Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a kind of oropharyngeal airway device based on dental pad. BACKGROUND

[0002] Painless gastroenterological endoscopy as an important diagnostic method plays an indispensable role in clinical diagnosis and treatment. However, due to the need to give patients sedatives during the examination process, it leads to tongue root falling backward, and further causes upper airway obstruction. At present, the solution to upper airway obstruction caused by tongue falling backward in painless gastroenterological endoscopy is mainly to place nasopharyngeal airway, and the placement of nasopharyngeal airway needs to be placed through the nasal cavity, which can cause damage to the nasal mucosa and bleeding in many patients during the placement process. Therefore, the improved ordinary oropharyngeal airway and gastroenterological endoscopy dental pad can solve the problem of keeping the airway unobstructed and not affecting the placement of gastroscope.

[0003] Although the oropharyngeal airway device based on dental pad plays an important role in painless gastroenterological endoscopy, there are still some technical problems. First, due to the complex structure or high sensitivity of the throat of some patients, the insertion process of oropharyngeal airway may be difficult, and even cause discomfort or injury to the patient; during the examination process, how to ensure the stability of the fixation of oropharyngeal airway is a key problem. If it is not fixed firmly, it may cause oropharyngeal airway to fall off or shift, affecting the examination effect. SUMMARY

[0004] In view of the above shortcomings in the prior art, the oropharyngeal airway device based on dental pad provided by the utility model solves the problems of difficult insertion, unstable fixation and low oxygen supply efficiency of oropharyngeal airway in the prior art.

[0005] In order to achieve the above-mentioned utility model purposes, the utility model adopts the technical scheme: an oropharyngeal airway device based on dental pad, comprising a dental pad, a through hole is provided on the dental pad, an oropharyngeal airway is provided in the through hole, the oropharyngeal airway comprises a duck tongue opening and a pipeline connected with the duck tongue opening, an air pipe is provided on the inner wall of the pipeline, and a biting part is provided on the outer wall of the through hole.

[0006] The device is combined with a dental pad design, the biting part is used for stabilizing the position of the dental pad, displacement or falling of the oropharyngeal airway caused by movement of the head of the patient or muscle tension is effectively prevented, and therefore, stability and safety of airway management are greatly improved. Meanwhile, the oropharyngeal airway arranged in the through hole is directly aligned with the throat, airway bending is reduced, airway resistance is reduced, and a smooth breathing passage is ensured. The duck-billed mouth design enlarges the entrance, and the gastroscope is conveniently inserted into the pipeline from the duck-billed mouth and then into the stomach from the pipeline. Because the oropharyngeal airway is arranged in the through hole, the gastroscope can enter the inside of the body of the patient from the through hole in the painless gastroscopy process.

[0007] Further, the oropharyngeal airway device is provided with a silica gel layer on the surface of the oropharyngeal airway.

[0008] The silica gel layer arranged on the surface of the oropharyngeal airway can significantly reduce the friction coefficient between the device and sensitive tissues such as the oral mucosa and the throat of the patient, and reduce discomfort caused by long-term contact or slight movement.

[0009] Further, the oropharyngeal airway device is provided with a flexible protrusion on the biting part.

[0010] The flexible protrusion is arranged to disperse the biting pressure, reduce the compression on the soft tissue of the oral cavity, more closely fit the natural form of the occlusal surface of the teeth of the patient, and increase the fixing force of the device in the oral cavity. The physical locking mechanism helps to prevent displacement or falling of the oropharyngeal airway when the patient breathes, swallows or slightly moves the head, thereby ensuring continuity and stability of the airway.

[0011] The overall design of the oropharyngeal airway device fully considers the physiological characteristics and clinical needs of the patient, aims to reduce discomfort, improve airway efficiency and other ways to promote the rehabilitation process of the patient. At the same time, stable device fixation and soft material selection also help to prevent complications that may be caused by long-term use of the oropharyngeal airway, such as pharyngeal edema and ulceration.

[0015] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0016] like Figs. 1-2 As shown, this embodiment provides an oropharyngeal airway device based on a dental pad, which effectively ensures airway patency and facilitates smooth breathing for the patient. The device includes a dental pad 1, which is placed inside the patient's mouth to support the airway. A through-hole 2 is provided on the dental pad 1, and an oropharyngeal airway 3 is disposed within the through-hole 2. The oropharyngeal airway 3 includes a duckbill-shaped opening 4 and a tube 5 connected to the duckbill-shaped opening 4. The design of the duckbill-shaped opening 4 enlarges the entrance, conforming to the human oral cavity while facilitating the insertion of a gastroscopy through the duckbill-shaped opening 4 into the tube 5, and then into the stomach through the tube 5. The design of this oropharyngeal airway 3 conforms to the anatomical structure of the human oropharynx, ensuring smooth airflow. A ventilation tube 6 is disposed on the inner wall of the oropharyngeal airway 3 for introducing gas, ensuring the patency of the oropharyngeal airway 3.

[0017] The outer wall of the through hole 2 is provided with a biting part 7, which is in close contact with the teeth in the patient's mouth. The airway device is fixed by the biting of the teeth to prevent it from shifting.

[0018] A silicone layer is provided on the surface of the oropharyngeal airway 3. This silicone layer can increase the comfort of the airway and reduce friction damage to the patient's oral mucosa; the bite part 7 is provided with a flexible protrusion, which can better adapt to the shape of the patient's teeth and improve the stability of the airway device.

[0019] The oropharyngeal airway device based on a bite block provided in this embodiment can ensure normal breathing for patients, greatly improve patient comfort, and is suitable for patients who need airway support, such as patients undergoing painless gastroscopy and colonoscopy.
