Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an oropharyngeal airway for assisting in bronchoscope intubation. Background Technology

[0002] Endotracheal intubation is an important technique for clinical anesthesia, establishing airways, emergency resuscitation, and rescuing critically ill patients. Endotracheal intubation general anesthesia is the most common anesthesia method in clinical practice. Fiberoptic bronchoscopy (FOB) guided endotracheal intubation is the most effective method for solving intubation problems. It is the gold standard for endotracheal intubation in patients with anticipated difficult airways and is also one of the important options for adults with unexpected difficult airways.

[0003] Existing fiberoptic bronchoscope tubes are too soft and cannot be easily inserted into the oral cavity. Therefore, we propose the use of oropharyngeal airway-assisted fiberoptic bronchoscope tube insertion. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an oropharyngeal airway for assisting in bronchoscope intubation, overcoming the deficiencies of existing technologies and effectively solving the problem that the bronchoscope cannula is too soft to be easily inserted into the oral cavity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An oropharyngeal airway for assisting in bronchoscopic intubation includes an oropharyngeal airway body, the oropharyngeal airway body including a tongue depressor and an insertion part, wherein the insertion part is placed on the inner wall of the tongue depressor, the tongue depressor including a flange, a pharyngeal bend tube fixedly connected to the outer wall of the bottom of the flange, and a curved groove formed on the inner ring of the pharyngeal bend tube.

[0006] Preferably, the insertion part includes a cannula seat disposed on the inner wall of the top of the tongue depressor, an inner cannula fixedly connected to the outer wall of the bottom of the cannula seat, a rubber seal tightly attached to the inner wall of the inner cannula, and inclined openings disposed at both ends of the outer wall of the bottom of the cannula seat.

[0007] Preferably, a fiberoptic bronchoscope cannula is disposed inside the main body of the oropharyngeal airway.

[0008] Preferably, the tongue depressor has an air vent inside, and the bronchoscope cannula is inserted through the air vent.

[0009] Preferably, a sealing groove is provided on one side of the outer wall of the insertion part, and the rubber seal is tightly attached to the inner wall of the sealing groove.

[0010] Preferably, the outer walls of both sides of the rubber seal are provided with positioning strips, and the inner walls of both sides of the sealing groove are provided with positioning grooves, with the positioning strips slidably connected to the inner walls of the positioning grooves.

[0011] Preferably, anti-slip strips are provided on the outer wall of the inclined surface of the ramp.

[0012] The beneficial effects of this utility model are as follows: 1. The oropharyngeal airway for assisting bronchoscope intubation in this design, through the cooperation of the wing and pharyngeal bend tube, as well as the intubation seat, internal tube, rubber seal and bevel, not only facilitates the assembly of the tongue depressor and the intubation section, but also effectively assists in the insertion of the bronchoscope tube into the patient's trachea. 2. The oropharyngeal airway of the auxiliary fiberoptic bronchoscope in this design features a curved groove on the tongue depressor and a rubber seal on the insertion part. After the fiberoptic bronchoscope cannula is in place, the rubber seal can be removed, creating a notch in the entire oropharyngeal airway body. This allows for separation of the oropharyngeal airway body from the fiberoptic bronchoscope cannula, facilitating the removal of the oropharyngeal airway body. The operation is simple and has excellent performance. Attached Figure Description
