Real-time pressure monitoring tracheal intubation device with suction function and method of real-time pressure monitoring tracheal intubation device

Abstract

The invention discloses a real-time pressure monitoring trachea cannula device with a suction function and a method of the real-time pressure monitoring trachea cannula device. The trachea cannula device comprises an endotracheal catheter, a constant-pressure inflating and deflating device and an anti-blocking drainage tube. A first opening communicated with the air passage is formed in the side wall of the cannula located above the cuff, a second opening communicated with the outside is formed in the side wall of the cannula located outside the human body, and a drainage channel located in the cannula is connected between the first opening and the second opening; the anti-blocking drainage tube comprises a drainage end and a suction end, and the anti-blocking drainage tube can extend into the drainage channel through the second opening, so that the drainage end is arranged between the cannula and the airway through the first opening; the suction end is located outside the human body and can be connected with a suction device so that secretions in the air channel above the cuff can be sucked and emptied through the drainage end. Secretions in the airway above the cuff are sucked and emptied regularly through the drainage end, and pulmonary infection caused by the fact that the secretions in the airway penetrate into the trachea can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a real-time pressure monitoring endotracheal intubation device with a suction function and a method thereof. Background technique [0002] Endotracheal intubation is a method of inserting a special endotracheal tube through the oral cavity or nasal cavity and into the trachea or bronchus through the glottis to provide the best conditions for unobstructed airway, ventilation and oxygen supply, and airway suction. It is the first choice for rescuing patients with respiratory dysfunction. important measure. Endotracheal tubes generally consist of a tube and a cuff. Under normal circumstances, the pressure range of the cuff is generally 25-30mmHg. If it is too high, it will easily lead to hypoxia, ischemia and even necrosis of the tracheal wall mucosa. If it is too low, it will not be able to effectively close the gap between the cuff and the trachea. It is ther...

AI Technical Summary

Problems solved by technology

At present, in clinical practice, the pressure of the cuff is usually detected every 4 hours with a manometer, and the cuff leakage or even rupture cannot be detected in time.

In addition, in the current clinical practice, especially for patients who are bedridden for a long time in the intensive care unit and use a ventilator, it is easy for secretions such as saliva to flow into the trachea. When there is a gap between the cuff and the trachea due to other reasons, the secretion will penetrate into the trachea, which will easily lead to lung infection, increase the difficulty of treatment and the medical burden of patients and society

Facing the above major clinical needs, in view of the fact that the current endotracheal intubation device cannot monitor the cuff pressure in real time and has no drainage function, a solution for endotracheal intubation with real-time pressure monitoring and suction function is proposed
