Abstract
The present invention provides an improved visual laryngeal mask comprising a tube, an end of the tube is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. An imaging cavity extends longitudinally inside an inner wall of the tube. The imaging cavity has a built-in imaging device, and the imaging cavity protrudes forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device. A front end of the stopper is concaved to form a recess, and an opening of the imaging cavity is located at a low point of the recess.
Core Innovation
An improved visual laryngeal mask includes a tube in which an end of the tube is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess provided with an airway opening. The recess cooperates with the airway opening as part of the structure of the laryngeal mask.
An imaging cavity extends longitudinally inside an inner wall of the tube and is able to be used for a built-in imaging device. The imaging cavity protrudes forward relative to the airway opening to form a stopper adapted to prevent an epiglottis from blocking the imaging device, and a front end of the stopper is concaved to form a recess with the imaging cavity opening located at a low point of the recess.
In a described embodiment, the airbag includes an esophagus sealing capsule and an airway sealing capsule that communicate to form a separation region so that an expansion height of the esophagus sealing capsule is smaller than an expansion height of the airway sealing capsule along a boundary between an esophagus and an airway. The arrangement is intended to reduce leakage, reflux, and esophageal pressure while improving ventilation and reducing complications.
Claims Coverage
The document contains one independent claim defining the core structure of an improved visual laryngeal mask, with dependent claims refining the stopper, imaging device, and airbag sealing arrangement.
Tube with fixing seat airbag and airway opening recess
An improved visual laryngeal mask comprising a tube, an end of the tube provided with a fixing seat, wherein the fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening.
Longitudinal imaging cavity inside tube for built-in imaging device
An imaging cavity extends longitudinally inside an inner wall of the tube, wherein the imaging cavity is able to be used for a built-in imaging device.
Forward-protruding imaging cavity stopper prevents epiglottis blockage with concaved front recess
The imaging cavity protrudes forward relative to the airway opening to form a stopper which is adapted to prevent an epiglottis from blocking the imaging device; wherein a front end of the stopper is concaved to form a recess, and an opening of the imaging cavity is located at a low point of the recess of the stopper.
The claim coverage centers on a tube-based visual laryngeal mask with an airbag on a fixing seat and a recessed airway opening, combined with a forward-protruding longitudinal imaging cavity that forms a concaved stopper arrangement to prevent epiglottis blocking of a built-in imaging device.
Stated Advantages
Improve ventilation and reduce complications.
Reduce leakage, reflux, and esophageal pressure.
