Problems solved by technology

In addition, for some bronchoscopes with small tube diameters, although they are inserted into the standpipe 110 and the endotracheal tube 130 from the bronchoscope insertion hole 141, due to the relatively large gap between the bronchoscope insertion hole 141 and the bronchoscope, there will be Air leakage affects examination and operation

Embodiment Construction

[0017] Existing cannulas for use with bronchoscopes can be found at figure 1 , is a three-way structure 100, with a vertical tube 110 and a horizontal tube 120, the lower end of the vertical tube 110 is connected to the endotracheal tube 130, the endotracheal tube 130 is inserted into the patient's trachea, and the horizontal tube 120 can be connected to oxygen or anesthesia through the installation interface 121 gas. A sealing body 140 is provided at the upper end of the standpipe 110 , and a bronchoscope insertion hole 141 is opened on the sealing body 140 , and a sealing cover 142 is covered on the fiberglass insertion hole 141 .

[0018] During inspection or operation, the endotracheal tube 130 is inserted into the patient's trachea, then the sealing cover 142 is opened, and the bronchoscope is inserted into the standpipe 110 and the endotracheal tube 130 through the endoscopic insertion hole 141 to detect or operate on the patient.

[0019] Usually in the inspection or o...

Abstract

The invention discloses an intubation tube structure applicable to bronchofiberscopes of different specifications. The intubation tube structure is a three-way tube fitting and is provided with a vertical tube and a transverse tube, wherein a sealing body is arranged at the upper end of the vertical tube, a bronchofiberscope insertion hole is formed in the sealing body, and a sealing cover coversthe bronchofiberscope insertion hole. The intubation tube structure is characterized in that an inflatable and deflatable air bag is arranged on the inner wall of the vertical tube, is arranged on theupper section of the vertical tube and is positioned between the sealing body and the transverse tube; and the inflatable and deflatable air bag can expand towards the diameter direction of the bronchofiberscope during inflation to wrap the outer diameter of the bronchofiberscope. By arranging the inflatable and deflatable air bag on the vertical tube, instruments with different pipeline thicknesses can be adapted, and meanwhile, the situation that the sealing performance is reduced, and inspection and operation are affected is avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an intubation tube structure that can be used for fiberoptic bronchoscopes of different specifications. Background technique [0002] Fiber bronchoscope is the abbreviation of fiber bronchoscope. It is an instrument used to diagnose bronchial diseases by using a light guide composed of tens of thousands of highly transparent glass or acrylic resin drawn into very thin fibers. Because of its small lumen, softness and bendability, strong light guiding ability, high transparency, and clear vision, it can easily enter the bronchi and the bronchial segments at all levels below through the oral cavity and nasal cavity, allowing doctors to easily observe the trachea, left and right For the conditions of the bronchial ports and mucous membrane, the small brush attached to the instrument can also be used to brush the lesioned mucous membrane tissue at the mucous membrane for pathologica...
