Patent number: 8517016Abstract: A method and a microprocessor controlled device for use in medical evaluation of the pulmonary system. The method and device incorporate two different non invasive evaluative techniques. Passive auscultation provides indicators of lung condition. Active auscultation, a different evaluative technique, provides information or indications generally not available or provided from passive auscultation. Combining the information from both techniques greatly improves the ability to provide effective medical treatment.Type: GrantFiled: December 23, 2008Date of Patent: August 27, 2013Assignee: Pulmosonix Pty Ltd.Inventors: Richard G. Caro, Noam Gavriely

Patent number: 7850618Abstract: The present invention relates to a method of determining characteristics of biological tissues in humans and animals. In particular, it relates to determining the characteristics of tissues such as the lungs and airways by introducing a sound to the tissue, and recording the sound. The invention further includes an apparatus capable of such measurement. In a first aspect of the present invention there is provided a method of determining characteristics of biological tissue in situ, including: introducing a sound to the tissue at first position; detecting the sound at another position spaced from the first position after it has traveled through the tissue; calculating the velocity and attenuation of sound that has traveled through the tissue from the first position to another position; and correlating the velocity and attenuation of the detected sound to characteristics of the biological tissue.Type: GrantFiled: January 10, 2008Date of Patent: December 14, 2010Assignee: Pulmosonix Pty Ltd.Inventors: Malcolm Howard Wilkinson, Clive Andrew Ramsden, Philip John Berger

Patent number: 7708697Abstract: Airway monitoring apparatus 30 includes a driver 6 for applying sound in the audible frequency range to the airway of a subject and a detector 7 for monitoring the response of the airway, e.g. by detecting transmitted sound signal components and/or reflected sound signal components. Variations in the detected sound signal, e.g. energy, due to attenuation of the signal, give an indication of the state of the airway, e.g. airway patency, and can be used to monitor sleep-disordered breathing events, such as apnea and hypopnea, and to provide a breathing event index, e.g. AHI. The apparatus may provide servo-control for a respiratory assist device, such as a positive airway pressure device, so as to provide an appropriate pressure level setting. It may allow for home use of such devices and for home titration. It may also assist in discriminating central and obstructive breathing events, and in providing a measure of airway resistance.Type: GrantFiled: April 15, 2005Date of Patent: May 4, 2010Assignee: Pulmosonix Pty LtdInventors: Malcolm Howard Wilkinson, Clive Andrew Ramsden, Philip John Berger, Peter Camilleri, Jacqueline Anne Wilson, Frank Samuhel

Patent number: 7201721Abstract: A method of measuring tissue mobility includes applying an oscillatory force to a region of tissue and measuring the velocity with which the tissue moves in response to the applied force. Tissue mobility is then determined by a ratio of the tissue velocity to the applied force.Type: GrantFiled: December 2, 2004Date of Patent: April 10, 2007Assignee: Pulmosonix Pty LtdInventor: Malcolm Howard Wilkinson
