Description

Technical Field

[0001] The utility model relates to the technical field of upper respiratory tract management in the medical field, in particular to a nasopharyngeal airway capable of preventing upper respiratory tract obstruction, collecting exhaled gas samples, and clearing oral secretions and vomitus. Background Art

[0002] The management of the upper respiratory tract includes many items such as the patency of the upper respiratory tract, the collection of exhaled air, and the cleaning of oral secretions, vomitus, and coughed-up materials.

[0003] The cross-sectional shape of the nasopharyngeal airway currently popular on the market is circular, which does not conform to the physiological structure of the human nasal concha and can easily cause discomfort to patients or even a deviated nasal septum. Moreover, the design of the nasopharyngeal airway with carbon dioxide collection used clinically is unreasonable. The carbon dioxide gas exhaled by patients who inhale oxygen through the nasopharyngeal airway is washed away by the oxygen, and almost no carbon dioxide content can be collected, making it impossible to effectively observe and measure the exhaled carbon dioxide.

[0017] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0018] Example 1

[0019] A flat nasopharyngeal airway integrating suction, oxygen supply and carbon dioxide collection. The flat cylindrical nasopharyngeal airway is a flat cylindrical nasopharyngeal airway integrating suction, oxygen supply and carbon dioxide collection.

[0020] It comprises a nasopharyngeal airway main body 1, which is a hollow flat cylinder and is made of medical latex material.

[0021] The head bevel openings of the nasopharyngeal airway body 1 include an oxygen supply tube side hole 101, a carbon dioxide collection tube side hole 102, and a suction hole 103. The three groups of side holes are distributed at different positions of the head end of the nasopharyngeal airway body 1, and each group of side holes has its own function;

[0022] The tail end of the nasopharyngeal airway body 1 includes a main breathing hole 104 and three sets of tail tubes, which are an oxygen supply tube 2, a carbon dioxide collection tube 3 and a suction tube 4, wherein the oxygen supply tube 2 is connected to the oxygen supply tube side hole 101, the carbon dioxide collection tube 3 is connected to the carbon dioxide collection tube side hole 102, and the suction tube 4 is connected to the suction hole 103.

[0023] The side holes of the head section of the nasopharyngeal airway body 1 have a group of suction holes 103 on one side of the nasopharyngeal airway body 1, and the suction holes 103 are gathered into a pipeline connected to the suction tube 4 at the tail end of the nasopharyngeal airway body 1. In clinical use, the suction holes 103 face below the nasal concha, and after the suction holes 103 are placed, they are close to the posterior pharyngeal wall, and oral secretions and vomitus are sucked through the suction tube 4.

[0024] A group of side holes opposite to the suction hole are carbon dioxide collection tube side holes 102, which are gathered into a pipeline connected to the carbon dioxide collection tube 3 at the tail end of the nasopharyngeal airway body 1 for carbon dioxide gas collection and analysis.

[0025] The upper side hole of the carbon dioxide collection tube side hole 102 is the oxygen supply tube side hole 101 , and the oxygen supply tube side holes 101 are gathered into a pipeline connected to the oxygen supply tube 2 at the tail end of the nasopharyngeal airway body 1 .

[0026] The flat airway design of the nasopharyngeal airway body 1 conforms to the physiological anatomy of the human body, is easy to insert and comfortable for the patient. The design of multiple sets of oxygen supply tube side holes 101, carbon dioxide collection tube side holes 102, and suction holes 103 ensures that oxygen is supplied and the oral cavity is cleaned at the same time. The carbon dioxide collection tube side hole 102 is closer to the patient's glottis, and when the patient exhales, the oxygen sprayed from the oxygen supply side hole can be exhaled, which effectively measures the patient's exhaled carbon dioxide more accurately.
