Inflation-free sputum suction type intubation laryngeal mask

Abstract

The invention relates to an inflation-free sputum suction type intubation laryngeal mask which comprises a mask body and a mask body tube. The mask body comprises a mask body base plate and a main mask body; the center region inside the main mask body is provided with a mask body cavity which can be communicated with the mask body tube, and a directional guiding body communicated with the mask body tube is arranged inside the mask body cavity; the inflation-free sputum suction type intubation laryngeal mask further comprises an airway instrument sealing valve arranged inside the head end of the mask body tube, an airway instrument can penetrate through the airway instrument sealing valve to stretch into the mask body tube, and the airway instrument stretching into the mask body tube can beguided by the positioning guiding body and then stretches into the mask body cavity; after the airway instrument penetrates into the mask body tube, the head end of the mask body tube through which the airway instrument penetrates can be sealed by means of the airway instrument sealing valve. In the air supply process, sealing performed after the airway instrument is inserted can be achieved, thecomplexity and using cost of the laryngeal mask can be lowered, the laryngeal mask ventilation sealing effect can be ensured without inflation when the laryngeal mask is in use, secretion suction inthe ventilation process can be achieved, the phenomenon that epiglottis blocks an air way is avoided, and the using stability and reliability are improved.

Description

technical field [0001] The invention relates to an intubation laryngeal mask, in particular to an intubation laryngeal mask of an inflatable sputum suction type, which belongs to the technical field of medical instruments. Background technique [0002] Laryngeal mask, as a medical device used to maintain patients' breathing and ventilation, is widely used in clinical anesthesia, first aid or resuscitation because of its non-invasive airway characteristics. Along with the progress of material and technology, existing multiple improved laryngeal mask is used clinically at present, but the laryngeal mask of prior art still has many problems to exist. [0003] The current laryngeal masks use airbags or soft rubber rings to cover the glottis to achieve a sealing effect. The essence of the seal is that the airbags or soft rubber rings press the throat mucosa surrounding the glottis. The pressure is perpendicular to the pressure of gas leakage, and the sealing effect is poor. , to...

AI Technical Summary

Problems solved by technology

At present, the laryngeal mask used to guide tracheal intubation has serious air leakage during intubation, which affects the effect of respiratory support and brings safety hazards to patients

[0005] Current laryngeal masks cannot effectively suction sputum during respiratory support, and forced suction often leads to air leakage and throat friction damage

The laryngeal masks that are widely used clinically are all air bag type, which require high pressure on the air bag when in use, and need to be inflated and deflated, which is cumbersome to use
