[0002] An oropharyngeal airway is a simple airway assist device used to keep the upper airway open for patients. It is mainly used for patients who are under general anesthesia, unconscious, or comatose, and whose spontaneous breathing is present but whose swallowing reflex is weakened or absent. It is inserted into the patient's mouth to ensure that air can enter the airway smoothly and maintain effective ventilation.

[0003] Traditional oropharyngeal airways have significant limitations: their fixed-angle design makes it difficult to adapt to the curvature of different patients' mouths and airways; when inserting endoscopic instruments, the tube may bend and obstruct the operation, causing discomfort due to its inability to fit the airway; moreover, they have limited functionality, only maintaining airway patency, lacking precise oxygen supply devices for patients with difficult airways, and are unable to monitor ventilation effectiveness in real time, which can easily lead to problems such as insufficient oxygen supply and ineffective ventilation. This increases the risk of hypoxia and asphyxia in obese patients and patients with short necks during invasive examinations or intubation, and makes it difficult to meet the needs of complex airway management. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a dual-interface monitoring oropharyngeal jet airway, which solves the problems of poor adaptability of existing oropharyngeal airway angles, insufficient oxygen supply to patients with difficult airways and lack of real-time ventilation monitoring, resulting in obstructed operation and high risk of hypoxia and suffocation.

[0005] The present invention also provides a dual-interface monitoring oropharyngeal jet ventilation system, comprising: an oropharyngeal ventilation tube, a bite pad fixedly connected to the outer wall of the oropharyngeal ventilation tube, a flange fixedly connected to the outer side of the bite pad, an oxygen jet tube connected to the side surface of the oropharyngeal ventilation tube, an end-tidal carbon dioxide monitoring tube connected to the side surface of the oropharyngeal ventilation tube, and an internal interlayer provided in the oropharyngeal ventilation tube, wherein an adjustable angle skeleton is provided inside the interlayer.

[0006] According to the dual-interface monitoring oropharyngeal jet airway of the present invention, the adjustable angle frame includes: multiple connecting frames and multiple supports, wherein the multiple connecting frames are hinged to each other, and every two supports are fixedly connected between two connecting frames.

[0008] According to the dual-interface monitoring oropharyngeal jet airway of the present invention, a through channel is provided on the dental pad, the pull rope slides inside the through channel, and the pull rope passes through the through channel to the other side of the flange.

[0009] According to the dual-interface monitoring oropharyngeal jet airway of the present invention, a clamping and fixing assembly is provided on the flange, and the clamping and fixing assembly is movably connected to the pull rope.

[0010] According to the dual-interface monitoring oropharyngeal jet airway of the present invention, the clamping and fixing assembly includes: a pad and a pressure plate, the pad being fixedly connected to the front surface of the flange, the pressure plate being movably connected to the upper surface of the pad, and the pull rope being located between the pressure plate and the pad.

The oxygen jet cannula can directly and precisely deliver oxygen into the airway, solving the problem of insufficient oxygen delivery caused by the special airway structure of obese patients, short-necked patients, or those with difficult airways or oxygen delivery difficulties. It maintains stable blood oxygen saturation and avoids the risk of hypoxia.

[0016] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0017] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 This invention provides a dual-interface monitoring oropharyngeal jet airway, comprising: an oropharyngeal airway 1. Considering the lack of bite-lock protection and fixation structure in traditional airways, a bite pad 4 is fixedly connected to the outer wall of the oropharyngeal airway 1. A flange 5 is fixedly connected to the outer side of the bite pad 4. The bite pad 4 prevents the patient from biting off the lumen, and the flange 5 abuts against the lips to achieve a stable airway. Reference Figure 1 , Figure 5 Considering the inconvenience of oxygen delivery and ventilation monitoring for patients with difficult airways, the side surface of the oropharyngeal airway 1 is connected to an oxygen jet tube 2 and an end-tidal carbon dioxide monitoring tube 3. The oxygen jet tube 2 provides precise oxygen delivery, and the end-tidal carbon dioxide monitoring tube 3 provides real-time feedback on the ventilation status, achieving a synergistic effect of oxygen delivery and monitoring. Reference Figure 3 , Figure 4 The oropharyngeal airway 1 has an internal interlayer 7. Considering the poor adaptability of the fixed angle of the airway, the interlayer 7 is equipped with an adjustable angle frame. The adjustable angle frame includes multiple connecting frames 9 and multiple supports 8. The multiple connecting frames 9 are hinged to each other, and every two supports 8 are fixedly connected between two connecting frames 9. The connecting frames 9 are hinged and flexible. The supports 8 enhance the support of the oropharyngeal airway 1, achieving the basic effect of adjustable angle. Reference Figure 4Considering the issue of adjusting the frame angle, the adjustable frame also includes two pull ropes 10. Both pull ropes 10 are threaded inside the multiple connecting frames 9 and fixedly connected to the end connecting frame 9. The two pull ropes 10 are located on the upper and lower sides of the connecting frame 9, respectively. Pulling the pull ropes 10 drives the end connecting frame 9, causing the frame to bend at the hinge of the multiple connecting frames 9, thus achieving the effect of precise angle adjustment.

