Publication number: 20240123172Abstract: A system of treating atelectasis is provided that includes a tracheal tube positioned within an airway of a ventilated patient and an acoustic sensor coupled to the tracheal tube. The system also includes a monitor communicatively coupled to the acoustic sensor. The monitor includes a processor configured to receive a baseline signal from the acoustic sensor. The processor is configured to provide control instructions to adjust a pressure of a gas mixture delivered to the airway through the tracheal tube. The processor is also configured to receive an updated signal from the acoustic sensor after the adjustment and identify a change in airway openness of lungs of the ventilated patient caused by the adjustment of the pressure. Further, identifying the change is based on the baseline signal and the updated signal.Type: ApplicationFiled: December 22, 2023Publication date: April 18, 2024Applicant: COVIDIEN LPInventors: Gardner Kimm, Phyllis R.

Publication number: 20230320675Abstract: Systems and methods for identification and display of airway collapse due to conditions such as tracheomalacia (TM) or dynamic airway collapse (DAC). In an aspect, the technology relates to a method for identifying airway collapse. The method includes emitting, from an acoustic sensor, a series of acoustic pulses into a tracheal tube positioned in an airway of a patient; detecting, by the acoustic sensor, echoes resulting from the series of acoustic pulses; generating, based on the detected echoes, a time series of passageway sizes of the airway; based on the time series of passageway sizes, detecting an airway collapse has occurred; and based on detecting the airway collapse has occurred, activating an airway collapse alarm.Type: ApplicationFiled: April 3, 2023Publication date: October 12, 2023Applicant: Covidien LPInventor: Jeffrey P.

Publication number: 20230285701Abstract: The present disclosure relates to a system and method for use of acoustic reflectometry information in ventilation devices. The system and method includes a speaker to emit sound waves into an intubated endotracheal tube (“ETT”) and a microphone to detect returning acoustic reflections. In addition, the system and method includes a reflectometry device in communication with a ventilation device for analyzing timings and amplitudes of the returning acoustic reflections to determine a size of a passageway around an ETT tip, location and size of ETT obstructions, and relative movement of the ETT tip within a trachea. The reflectometry device is also configured to determine a resistance parameter representative of resistance to actual flow of air through the ETT based upon a function of the diameter of the ETT, length of the ETT, and percent obstruction of the ETT, where the resistance parameter is used to calculate the tracheal pressure.Type: ApplicationFiled: May 23, 2023Publication date: September 14, 2023Applicant: Covidien LPInventors: Jeffrey P.

Patent number: 6705319Abstract: An apparatus and method are disclosed for acoustically guiding a distal end of a tube within a body. An incident sound pulse is generated and propagated down the tube into the body. A plurality of microphones are located in the tube and are positioned to detect pulses traveling through the tube. A discriminator distinguishes between incident sound pulses and those that are reflected from within the body. The detected sound pulses are processed to provide an indication of the location of the distal end of the tube within the body, to assist with the guidance of the insertion into the body, to estimate dimensions of the body adjacent the distal end of the tube, and to determine if the tube is obstructed.Type: GrantFiled: May 26, 2000Date of Patent: March 16, 2004Assignee: Purdue Research FoundationInventors: George R.
