[0002] During intraoral procedures such as endotracheal intubation, gastroscopy, transesophageal echocardiography, and fiberoptic bronchoscopy, there is a risk of teeth accidentally falling into the airway. Typically, healthcare professionals rely on caution and experience to minimize this risk, but a specific and effective protective tool is lacking. If a tooth does fall into the airway, it can cause severe airway obstruction and even endanger the patient's life, requiring emergency airway foreign body removal, causing significant pain and risk to the patient.

[0023] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0024] This invention provides an intubation aid device to prevent loose teeth from falling into the airway, such as... Figures 1-4As shown, it includes a protective shield 2, which is made of a soft, non-toxic, transparent, and somewhat elastic material, such as medical silicone. The transparent protective shield 2 does not affect the observation of the oral cavity. One end of the protective shield 2 has an opening in the middle. The opening of the protective shield 2 is fitted over the outside of one end of the hollow tube 7 and fixedly connected together. The two ends of the hollow tube 7 are a first opening and a second opening, respectively. In use, the first opening is placed inside the mouth near the base of the tongue, and the second opening is placed outside the mouth near the lips. When unfolded, the protective shield 2 forms a bowl-shaped structure recessed towards the other end of the hollow tube 7.

[0025] Hollow tube 7 is a cylindrical structure made of relatively hard and thick plastic material. Its length is the vertical distance from the incisor to the posterior alveolar bone. Its surface is smooth, allowing instruments such as endotracheal tubes and gastroscopes to pass through it without restriction.

[0026] The outer side of the first opening of the hollow tube 7 and the protective baffle 2 can be integrally formed; or the outer side of the first opening of the hollow tube 7 can be connected to the flange 1 by threads, and the flange 1 is used to fix the protective baffle 2 at the first opening of the hollow tube 7, with the protective baffle 2 located between the outer side of the first opening of the hollow tube 7 and the flange 1.

[0027] A fixing plate 4 is provided on the outer side of the second opening of the hollow tube 7, and there is a fixing hole 8 on each side of the fixing plate 4. The second opening of the hollow tube 7 and the fixing plate 4 can be fixedly connected, or they can be an integrally formed structure.

[0028] Multiple support guide wires 3 are closely attached to the inside of the protective baffle 2 (i.e., the inner wall of the recessed side), and the two ends of each support guide wire 3 are located on the inner and outer rings of the protective baffle 2 (i.e., the opening position and the outer ring edge position of the protective baffle 2). They can be made of resin material with certain toughness and elasticity, and are pre-made with a certain curvature to form a strip-shaped arc structure that matches the curvature of the palate of the human mouth, so as to support and maintain the arc structure of the protective baffle 2.

[0029] A hollow ring tube 5 is located on the outer ring of the protective baffle 2. A wire 6 is threaded inside the hollow ring tube 5. The opening and closing of the protective baffle 2 is controlled by tightening or loosening the wire. The two ends of the wire 6 can be knotted or fixed by passing through the fixing holes 8 on the fixing plate 4. The wire 6 is wound around the hollow ring tube 5 once and then leads out two ends for fixing in the fixing holes 8.

[0030] This invention utilizes the physical barrier effect of the protective sleeve to form an effective protection within the oral cavity. By selecting appropriate materials and shapes, it ensures that the protective sleeve (i.e., the intubation auxiliary device of this invention) can be comfortably placed and fit within the oral cavity. Even if a tooth falls out during the procedure, it can be caught by the protective shield, effectively preventing the tooth from falling into the airway.

[0031] The usage process of this utility model is as follows:

[0032] When not in use, the device of this invention has the thread 6 pulled taut, passed through the fixing hole 8, and knotted to maintain the protective baffle 2 in a closed state with the outer ring facing downwards (towards the fixing plate 4) and inwards (towards the outer wall of the hollow tube 7). Before intraoral procedures, the patient bites down on the hollow tube 7, the fixing plate 4 is secured to the outside of the lips, and the knot of the thread 6 is loosened. The protective baffle 2 automatically opens under its own elasticity and the elasticity of the supporting guidewire 3, and maintains its arc-shaped structure under the support of the supporting guidewire 3. The two ends of the thread 6 come out from the fixing hole 8 and can be respectively placed on the patient's ears for fixation. Endotracheal intubation, transesophageal echocardiography probes, gastroscopy probes, and other instruments are operated normally through the hollow tube 7. After the operation is completed, the thread 6 is pulled back to retract the device and it is removed.
