Novel double-positioning visual device for tracheal cannula

Abstract

Provided is a novel double-positioning visual device for a tracheal cannula. The device includes a device host mechanism and a displayer, wherein the front half part of the device host mechanism is a J-shaped catheter guide rod which conforms to the arc structure of the human mouth cavity, and the back half part of the device host mechanism is a handle; double-positioning means that the left and right sides of the front end of the J-shaped catheter guide rod are provided with two sets of high definition camera lenses and lighting sources which are arranged in a front-back mode; the upper and lower sides of the front end of the J-shaped catheter guide rod are each provided with a sputum suction port for cleaning the mouth cavity; a supply pipeline port is arranged between the high definition camera lenses and the lighting sources at the front end of the J-shaped catheter guide rod, and used for supplying water or oxygen or medicine; the section of the J-shaped catheter guide rod is in a U shape, and the tracheal cannula is inserted in the airway along the groove bottom of a U-shaped groove. The front end of the novel double-positioning visual device is directly delivered to the position between the airway and the esophagus, so that the glottis is positioned above the front end of the novel double-positioning visual device, which solves the problem that under the condition of a difficult airway, tracheal cannula is difficult to be inserted.

Description

technical field [0001] The invention relates to a dual-positioning novel endotracheal intubation visualization device. Background technique [0002] Existing video laryngoscopes for endotracheal intubation (eg, figure 1 shown), the design of the laryngoscope is: a curved lens with a certain radian, its inner arc is a curved plane with a certain width, and the front half is a tongue depressor with a length of 30 to 50 mm, which is used to provoke the patient's The epiglottis exposes the glottis; part of the outer arc of the curved lens is the lumen for installing the camera lens, and part of it is the travel space for the tracheal intubation. Due to the large curvature of the lens spatula, the difficulty of tracheal intubation also increases accordingly. Contents of the invention [0003] The purpose of the present invention is to provide a new dual-positioning visual device for endotracheal intubation. Its design concept is essentially different from that of traditional ...

[0003] The purpose of the present invention is to provide a new dual-positioning visual device for endotracheal intubation. Its design concept is essentially different from that of traditional laryngoscopes. The front end of the present invention is directly delivered to the position between the "airway and esophagus", so that the glottis is located above the front end of the present invention, which overcomes the "impossibility of intubation" between the top of the spatula of the existing video laryngoscope and the video lens. control area", especially to solve the difficult problem of tracheal intubation in the case of difficult airway
