Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a four-in-one trachea cannula.
Background
The tracheal intubation is a treatment method for relieving dyspnea caused by laryngeal dyspnea, respiratory dysfunction or retention of secretion of the lower respiratory tract, can keep the respiratory tract of a patient smooth, improve dyspnea caused by various reasons, correct the anoxic state of the patient and the like.
Currently, tracheal intubation is widely used clinically. The following defects exist in the clinical application process, namely 1, the current plugging saccule is cylindrical. After filling, the balloon can press the inner wall of the trachea of the longer section, so that the mucous membrane of the longer section of the inner wall of the trachea is pressed. In addition, the balloon with the shape has more folds in the contracted state, which affects the insertion of the trachea cannula. 2, research shows that when the pressure between the cuff and the tracheal wall exceeds the perfusion pressure (20-30 mmHg) of the tracheal mucosa capillary vessel, ischemic injury occurs to the tracheal mucosa. Prolonged over-inflation of the cuff can also cause oedema necrosis, ulceration and tracheal cartilage necrosis of the tracheal mucosa pressed by the cuff, fibrous tissue proliferation and/or tracheal collapse, which in turn creates a tracheal stenosis. The harm of the airway stenosis is large and the treatment difficulty is high. The detection method of the cuff filling pressure comprises three methods (1) a finger touch method, namely, the finger touch indication air bag is similar to the nose tip in elasticity to indirectly judge the cuff filling pressure, and the method is most commonly adopted in the emergency tracheal intubation. This approach is highly subjective and often results in over inflation of the cuff. (2) The cuff pressure gauge detects the filling pressure of the cuff reliably and accurately. However, manual measurement does not effectively control the cuff pressure and can cause the cuff to leak when connecting and disconnecting the pressure tube. The cuff inflation pressure is thus often set to be somewhat higher than the target value using a cuff pressure gauge. (3) Automatic inflator continuous pressure measurement or continuous cuff pressure monitoring systems have great advantages in continuously monitoring cuff pressure and stabilizing cuff pressure, but are expensive and difficult to popularize in clinical practice. And 3, the section from the subglottal part to the upper part of the tracheal cannula balloon generates more secretion, but is not easy to suck out to form a potential infection source.
