Silicone steel wire reinforcement type trachea cannula directly connectable with end-tidal CO2 monitoring

Abstract

The invention discloses a silicone steel wire reinforcement type trachea cannula directly connectable with end-tidal CO2 monitoring. The trachea cannula comprises a main trachea, the upper end of themain trachea is fixedly connected with a connector, the position, close to the bottom end, of the outer surface of the main trachea is fixedly connected with a cuff, the position, close to the connector, of the outer surface of the main trachea is fixedly connected with a high-pressure trachea and a gas hose, the high-pressure trachea is located on one side of the gas hose, one end of the high-pressure trachea is connected with the cuff, the other end of the high-pressure trachea is fixedly connected with an indicating airbag, and the outer surface of the upper end of the indicating airbag isfixedly connected with a valve. Compared with elbows connected with the end-tidal CO2 monitoring, the silicone steel wire reinforcement type trachea cannula directly connectable with end-tidal CO2 monitoring can significantly reduce dead space gas volume, reduce repeated inhalation and decrease respirator assistance or control incidence of hypercapnia of respiration children patients.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a silicone steel wire reinforced tracheal intubation that can be directly connected to end-tidal carbon dioxide monitoring. Background technique [0002] Tracheal intubation refers to the technique of inserting a special endotracheal tube into the trachea through the glottis called tracheal intubation. This technique can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction and prevention of aspiration. , Emergency tracheal intubation technology has become an important measure in the rescue of CPR and critically ill patients with respiratory dysfunction. Tracheal intubation is an important rescue technique commonly used in emergency work. It is one of the most widely used, most effective and quickest methods in respiratory management. It is a basic skill that medical personnel must master. It is effective in rescuing patients’ lives an...

AI Technical Summary

Problems solved by technology

[0005] ② Those who cannot meet the needs of the body's ventilation and oxygen supply and need mechanical ventilation;

[0006] ③ Unable to clear upper respiratory tract secretions, reflux of gastric contents or hemorrhage and aspiration at any time;

[0011] However, the tracheal intubation has the following disadvantages when used: it cannot be directly connected to the end-tidal CO2 monitoring connector, and must be connected to the end-tidal CO2 monitoring connector through the vent hole of the elbow in the ventilator threaded tube set. Intubated mechanically ventilated infants (especially infants under 1 year old) and neonates (especially premature infants), the small elbow greatly increases the dead space during ventilation, aggravating type II respiratory failure or Hypercapnia in children undergoing laparoscopic surgery produces a series of hazards; reason (mechanism): the tidal volume of infants and newborns is very small, the tidal volume is (6-8) ml / kg, and the body weight is 2.5 Take a newborn baby of kg as an example, calculated as 7ml / kg, the tidal volume = 2.5*7 = 17.5ml
