Medical laryngeal mask airway

Abstract

The invention relates to a medical laryngeal mask airway, in particular to a laryngeal mask airway sleeve capsule which can be used for clinical anesthesia or used after a tube is inserted into a trachea during emergency treatment. The medical laryngeal mask airway comprises a tube body, wherein a sleeve capsule is arranged near an opening at the front end of the tube body; a bulge is formed on the top of the sleeve capsule and is connected with an inflation catheter; one end of the inflation catheter is communicated with the sleeve capsule, and the other end of the inflation catheter is connected with a connection fixing sleeve; the connection fixing sleeve comprises an extrusion type inflation capsule and a fixing sleeve; a check valve is arranged in the fixing sleeve; the inflation catheter is also provided with a branch tube; and the branch tube is connected with a pressure detection and air leakage device. The medical laryngeal mask airway has a reasonable structure, the original air sac of the laryngeal mask airway is improved, and the inflation part of the air sac is modified in a mode that a one-way (outlet) air valve is arranged close to a catheter end and a one-way (inlet) air valve is arranged at the inflation end; and the air sac is only required to be extruded by a hand after the tube is inserted into the trachea, so that air flows into the sleeve capsule at the front end of the catheter. The pressure measurement and air leakage device is arranged at one end of the original air sac close to the catheter. The medical laryngeal mask airway is convenient to operate and is time-saving and labor-saving, so that opportunity is provided for emergency treatment of patients.

Description

technical field [0001] The invention relates to a medical laryngeal mask, in particular to a laryngeal mask cuff which can be used after successful tracheal intubation during clinical anesthesia or first aid, and belongs to the technical field of medical devices. Background technique [0002] During clinical anesthesia or first aid, proper cuff pressure of the laryngeal mask can avoid tracheal mucosal injury and reduce complications of artificial airway mechanical ventilation. After successful tracheal intubation, the cuff of the endotracheal tube needs to be inflated, and the cuff of the endotracheal tube needs to be kept at an appropriate pressure (150-250 mm of water column) to avoid damage to the tracheal mucosa and reduce complications of artificial airway mechanical ventilation. At present, in clinical anesthesia or first aid work, after successful endotracheal intubation under general anesthesia, it is necessary to inflate the endotracheal tube cuff with a disposable ...

AI Technical Summary

Problems solved by technology

At present, in clinical anesthesia or first aid work, after successful endotracheal intubation under general anesthesia, it is necessary to inflate the endotracheal tube cuff with a disposable syringe prepared in advance through the balloon, which is cumbersome and increases the cost of syringe consumables. The pressure in the cuff cannot be measured, it is only judged by the doctor's experience and feeling, and the safety is not high
