Abstract

A laryngeal mask breather tube apparatus comprises a breather tube (1), a drainage tube (2), and a hollow mask bag (3) with an opening at the bottom. A bottom end of the hollow mask bag (3) is connected to the breather tube (1) and the drainage tube (2). A front end of the hollow mask bag (3) is provided with a drainage port (3a) in fluid communication with the drainage tube (2). A ventilation port (3b) in gas communication with the breather tube (1) is disposed in the hollow mask bag (3). The hollow mask bag (3) is of an integrated structure formed by one-time operation and comprising an inflatable back mask (31), a drainage tube (32) in the mask, and an inflatable sleeve bag sealing piece (33). The drainage port (3a) is in fluid communication with the drainage tube (2) through the drainage tube (32) in the mask. Also provided is a method for manufacturing the laryngeal mask breather tube apparatus. The laryngeal mask breather tube apparatus and the manufacturing method therefor can reduce rugged burrs, simplify the production process and improve the production efficiency.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a laryngeal mask ventilation tube device and a manufacturing method thereof. Background technique [0002] Assisted breathing ventilation is a necessary means for assisted breathing to maintain the patient's hemodynamic stability during general anesthesia surgery. Laryngeal mask ventilation is a common way of assisted breathing ventilation, and laryngeal mask ventilation is necessary equipment. [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,...
