Air-exhaust-free tracheal catheter and use method thereof

Abstract

The invention discloses an air-exhaust-free tracheal catheter. The air-exhaust-free tracheal catheter is characterized by comprising a tracheal catheter body, an air bag, an inflation valve and an inflation tube, wherein two ends of the tracheal catheter body are provided with a tracheal catheter connector and a tracheal catheter opening, the air bag is arranged near the tracheal catheter opening, after swelling, and the air bag is inverted-hopper-shaped, and is adaptive to the hypolarynx weasand in shape. According to the air-exhaust-free tracheal catheter, the air bag adaptive to the hypolarynx weasand in shape is designed, after swelling, the air bag completely isolates the weasand above and below the air bag, while when the weasand extubation operation is carried out, the air exhausting operation for the air bag is not needed, by utilizing the feature that the upper end of the air bag is thin and the lower end of the air bag is thick, the glottis is enlarged slowly, then the tracheal catheter is pulled out, then secretions of the pharynx oralis above the air bag and the gastroesophageal reflux contents are removed, and the pulmonary infection, bronchic blockage, pulmonary atelectasis and the like caused by the reason that the secretions of the pharynx oralis and the gastroesophageal reflux contents move downwards are eliminated; and the inverted-hopper-shaped air bag is also applicable to the main air bag of a double-cavity bronchial catheter.

Description

technical field [0001] The invention relates to the field of medical aids, in particular to a suction-free tracheal tube. Background technique [0002] The endotracheal tube is one of the essential tools for establishing an artificial airway during anesthesia and first aid. The existing endotracheal tube is filled with an air bag after insertion to fix the position of the endotracheal tube and seal it to prevent air leakage. However, after the endotracheal tube is placed, there is still a large gap between the endotracheal tube and the glottis, through which oropharyngeal secretions and gastroesophageal reflux can easily flow into the subglottis and stay in the air bag of the endotracheal tube. in the upper trachea. When the endotracheal tube is pulled out, although the oropharynx and the trachea are suctioned, the secretions accumulated in the trachea from the glottis to the endotracheal tube balloon cannot be directly sucked. The secretions in the trachea above the air b...

AI Technical Summary

Problems solved by technology

When the endotracheal tube is pulled out, although the oropharynx and the trachea are suctioned, the secretions accumulated in the trachea from the glottis to the endotracheal tube balloon cannot be directly sucked. The secretions in the trachea above the air bag will instantly flow into the trachea below the air bag. Although a suction tube can be inserted through the lumen of the endotracheal catheter for suction, it cannot be completely sucked out. Pulmonary infection, bronchial blockage, atelectasis, etc. seriously affect the cure of patients. Patent 201511003467.2 introduces a suction-free tracheal tube with an inflatable body, which prevents secretions from descending. However, this device When pulling out, the expansion body needs to be contracted, causing a part of the secretion to still enter the deep part of the trachea and even the bronchi
