| 20090306528 | ADAPTIVE TEMPERATURE SENSOR FOR BREATH MONITORING DEVICE - A system and method for sleep monitoring, diagnosing and sensing temperature and pressure for a breathing cycle of a patient including a sensing device suitable for both nasal and oral breath monitoring for measuring respiratory air wave and airflow information during a sleep apnea diagnostic session and processing the acquired air wave and airflow breathing information for input to conventional polysomnography equipment. | 12-10-2009 |
| 20090306529 | ADAPTIVE TEMPERATURE SENSOR FOR BREATH MONITORING DEVICE - A system and method for sleep monitoring, diagnosing and sensing temperature and pressure for a breathing cycle of a patient including a sensing device suitable for both nasal and oral breath monitoring for measuring respiratory air wave and airflow information during a sleep apnea diagnostic session and processing the acquired air wave and airflow breathing information for input to conventional polysomnography equipment. | 12-10-2009 |
| 20100113956 | NASAL CANNULA FOR ACQUIRING BREATHING INFORMATION - A nasal cannula for monitoring symptoms of sleep apnea and hypopnea, including an elongated main body having a main body chamber and first and second nares to be received within first and second nasal passages of a patient's nose and at least one mouthpiece extending to a patient's mouth. The main body chamber communicates with first and second cannula inlet/outlets and each nare and the mouthpiece includes a gas flow passage extending from the nostril or mouth to the main body chamber. At least one nasal gas flow sensor is located in an gas flow passage of at least one of the nares and at least one oral gas flow sensor located in the mouthpiece gas flow passage, preferably in the regions of the gas flow passages adjacent the main body chamber. | 05-06-2010 |
| 20100139664 | NASAL AND ORAL CANNULA HAVING TWO CAPABILITIES AND METHOD OF PRODUCING SAME - A method of forming a cannula from a cannula mandrel assembly comprising a pair of mouthpiece/nasal mandrels and a mating facepiece mandrel. The facepiece mandrel has a pair of conical holes, in an intermediate section thereof, for receiving a leading end of one mouthpiece/nasal mandrel. The conical holes allow the facepiece mandrel to slide along the mouthpiece/nasal mandrels until the conical holes abut with respective mating tapering conical sections and prevent further sliding movement along the mouthpiece/nasal mandrels. Following assembly, the assembly is heated, at least one coating of a polymeric material is applied thereto and heat from the assembly at least partially cures the polymeric material on the assembly. Following curing, the facepiece mandrel and formed cannula are slide along the mouthpiece/nasal mandrels until the facepiece mandrel and formed cannula are removed therefrom. Lastly, the facepiece mandrel is removed from the formed cannula. | 06-10-2010 |
| 20100168600 | SUPPORT STRUCTURE FOR AIRFLOW TEMPERATURE SENSOR AND THE METHOD OF USING THE SAME - A temperature sensing device and method of using the same, for detecting breathing of a patient. The temperature sensing device comprises a sensor body contour for supporting the temperature sensing device on an upper lip of a patient and preventing undesired movement thereof and at least one temperature sensor being supported by the sensor body. The sensor body spaces the temperature sensor(s) from the skin of a patient, during use, so that a remote end of the at least one temperature sensor can be positioned adjacent at least one of a nasal cavity and a mouth of the patient for detecting breathing of the patient. The sensor body is preferably curved both upwardly and rearwardly with respect to planes extending through the sensor body. | 07-01-2010 |
| 20100168601 | COMBINED CANNULA AND AIRFLOW TEMPERATURE SENSOR AND THE METHOD OF USING THE SAME - A combined cannula and temperature sensing device for detecting breathing of a patient. The cannula comprising a cannula body defining at least one internal flow chamber therein, at least one tube being connected to the cannula body and communicating with the internal flow chamber, a pair of nasal prongs communicating with the internal flow chamber, and the cannula body having retaining mechanism for releasably attaching the temperature sensing device to the cannula. The temperature sensing device comprising a sensor body, at least one temperature sensor being supported by the sensor body, and the sensor body releasably engaging with the retaining mechanism of the cannula for positioning the at least one temperature sensor adjacent at least one of a nasal cavity and a mouth of the patient for detecting breathing of the patient. | 07-01-2010 |
| 20110125052 | RESPIRATORY THERAPY SYSTEM INCLUDING A NASAL CANNULA ASSEMBLY - 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. The invention also relates to a respiratory therapy system incorporating the nasal cannula, a method of treating a patient with sleep disorder by using the nasal cannula, a diagnostic tool for measuring nasal cavity pressure of a patient, and a method of using the diagnostic tool for measuring nasal cavity pressure of a patient. | 05-26-2011 |
