Trachea cannula for airway operation

Abstract

The invention discloses a trachea cannula for airway operation. The trachea cannula comprises an outer cannula used for being implanted into the trachea of a patient through the glottis, and an innercannula arranged in the outer cannula in a matching and sleeved manner and used for connecting breathing equipment; the outer cannula is provided with a pressure bladder, an inflation tube and an inflation valve port; the tail part of the inner cannula is provided with a breathing connecting tube and an operation one-way valve; and the breathing connecting tube is provided with a filter membrane sleeve in an inner cannula cavity. The inner cannula and the outer cannula are used in a mating manner, so that breathing of the patient can be supported, cross infections are reduced, airway operationcan be implemented during ventilation, and the inner cannula can be replaced during sputum blockage, and the tracheotomy rate is reduced. The trachea cannula has a simple structure, high practicability and high safety.

Description

technical field [0001] The invention relates to a tracheal tube, which belongs to the technical field of tracheal tubes. Background technique [0002] The endotracheal tube has a good airtight seal and reliable ventilation effect, and is one of the important airway management tools in general anesthesia. [0003] However, endotracheal tubes cannot meet the surgical needs in many situations, 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 endotracheal tube. Repeated interruption of breathing greatly increase...

AI Technical Summary

Problems solved by technology

[0011] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an airway operation tracheal cannula, which can effectively control the depth of the tracheal intubation, avoid the intubation being too deep or too shallow, and allow synchronous ventilation during airway surgery , avoid hypoxia, can ensure the use of respiratory gas filtration, reduce cross-infection, and when the inner wall of the ventilation tube is blocked, it can conveniently solve the problem of blockage, keep the inner cavity of the breathing tube unobstructed at any time, and reduce the risk of tracheotomy
