Description

Bronchofiberscope guide trachea cannula auxiliary part

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to bronchofiberscope guide trachea cannula auxiliary member.

Background

Tracheal intubation is one of the most common procedures for clinical anesthesia and is also the most effective means for controlling the airway. Endotracheal intubation is currently commonly accomplished using laryngoscope exposure, but often requires special preparation for potentially difficult airways, such as restricted ostia, restricted head and neck mobility, neck occupancy, etc. Bronchofiberscope-guided surface anesthesia and endotracheal intubation are among the preferred methods for difficult airway conscious intubation. Generally, after the surface of an effective intubation path is anesthetized, an endotracheal tube is sleeved on a bronchofiberscope, the trachea is inserted by utilizing the flexibility and the visibility of the bronchofiberscope, and then the endotracheal tube is placed into the trachea along the bronchofiberscope to complete the sober endotracheal intubation.

This method allows for tracheal intubation to be accomplished with the patient awake, due to adequate surface anesthesia and bronchofiberscope guidance, thereby eliminating the need for laryngoscope exposure. However, the existing surface anesthesia has poor effect, and the anesthetic is not uniformly distributed in the airway of a patient. Besides, the conscious intubation can cause injury to the throat and even cause intubation failure, one reason is that the intubation is difficult to insert due to the relative stenosis and even spasm closing of the glottis when the catheter passes through the glottis in the process of inserting the catheter and the influence of the conscious state and the surface anesthesia effect of the patient; the bronchofiberscope is thin (about 3mm) in pipe diameter, and the internal diameter of a common adult tracheal catheter is 6.5-8.0 mm, and the trachea catheter is difficult to pass through a relatively narrow glottis and is easy to cause injury to the throat due to the fact that the posture and the anatomical abnormality of a patient with a difficult airway are added.

Moreover, clinically difficult airway cases are rare, and most clinical anesthesiologists do not have the rich experience of conscious intubation. Therefore, a convenient and practical's device can effectively assist the tracheal catheter who accomplishes under the bronchofiberscope guide to easily put into and not only can improve clear-headed intubate success rate, also can reduce the wound to patient's throat simultaneously, improves anesthesia control air flue level, saves patient's life even.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned not enough, the utility model provides a bronchofiberscope guide trachea cannula auxiliary member, the success rate that this auxiliary member can effectively solve the trachea cannula in-process and exist is low, easily causes the problem of patient's back air flue wound.

In order to achieve the above object, the present invention provides a technical solution for solving the technical problem:
