AI Technical Summary
The existing oropharyngeal airways are easily blocked by sputum in the throat due to the oval hollow plastic tube structure, resulting in the loss of ventilation, and there is a greater risk of use.
An anti-blocking oropharyngeal ventilation channel is designed, including two pallets for supporting the oral cavity and throat. A connecting plate is arranged between the pallets that are vertically connected to it, and the two sides of the connecting plate and the pallet are between the pallets. Create an open groove-like channel to avoid blockage of sputum.
An open groove-like channel is formed through the connection between the pallet and the connecting plate, which effectively prevents the oropharyngeal ventilation duct from being blocked by sputum, ensures the sustainability of ventilation and reduces the risk of use.

Abstract
Description
Technical Field
[0001] The present application relates to the technical field of oropharyngeal airways, and in particular to an anti-blocking oropharyngeal airway. Background Art
[0002] In the prior art, the oropharyngeal airway is usually made of rubber or plastic, or metal or other elastic materials. The commonly used oropharyngeal airway in clinical practice is an elliptical hollow plastic tube with an "S" shape, including a wing edge, a tooth pad part and a pharyngeal curved part. It is a non-tracheal tube non-invasive ventilation tube that can prevent the tongue from falling back, quickly open the airway, and establish a temporary artificial airway. However, this oropharyngeal airway is often blocked by phlegm in the throat during use, thereby losing its ventilation function and posing a greater risk of use. Utility Model Content
[0003] The problem to be solved by the present application is that the existing oropharyngeal airway is an elliptical hollow plastic tube structure, which is often blocked by phlegm in the throat during use, thereby losing its ventilation function and posing a greater risk of use.
[0004] In order to solve the above-mentioned technical problems, the present application provides an anti-blocking oropharyngeal airway, including a support plate for supporting the oral cavity and throat, with two support plates, between which connecting plates are arranged and vertically connected, and channels for air circulation are formed between the two sides of the connecting plate and the support plates.
[0005] Since the oropharyngeal airway of the present application is designed with a support plate and a connecting plate, an open groove-shaped channel for air circulation can be formed through the connection between the support plate and the connecting plate, thereby solving the problem that the oropharyngeal airway of the prior art is an elliptical hollow plastic tube structure, which is often blocked by phlegm in the throat during use, thereby losing its ventilation function and posing a greater risk of use.

[0012] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example
[0013] The present application relates to an anti-blocking oropharyngeal airway, such as Figure 1-5 As shown, the oropharyngeal airway includes a support plate 1 for supporting the oral cavity and throat. In order to increase the ventilation volume, there are two support plates 1. A connecting plate 2 vertically connected thereto is arranged between the support plates 1. Channels 5 for air circulation are formed between the two sides of the connecting plate 2 and the support plates 1. In order to prevent the airway from being blocked by sputum, the channel 5 is an open groove-shaped structure.
[0014] In order to further enhance the anti-blocking capability of the oropharyngeal airway, through holes 3 are evenly provided on the upper portion of the connecting plate 2, so that the ventilation capability of the oropharyngeal airway is further enhanced, and the overall weight of the oropharyngeal airway can be reduced, thereby reducing the sense of oppression on the oral cavity and throat.
[0015] In order to prevent the oropharyngeal airway from being difficult to remove after it penetrates deep into the throat, an upwardly tilted seesaw 4 is formed at one end of the support plate 1. The two seesaws 4 can abut against the patient's lips by working together, so that by holding the seesaw 4, effective traction can be applied to the oropharyngeal airway, making it easier to quickly pull it out of the throat.
[0016] In order to prevent the oropharyngeal airway from causing friction damage to the oral cavity or throat, the edges of the support plate 1 and the connecting plate 2 are polished with smooth chamfers.
[0017] Since the channels 5 are distributed on both sides of the connecting plate 2, when ventilation is required, diagnostic and treatment instruments such as a gastroscope can be inserted into the patient's throat or abdominal cavity along one of the channels 5, thereby performing diagnosis and treatment without affecting the patient's ventilation operation.
[0018] When in use, the oropharyngeal airway is shaped to match the patient's throat. By holding the seesaw 4, the oropharyngeal airway is slowly inserted along the patient's mouth. Then the lower support plate 1 compresses and fixes the patient's tongue, while the upper support plate 1 lifts the upper part of the patient's mouth. As it continues to go deeper, the patient's throat is stretched to facilitate the patient to perform effective assisted ventilation operations, and the open channel 5 effectively avoids blockage of the oropharyngeal airway.
[0019] It is to be understood that the present application is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present application. In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope protected by the present application.
