Problems solved by technology

However, there is at least one glue bonding process in the mask made by this method, and uneven burrs may be produced, and the molding and assembly process can be simplified, while achieving better performance of the laryngeal mask
[0005] The U.S. Prior Patent Publication No. US7806119 (B2) discloses an airway management device without an inflatable cuff, which is made of a single piece of elastomeric material with a Shore hardness of 0-30 in a specific shape. The mask body does not need to be inflated, and the seal to the throat is formed by the prefabricated shape and soft elastic body. Although this structure can be placed quickly without inflation, the sealing performance of the throat is still to be determined due to the limited range of contraction of the elastic body. increase, the cost of materials is also higher

Embodiment 1

[0028] Please refer to figure 1 and Figure 4 , the novel laryngeal mask ventilation device includes a hollow mask body 1 and a connecting tube 2 .

[0029] The hollow cover body 1 includes a cover part 11 with an open bottom and a back part 12 located on the top of the cover part 11 and supporting the cover part 11 . The mask portion 11 is a flexible annular sheet structure, thereby achieving better sealing performance. During the process of placing the new laryngeal mask ventilator on the larynx, the flexible annular The sheet can be moderately contracted and extended under the action of pressure and space. It can seal the throat without inflating and adjusting the size, and has a better sealing effect. The annular sheet is a container structure with an opening that extends inwardly to form a radian. The lower edge of the annular sheet is extended to form the sealing structure 1a, thereby improving the sealing performance. The extension direction of the sealing structure...

Abstract

A laryngeal mask airway device comprises a hollow mask body (1) and a connection tube (2). The hollow mask body (1) comprises a cover portion (11) open at the bottom, and a back portion (12) located at a top portion of the cover portion (11) and supporting the cover portion (11). A distal end of the back portion (12) is provided with a connection hole (a) connected to a proximal end of the connection tube (2). The cover portion (11) is a flexible ring-shaped sheet structure. The back portion (12) is a support structure more rigid than the cover portion (11). The laryngeal mask airway device does not need to be inflated, has a smaller outer diameter, can reduce stimulation to the larynx mucosa, and also enables a better seal and ventilation efficiency.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a novel laryngeal mask ventilation device. Background technique [0002] Assisted breathing ventilation is a necessary means for assisted breathing for surgical patients during general anesthesia operations to maintain the hemodynamic stability of patients under general anesthesia. Laryngeal mask ventilation is a common way of assisted breathing ventilation. device of. [0003] The promotion and use of the laryngeal mask is to overcome the shortcomings of difficult intubation operation and easy to cause sensitive reactions in the tracheal intubation ventilation method, to achieve simple and convenient ventilation operation and to reduce the damage to the patient's throat and respiratory mucosa. The prior art has disclosed the basic structure of the laryngeal mask, which mainly includes components such as a mask body, a ventilation tube, a drainage tube, a dental pad, an inflat...
