Example Embodiment

[0024] The present invention will be further described below in conjunction with the specific embodiments in the drawings.

[0025] Refer to Figure 1-3 As shown, a self-regulating cuff tracheal intubation device of the present invention includes a tracheal intubation tube 2 with an intubation cuff 1, wherein one end of the tracheal tube 2 is placed in the patient’s trachea through the mouth or nose of the patient The other end is connected with related equipment such as a ventilator or anesthesia machine. The intubation cuff 1 is sleeved on the periphery of the tracheal intubation tube 2 and is attached to the patient’s tracheal wall. The two are trachea with mutually independent airways. Independent air supply, the tracheal intubation tube 2 is not limited to one or more of the disposable intubation and the disposable reinforced intubation. In practical application, the intubation cuff 1 can be fixed on the patient’s trachea after inflation To prevent it from sliding, the trac...

Abstract

The invention discloses a cuff endotracheal intubation device with self-stabilizing pressure, which comprises an endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotracheal endotrachea The middle part of the cannula is provided with an air supply assembly that communicates with it and can inflate the intubation cuff, and the end of the cannula is also equipped with an automatic air supply or suction to the intubation cuff so that The intubation cuff maintains a pressure-balanced regulated system. The invention provides a pressure-stabilizing cuff endotracheal intubation device. The pressure of the intubation cuff is maintained within the tolerance range of the human body through the pressure stabilization system, and the intubation cuff is always attached to the patient's trachea wall. Patients who need long-term intubation due to long operation time can ensure the safety of operation patients.

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...
