Abstract

The present invention provides a method and a device for positioning a canal in a human trachea. The method comprises inserting a probe having a signal generation source into a canal; attaching a position sensor at the outside of the Adam's apple of a patient; inserting the canal equipped with the probe into the throat of a patient; detecting the signal, emitted by the signal generation source installed in the probe, by the sensor when the canal is accurately inserted into the passage of the trachea; displaying the light and humming sound by a control box equipped with a circuit control system to indicate that the canal is correctly positioned in the opening of the trachea; withdrawing the probe after the canal has been correctly positioned and connecting the section of the canal outside the human body to a breathing aid or manual squeezing-type air-supply ball.

Description of the Invention (1) The present invention relates to a method and device for intubation positioning of the human trachea, particularly a method that can easily determine the endotracheal insertion. Guangu · A positioning method that is positioned on the human trachea instead of being placed in the esophagus and is applied to the method of the present invention, which is not only convenient to carry out and used in first aid and easy to place in a medical site, and its equipment cost is low, but Moreover, it has a practical value for medical safety. It is a new invention that breaks through the intubation operation of human trachea. When performing a surgical operation in the operating room, the patient must be subjected to general anesthesia, and to perform general anesthesia, an endotracheal intubation must be performed. The endotracheal tube is positioned in the patient's trachea and the other end The connected breathing aid provides oxygen necessary for patients to maintain their lives. Because the human tracheal opening is close to the esophagus opening, it is not easy to observe with poor eyesight. When the operator inserts the intubation tube into the esophagus by mistake, if it is not found in time, it will not only lead to hypoxia, cardiac arrest, Nervous system damage, and even death of patients, has led to many medical disputes. In view of the serious life-threatening problems and posterior problems caused by the intubation of the intubation tube in the esophagus, a carbon dioxide analyzer is installed in the general operating room. The carbon dioxide analyzer is used to monitor the carbon dioxide concentration exhaled by the patient's lungs. As a judgment to determine whether the intubation tube is correctly inserted into the trachea, the installation cost of this carbon dioxide analyzer is quite high. Except for the operating room, it is not widely used in general emergency rooms, intensive care units, and out-of-care first aid. In general emergency rooms, intensive wards, and out-of-care facilities, the methods used to help patients breathe are to first insert the intubation tube into the patient's trachea, and then use a manual squeeze-type balloon to connect the intubation tube and continue to press. Squeeze the balloon to provide the patient's breath. In the state where the patient can no longer breathe on his own and the situation is urgent, if the operator is slightly uncomfortable, it may cause regret that is beyond repair. What's more, when the rescued patient is not anesthetized, when the intubation tube is inserted into the human throat, the larynx nervous system will close the opening of the trachea due to contact with the object.
