11744972 · 2023-09-05 ·

A cuff assembly for a tracheostomy tube includes an outer bladder and an inner cuff. The inner cuff is positioned adjacent to the tracheostomy tube, and the outer bladder is positioned adjacent to the inner cuff. The outer bladder is made with a less elastic material and operates at a higher relative pressure. The inner cuff is made with a more elastic or hyper-elastic material and operates at a lower relative pressure. A secondary airflow opening is formed on a lateral wall of the tracheostomy tube between the cuff assembly and a main distal opening of the tracheostomy tube.

System and method for pressure management and air leak detection of an inflatable cuff in a medical device
11819611 · 2023-11-21 ·

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.

SPEECH VALVE

A speech valve to be connected to a respiration opening of a tracheostomy tube includes: a passage portion communicating with the respiration opening; a balloon disposed within the passage portion, and configured to deform from a shrink state, in which the passage portion is opened, to a bloat state, in which at least a part of the passage portion is closed so as to inhibit discharging of exhaled air through the passage portion; an automatic pump switching between supplying and stopping in accordance with an operation of an operation unit, and continuously supplying air to the balloon when supplying; and a coupling tube connecting the automatic pump and the balloon.

A medical mechanical controlled balance ventilation single-lumen lung isolation catheter bridging spans trachea to bronchus and by-pass flow gas holes of wall, which has a intraluminal main trachea tube and a distal intraluminal bronchus tube in communication with one end of the intraluminal main trachea tube; a first opening is provided at a rear end of the distal intraluminal bronchus tube; a second holes opening zone having at least two holes is provided at a side wall of a lower end of the intraluminal main trachea tube; the transmural holes of the second holes opening zone are distributed along a same or different horizontal sectional surface or vertical sectional surface of a three dimensional space formed inside the intraluminal main trachea tube.

Medical apparatus with hypopharyngeal suctioning capability
11077271 · 2021-08-03 · ·

A laryngeal mask apparatus includes a mask portion, a breathing tube and a suction tube. The suction tube is adapted for connection to a suction-producing device. The suction tube further includes suction ports that suck fluids and secretions from the patient's hypopharyngeal region when suction is created within the interior of the suction tube. The breathing tube is adapted for connection to a ventilating system. Air flows through the breathing tube and into the mask portion. A capillary tube is positioned within the interior of the suction tube. When the mask portion is positioned within a patient's throat and suction is created within interior of the suction tube, the suction ports suck the fluids and secretions in the patient's hypopharyngeal region. At the same time, the suction tube and capillary tube cooperate to provide a stream of air that decreases the direct suction forces on the mucosa of the patient's throat that are caused by the suction ports. The laryngeal mask apparatus includes a scope tube having an interior and an inner tube disposed within the interior of the scope tube. The inner tube is sized for receiving a gastric tube.
