Description

Visual oral trachea cannula auxiliary device Technical Field The invention relates to the field of medical instruments, in particular to a visual oral tracheal intubation auxiliary device. Background The oral tracheal intubation is an important means for establishing an airway in anesthesia, first aid and severe treatment, and guiding insertion is usually completed by matching an endotracheal tube with a guide wire in clinic. To improve the ability to view the airway structure during intubation, solutions have been developed in the prior art that integrate the illumination and camera assembly into the front end of the guide wire or into an associated guide device, and present the airway image via a display device to assist the operator in completing the positioning and advancement of the intubation. Through searching, the invention with the publication number of CN216629363U discloses an auxiliary guide wire for visual trachea cannula, which is provided with a camera at the front end of the guide wire/connecting wire and is matched with a display unit, so that an operator can observe the internal structure of an airway to assist cannula, improve the success rate of cannula and reduce the situation of mistakenly entering esophagus. In addition, through searching, publication number US20110160537A1 discloses a guide wire with a camera device, which is used for being matched with an endotracheal tube, and an image is acquired through an image acquisition unit and displayed by a display unit so as to improve the visualization degree in the intubation process. Furthermore, publication number WO2011068741 discloses a device for sensing the position of an endotracheal tube, which provides a sensing assembly on the tube and outputs a signal related to the distance of surrounding structures to distinguish between the sensor being located in different positions of the mouth, trachea or bronchi. However, the above-mentioned visual guide wire scheme mainly relies on single video imaging for judgment, and is often affected by epiglottis shielding, secretion attachment, instantaneous visual field loss and the like in the critical stage of intubation, so that whether the visual guide wire scheme passes through the glottis and enters the tracheal lumen is difficult to confirm stably in real time, and the visual guide wire scheme only depends on an external or single sensing mode positioning scheme, and may lack the instant guiding capability combined with the posture of the front end of the intubation and the spatial relationship near the glottis. Disclosure of Invention (One) solving the technical problems Aiming at the defects of the prior art, the invention provides a visual oral trachea cannula auxiliary device, which solves the problems that the prior visual cannula guide wire is easily blocked in a glottic area and is influenced by secretion, so that the visual field is unstable, and whether the front end of the guide wire passes through the glottic and enters a trachea cavity is difficult to be confirmed reliably in real time.
