Publication number: 20130146064Abstract: A harness for securing a nasal cannula to a user for the purpose of delivering oxygen. The harness comprises an upper and lower strap located at the top and rear of a user's head, respectively. The upper and lower straps are orthogonally connected at their midpoint by a vertical connecting strap, and contain on either end, an adapted means to secure and support a nasal cannula by looping around the plastic tubing and then attaching onto itself. Two distinct connection points above and below each ear maintain the suspended position of the cannula without deforming its cross section. By providing a three-strap methodology for supporting the nasal cannula and maintaining positive control of the plastic tubing by keeping it suspended above the ears, the present invention avoids commonly associated drawbacks related to existing devices.Type: ApplicationFiled: December 10, 2012Publication date: June 13, 2013Inventor: Helen Dryden

Patent number: 8453649Abstract: A harness for securely positioning a nasal cannula on the face of a person for orally administering oxygen and other gases is described. A flexible chin strap adapted for placement around the chin of the person may be attached to adjustable, flexible straps effective for draping around the ears of the person, which are in turn attached to a central, cannula attachment portion disposed between the cannula and the face of the person. The gas delivery tubes of the cannula are also disposed behind the ears, essentially following the path of the flexible straps of the harness. Once placed on a person, the harness holds the nasal cannula such that the nasal prongs may disposed facing toward the mouth opening in the vicinity of the lower lip thereof, and may deliver gases to a mouth-breathing individual. Another embodiment of the harness may be utilized to position a nasal cannula for nasal administration of gas.Type: GrantFiled: February 12, 2010Date of Patent: June 4, 2013Assignee: 0200L, LLCInventor: John P. O'Leary

Patent number: 8434493Abstract: The adjustable mouth shield device provides an adjustably fitted mouth shield with adjustable headband for secure fit. The adjustable headband is fastened to the padded earpiece. The straight first extension from the earpiece is angled downwardly and forwardly to terminate in a swivel joint providing almost 360 degrees of swivel. The second extension is arced both downwardly and forwardly. The u-shaped mouthpiece is fitted to the adjustable spring mount for horizontal pivot of the mouthpiece. The mouthpiece may, by virtue of the swivel joint and the spring mount, be moved completely away from a user's mouth and, in turn, pivoted and swiveled to be directly in front of the user's mouth. The inward curves at the distal end of the mouthpiece aid in sliding on the disposable pads that shield a user from objects, foods and other materials.Type: GrantFiled: February 4, 2011Date of Patent: May 7, 2013Inventors: Eric McGhie, Darrell Harvey

Patent number: 8430098Abstract: A strapless nasal interface device is disclosed. The device is used in conjunction with CPAP, BIPAP, ventilators, or any other suitable device. The device includes a body with a passageway to a ventilating tube, exhalation holes, and a passageway to nostril interface tubes. The nostril interface tubes include a nasal interface element which is an expandable, compressible material such that the user can compress the element, insert it into the end of the nostril and allow it to expand to hold the tube in place. Alternatively, the nasal interface elements are held against the outer edge of the nostrils. Optionally, a skirt is included at the outer side of the nostril to aid in sealing against air leaks. Optionally, flaps are included to assist in holding the device in place, such as side flaps, a front flap, or both. The front flap may be adherable to the exterior of the nose and optionally includes resilient strips to open the nasal passageway.Type: GrantFiled: December 17, 2009Date of Patent: April 30, 2013Inventor: Venkata Buddharaju
