    Abstract: An endotracheal or tracheostomy tube with a cuff assembly includes a cuff pressure regulator and a leak detection system. Pressure sensors monitor and measure a tracheal wall pressure and pressures in the cuff assembly. An abnormal reading from the pressure sensors may initiate a cuff-pressure adjusting process. The leak detection system detects an air leak in the seal between the cuff assembly and the tracheal wall. A scented film with a predetermined scent is positioned on an inferior portion of the cuff assembly, distally from the seal with the tracheal wall. An air leak is indicated when the predetermined scent is detected in air in the trachea proximal to the cuff assembly. An air-circulation device generates air flow into the trachea such that a new batch of air may be sampled and tested. The detection of an air leak may initiate a cuff-pressure adjusting process.

  • Patent number: 11712537
    Abstract: The present disclosure pertains to a system and method for facilitating pressure support therapy, mechanical inexsufflation therapy, and suctioning therapy for a subject. The system and method described herein offer a novel combination of mechanical inexsufflation with suctioning from a vacuum system. The invasive nature of current closed suctioning systems poses many potential risks, such as tissue trauma, less optimum secretion clearance at the peripheral airway, and lung decruitment. The system and method described herein provide a non-invasive method of suctioning with a suctioning volume measurement and a monitoring alarm to ensure a baseline lung volume and a positive end expiratory pressure (PEEP) level are maintained. This non-invasive method of suctioning is provided together with mechanical inexsufflation and pressure support therapy.

  • Patent number: 11696993
    Abstract: 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.
