Disposable laryngoscope piece with intubation guiding slot

Abstract

The invention provides a disposable laryngoscope blade with an intubation-guided slot, comprising a laryngoscope blade main body and a spatula, both of the laryngoscope blade main body and the spatula depressor are arc-shaped with concave surfaces facing upward, and the spatula depressor is set On the upper part of the laryngeal blade main body, the laryngeal blade also includes a base plate, and the base plate is provided with a baffle on the side opposite to the laryngeal blade main body, and the side of the laryngeal blade main body, the tongue depressor, the base plate and the baffle form an intubation tube Guide-type card slot, the width and height of the intubation-guided card slot gradually decrease from the entrance to the outlet of the intubation-guided card slot, and the baffle plate is provided at the outlet end of the intubation-guided card slot In the guiding device, the main body of the laryngoscope blade, the tongue depressor, the baffle and the bottom plate are integrally formed. The invention has simple structure and convenient operation, can perform intubation on patients quickly and accurately, greatly improves the accuracy and efficiency of intubation, and reduces the injury of patients to the greatest extent.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and particularly relates to a laryngoscope. Background technique [0002] In current clinical medicine, the patient’s breathing needs to be maintained during anesthesia or rescue. Therefore, tracheal intubation is the most basic treatment and first aid method. It is very important. Because the structure of the human throat is complex, it is often necessary to use the throat The technology has been developed greatly. The traditional laryngoscope method is to insert the laryngeal lens from the mouth along the tongue to the epiglottis, and then use the laryngeal lens to lift the epiglottis to expose the glottis. At this time, the medical staff then put the tracheal tube through the sound Door insertion. This intubation technique relies on naked eyes. The line of sight is limited by the edges of the teeth and the curved respiratory tract. It is prone to parallax and blind spots, resulting in unclear expos...

AI Technical Summary

Problems solved by technology

[0005] 1). Since the guide groove and the laryngoscope body are not integrally formed, they are grooved, glued, pinned or linked, so the structure is more complicated and the production cost is higher

[0006] 2). When performing intubation, the center of the glottis is the best position for intubation. It is very important to fully expose the epiglottis and glottis during intubation, which is directly related to the success of intubation. Therefore, the medical field generally uses cameras The center of the field of view is directly opposite to the glottis. Although the guide groove of the laryngoscope serves as a guide for the endotracheal tube, the direction of the guide groove is parallel to the camera tube (see the attached figure in the manual). Yes, the endotracheal tube will be entered from the side of the patient's tracheal lumen, which is not conducive to intubation
