Problems solved by technology

[0005] In addition, preformed laryngeal masks are easy to place but not malleable, making them inconvenient for nasal, sinus, or head and neck surgery
At the same time, for patients with abnormal airway or small jaw, this laryngeal mask often cannot form a good laryngeal sealing condition
In contrast, flexible laryngeal masks are not easy to place and do not have a gastric discharge mechanism

Embodiment 1

[0032] refer to figure 1 , figure 2 with image 3 , the multi-lumen laryngeal mask of this embodiment, in addition to including the inflatable mask 1 and the ventilation tube A that the common laryngeal mask has, is also provided with a pharynx tube S, and the distal section of the pharynx tube S is arranged on the inflatable The back of the cover 1 has a pharyngeal opening 12.

[0033] The pharynx passage S is divided into two pharynx passages S1 and S2 at the back of the inflatable mask 1, which are respectively located in the shallow groove between the back 14 and the edge 15 of the mask on both sides of the back of the inflatable mask 1 , and continue to extend until the far end of the inflatable mask 1, creating a sufficient suction area at the lowest point of the throat around the laryngeal mask. The shape of the inflatable mask 1 is carefully designed, fully conforms to the structural characteristics of the conventional human throat, and cannot be easily changed. T...

Embodiment 2

[0044] refer to Figure 4 , on the basis of Embodiment 1, not only the gastric tube G is provided, but the video tube V is also provided in this embodiment. , the distal end of the ventilation tube A gradually turns to the midline of the laryngeal mask and is embedded in the back 14 of the inflatable mask 1 to form a transparent blind end for accommodating and protecting video components. The transparent blind end is located at the Describe the middle back of the cover back 14.

[0045] The inner diameter of the video tube V is 3.5mm. Equipped with a digital imaging probe with a diameter of 2.8-3.2mm or a flexible bronchoscope, it can provide video images of the larynx and glottis. The success rate is also helpful for diagnosing faults or abnormalities during the use of the laryngeal mask at any time. At the same time, the laryngeal mask can also be used as an auxiliary tool for tracheal intubation in difficult airways. After the laryngeal mask is installed, the video compon...

Embodiment 3

[0049] refer to Figure 5 , Image 6 with Figure 7 , in this embodiment, a pharyngeal tube S, a video tube V and a stomach tube G are provided; the video tube V is located on the left side of the ventilation tube A, and the stomach tube G is located On the right, the proximal segment of the pharyngeal tube S is completely freed from the airway A, forming a free end.

[0050] The free pharyngeal tube S is conducive to the symmetrical design of the laryngeal mask. The left side of the ventilation tube A is a video tube V, and the right side is a gastric tube G, which is symmetrical and beautiful and easy to operate.

Abstract

A laryngeal mask with multiple pipe cavities comprises a breather pipe and an inflation cover as well as an oropharynx through pipe, wherein the breather pipe is provided for an ordinary laryngeal mask, the inflation cover is connected with the breather pipe, and the oropharynx through pipe is adjacent to and independent from the breather pipe and leads to the back of the inflation cover; oropharynx secretion, blood or gastric reflux liquid gathered on the periphery of the inflation cover and the pharynx and larynx can be absorbed into the oropharynx through pipe through a plurality of oropharynx through holes in the far end of the oropharynx through pipe to be absorbed away and discharged, and inhalation by mistake or laryngismus is avoided.

Description

technical field [0001] The invention relates to the technical field of laryngeal masks, in particular to a multi-lumen laryngeal mask. Background technique [0002] Since the advent of the laryngeal mask in the 1980s, it has been widely used in various clinical situations, including airway management during surgical anesthesia, and is known as the three major respiratory tools together with the mask and tracheal intubation. When properly placed, the inflatable mask of the laryngeal mask covers and seals the larynx, with its tip falling just above the upper opening of the esophagus and the lumen of its ventilation tube facing the glottis. [0003] The laryngeal mask has many advantages. It can be used as a ventilation device, as a guide tube for tracheal intubation, and as a rescue tool for tracheal extubation in patients with difficult airways. However, during surgery, oral secretions, gastric reflux fluid, or airway bleeding may collect and remain in the oropharynx and pha...
