Publication number: 20080051674Abstract: A nasal cannula, for supplying a respiratory gas to a patient, comprising: a pair of spaced apart supply lines which each have a head at one end thereof with a discharge opening therein. The opposite end of each supply line is connectable to a 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: ApplicationFiled: July 27, 2004Publication date: February 28, 2008Inventors: James M. Davenport, James N. Curti, Barry Crandall, Peter W. Salter

Patent number: 6786475Abstract: A bubble humidifier for adding humidity to supplied oxygen. The bubble humidifier has a humidifier base, for containing a quantity of liquid, and a cover for the humidifier base. The bubble humidifier has an oxygen inlet for supplying oxygen to the bubble humidifier and an moisturized oxygen outlet for connection to a moisturized oxygen supply conduit for supplying humidified oxygen to a patient, and the oxygen inlet being connected to a diffuser for diffusing the supplying oxygen within the bubble humidifier. The bubble humidifier has a pressure relief device for relieving excess pressure generated within the bubble humidifier during operation thereof. The bubble humidifier defining a longitudinal axis and the diffuser is arranged to discharge the oxygen from the diffuser substantially at an angle normal to the longitudinal axis of the bubble humidifier to minimize flow of liquid, contained within the humidifier base, from entering the moisturized oxygen outlet during operation of the bubble humidifier.Type: GrantFiled: May 17, 2002Date of Patent: September 7, 2004Assignee: Salter LabsInventors: Peter W.

Patent number: 5797627Abstract: A tubing end-piece interconnects a free end of a piece of tubing and a tubing connector or fitting so that a fluid can flow between the tubing and the fitting or connector. The tubing end-piece includes a body member extending along a longitudinal axis with a bore extending longitudinally therethrough. The body member has an elongated body portion, a doughnut-shaped head portion and a frustoconically-shaped tail portion. The body portion has an outer body surface configured in a shape of a frustum that tapers from a first end and towards a second end. The doughnut-shaped head portion is connected to the first end of said body portion and extends radially outwardly relative to the longitudinal axis to form in cross-section an outer curved surface commencing from the first end and terminating in an outer peripheral edge which defines a first opening into the bore.Type: GrantFiled: April 30, 1997Date of Patent: August 25, 1998Assignee: Salter LabsInventors: Peter W.
