New intubating laryngeal mask

Abstract

The invention discloses a new intubating laryngeal mask which can be applied as a laryngeal mask and can be seamlessly switched to an application state of a trachea intubation. The new intubating laryngeal mask comprises a laryngeal mask body (2) and the trachea intubation (3) of a soft cover part (1), a gas charging tube (4) is connected with the soft cover part (1), an intubation tube (5) is arranged on the laryngeal mask body (2), a laryngeal mask cavity (6) is formed on the laryngeal mask body (2) and located in the place surrounding the soft cover part (1), the intubation tube (5) is communicated with the laryngeal mask cavity (6), the trachea intubation (3) is sealed and fitted in a sliding mode in the trachea intubation (5), when the trachea intubation (3) is pushed, the outlet end of the trachea intubation (3) moves to the laryngeal mask cavity (6) and passes through the opening of the laryngeal mask cavity (6), and the trachea intubation (3) and the intubation tube (5) are kept sealed. The new intubating laryngeal mask can be applied to the field of medical devices.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a novel intubation laryngeal mask. Background technique [0002] The laryngeal mask is an effective means to establish a safe airway in general anesthesia. As the use of laryngeal masks has become more and more widespread, the technology of laryngeal masks has also undergone rapid changes. So far, a variety of laryngeal masks of different models and types have been developed and supplied to clinical applications. Before the laryngeal mask, when performing general anesthesia, tracheal intubation is required to ensure the patient's lung breathing function. Compared with tracheal intubation, the application of laryngeal mask has incomparable advantages: (1) It is easy to use and can quickly establish an artificial airway; (2) The success rate of placement is high, and the success rate of untrained medical staff is also extremely high. High; (3) Reliable ventilation; (4) Avoid thr...

AI Technical Summary

Problems solved by technology

When the existing laryngeal mask is changed from laryngeal mask ventilation to endotracheal intubation, it is necessary to remove the laryngeal mask before performing endotracheal intubation. The specially designed intubation laryngeal mask also needs to suspend ventilation and insert the endotracheal intubation through the vent port, and then pass The placed tracheal intubation will be fed with oxygen. During this process, mechanical ventilation will not be available temporarily. If the ventilation is suspended for too long, the risk of hypoxia may occur
