Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary tools, in particular to a disposable oropharyngeal airway which is easy to fix. Background Art

[0002] The oropharyngeal 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 temporary artificial airway. 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 curvature. When in use, the oropharyngeal airway is placed in the oral cavity, and its end protrudes 1-2 cm from the incisors.

[0003] After being inserted into the patient's oral cavity, the oropharyngeal airway in the prior art is generally placed in the patient's oral cavity by virtue of the curved shape of the oropharyngeal airway. Figure 1 As shown, the oropharyngeal airway cannot be effectively fixed, and the oropharyngeal airway may be spit out, causing the oropharyngeal airway to shift, affecting the normal use effect, and medical staff need to correct it in time. Utility Model Content

[0004] The utility model aims to provide a disposable oropharyngeal airway which is easy to fix, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solutions: a disposable oropharyngeal airway that is easy to fix, comprising a wing, two fastening strips are hung on the surface of the wing, a clamping strip and a clamping hook are fixedly connected on the surface of the clamping strip, and the clamping strip abuts against the clamping hook;

[0006] The fastening strip can be removed from the wing by means of the snap-on strip and the snap-on hook, and the strap can be disassembled when the strap is not needed;

[0007] A tightening buckle, wherein a rope opening is provided on the surface of the tightening buckle, and a strap is connected in the rope opening, and both ends of the strap are respectively hung with the tightening strip, and two anti-slip sheets are provided on the inner wall of the tightening buckle, and the strap is located between the two anti-slip sheets. The strap is tightened by the anti-slip sheets, and can be flexibly tightened, is easy to adjust, and is suitable for more patients.

[0008] Furthermore, the surface of the wing piece is provided with two hanging interfaces, and the fastening strip is inserted into the hanging interfaces. The fastening strip can be taken out from the hanging interfaces by separating the snap-on strip and the snap-on hook, which makes disassembly and assembly more convenient.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] (1) The strap is clamped by tightening the buckle. After the ventilation tube is placed in the patient's mouth, the oropharyngeal airway can be fixed by pulling the strap. The tightness can also be adjusted to suit different patients, ensuring that the oropharyngeal airway is accurately positioned and not prone to loosening or sliding.

[0011] (2) The connection between the strap and the wing is achieved through the fastening strip. The strap can be removed by moving the snap-on strip and the snap-on hook apart. When it is inconvenient to use the strap, the removal operation is simple and the use is more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0019] See also Figure 2-5 The utility model provides a technical solution: a disposable oropharyngeal airway that is easy to fix, comprising a wing 1, two fastening strips 3 are hung on the surface of the wing 1, a clamping strip 4 and a clamping hook 5 are fixedly connected on the surface of the fastening strip 3, and the clamping strip 4 abuts against the clamping hook 5;

[0020] The fastening strip 3, the clamping strip 4, and the clamping hook 5 are integrally injection molded. The clamping strip 4 made of plastic is elastic and can be stably clamped with the clamping hook 5. The clamping strip 4 has an arched portion to improve the elasticity of the clamping strip 4.

[0021] A tightening buckle 9 is provided with a rope opening 10 on the surface of the tightening buckle 9, and a strap 7 is connected in the rope opening 10. Both ends of the strap 7 are respectively hung with the fastening strip 3. Two anti-slip sheets 11 are provided on the inner wall of the tightening buckle 9. The strap 7 is located between the two anti-slip sheets 11. The two anti-slip sheets 11 are staggered and can stably clamp the strap 7. When the strap 7 is collected to fix the oropharyngeal airway to the patient's oral paper, just tighten the strap 7.

[0022] In this embodiment, if Figure 4 As shown, the surface of the wing 1 is connected to a tooth pad tube 6, and the tooth pad tube 6 is connected to a ventilation tube 2. The width of the occlusal part where the tooth pad tube 6 contacts the teeth is enough to contact two to three teeth, so that the occlusal pressure of the teeth can be evenly distributed to the contacted teeth to avoid toothache. The ventilation tube 2 is inserted into the back of the pharynx to assist the patient's breathing.

[0023] In this embodiment, if Figure 3 As shown, the surface of the wing 1 is provided with two hanging ports 8, and the fastening strip 3 is inserted into the hanging ports 8. The size of the hanging ports 8 is larger than the fastening strip 3, so that the fastening strip 3 can be flexibly adjusted and the fastening strip 3 and the wing 1 can be easily separated.

[0024] In this embodiment, if Figure 4 As shown, the side of the anti-slip sheet 11 is provided with a cone tooth 12, and the cone tooth 12 clamps the strap 7. The cone tooth 12 can increase the resistance of pulling the strap 7, prevent the strap 7 from loosening, and improve the stability of wearing the oropharyngeal airway.

[0025] Specifically, when in use, after the ventilation tube 2 is placed inside the patient's oral cavity, the wing 1 is located outside the mouth to prevent the ventilation tube 2 from being inserted too deeply, the snap-on strip 4 is moved and pressed to separate it from the snap-on hook 5, and the snap-on strip 4 is inserted into the hanging interface 8, and then the snap-on strip 4 is moved to abut against the snap-on hook 5 again to achieve the connection between the strap 7 and the wing 1. After the strap 7 is put on the patient's head, hold the tightening buckle 9 with one hand and pull the strap 7 with the other hand to tie the oropharyngeal airway to the patient's oral cavity to ensure that the ventilation tube 2 will not slip out of the oral cavity.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
