Comfortable-to-use irritation-reduction trachea cannula

Abstract

The invention discloses a comfortable-to-use irritation-reduction trachea cannula, which comprises a main cannula, fixed sleeve bags, a lower absorption sleeve, an air injection tube and a lower absorption tube, wherein the appearance of the main cannula simulates the structure of the respiratory tract; the main cannula is made of flexible materials; at least two fixed sleeve bags are arranged on the main cannula; all of the fixed sleeve bags are communicated; the fixed sleeve bags are connected with the air injection tube; the insertion end of the main insertion tube is provided with the lower absorption sleeve; and the lower absorption sleeve is connected with the lower absorption tube. The comfortable-to-use irritation-reduction trachea cannula has the advantages that the irritation on the trachea is small; and the conditions of tracheal mucosa avascular necrosis and cough cannot easily occur; the insertion end of the main cannula is provided with the lower absorption sleeve; secreta generated on the trachea inner wall near an air flow hole can be absorbed and can be discharged out of the body through the lower absorption tube; secreta in the respiratory tract can be continuously cleared; and the occurrence of the catheter blockage condition is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tracheal intubation tube that is comfortable to use and reduces irritation. Background technique [0002] Endotracheal intubation is the most effective and reliable method to establish an artificial airway. It refers to the technique of inserting a special tracheal tube through the oral cavity or nasal cavity and into the trachea through the glottis. This technique can relieve the airway. Provide the best conditions for preventing obstruction, ensuring airway patency, clearing respiratory secretions, preventing aspiration, and assisting or controlling breathing. Endotracheal intubation is an important rescue technique commonly used in emergency work. It is one of the most widely used, most effective and fastest means in respiratory management. It is a basic skill that medical personnel must master proficiently. to a vital role. And it can suck out secretions or foreig...
