Tracheal catheter with adjustable inner diameter

Abstract

The invention belongs to the field of medical device, and particularly relates to a tracheal catheter with an adjustable inner diameter. The tracheal catheter comprises a patient insertion end and catheter body, the patient insertion end is formed by orderly splicing and fixing multiple catheter pieces and an airbag, and the size of the inner diameter of the patient insertion end can be adjusted by inflating or exhausting through the airbag. Therefore, the tracheal catheter with the adjustable inner diameter is adopted, the inner diameter of the patient insertion end in the tracheal catheter can be adjusted according to the condition of the patient, the time for selecting the model of the tracheal catheter by medical personnel is greatly shortened, the difficulty of intubation is reduced,and the supply of oxygen and the smooth removal of airway secretions are guaranteed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a trachea tube with adjustable inner diameter. Background technique [0002] Endotracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis. It is an important technique to ensure unobstructed airway, effective ventilation and oxygen supply and avoid aspiration in emergency and general anesthesia. At present, most medical staff choose the type of endotracheal tube according to their age, which not only consumes the rescue time easily, but also the glottis or trachea of ​​each patient is different, and it is impossible to adjust the inner diameter of the endotracheal tube according to the patient's condition during clinical operation . At the same time, if the endotracheal tube is too thin, it cannot guarantee the oxygen supply and the clearance of airway secretions, and if it is too thick, it may easily cause damage to...

Problems solved by technology

At present, most medical staff choose the type of endotracheal tube according to their age, which not only consumes the rescue time easily, but also the glottis or trachea of ​​each patient is different, and it is impossible to adjust the inner diameter of the endotracheal tube according to the patient's condition during clinical operation

At the same time, if the endotracheal tube is too thin, it cannot guarantee the oxygen supply and the clearance of airway secretions, and if it is too thick, it may easily cause damage to the glottis and tracheal mucosa and make it difficult to pass through the stenosis, which brings great challenges to medical staff and great pain to patients.
