Patent number: 8631796Abstract: A laryngeal mask of the type used to facilitate lung ventilation and the insertion of endo-tracheal tubes or related medical instruments through a patient's laryngeal opening as used during general anesthesia, intensive care, or critical patient care is described that includes an inflatable positioning and a respiratory tube. The inflatable positioning shield is formed to fit within a patient's oropharynx, and has an inflatable, hollow peripheral portion, a pliable base in fluid communication with the peripheral portion, a shield recess formed after inflation of the peripheral portion, and a rear portion formed between the posterior base and the peripheral portion after inflation of the peripheral portion, wherein the posterior base has a recessed front portion.Type: GrantFiled: September 3, 2003Date of Patent: January 21, 2014Assignee: Cookgas, L.L.C.Inventor: Daniel J.

Patent number: 8631795Abstract: An enhanced airway for creating an airway in a patient including a rigid connector with an insertion portion inserted into a flexible tube, and a padding member surrounding the flexible tube and the inserted portion of the rigid connector. The rigid connector includes a circuit end that may be directly coupled to an anesthesia circuit, reducing risk of fire caused by diffusing oxygen. The circuit end may also be covered by an oxygen mask or left open and uncoupled. The flexible tube enables a comfortable and less-injury prone creation of an airway in the patient's oral cavity. The rigid connector prevents a patient from biting down and collapsing the flexible tube and, if also inserted in the patient's airway, an endotracheal tube or a laryngeal mask airway. The padding member cushions the rigid connector, preventing damage and injury to a patient's teeth upon biting the rigid connector.Type: GrantFiled: May 6, 2011Date of Patent: January 21, 2014Inventor: Roxanne R. McMurray

Patent number: 8631799Abstract: A nasal cannula for supplying a respiratory gas to a patient and a method of treating a patient with sleep disorder. The nasal cannula comprises a pair of spaced apart supply lines which each have a head at one end thereof with a discharge opening located therein. The opposite end of each supply line is connectable to a high flow respiratory gas source. Each head is sized to be snugly received and retained within one of the nasal cavities of the patient while forming a sufficient leakage passage, between a portion of inwardly facing nasal cavity skin of a patient and a portion of an exterior surface of the head, to facilitate exhausting of any excess respiratory gas supplied to the patient through the leakage passage and also facilitate inhalation of any room air required in excess of the respiratory gas to be supplied to the patient.Type: GrantFiled: January 23, 2009Date of Patent: January 21, 2014Assignee: Salter LabsInventors: James M. Davenport, James N. Curti, Peter W. Salter, James Chua, Barry Crandall

Patent number: 8631797Abstract: Spontaneous respiration is detected by sensors. An additional amount of oxygen is administered to the lungs via a jet gas current at the end of an inhalation procedure. Breathing volume, absorption of oxygen during inhalation, and clearance of carbon dioxide during exhalation are improved. If required, the exhalation procedure of the patient can be arrested or slowed by a countercurrent to avoid a collapse of the respiration paths. An apparatus including an oxygen pump can be connected to an oxygen source and includes a tracheal prosthesis that can be connected via a catheter. The respiration detections sensors are connected to a control unit for activating the oxygen pump. The tracheal prosthesis includes a tubular support body with a connection for the catheter, and the sensors are associated with the support body. The tracheal prosthesis and jet catheter are dimensioned so the patient can freely breathe and speak without restriction.Type: GrantFiled: April 14, 2009Date of Patent: January 21, 2014Assignee: Breathe Technologies, Inc.Inventors: Lutz Freitag, Gregory Kapust, Anthony D.

Patent number: 8622060Abstract: A supraglottic airway of the type used to facilitate lung ventilation and the insertion of endo-tracheal tubes or related medical instruments through a patient's laryngeal opening where the shield is designed to have an internal increase in pressure during assisted inhalation such as positive-pressure ventilation.Type: GrantFiled: March 28, 2011Date of Patent: January 7, 2014Assignee: Cookgas, LLCInventor: Daniel J Cook

Publication number: 20140000621Abstract: The cheek path airway fits a path between a user's lips and through the user's cheek pouch and rear-jaw gap, avoiding the user's bite. It provides supplemental air to a user's rear-mouth cavity independently of a user's nasal airways while a user's lips remain closed. The airway can be used in combination with mandibular jaw-control and tongue-control devices whereby the combination mitigates breathing restrictions in a user's nasal and throat airways. The cheek path airway can be combined with and stabilized by a cheek pocket anchor, formed of a resilient filament, that fits within a user's cheek pouch.Type: ApplicationFiled: April 18, 2013Publication date: January 2, 2014Inventor: Lowell R.

Patent number: 8616203Abstract: A patient interface for communicating fluids to and/or from a patient's nasal cavity and/or oral cavity is disclosed. In addition, a patient interface for fluid and physiological function monitoring proximate to the patient's nasal cavity and/or oral cavity is disclosed. An apnea monitor and a method for monitoring apnea are also disclosed.Type: GrantFiled: April 20, 2012Date of Patent: December 31, 2013Assignee: Ric Investments, LLCInventors: Michael B.
