Sputum-suction and medicament-injection trachea cannula, trachea cannula assembly and manufacturing method of trachea cannula

Abstract

The invention discloses a sputum-suction and medicament-injection trachea cannula, a trachea cannula assembly and a manufacturing method of the trachea cannula. The trachea cannula comprises an arc cannula main body, an air bag, two medicament injection bags and a sputum suction tube, wherein medicament injection channels are formed in the wall of the cannula main body, and a containing groove is formed on the wall of the cannula main body and is internally provided with a developing line and the sputum suction tube. The trachea cannula assembly comprises the trachea cannula, a sputum collection component, an air bag inflation component and a medicament injection component. The manufacturing method of the trachea cannula comprises the following steps of: manufacturing the sputum suction tube and a straight tube the wall of which is internally provided with an inflation channel and the medicament injection channels, processing the containing groove and the inlets and outlets of the channels on the wall of the straight tube, and then bending the straight tube to form the cannula main body; and forming bag bodies of the air bag and the two medicament injection bags, combining the bag bodies with the cannula main body, and processing medicament injection holes. By virtue of the trachea cannula assembly, in a process of respiring through a respirator, the procedures of endotracheal anesthesia, cleaning, inflammation diminishing and automatic sputum cleaning can be realized conveniently and timely, and the procedure of sputum sampling can be conducted conveniently.

Description

technical field [0001] The present invention relates to a medical instrument used in tracheal intubation, especially a tracheal intubation with functions of suctioning sputum and injecting medicine, and a tracheal intubation assembly composed of the tracheal intubation and other components, which can achieve the endotracheal Anesthesia, washing, anti-inflammation and collection of sputum samples. technical background [0002] At present, establishing an artificial breathing channel through tracheal intubation is the most effective, mature, and most commonly used technical means for first aid and rescue and nursing of critically ill patients. Endotracheal intubation is a key surgical instrument for establishing an artificial breathing circuit in tracheal intubation surgery, and an essential medical instrument in the process of first aid and rescue and nursing of critically ill patients. [0003] Most of the patients undergoing tracheal intubation are critically ill patients ...

AI Technical Summary

Problems solved by technology

In the process of clearing the patient's sputum and sampling, the mutual contamination between the sputum and the outside world will often cause contamination of the sputum sample, which will affect the accuracy of the sputum analysis.
