Problems solved by technology

For the positioning problem when inserting the laryngeal mask, there is currently no very effective solution
In view of the need to fix the laryngeal mask after the laryngeal mask is inserted, adhesive tape is usually used to fix the laryngeal mask on the face in clinical practice to prevent the laryngeal mask from shifting, but its fixing ability is essentially very limited
For example, clinically, when the patient’s body position changes due to factors such as surgical operations, such as lying on his side or turning over, the problem of decreased ventilation function due to the displacement of the laryngeal mask will still occur, and even endanger the patient’s life in severe cases

Embodiment Construction

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the drawings are not drawn in actual scale, and the proportions of some components are enlarged. In addition, in the description of the following embodiments and the drawings, the same reference numerals are attached to the same components, and overlapping descriptions will be omitted.

[0020] refer to Figure 1 to Figure 3 , in an exemplary embodiment according to the present invention, the laryngeal mask 1 may include: a laryngeal mask ventilation tube 11 ; a mask capsule 13 coupled to the lower end of the laryngeal mask ventilation tube 11 ; an applicator 17 coupled to the laryngeal mask ventilation tube 11 of the outer surface.

[0021] The mask body 13 can be formed of an elastic material with a hardness of 45-50°, and the elastic material has good flexibility, so that the airway of the human body will not be damaged whe...

Abstract

The invention provides a laryngeal mask airway. The laryngeal mask airway comprises a laryngeal mask airway tube (11) and an application (17), wherein the application (17) is connected to the upper end of the laryngeal mask airway tube (11) and comprises a connecting part (171) tightly surrounding the outer surface of the laryngeal mask airway tube (11) and an attaching part (172) extending outwards from the periphery of the connecting part (171), and the attaching part (172) is used for being directly attached to human skin to prevent the laryngeal mask airway from displacement. The laryngeal mask airway can be effectively prevented from displacement, so that the laryngeal mask airway can be positioned and fixed better.

Description

technical field [0001] The invention relates to a laryngeal mask, which belongs to the field of medical instruments. Background technique [0002] There are many types of laryngeal masks used for anesthesia, and their main function is to establish an artificial airway. When the laryngeal mask is placed in the human body, it is usually necessary to consider the positioning of the laryngeal mask when it is placed and the fixation after the laryngeal mask is placed. For the positioning problem when inserting the laryngeal mask, there is currently no very effective solution. In view of the need to fix the laryngeal mask after the laryngeal mask is inserted, adhesive tape is usually used to fix the laryngeal mask on the face in clinical practice to prevent the laryngeal mask from shifting, but its fixing ability is essentially very limited. For example, clinically, when the patient's body position changes due to factors such as surgical operations, such as lying on his side or ...
