Tracheal tube for secretion removal

Abstract

A tracheal tube with secretion removal includes an airway tubular body, an inflatable cuff disposed on the airway tubular body, a suction conduit. A plurality of spaced projection structures are arranged on the outer periphery of the secretion removal portion of the tracheal tube, and the projection structures match with each other to define a plurality of spaced secretion removal grooves, and communicating groove communicating the secretion removal grooves. The suction conduit is fixed on the tracheal tube in such a manner of communicating with the secretion removal grooves. Through the projection structures on the periphery of the secretion removal portion to form communicating secretion removal grooves and the communicating groove. Based on the structural design of the suction tube, the tracheal tube can be used incorporation with a respirator for assisting breathing, and sucking accumulated sputum and saliva. The tracheal tube may not be blocked due to sucking soft tissue or mucosa, thereby increasing the sucking capability.

Description

Technical field [0001] The invention relates to a ventilation tube, in particular to an artificial airway inserted in the trachea and having the function of sucking and removing sputum, saliva and other liquids. Background technique [0002] Many patients with long-term respiratory failure need to use a respirator for ventilation in order to maintain their daily functions. For patients using invasive respirators, an additional artificial airway needs to be installed in the trachea to effectively use the respirator. Artificial airway is divided into endotracheal tube or tracheal tube, both of which have a balloon structure. After the patient is inserted into the tracheal tube or endotracheal tube, the balloons of the tracheal tube and endotracheal tube will block the The inner wall of the trachea often causes the patient’s sputum and saliva to accumulate in the trachea above the air sac, and the accumulated sputum and saliva will leak from the tracheal incision and contaminate the...

AI Technical Summary

Problems solved by technology

[0003] In general sputum suction operations, a sputum suction tube connected to a suction device is inserted from the gas incision or nostril to the upper part of the air bag for sputum suction. The opening at the end of the sputum tube is often blocked by sucking soft tissue. In addition to causing inconvenience in the suction operation, it is also easy to cause injury to the sucked tissue due to the strong suction of the sputum tube. Therefore, the current use of The artificial airway really needs to be improved
