Background

Replacement tracheal intubation is performed through the mouth or nose and into the trachea of a living subject through the throat, glottis to form a airway. The replaceable tracheal tube is usually placed in the trachea of a human body, and a new replaceable tracheal tube needs to be replaced in the trachea of the human body about the last one to two weeks so as to prevent bacterial infection, prevent the inner wall of the trachea of the human body from being adhered to the replaceable tracheal tube, or immediately replace the replaceable tracheal tube when an air sac of the replaceable tracheal tube is broken. At present, when a new replaceable cuff is to be replaced, the old replaceable cuff is removed from the oral cavity to replace the new replaceable cuff. When replacing the new replaceable tracheal tube sleeve, the luminous flexible tube or the laryngoscope is used to irradiate the trachea of the human body through the oral cavity in advance, and then the new replaceable tracheal tube sleeve enters from the oral cavity and is partially inserted into the trachea of the human body.

However, the lighting flexible tube or the laryngoscope can not clearly observe the position of the trachea of the human body by irradiating the trachea of the human body through the oral cavity, and the new replaceable tracheal tube can not be positioned in the trachea of the human body when the new replaceable tracheal tube is arranged in the trachea of the human body, so that the inconvenience of replacing the new replaceable tracheal tube by an operator is caused. Therefore, when the replaceable tracheal tube sleeve is replaced, the luminous flexible tube or the laryngoscope is required to detect that the new replaceable tracheal tube sleeve needs to be aligned to the exact position of the trachea of the human body, and then the new replaceable tracheal tube sleeve is placed in the trachea of the human body for repeated operation, which further causes discomfort and inconvenience for the patient.

In view of the above, the present invention provides an endoscope structure with replaceable tracheal tube, so as to overcome the shortcomings of the prior art, based on the accumulated experience of the inventor in the industry for many years.
