The present invention relates to a tracheal protective ventilation device specially adapted for use with neonates, a stylet that aids in insertion and spatial verification of the tracheal protective ventilation device, and methods for using the same. The ventilation provided by the devices of the present invention is atraumatic to the trachea and the glottis compared to ventilation devices currently available in the art, and has the additional feature of allowing the administration of nutritional matter to the gut without interrupting airflow.

An endotracheal tube is disclosed that allows a patient to speak while intubated. The endotracheal tube includes a balloon for seating against the trachea and a collapsible portion proximal to the balloon that aligns with the vocal cords. The collapsible portion may be held open by an inner tube which translates within the endotracheal tube. Suction and balloon inflation conduits span the collapsible portion so that suction and balloon inflation may be performed while the patient is speaking. A small distal tube that bypasses the balloon provides some airflow while the patient speaks.

A non-ventilator ET tube cap used to oxygenate a patient during an intubation procedure. The ET tube cap generally comprises an oxygen source connector configured to connect to an oxygen source via an oxygen tube. This provides oxygen to a patient via an ET tube while being intubated. The ET tube cap further includes an ET tube receiving aperture that is specifically arranged to engage an ET tube in a removable relationship prior to the ET tube connected to a ventilator while the ET tube is deployed in a patient. Optionally, the ET tube cap can comprise at least two pressure relief valves that open when pressure inside of the ET tube cap exceeds a predetermined pressure threshold to prevent harm to the patient that is being intubated.

A laryngeal mask airway device (20, 320) is provided including an inflatable balloon (30, 330), which is (a) shaped so as to define at least an inflatable annular cuff (32, 332) and a proximal inflatable pharyngeal portion (34, 334), and (b) insertable through an anterior opening of a patients oral cavity. The inflatable balloon (30, 330) is configured such that when an inflatable chamber (56) thereof is filled with air at a pressure of 10 cm H2O and unconstrained, a volume of the air in a proximal one-third (60) of the inflatable chamber (56) equals at least 200% of a volume of the air in a distal one-third (62) of the inflatable chamber (56). Other embodiments are also described.

A device for targeted delivery of a substance to an airway may include a conduit and at least two applicators. The conduit may include a proximal end and a bifurcated distal portion having two distal ends. Each applicator may be coupled with one of the distill ends of the conduit and may be configured to direct the substance out of the applicator toward one of two sides of an airway. A method for targeted delivery of a substance to an airway may involve advancing a substance delivery device into the airway, contacting two sides of the airway with at least two applicators of the substance delivery device, such that each applicator contacts the airway near a glossopharyngeal nerve and/or a superior laryngeal nerve on each of the two sides of the airway, and delivering the substance through the applicators to contact the airway along the two sides.

The invention relates to a device for the dynamically adapting sealing of an organ or a body cavity, e.g. the windpipe (trachea) of an intubated and ventilated patient, wherein the sealing balloon element is produced via particularly rapid shifting of filling medium from an extracorporeal reservoir or an extracorporeal source to the sealing balloon, and wherein, in the dynamic sealing of the trachea according to the example case, a balloon-type foil body preferably formed with residual material in the diameter, i.e. exceeding the tracheal diameter, is in contact with the inner wall of the trachea in a sealing manner and with a pressure that is as constant as possible, wherein fluctuations in the balloon volume, caused by fluctuations in the intrathoracic pressure relating to the mechanics of breathing, are compensated as quickly as possible by supplying volume from an extracorporeal reservoir or an extracorporeal source, and the tracheal secretion sealing of the balloon is thereby kept continuous. This is both made possible by a sufficiently high-volume supply of the balloon filling medium to the cuff, and also prevents steps, gaps or ridges in the supply system, whereby volume flow directed towards the balloon can be minimised, which is crucial for a rapid-as-possible stabilising of the filling volume in the balloon, in particular with small pressure differences between 15 and 30 mbar that are driving the volume flow.

An airway device includes an outertube and a scope channel partially enclosed by the outertube. An intraluminal space in the outertube, not occupied by the scope channel, provides a passageway for air flow to the patient. An esophageal cuff is disposed distally on the scope channel. When inflated, the esophageal cuff secures the airway device in the proximal esophagus of the patient and helps to prevent gastric reflux by mechanically blocking gastric content from entering into the larynx. An inflatable bladder is attached at an anterior surface of the scope channel between the esophageal cuff and a distal opening of the outertube. When inflated, the bladder forms a tubular ring that pushes against the epiglottis and/or other soft tissue towards a wall of the hypopharynx to produce an unhindered air passage into the patient's trachea.

An airway management device comprising a body having a proximal end for receiving an oxygen supply tube and an distal end for insertion into a trachea of a patient; said body including a linear portion adjacent to the proximal end and a curved portion adjacent to the distal end; said body including an external shell and having a first bore through said shell for receiving the oxygen supply tube; wherein flexural strength for said airway management device is provided by said shell.

Systems and devices for monitoring, detecting, and removing fluid build-up found at various regions along a tracheal tube of an intubated patient. The fluid management system includes pressure and flow sensors for detecting whether there is fluid at the various regions along the tracheal tube, and a means for drawing out the fluid into collection jars. The system also includes lavage features that is able to rinse different the various regions along a tracheal tube. Also disclosed are respiration insertion devices that either couple to existing tracheal tubes or incorporate tracheal tubing, where the respiration insertion body has channels and ports that contact various regions along the tracheal tube. The combination of the fluid management system and the respiration insertion devices effectively monitor and remove fluid at various locations along a tracheal tube of an intubated patient.

A pulmonary secretion clearing airway structure and related airway management system is disclosed that has a double lumen portion which each lumen of the double lumen portion operably secured to an airway management system so that inspiratory fluid (air/oxygen mixtures, with or without added water vapor) is delivered to the distal end of the ventilation catheter through one of the two lumens and expired inspiratory fluid, pulmonary secretions, and pulmonary fluids are removed from the patient through the other lumen. The expiratory fluid pathway preferably includes a secretion collection system for removing the pulmonary secretions and the like from the pathway, thereby improving operation and safety of the system. The airway structure can be a ventilation catheter or a supraglottic airway system such as laryngeal mask and the like.
