Leading-in device for giving tracheal cannula through laryngeal mask

Abstract

The invention relates to a leading-in device for giving a tracheal cannula through a laryngeal mask. A problem that an artificial airway is established for patients with difficulty in tracheal intubation when the laryngeal mask cannot be kept in use for a long time can be effectively solved. First airbags are mounted at the left end of a guide wire; the first airbags are communicated with a second airbag at the right end of the guide wire through airways; the second airbag is communicated with a valve mouth at the right end part of the guide wire; at least three first airbags are arranged and uniformly distributed on the three side walls of the guide wire in the circumferential direction of the guide ire; and the first airbags are communicated with one another through connecting tubes. The leading-in device for giving the tracheal cannula through the laryngeal mask, provided by the invention, is simpler in operation, easier to learn and more time-saving than a fiber bronchoscope when used for transition between the laryngeal mask and the tracheal cannula and is particularly used for patients with difficulty in tracheal intubation; during the transition period, the airways are always kept in an open state through the adoption of the design of the airbags; and the external diameter of the guide wire allows the tracheal cannula with smaller type to be smoothly inserted.

Description

technical field [0001] The invention relates to a medical device, in particular to an introduction device for giving endotracheal intubation through a laryngeal mask. Background technique [0002] At present, there are two common ways to establish an artificial airway in clinical emergency: laryngeal mask and tracheal intubation. Tracheal intubation is generally used, but for patients with difficult intubation, there are more opportunities to use laryngeal mask, but due to structural problems, long-term use of laryngeal mask will cause severe laryngeal edema, and it is not easy to fix, so it needs to be established When artificial airway is used for a long time, endotracheal intubation should still be replaced. When replacing, if the laryngeal mask is pulled out first and then endotracheal intubation is performed, a lot of time will be wasted. And if the endotracheal intubation is unsuccessful, it is still necessary to temporarily replace the laryngeal mask again. Repeated...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an introduction device for endotracheal intubation through the laryngeal mask, which can effectively solve the problem of difficult endotracheal intubation. When the laryngeal mask cannot be kept for a long time, the establishment artificial airway problem
