Embodiment 1

[0028] see Figure 1-2 , the end-tidal carbon dioxide guiding endotracheal intubation device of the present invention includes: a tube body 1, an axial fiber 6 on the inner wall of the tube body 1, and a regulator 7 at the end of the tube body 1, and one end of the tube body 1 is a terminal interface 2 for Connect the end-tidal carbon dioxide sensor; the other end is the front insertion port 3 for inserting into the trachea. The axial fibers 6 include two axial fiber bundles arranged axially along the inner wall of the pipe body 1 and arranged symmetrically with respect to the axis of the pipe body 1. Displacement, and one end is fixed on the regulator 7, and the other end is fixed on the front end insertion port 3; the front end insertion port 3 of the pipe body also has an annular elastic member 5 arranged along the inner wall of the pipe body 1. The inner wall of the pipe body 1 has a ring-shaped inner wall protrusion 4 at the distal end of the front end insertion port 3 o...

Embodiment 2

[0032] On the basis of the above-mentioned embodiment 1, there is a first scale (not shown) on the outer wall of the pipe main body 1 at the adjustment wrench 11 , and a second scale 8 is provided on the outer surface of the pipe main body 1 in the axial direction.

Embodiment 3

[0034] On the basis of the above-mentioned embodiment 2, the outer diameter of the pipe body 1 at the annular elastic part 5 is 7 / 12 of the outer diameter at other parts of the pipe body.

Abstract

The invention relates to an end-tidal carbon dioxide trachea guide insertion device, which comprises a tube main body, an axial fiber on the inner wall of the tube main body, and an adjuster at the tail end of the tube main body, wherein a tail end interface is arranged in one end of the tube main body and is used for connecting an end-tidal carbon dioxide inductor and a front-end insertion opening is formed in the other end of the tube main body and is used for inserting into a trachea; and once end-tidal carbon dioxide is induced, the waveform of the end-tidal carbon dioxide can be displayed on a monitor. The end-tidal carbon dioxide trachea guide insertion device is not affected by the mouth opening of a patient and the head and neck activity, is not affected by the obesity level of the patient, is not affected by secretions and blood in an airway of the patient; and the waveform of the end-tidal carbon dioxide can be displayed on the monitor and a tracheal catheter can be guided to be implanted as long as the device reaches an aditus glottidis and enters a trachea.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an end-tidal carbon dioxide-guided endotracheal intubation device. Background technique [0002] The management of difficult airway is still one of the most serious challenges anesthesiologists face, and it is closely related to anesthesia safety and anesthesia quality. Improper airway management and failure to maintain normal ventilation of the patient will directly affect the life of the patient. Therefore, how to deal with difficult airway and how to control the ventilation of patients with difficult airway are hot issues that anesthesiologists pay attention to. [0003] With the introduction of a large number of new airway devices, there are more and more methods of airway management, but each method and each device has its advantages and disadvantages. At present, the equipment used for difficult airway intubation is mainly fiberoptic bronchoscope (referred to as f...
