Embodiment 1

[0031] Example 1 Reference Figure 1 to Figure 4

[0032] A disposable video laryngoscope piece with a tracheal intubation guide groove and an airway surface anesthesia guide groove, including an arc-shaped sleeve 1 made of transparent material for being sleeved on the curved tube of the video laryngoscope. The front end of the shaped sleeve is provided with an integrally formed sealing plate 2, and the sealing plate is perpendicular to the shooting direction of the camera arranged at the front end of the elbow, thereby ensuring the camera effect. The upper side of the arc-shaped sleeve is provided with an arc-shaped guide tongue 3 for holding the tongue and guiding, and one side of the arc-shaped sleeve is provided with a first guide groove 4 for the endotracheal tube to pass through. The lower side of the tube is provided with a second guide groove 5 for passing the laryngeal anesthesia tube, so as to realize both tracheal intubation and guidance of the laryngeal anesthesia...

Abstract

The invention relates to a disposable video laryngoscopic lens with tracheal cannula guide channel and airway surface anesthesia guide channel and an application method thereof, and applies to the field of medical instruments. The disposable video laryngoscopic lens comprises a bent tube for sleeving a video laryngoscopic lens and an arc cannula made of transparent material, the front end of the arc cannula is provided with an integrally formed seal plate, the upper portion of the arc cannula is provided with an arc guide tongue carrier sheet for carrying the tongue and for guidance, one side of the arc cannula is provided with a first guide channel for passage of a tracheal cannula, and the lower portion of the arc cannula is provided with a second guide channel for passage of a laryngotracheal anesthetic tube. The disposable video laryngoscopic lens can decrease pollution of the tracheal cannula by buccopharyngeal secretion during tracheal cannulation, and allows tracheal cannulation to be performed with no need for the assistance from a tube core; in addition, before oral tracheal cannulation, precise buccopharyngeal surface anesthesia of the laryngotracheal tube is facilitated, and operation is simpler and easier.

Description

technical field [0001] The invention relates to a disposable video laryngoscope with a tracheal intubation guide groove and an airway surface anesthesia guide groove and a use method thereof, which is suitable for the field of medical instruments. Background technique [0002] The video laryngoscope is favorable for exposure of the higher glottis due to the radian of the laryngoscope blade and the large angle of the front end. Disposable laryngoscope blades can avoid cross infection. Therefore, videolaryngoscopes equipped with disposable laryngoscope blades are widely used for tracheal intubation in general anesthesia in current clinical anesthesia practice. However, there are no disposable video laryngoscope blades with tracheal intubation guide grooves on the market of medical materials at present, and video laryngoscopes with disposable laryngoscope blades are all completed by molding the endotracheal tube into a fishhook shape through the tube core Intubation. When th...
