Embodiment Construction

[0019] Such as figure 1 , figure 2 As shown, a laryngoscope piece of the present invention includes a laryngoscope piece main body 1 and a spatula 3. The spatula 3 is located on the upper part of the laryngoscope piece main body 1 and extends to the front end, and is integrated with the laryngoscope piece main body, wherein the laryngoscope piece One side of the main body 1 is provided with an endotracheal tube guide groove 2 with an incompletely closed cavity 21 , which is connected to the main body 1 of the laryngoscope blade by groove joint, bonding, pin joint or link. The endotracheal tube guide groove 2 is upturned, and its cross section is approximately "U" shaped. In particular, the endotracheal tube guide channel 2 of the laryngoscope blade is made of elastic material. In actual use, the endotracheal tube can enter along the lumen 21 of the endotracheal intubation guide groove 2, so that the outlet of the patient end of the guide groove lumen 21 faces the glottis. ...

Abstract

The invention discloses a novel laryngoscopic lens, which comprises a laryngoscopic lens main body and a tongue depressor, wherein the tongue depressor is positioned at the upper part of the laryngoscopic lens main body and extends to the front end of the laryngoscopic lens main body to form a whole with the laryngoscopic lens main body; an elastic trachea cannula guide slot with an incompletely closed cavity is formed on one side of the laryngoscopic lens main body, and is of a turned up shape; and the cross section of the elastic trachea cannula guide slot is approximately U-shaped. Structurally, the elastic trachea cannula guide slot is provided to carry out the elastic match between different models of trachea cannulas for being convenient for operators to implement the trachea cannula; and in addition, after the trachea cannula is successful, the trachea cannula is easy to separate from the laryngoscopic lens from the opening at the upper part of the guide slot because of the elasticity of the guide slot. The trachea is more accurate to enter the glottis since a patient end of the trachea cannula guide slot is of the turned up shape. Furthermore, the trachea cannula guide slot adopts a sectional type, so that the frictional resistance surface of the trachea cannula and the guide slot is reduced, and at the same time, the difficulty in cleaning and disinfecting is reduced.

Description

technical field [0001] The invention relates to a medical device component, in particular to a laryngoscope blade mainly used in a laryngoscope for exposing a patient's larynx and glottis and performing endotracheal intubation. Background technique [0002] Endotracheal intubation is an important critical step in first aid and general anesthesia. Its success directly affects the rescue success rate and the success or failure of general anesthesia. The human upper respiratory tract is a curved and irregular duct formed by the combination of bone, cartilage and muscle tissue. The traditional direct laryngoscopy method is to insert the laryngoscope from the mouth, along the tongue to the junction of the tongue base and the epiglottis, then lift the laryngoscope to expose the glottis, and insert the endotracheal tube through the glottis into the trachea under direct vision. The angle of the glottis should be such that the line of sight overlaps with the upper incisor and the g...
