Description

Anti-backflow laryngeal mask

Technical Field

The utility model relates to a laryngeal mask field, concretely relates to anti-refluence laryngeal mask.

Background

The laryngeal mask is a breathing device widely used in clinical anesthesia, is more applied in small-sized operations with low requirements on muscle relaxation, is simpler to use, can be inserted into the throat of a patient without the assistance of muscle relaxing medicines and a laryngoscope, has less stimulation to the patient, and can keep spontaneous breathing of the patient in the operation process.

However, the laryngeal mask of the prior art has the following disadvantages: (1) the patient often needs to bite the outside of the insertion tube in the use process, which is not safe, and can cause uncomfortable feeling to the patient, thereby influencing the treatment.

SUMMERY OF THE UTILITY MODEL

This neotype aim at: an anti-reflux laryngeal mask is provided.

In order to achieve the purpose, the novel technical scheme is as follows:

a backflow prevention laryngeal mask comprises an insertion tube, a mask sac and a mask sac inflation tube, wherein a ventilation tube and a stomach tube passage are arranged in the insertion tube, the end part of the mask sac is connected with a section of hollow esophageal tube, a first inflation cuff is arranged on the esophageal tube, and the first inflation cuff is connected with a first inflation valve through a first inflation tube;

the anti-backflow laryngeal mask further comprises a bite block, a first through hole is formed in the bite block, the inserting tube penetrates through the first through hole, an annular air bag is arranged between the first through hole and the inserting tube and connected with a second inflation valve through a second inflation pipeline, and the bite block and the inserting tube are fixed together after the annular air bag is inflated.

Preferably, said first inflatable cuff is elliptical in shape.

Preferably, a second through hole is formed in the bite block, and a saliva collecting pipe is arranged in the second through hole.

Preferably, the saliva collecting pipe comprises a pipe body, a cover body and absorbent cotton arranged in the pipe body, and meshes are uniformly arranged at the bottom of the end, inserted into the oral cavity, of the pipe body.

Preferably, the pipe wall of the lower section of the pipe body is uniformly provided with meshes.

Preferably, a groove is formed in the pipe wall of the pipe body along the length direction of the pipe body, a positioning hole is formed in the bite block and is perpendicular to the second through hole, and a positioning screw rod is arranged at the positioning hole and penetrates through the positioning hole and the groove to fix the bite block and the pipe body together.

Preferably, the annular air bag is arranged in the first through hole.

This neotype beneficial effect lies in:

by arranging the first inflatable cuff, after the inflatable cuff is filled with gas, the esophagus of a patient can be completely blocked, the connection between the stomach and the laryngeal part of the pharynx and the respiratory tract is interrupted, and the phenomena of backflow and aspiration of gastric contents are avoided.

Through set up the bite-block on the inserted tube, not only can guarantee safety, still improved patient's comfort level in the treatment process, through setting up annular gasbag, when confirming the position of bite-block at the inserted tube, aerify for annular gasbag for bite-block and inserted tube are together fixed.

Detailed Description

As shown in fig. 1-3: a throat mask for preventing backflow comprises an insertion tube 1, a mask bag 2 and a mask bag inflation tube 3, wherein an air tube 4 and a stomach tube passage 5 are arranged in the insertion tube 1, the end part of the mask bag 2 is connected with a section of hollow esophageal tube 6, a first inflation cuff 7 is arranged on the esophageal tube 6, and the first inflation cuff 7 is connected with a first inflation valve 9 through a first inflation tube 8; the anti-backflow laryngeal mask further comprises a bite block 10, a first through hole 101 is formed in the bite block 10, the inserting tube 1 penetrates through the first through hole 101, an annular air bag 11 is arranged between the first through hole 101 and the inserting tube 1, the annular air bag 11 is connected with a second inflation valve 13 through a second inflation pipeline 12, and the bite block 10 and the inserting tube 1 are fixed together after the annular air bag 11 is inflated.

In this embodiment, the first inflatable cuff 7 is preferably oval-shaped.

In the present embodiment, the annular balloon 11 may be disposed in the first through hole 101 or on the insertion tube 1, preferably in the first through hole 101.

Through setting up first inflatable cuff 7 in this novel, this inflatable cuff is full of after gaseous, can block up patient's esophagus completely, interrupts being connected between stomach and larynx of pharynx, the respiratory track, avoids taking place the phenomenon that stomach content backflows, mistake are inhaled. Through set up bite-block 10 on the intubate 1, not only can guarantee safety, still improved patient's comfort level in the treatment process, through setting up annular gasbag 11, when confirming bite-block 10 in the position of intubate 1, aerify annular gasbag 11 for bite-block 10 and intubate 1 are fixed together.