[0018] In summary, the improvement of this embodiment lies in: The adjustable frame, together with the upper and lower pull ropes 10, can bend the oropharyngeal airway 1 up and down by pulling different pull ropes 10. It can be straightened for easy operation when inserting gastroscopy instruments, and can be restored to the angle that fits the curvature of the patient's oral cavity during the operation, thus solving the problem of poor adaptability of the fixed angle of the traditional airway. The oxygen jet tube 2 can directly and precisely deliver oxygen into the airway, solving the problem of insufficient oxygen delivery caused by the special airway structure of obese patients, short-necked patients, or patients with difficult airways or oxygen delivery difficulties. It maintains stable blood oxygen saturation and avoids the risk of hypoxia. The end-tidal carbon dioxide monitoring tube 3 can monitor the patient's end-tidal carbon dioxide concentration in real time and provide timely feedback on the effectiveness of ventilation. The two work together to ensure continuous oxygen supply and achieve dynamic monitoring of ventilation status during invasive examinations or intubation procedures, which greatly reduces the risk of complications such as hypoxia and asphyxia in patients with difficult airways and improves the safety and reliability of examination and intubation procedures.

[0019] Based on the above, other structures also need to be disclosed in detail, such as: Reference Figure 3 Considering the issue of the cord 10 routing, a through channel 6 is provided on the dental pad 4. The cord 10 slides inside the through channel 6 and passes through the through channel 6 to the other side of the flange 5. The cord 10 slides along the through channel 6 to avoid tangling, thus achieving the effect of orderly guiding the cord 10.

[0020] Reference Figure 2 Considering the issue of fixing the angle after adjustment, a clamping and fixing component is provided on the flange 5. The clamping and fixing component is movably connected to the pull rope 10. The component clamps the pull rope 10 to fix the position, thereby achieving the effect of angle locking.

[0021] Reference Figure 2 The clamping and fixing assembly includes: a pad 13 and a pressure plate 12. The pad 13 is fixedly connected to the front surface of the flange 5, and the pressure plate 12 is movably connected to the upper surface of the pad 13. The pull rope 10 is located between the pressure plate 12 and the pad 13. A stud 14 is fixedly connected to the upper surface of the pad 13. The stud 14 is threaded through and connected to the inside of the pressure plate 12. The pressure plate 12 presses the pad 13 with the stud 14, clamps the pull rope 10 to prevent loosening, and achieves a stable fixing effect.

[0022] Reference Figure 2 Both the pad 13 and the pressure plate 12 are provided with grooves 11. The pull rope 10 is movably connected to the grooves 11. After clamping, the pull rope 10 is embedded in the grooves 11 to limit displacement and enhance the effect of fixing the rope.

[0023] Working principle: When using this dual-interface monitoring oropharyngeal jet airway, first insert the oropharyngeal airway 1 into the patient's mouth, prevent the patient from biting down on the lumen through the bite pad 4, and fix the overall position by the wing 5 against the lips. According to the patient's oral curvature or operational needs, pull the up and down pull ropes 10 on the other side of the flange 5. The pull ropes 10 slide along the through channel 6 of the dental pad 4, causing the connecting frame 9 of the adjustable angle skeleton in the interlayer 7 to bend around the hinge. The support 8 enhances the support, causing the oropharyngeal airway 1 to bend up and down accordingly. After adjusting to the appropriate angle, tighten the stud 14 of the clamping and fixing component, so that the pressure plate 12 and the pad 13 clamp the pull rope 10 through the groove 11 and lock the current angle; If it is necessary to insert gastroscopy instruments, pull the pull rope 10 to straighten the oropharyngeal airway 1, and then adjust it back to the appropriate angle after the operation is completed; Meanwhile, the oxygen injection tube 2 connects to the oxygen source to accurately supply oxygen into the airway, and the end-tidal carbon dioxide monitoring tube 3 monitors and provides feedback on the patient's ventilation status in real time. The two work together to ensure the safety of oxygen supply and ventilation. Throughout the process, the groove 11 prevents the pull rope 10 from slipping, ensuring that the equipment functions stably during invasive examinations or intubation procedures. This not only meets the angle adjustment requirements but also achieves synergy between oxygen supply and monitoring, improving the operational safety for patients with difficult airways.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
