Airway operation laryngeal mask

Abstract

The invention discloses an airway operation laryngeal mask which comprises a thin laryngeal mask catheter and a laryngeal mask body, the laryngeal mask catheter is used for being placed into the oropharyngeal cavity of a patient through a mouth tooth part, the laryngeal mask body surrounds the outside of the glottis of the patient during use, and a ventilation connector and an operation one-way valve are arranged at the tail end of the laryngeal mask catheter. The airway operation laryngeal mask can be connected with a breathing tube in a matched mode through the ventilation connector, an operation tool can be placed in by operating the one-way valve, sealing performance can be guaranteed, various operations can be carried out on the airway, and meanwhile mechanical ventilation is carriedout. The ventilation connector is provided with a filter membrane sleeve in the cavity of the laryngeal mask catheter, and breathing gas can be filtered. The airway operation laryngeal mask is simplein structure, low in cost, capable of filtering breathing gas during ventilation, capable of implementing endotracheal surgery, safe and reliable.

Description

technical field [0001] The invention relates to a laryngeal mask, which belongs to the technical field of the laryngeal mask. Background technique [0002] The laryngeal mask has little irritation to the airway, is easy to tolerate, is not prone to airway damage, and has reliable ventilation effect. It is one of the important airway management tools in general anesthesia. [0003] However, the laryngeal mask cannot meet the surgical needs in many occasions, such as: [0004] 1. During the removal of tracheal foreign bodies, the ventilation needs to be interrupted during the operation, which often leads to a decrease in the partial pressure of oxygen in the patient during the operation, and even severe hypoxemia, which increases the risk of the operation for the patient. The foreign body is often broken when taken out. At this time, it is necessary to insert the forceps into the airway several times, and then withdraw the foreign body fragments before withdrawing from the en...

AI Technical Summary

Problems solved by technology

The extraction forceps are inserted and withdrawn from the airway many times, which brings great inconvenience to the operator, greatly prolongs the operation time and increases the damage of the airway

[0005] 2. During interventional surgery for intratracheal tumors, it is necessary to insert surgical tools such as electric knife and electrocoagulation through the mouth of the laryngeal mask. At this time, the ventilation is interrupted, which greatly increases the risk of hypoxia for patients

The increased risk of hemorrhage in the airway is extremely high, and thrombosis is easily formed in the small airway, leading to alveolar closure, and even partial atelectasis, which seriously reduces the lung function of the patient

[0006] 3. The clinical anesthesia work is extremely busy, and the expensive medical equipment of the anesthesia machine is basically impossible to be sterilized after a single operation, resulting in a greatly increased risk of cross-infection

At present, the respiratory filter is connected to the mouth of the threaded tube in clinical practice. The relatively bulky threaded tube brings greater traction force to the endotracheal tube, which increases the risk of prolapse of the endotracheal tube; at the same time, the busy clinical work makes the breathing filter forget to use it. If it happens, it will greatly increase the risk of cross-infection of the respiratory tract
