Filed:

Appl. No.:

12/145902

Inventors:

Gary James Roth - Wake Forest NC, US
Daniel Patrick Dwyer - Raleigh NC, US

Assignee:

Teleflex Medical Incorporated - Research Triangle Park NC

International Classification:

B01D 46/00

US Classification:

55486, 55498, 55503, 55504

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.

US Classification:

55498, 55309, 55312, 55314, 55DIG 33, 55DIG 34

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.

US Classification:

12820715, 12820227, 12820524, 12820527, 12820716, 128912

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.

International Classification:

A61M 16/00

US Classification:

12820422, 12820417

Abstract:

A respiratory breathing circuit prevents heat loss and condensation in a flow of humidified air through a conduit from a humidification system to a patient interface, such as a nasal cannula. The circuit directly impedes heat loss or insulates the flow of a humidified gas therein, and provides a heating source inside the circuit along the length of the circuit to prevent net heat loss from the circuit tubing by providing thermal energy and/or insulation to impede convective, conductive, or radiative heat loss by the gas as it flows through the system. A temperature, humidity, or other flow quality measuring probe is disposed at the distal end of the circuit near the patient interface to actively measure a corresponding quality of the humidified gas flow to provide feedback to the system. A pressure relief valve is provided on the circuit to prevent a pressure build-up and/or structural failure.

International Classification:

A61M 16/04

US Classification:

12820216

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.
