AI Technical Summary
The existing intubated oropharyngeal ventilation duct is prone to fall off during use and it is difficult to fix the tracheal intubation, resulting in instability of ventilation.
A cannulated oropharyngeal ventilation channel including a tooth pad and a pharyngeal bending is designed. A rubber block and a through hole are installed in the tooth pad. The tracheal intubation can be inserted into the through hole. The elasticity of the rubber block and the through hole are designed to prevent the cannula from falling off; the combination of non-woven fabric and fixing belt prevents the air duct itself from falling off.
It effectively prevents the fall of the tracheal intubation and ventilation duct, ensuring the stability and safety of ventilation.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical auxiliary equipment, in particular to an anti-drop-out intubation type oropharyngeal airway. Background Art
[0002] The pharyngeal airway is a non-invasive ventilation tube that is not a tracheal tube. It can prevent the tongue from falling back, quickly open the airway, and establish a temporary artificial airway. The existing commonly used clinically includes a tooth pad part and a pharyngeal bend part, which has no fixed structure and may fall out of the patient's mouth in clinical practice. Moreover, after the temporary airway is established, some patients still need tracheal intubation. The tracheal intubation enters directly from the pharyngeal airway, and the tracheal intubation cannot be fixed, which is easy to cause the tracheal intubation to move and fall off. Summary of the invention
[0003] In view of the shortcomings of the prior art, the utility model provides an anti-dropout intubation oropharyngeal airway.
[0004] The technical solution of the utility model is achieved as follows: an anti-slip intubation oropharyngeal airway comprises a tooth pad portion and a pharyngeal curvature portion, a rubber block is movably installed in the tooth pad portion, at least one through hole is provided on the rubber block, a baffle is fixedly connected to the outside of the tooth pad portion, a non-woven fabric is fixedly connected to the inner side of the baffle, both ends of the non-woven fabric are connected to an extension portion, a fixing belt is connected to the extension portion, one end of the fixing belt is fixedly connected to the extension portion, the other end of the fixing belt is movably inserted into an adjusting column, a through hole two is provided at the center position of the adjusting column, and the adjusting column is fixedly connected to the extension portion.
[0005] Positioning grooves are symmetrically arranged on the left and right sides of the rubber block, and positioning blocks are symmetrically arranged inside the tooth pad part, and the positioning blocks and the positioning grooves are matched with each other.
[0006] The baffle is made of silicone.
[0007] A connecting belt is inserted into the adjusting column, one end of the connecting belt is fixedly connected to the extending portion, and the other end of the connecting belt is also fixedly connected to the extending portion.
[0008] The end of the free end of the fixing belt is fixedly connected to the limiting column.
[0009] The technical solution of the utility model has the following positive effects: a rubber block is installed on the tooth pad part of the oropharyngeal airway of the utility model, and a through hole one is opened on the rubber block, through which a tracheal tube can pass, and the rubber block has a certain elasticity, and the diameter of the through hole one is slightly smaller than the diameter of the tracheal tube, which can prevent the tracheal tube from falling off; extension parts are connected to both ends of the non-woven fabric, and the extension parts are used to fix the fixing belt, which can be worn on the ear to prevent the oropharyngeal airway from falling off, and the free end of the fixing belt passes through the adjustment column, and the tightness of the fixing belt is adjusted by tightening the fixing belt.

[0014] As Figures 1 to 4 shown, a detachable intubated oropharyngeal airway, the oropharyngeal airway includes a dental pad part 1 and a pharyngeal bending part 2. A rubber block 3 is movably installed in the dental pad part 1. At least one through hole 4 is formed in the rubber block 3. An external baffle 5 is fixedly connected to the dental pad part 1. A non-woven fabric 6 is fixedly connected to the inner side of the baffle 5. Both ends of the non-woven fabric 6 are connected with extension parts 7. A fixing belt 8 is connected to the extension parts 7. One end of the fixing belt 8 is fixedly connected to the extension part 7, and the other end of the fixing belt 8 movably passes through an adjusting column 9. A through hole 10 is formed at the central position of the adjusting column 9. The adjusting column 9 is fixedly connected to the extension part 7.
[0015] Specifically, the pharyngeal bending part 2 is inserted into the throat, and the dental pad part 1 is located at the tooth position. The baffle 5 plays a limiting role. For a patient who needs tracheal intubation, the tracheal intubation is inserted into the through hole 4. The rubber block 3 has a certain elasticity, and the diameter of the through hole 4 is slightly smaller than the diameter of the tracheal intubation, which can prevent the tracheal intubation from falling off. The non-woven fabric 6 is attached to the skin of the mouth part. Extension parts 7 are provided on both sides to connect the fixing belts 8. The fixing belts 8 on both sides are hung on the ears, and the fixing belts 8 are tightened to become thinner and move in the through hole 10 of the adjusting column 9, thereby adjusting the tightness of the fixing belts 8; the fixing belts 8 are made of spandex material and will not move in the through hole 10 when not tightened.
[0016] Positioning grooves 11 are symmetrically formed on the left and right sides of the rubber block 3, and positioning blocks 12 are symmetrically arranged inside the dental pad part 1. The positioning blocks 12 and the positioning grooves 11 cooperate with each other. Specifically, the contact area is increased through the rubber block 12 and the positioning grooves 11, and the rubber block 3 is more firmly connected.
[0017] The baffle 5 is made of silica gel material; specifically, the baffle 5 is made of silica gel material, and the silica gel material is relatively soft, which increases the comfort.
[0018] A connecting belt 13 is passed through the adjusting column 9, one end of the connecting belt 13 is fixedly connected to the extension part 7, and the other end of the connecting belt 13 is also fixedly connected to the extension part 7; specifically, the adjusting column 9 is fixedly connected to the extension part 7 through the connecting belt 13, and the adjusting column 9 is located at the position of the extension part 7, so that it can avoid being located behind the ear, thereby increasing comfort.
[0019] The free end of the fixing belt 8 is fixedly connected to a limiting column 14 ; the limiting column 14 limits the free end of the fixing belt 8 to prevent it from coming out of the adjusting column 9 .
