of flow spaces bounded by a water vapor breathable medium and the use of a water vapor wicking material and relatively long dwell times and flow paths through the device. The result is that when the device is connected to a breathing circuit, rainout or condensation in the breathing tube and collection of water within the breathing circuit is significantly reduced.
