Description

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an ultrasonic positioning tracheal catheter.

Background

The tracheal intubation is widely applied clinically, particularly applied to the airway management of general anesthesia operation, intensive care and emergency patients, the traditional tracheal catheter positioning is mainly determined by virtue of an empirical formula, positioning errors are easily caused by individual differences of patients, anatomic structure changes and other factors, the depth of the tracheal catheter cannot be accurately estimated, airway mucosa can be damaged due to over-deep tracheal intubation, arrhythmia, choking and airway spasm are caused by the stimulation of the carina, hypoxia, pneumothorax, pulmonary atelectasis and the like are caused by the placement of the front end of the catheter into a unilateral main bronchus, and the sliding off, glottic injury and failure of the catheter are easily caused by the over-shallow tracheal intubation. It is therefore important to accurately assess the depth of endotracheal tube insertion.

The defects of the ultrasonic positioning tracheal catheter in the prior art are as follows:

1. patent document CN209662374U discloses an antimicrobial lubricated tracheal catheter for ultrasonic positioning, comprising an tracheal catheter balloon on the front of the tracheal catheter, the tracheal catheter balloon is connected with an inflatable tube, a lower display ring is arranged on the outer surface of the front end of the tracheal catheter, an upper display ring is arranged on the wall of the tracheal catheter above the tracheal catheter balloon, an antimicrobial layer is sprayed on the inner surface of the wall of the tracheal catheter on the lower display ring, the tracheal catheter part in the balloon, the upper display ring and the front end of the tracheal catheter, and a lubricant layer is sprayed on the outer surfaces of the lower display ring, the tracheal catheter balloon, the upper display ring and the tracheal catheter on the front end of the tracheal catheter. The utility model improves the ultrasonic development capability of the front end of the tracheal catheter, and is favorable for the real-time monitoring of the position and depth of the tracheal catheter developed by the front end in the intubation process. The device can save the time of trachea cannula, reduce the operation procedure in the trachea cannula process, reduce the mucous membrane damage' caused by the friction resistance of the tracheal catheter and the tracheal mucous membrane wall, but the device can not effectively achieve the display effect through direct inflation and liquid when in use, for example, the resistance of the liquid is increased when the tracheal catheter cuff is injected or extracted, and the pressure is higher than that of the injected air, so that the potential risks of overlarge pressure rupture of the cuff, damage to the tracheal wall and glottic structure are present, and meanwhile, the device is influenced by the endocrine of the trachea, so that the ultrasonic imaging positioning of the method is ambiguous.
