Drainage type laryngeal mask

Abstract

The invention provides a drainage type laryngeal mask which can prevent stomach secretions from entering a trachea. The drainage type laryngeal mask is provided with a laryngeal mask component and a drainage component which is arranged on the laryngeal mask component along the extending direction of the laryngeal mask component, wherein the laryngeal mask component is provided with a mask bag body, a connecting pipe body and an air source connector; the connecting pipe body is connected with the mask bag body and the air source connector is connected with the connecting pipe body; the mask bag body is provided with an airbag and an airbag connector which is enclosed by the airbag and is used for connecting the airbag and the connecting pipe body; the airbag comprises a front surface bag part and a back surface bag part; the front surface bag part covers the periphery of the trachea; the back surface bag part is positioned on the opposite side of the front surface bag part and covers a throat wall; the outer surface of the back surface bag part is more outwards convex than the outer surface of the airbag connector; the drainage component is provided with a drainage pipe and a ball bag arranged at an inserting end of the drainage pipe; a groove is respectively formed in the surface of each of the mask bag body, the connecting pipe body and the air source connector; when the mask bag body, the connecting pipe body and the air source connector are connected together, the grooves are communicated with one another, and the drainage pipe is continuously arranged in the grooves which are communicated with one another.

Description

technical field [0001] The invention relates to a laryngeal mask, in particular to a drainage type laryngeal mask. Background technique [0002] In the medical field, the laryngeal mask is inserted into the patient's larynx through the mouth to establish an artificial airway for the patient and assist breathing. It is usually used in general anesthesia operations and is an important medical item commonly used in emergency work and respiratory management. [0003] As the basic design of this type of medical supplies, the laryngeal mask is composed of a mask capsule. The mask capsule has an airbag and an airbag connector, and the airbag seals the throat of the human body. The purpose is to better seal and ensure breathing during use. The patient's oxygen delivery status reached the optimal state. [0004] But for this laryngeal mask, the airbag joint usually protrudes from the airbag, and the airbag does not completely cover the circumferential surface of the airbag joint, or...

AI Technical Summary

Problems solved by technology

[0004] But for this laryngeal mask, the airbag joint usually protrudes from the airbag, and the airbag does not completely cover the circumferential surface of the airbag joint, or the upper surface of the airbag is lower than the circumferential surface of the airbag joint, so that when the larynx is sealed by the airbag , because the upper surface of the airbag is lower than the circumferential surface of the airbag connector, the airbag connector is closely attached to the larynx, thus affecting the sealing of the laryngeal mask to the larynx and increasing the risk of gastric secretions entering the trachea
