Patent number: 9387300Abstract: The invention is directed to a ventilation interface, which includes a cannula having one or more nasal prongs, a ventilation tube connected to the cannula and headgear. The cannula is secured onto the patient through one or more arced couplers positioned between the cannula and headgear. The cannula has a first side wall, a second side wall and a top wall which form a reservoir. The top wall includes a first portion, a second portion and a notch positioned between the first portion and second portion. The ventilation tube includes one or more bleed ports and provides breathable gas to a patient. The headgear includes a first strap and a second strap.

Publication number: 20140311493Abstract: A nasal ventilation interface and method for providing nasal ventilation to a patient includes a hybrid face mask, covering only the mouth, coupled with removable nasal inserts extending from the upper surface of the mask. The nasal interface has modular, removable, and disposable nasal pillows connecting the upper surface of the mouth-portion of the mask to the user's nares. Each part of the hybrid mask is modular and can be formed in various shapes and sizes. The ventilation interface has differing gas line entry ports and can be shallow with a relatively deep soft facial interface or deep with a relatively shallow facial interface. In either case, the upper surface receives the nasal interface. The upper surface can have a removable ceiling in which is defined a nasal interface connector. The nasal interface can be integral with a removable ceiling. The entire hybrid mask can be made in one piece.Type: ApplicationFiled: May 12, 2014Publication date: October 23, 2014Applicant: RESPCARE, INC.Inventors: Sanjay Chandran, Louis Javier Collazo

Patent number: 8814838Abstract: A novel and non-obvious apparatus, system, and method for managing respiratory secretions and fluids in sections of artificial airways. In an embodiment of the invention, a respiratory secretion retention (RSR) device configured to connect to an artificial airway can be provided. The respiratory secretion retention (RSR) device can include a housing that defines a passageway for the flow of respiratory gases, a chamber that is defined by the housing, where a portion of the chamber is configured to retain exhaled respiratory particulate and liquid, and at least one element configured to provide for repositioning at least a portion of the housing with respect to the artificial airway. In an aspect of this embodiment, the at least a portion of the housing can be repositioned with respect to the artificial airway without opening the artificial airway to the atmosphere.Type: GrantFiled: April 28, 2009Date of Patent: August 26, 2014Assignee: Mergenat Medical, Inc.Inventors: Robert M. Landis, Charles A. Lewis, Angelo Caruso, Bruce Sher, Louis Javier Collazo, Sanjay Chandran

Patent number: 8397724Abstract: In accordance with at least one exemplary embodiment, a ventilation system for providing gas under a first pressure to the nose of a user and second pressure to the mouth of a user is disclosed. A ventilation system can include a flow generator that can be connected to a gas supply tube. The gas supply tube can be in fluid communication with a ventilation interface. At least a portion of the gas supply tube can have a divider within the channel of the tube forming a nasal passageway and an oral passageway. A nasal breathing chamber and an oral breathing chamber can be defined in the ventilation interface. The nasal breathing chamber can be in fluid communication with the nasal passageway. The oral breathing chamber can be in fluid communication with the oral passageway.Type: GrantFiled: December 22, 2008Date of Patent: March 19, 2013Assignee: Mergent SolutionsInventors: Bruce Sher, Shara Hernandez, Louis Javier Collazo, Sanjay Chandran
