Description

Technical Field

[0001] The utility model belongs to the technical field related to medical care devices, and more specifically, relates to an oropharyngeal airway fixing device. Background Art

[0002] The oropharyngeal airway, also known as the oropharyngeal tracheal airway, is a non-invasive non-tracheal ventilation tube that can prevent the tongue from falling back, and can quickly open the airway and establish a temporary artificial airway.

[0003] like Figure 1 As shown, Figure 1 The figure is a schematic structural diagram of a typical oropharyngeal airway in the prior art.

[0004] Oropharyngeal airways are usually made of rubber or plastic. The main part of the oropharyngeal airway commonly used in clinical practice is an elliptical hollow plastic tube (entering the oral cavity and throat), which has an "S" shape and includes a wing a, a tooth pad part b and a pharyngeal curvature c. The tooth pad part b and the pharyngeal curvature c constitute the main part of the oropharyngeal airway, which needs to enter the oral cavity and be inserted into the throat. The wing a is set at the front end of the tooth pad part b and is located outside the oral cavity when in use to prevent swallowing and excessive insertion. The width of the occlusal part where the tooth pad part b contacts the teeth should be sufficient to contact two to three teeth, so that the tooth occlusal pressure can be evenly distributed to the contacted teeth. The curvature of the inner end of the pharyngeal curvature c adapts to the anatomy of the mouth, tongue and posterior pharynx.

[0005] At present, the oropharyngeal airway entrance mainly relies on the flange a to fix the entire oropharyngeal airway. Since the flange a has a hard structure and a small contact area with the human body, it not only causes discomfort to the user, but also has a very poor fixation effect on the oropharyngeal airway, and the oropharyngeal airway often falls out.

[0033] The present invention provides an oropharyngeal airway fixing device, wherein the oropharyngeal airway includes an S-shaped oropharyngeal airway main body, and a flange is provided at one end of the oropharyngeal airway main body. In the prior art, the oropharyngeal airway is fixed by clamping the flange on the human mouth, but the fixation is very unstable and easily causes the oropharyngeal airway to fall out. In order to solve this problem, the present invention provides an oropharyngeal airway fixing device, which includes: a first part, a fixing device main body 1, the fixing device main body 1 is used to be detachably mounted on the flange of the oropharyngeal airway; a second part, a reinforcement structure 2, the reinforcement structure 2 is provided on the fixing device main body 1, can be in contact with the human face, and is used to reinforce the fixing device main body 1.

[0034] At present, the flange provided on a typical oropharyngeal airway is an elliptical plate structure, and the fixing device body 1 is mounted on the flange in a clip-on manner to achieve connection with the flange. Specifically, the fixing device body 1 is in the shape of an elliptical ring (an elliptical ring structure), and a vent (elliptical opening structure) is provided in the middle of the fixing device body 1. The fixing device body 1 has a certain thickness, which can be twice or three times the thickness of the flange. A card slot 3 is provided on the inner annular surface of the fixing device body 1. The fixing device body 1 is made of elastic material, preferably medical silicone. The fixing device body 1 is stretched open, the card slot 3 is aligned with the flange, and then the fixing device body 1 is released, so that the flange can be clipped into the card slot 3, and the oropharyngeal airway flange is clipped into the card slot 3, so that the fixing device body 1 can be fixedly installed on the oropharyngeal airway. The reinforcement structure 2 is provided on the fixing device body 1 and can contact the human face, so that the oropharyngeal airway is fixed (reinforced) through the fixing device body 1. The reinforcement structure 2 is a strip-like structure with a length between 8 and 15 cm, or it can be longer. Two reinforcement structures 2 are provided and are located on either side of the fixture body 1. The reinforcement structure 2 is made of medical silicone material, which is not only skin-friendly but also safe and comfortable to use. It also allows the reinforcement structure 2 to have a certain degree of adhesion when in contact with the human face, achieving the reinforcement function without the use of "glue-like materials." Of course, the utility model can also use Velcro as the reinforcement structure 2, which is set to be longer. The reinforcement structures 2 on both sides of the fixture body 1 can be connected around the back ends of the human head to achieve reinforcement.

[0036] Specifically, the reinforcing structure 2 is made of medical silicone, and the fixing device body 1 is made of medical silicone. Furthermore, the reinforcing structure 2 is provided on the fixing device body 1 and is integrally formed with the fixing device body 1.

[0037] In order to further improve the comfort of using the present invention, the present invention proposes the following structural optimization: the rear side surface of the fixing device body 1 is used to contact the human face, and the rear side surface of the fixing device body 1 is a smooth arc surface, which can make the fixing device body 1 fit the shape of the human mouth more closely.

[0038] As can be seen from the above, the present invention provides an oropharyngeal airway fixation device. In the present invention, the oropharyngeal airway fixation device comprises: a fixation device body 1, which is used to be detachably mounted on the flange of the oropharyngeal airway; and a reinforcement structure 2, which is provided on the fixation device body 1 and can contact the human face and is used to reinforce the fixation device body 1. Through the above structural design, the fixation device body 1 can be installed on the flange of the oropharyngeal airway, and then the fixation device body 1 is reinforced by the reinforcement structure 2, thereby achieving the reinforcement of the oropharyngeal airway. The present invention solves the problem in the prior art that the oropharyngeal airway is poor in use and easily falls out of the mouth.
