Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

Example 1

As further described below with reference to specific embodiments, referring to fig. 1-2, embodiment 1 is a comfortable and convenient laryngeal mask, which includes a mask sac 1 and a tube body 2, the mask sac 1 is communicated with an inflation tube 3, the inflation tube 3 is fixed on the inner wall of the tube body 2 to form an integrated structure, and extends out from the tail end of the tube body 2; the elastic metal wire 6 embedded in the tube wall is arranged in the tube body 2, and particularly, compared with a laryngeal mask in the prior art, the utility model has the advantages that the inflation tube 3 is arranged in the tube body 2, so that the cross section area of the tube body 2 is reduced to a certain degree, the ventilation efficiency is reduced, the discomfort degree and nausea of a patient caused by relative sliding displacement possibly existing after a plurality of tubes are inserted into the throat are avoided, and the irritation is stronger; in addition, the inner wall of the tube body 2 is provided with holes for penetrating the elastic metal wires 6, so that the tube body 2 has certain strength, and when the laryngeal mask is plugged into the mouth of a patient with a difficult airway, the laryngeal mask cannot deform due to excessive softness when being subjected to certain force, and is conveniently placed to the correct position to play a role.

The body 2 divide into the anterior canal 21 of ventilating and ventilates the back tube 22 two sections, and ventilate anterior canal 21 and cover bag 1 and link to each other, imbed elastic metal wire 6 in the anterior canal 21 of ventilating, and elastic metal wire 6 is the spiral and winds the form, it is concrete, when filling in the laryngeal mask, medical personnel can carry out the application of force to body 2 front end, thereby only need in ventilating anterior canal 21 set up elastic metal wire 6 can, the material has been practiced thrift to a certain extent, simultaneously, the spiral winds the form arrangement mode and makes body 2 possess when filling in the axial compare stronger resistance to deformation ability with before, the practicality is good.

The front ventilation pipe 21 and the rear ventilation pipe 22 are fixedly connected through connection, specifically, a small opening is formed in one end of the front ventilation pipe 21, the small opening is inserted into a larger caliber which is formed in one end of the rear ventilation pipe 22 to be connected, the front ventilation pipe and the rear ventilation pipe are bonded, and no edge exists on the surface of the joint.

One end of the inflation tube 3 is sequentially connected with an indicating air bag 4 and a one-way valve 5, and particularly, the cover bag 1 and the indicating air bag 4 can be inflated or deflated through the one-way valve 5, so that air leakage is effectively avoided.

The mask bag 1 and the tube body 2 are made of silica gel with the Shore hardness of 0-15, and particularly, materials with proper hardness (such as medical silica gel and the like) are adopted for bonding contact because the mask bag 1 and the tube body 2 are in contact with soft and fragile airway inner wall soft tissues for a long time in the application process, so that scratching and severe discomfort are avoided.

The bending angle of the tube body 2 is 120-135 degrees, and particularly, when a patient lies down, the laryngeal mask is placed into the tube body, so that the air inlet of the tube body 2 can be kept in an upward state to the maximum extent, and operation of medical staff is facilitated.

The back side of the cover bag 1 is provided with the foamed medical silica gel skin 11, and particularly, the foamed medical silica gel skin 11 reduces the inflation difficulty of the cover bag 1 in inflation and air exhaust.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
