Problems solved by technology

However, when high-pressure ventilation is required, such as laparoscopic surgery, the effective ventilation volume of ordinary laryngeal masks decreases due to air leakage, resulting in hypercapnia

Embodiment

[0024] Such as figure 1 Shown is a schematic structural view of a novel laryngeal mask with multiple tracheal channels provided by the present invention, including an air bag 1, a ventilation tube 2, a tracheal channel joint 3, an inflatable tube 4, an indicating air bag 5 and a one-way valve 6; the air bag 1 A wedge-shaped groove 7 is arranged in the center of the vent pipe 2; the air inlet end of the vent tube 2 is connected to the internal interface of the trachea channel joint 3;

[0025] Such as Figure 2-4 As shown, the ventilation tube 2 is divided into a trachea main channel 21, a trachea left channel 22 and a trachea right channel 23 communicating with each other at its air outlet end, and the trachea left channel 22 and the trachea right channel 23 are located in the trachea main channel respectively. 21 on both sides or below both sides; the wedge-shaped groove 7 is provided with an epiglottis lifting platform 8 at the air outlet of the main channel 21 of the trach...

Abstract

The invention provides a novel laryngeal mask with multiple trachea channels. The novel laryngeal mask comprises an air bag, an air tube, a trachea channel connector, an inflation tube, an indicating air bag and a check valve. The center of the air bag is provided with a wedge-shaped groove. The novel laryngeal mask does not have an esophagus drainage tube, so that the whole size is reduced, placement of the laryngeal mask is convenient and operations can be more convenient and rapid; the air tube is divided into a trachea main channel, a trachea left channel and a trachea right channel, which communicate with one another, at an air outlet end, so that even if one or two channels are shielded or blocked, an air flow effect can be guaranteed, normal air flow during operation can be guaranteed and medical accidents of suffocation of patients can be avoided.

Description

technical field [0001] The invention relates to the technical field of anesthesia medical instruments, in particular to a novel laryngeal mask with multiple tracheal channels. Background technique [0002] Double tube laryngeal mask, also known as esophageal drainage type laryngeal mask, is the third generation of laryngeal mask. Currently, there are three types of esophageal drainage LMA widely used clinically: Proseal LMA, Supreme LMA improved on the basis of Proseal LMA, and I-gel LMA without cuff. The main feature of the esophageal drainage LMA is the addition of a drainage tube that seals and drains the gastrointestinal tract. Therefore, the esophageal drainage type laryngeal mask has the function of preventing reflux and aspiration. At present, in addition to being widely used in short body surface and limb surgery of adults and children under general anesthesia, the esophageal drainage type laryngeal mask is further applied to laparoscopic surgery, open abdominal su...
