Cuff tracheal intubation device with automatic pressure stabilizing function

Abstract

The invention discloses a cuff tracheal intubation device with an automatic pressure stabilizing function. The cuff tracheal intubation device comprises a tracheal cannula with a cannula cuff. A sleeve which is communicated with the cannula cuff is arranged on the tracheal cannula, an air supply assembly which is communicated with the sleeve is arranged in the middle of the sleeve, the cannula cuff can be inflated by the air supply assembly, a pressure stabilizing system is further arranged at the tail end of the sleeve, air can be automatically supplied for the cannula cuff by the pressure stabilizing system, or air can be sucked from the cannula cuff by the pressure stabilizing system, so that the pressures of the cannula cuff can keep balanced. The cuff tracheal intubation device with the automatic pressure stabilizing function has the advantages that the pressures of the cannula cuff can be maintained in the tolerant ranges of human bodies by the pressure stabilizing system, the cannula cuff always clings to the walls of the tracheas of patients, accordingly, the cuff tracheal intubation device is applicable to the patients with long-time intubation requirements due to long surgery time, and the life safety of the surgery patients can be guaranteed.

Description

technical field [0001] The invention relates to the field of medical instruments, more specifically, it relates to a cuff endotracheal intubation device with self-stabilizing pressure. Background technique [0002] Endotracheal intubation is one of the most widely used, effective and rapid tools in airway management. Endotracheal intubation through the glottic fissure into the trachea can provide the best conditions for unobstructed airway, ventilation and oxygen supply, and prevention of aspiration, which plays a vital role in saving the lives of patients and reducing the mortality rate. During the use of endotracheal intubation, sputum in the patient's body is likely to be stored above the intubation cuff. If there is a gap between the cuff and the patient's tracheal wall, sputum will easily enter the lungs along the gap, causing ventilator-associated pneumonia. If the operation time is long or the catheter needs to be placed for a long time, the cuff will compress the tr...

AI Technical Summary

Problems solved by technology

If the operation time is long or the catheter needs to be placed for a long time, the cuff will compress the tracheal wall. When the pressure is too high, it may block the blood supply of the local mucosa, resulting in mucosal necrosis, tracheal stenosis, deformation, and even tracheoesophageal fistula and other complications.
