Embodiment Construction

[0023] Embodiments of the present invention are described in detail below:

[0024] Such as Figure 1 to Figure 6 As shown, a laryngeal mask includes a mask body 10 and a soft rubber cover 20. The cover surface of the mask body 10 is provided with a main vent 11, and both sides of the mask body 10 are provided with side wings 12. On the first side of the mask body 10 The end 13 is respectively provided with the main vent hole, the inflation hole, the first discharge hole and the first negative pressure hole, and the second end 14 of the cover body 10 is respectively provided with the second discharge hole and the second negative pressure hole, and the first discharge hole 1. The first negative pressure hole communicates with the second discharge hole and the second negative pressure hole respectively, and the main vent hole communicates with the main vent 11; the soft rubber cover 20 is set on the cover 10, and the main vent 11 of the cover 10 , the first end 13 and the secon...

Abstract

The invention discloses a laryngeal mask which comprises a mask body and a soft rubber mask sleeve; a main vent opening is formed in the mask surface of the mask body; side wings are arranged on the two sides of the mask body; a main vent hole, an inflation hole, a first drain hole and a first negative pressure hole are formed at the first end of the mask body; a second drain hole and a second negative pressure hole are formed at the second end of the mask body; the first drain hole and the first negative pressure hole are respectively communicated with the second drain hole and the second negative pressure hole; the main vent hole is communicated with the main vent opening; the soft rubber mask sleeve is sleeved on the mask body; and the main vent opening, the first end and the second end of the mask body are exposed. With the adoption of the structure, the laryngeal mask has the beneficial effects that the laryngeal mask can be simultaneously used as an inflatable laryngeal mask and a non-inflatable laryngeal mask, the universality is strong, and the processing cost is reduced.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a laryngeal mask. Background technique [0002] In clinical anesthesia, first aid or resuscitation, it is necessary to quickly establish a smooth breathing channel. The existing laryngeal mask has two structures: an inflatable laryngeal mask and a non-inflatable laryngeal mask. Both types of laryngeal masks have their own advantages and disadvantages. [0003] In the processing process, the processing molds of the existing inflatable laryngeal mask and the non-inflatable laryngeal mask are independent of each other, the commonality between the two products is poor, and the processing cost is high. Contents of the invention [0004] Based on this, the present invention overcomes the defects of the prior art and provides a laryngeal mask. The structure of the present invention can be used for both inflatable and non-inflatable laryngeal masks, which has strong versatility and r...
