Abstract
Devices and methods for allowing for improved assisted ventilation of a patient. The methods and devices provide a number of benefits over conventional approaches for assisted ventilation. For example, the methods and devices described herein permit blind insertion of a device that can allow ventilation regardless of whether the device is positioned within a trachea or an esophagus.
Claims19
A method for ventilating an individual, the method comprising:
- inserting a working end of a ventilation device within a body passageway of the individual, wherein the ventilation device comprises a tubing, wherein the working end includes a distal opening and a medial opening proximally spaced from the distal opening, wherein the distal opening is fluidly coupled to a first lumen, wherein the medial opening is fluidly coupled to a second lumen, wherein the first lumen and the second lumen are housed within the tubing, wherein the first lumen and the second lumen are fluidly isolated from each other;
- drawing suction through the distal opening and maintaining the suction for a period of time;
- determining whether the body passageway is drawn against the distal opening by the suction;
- ventilating the individual through the medial opening upon determining movement of a wall of the body passageway, wherein ventilating the individual through the medial opening comprises maintaining suction through the distal opening;
- and
- ventilating the individual through the distal opening upon failure to detect movement of the wall of the body passageway.
3 more elements
A device for ventilating an individual through one or more body passageways, the device comprising:
- a tubular member having at least a first lumen and a second lumen, wherein the first lumen is fluidly coupled to a first opening located towards a distal portion of the tubular member, wherein the second lumen is fluidly coupled to a medial opening being located proximally to the first opening along a wall of the tubular member, wherein the first opening and medial opening are fluidly isolated within the tubular member, wherein the first lumen and the second lumen are housed within the tubular member, wherein the first lumen and the second lumen are fluidly isolated from each other;
- a control system having a suction source and a gas supply lumen, the control system having a valve configured to fluidly couple the ventilation source to the first lumen or the second lumen, wherein the control system is configured to draw suction through the first opening and the first lumen, wherein the control system is configured to monitor a fluid parameter of the ventilation source to determine collapse of the body passageway and formation of a seal at the first opening;
- wherein the control system is further configured selectively form a ventilation path from the supply lumen to the first lumen or second lumen by
- selecting the first lumen as the ventilation path if collapse of the body passageway is not detected;
- and
- selecting the second lumen as the ventilation path if collapse of the body passageway is detected;
- and
- wherein the control system is configured to ventilate the individual through the ventilation path and maintain suction while ventilating through the second lumen to prevent fluid from passing through the collapsed body passageway.
