Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary accessories for endotracheal intubation, specifically to an auxiliary sealing device for endotracheal intubation. Background Technology

[0002] Endotracheal intubation support devices, also known as bite blocks or bite plates, are used during endotracheal intubation. After the endotracheal tube is inserted into the trachea through the mouth and glottis, the support device is used to open the patient's mouth and prevent the teeth from biting onto the tube, thus avoiding situations that could lead to insufficient ventilation or reduced ventilation. Currently, most support devices used in endotracheal intubation are solid cylindrical structures with a pair of lateral wings. After intubation, they are wrapped and fixed to the tube with medical tape, and then secured to both sides of the patient's face. However, these devices have the following drawbacks:

[0003] (1) The sealing component is a solid body structure and lacks a structural design that can be adapted to suction, drainage and other tubing;

[0004] (2) The side wall structure of the sealing component is simple, and the insertion tube is prone to slippage, making the insertion depth unstable;

[0005] (3) The side wings of the sealing component are unidirectionally limited, which can be easily pushed up by the surgeon's tongue lifting action due to discomfort or swallowing saliva, causing the intubation tube to move and loosening the fixation between the two. Utility Model Content

[0006] The technical problem this invention aims to solve is to overcome the shortcomings of existing endotracheal intubation sealing devices, such as insufficient adaptability, weak fixation to the intubation tube, and susceptibility to being pushed outwards from the oral cavity. This invention provides an auxiliary sealing device for endotracheal intubation, which, through its central channel design, achieves a tube-adaptive structure for suctioning, drainage, and other operations. Simultaneously, improvements to the sidewall structure ensure a more secure and less prone-to-loosening connection with the intubation tube. The double-layered side wing design provides bidirectional internal and external limiting, preventing the sealing device from being frequently pushed up. Therefore, while improving the effectiveness of the sealing device, its functionality is expanded.

[0007] This endotracheal intubation auxiliary sealing device includes a main structure with an arc-shaped cross-section. The main structure has a central insertion channel for inserting a suction tube or drainage tube. The left or right side of the main structure is concave to form an arc-shaped para-tubular groove, and a bidirectional anti-dislodgement flange is provided in the para-tubular groove. A pair of limiting wings are provided in the middle of the front and rear sides of the main structure. The lower part of the main structure gradually tapers from the front to the rear, forming a tongue depressor on the rear side of the main structure.

[0008] Furthermore, the bidirectional anti-detachment flange includes staggered outgoing flanges and incoming flanges, wherein the outgoing flange faces downward and the incoming flange faces upward.

[0009] Furthermore, the limiting wing includes a toothed outer wing with a larger area located at the top and a toothed inner wing with a smaller area located at the bottom.

[0010] Furthermore, the top of the main structure is provided with a cap for sealing the tube insertion channel.

[0011] This utility model discloses an auxiliary sealing device for endotracheal intubation, overcoming the shortcomings of existing sealing devices used in endotracheal intubation, such as insufficient adaptability, weak fixation to the intubation tube, and susceptibility to being pushed outwards from the oral cavity. Through its central channel design, it achieves a tube-adaptive structure for procedures such as suctioning and drainage; simultaneously, improvements to the sidewall structure ensure a more secure and less prone-to-loosening connection with the intubation tube; and the inner and outer double-layer side wing design provides bidirectional limiting, preventing the sealing device from being frequently pushed up. Thus, it improves the effectiveness of the sealing device and expands its functionality. Attached Figure Description

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] In the description of this utility model, it should be understood that the terms "left", "right", "front", "rear", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0030] Implementation method 1: such as Figures 1 to 6 As shown, this endotracheal intubation auxiliary sealing device includes a main structure 1 with an arc-shaped cross-section. The main structure 1 has a central insertion channel 2 for inserting a suction tube or drainage tube. The left or right side of the main structure 1 is concave to form an arc-shaped para-tube groove 3, and a bidirectional anti-dislodgement flange 4 is provided in the para-tube groove 3. A pair of limiting wings 5 ​​are provided in the middle of the front and rear sides of the main structure 1. The lower part of the main structure 1 gradually tapers from the front to the rear side, forming a tongue depressor 101 on the rear side of the main structure 1. The slightly curved main structure is more adaptable to the shape of the mouth after closure. The insertion channel is used to insert suction tubes, drainage tubes, and other tubes while the endotracheal tube is in place. The para-tracheal groove is used to adapt to the shape of the side of the endotracheal tube. After the two are fixed together with tape, the bidirectional anti-dislodgement flange prevents the tube from sliding inward or outward, ensuring stable insertion depth. The main structure is curved and gradually tapers, allowing its upper part to adapt to the curvature of the palate. The tongue depressor formed below abuts against the anterior part of the tongue. With the help of two pairs of limiting wings, the position of the teeth is limited after the surgeon bites down, thereby preventing the device from being frequently lifted by the tongue movement, which would cause the tube to move and thus loosen the fixation between the two.

[0031] Implementation method 2: such as Figure 7 , 8 As shown, the bidirectional anti-dislodgement flange 4 of this endotracheal intubation auxiliary sealing device includes staggered exit flanges 41 and entry flanges 42. The exit flange 41 is inclined downwards, and the entry flange 42 is inclined upwards. The exit flange with its downward-inclined edge faces the inside of the patient's mouth after insertion, preventing the tube from being pulled outwards; the exit flange with its upward-inclined edge faces the outside of the patient's mouth after insertion, preventing the tube from being inserted inwards. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0032] Implementation method 3: such as Figure 4 , 5 As shown, the limiting wing 5 of this endotracheal intubation auxiliary sealing device includes a larger external toothed wing 51 located at the top and a smaller internal toothed wing 52 located at the bottom. The larger external toothed wing is adapted to the patient's supine position and supports and fixes the entire main structure above the teeth; the smaller internal wing is not easily felt under normal circumstances and is mainly used to immediately block the movement of the main structure outward from the teeth when the tongue depressor is frequently pushed up by tongue lifting movements. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0033] Implementation method 4: such as Figure 6 As shown, the main structure 1 of this endotracheal intubation auxiliary sealing device has a cap 201 at its top for sealing the insertion channel 2. When no tubing is needed, the outer end of the device is sealed to prevent bacteria and viruses from contaminating the respiratory tract through the channel. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0034] This endotracheal intubation auxiliary sealing device overcomes the shortcomings of existing sealing devices used in endotracheal intubation, such as insufficient adaptability, weak fixation to the intubation tube, and susceptibility to being pushed outwards from the oral cavity. Its central channel design achieves a tube-adaptive structure for procedures such as suctioning and drainage; simultaneously, improvements to the sidewall structure ensure a more secure and less prone-to-loosening connection with the intubation tube; and the inner and outer double-layer side wing design provides bidirectional internal and external restraint, preventing the sealing device from being frequently pushed up. Thus, it enhances the effectiveness of the sealing device while expanding its functionality.
