Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a tooth protection cover for an endotracheal tube used for anesthesia. Background Art

[0002] During surgery under anesthesia, a tracheal tube needs to be inserted through the mouth. However, since the patient's teeth are naturally closed after anesthesia, medical staff must first use a mouth brace to hold the patient's mouth open before inserting the tracheal tube. During anesthesia, the patient can easily bite off or flatten the tracheal tube, affecting breathing and hindering surgical operations.

[0003] To address this issue, currently, a rigid tube is commonly used to support the upper and lower teeth, maintaining a certain distance between the teeth and preventing the endotracheal tube from being bitten or flattened by the teeth. However, this method can easily damage the patient's teeth, and the force on the teeth is concentrated on a single tooth or several nearby teeth, which poses a high risk of tooth damage. Furthermore, the stability of the endotracheal tube and the rigid tube is poor, making it easy for the tube to shift, posing a medical risk.

[0004] Therefore, it is necessary to design a tooth protection cover for anesthesia tracheal tube that can effectively protect the tracheal tube and prevent it from being bitten off, and prevent the hard supporting tube from damaging the teeth, and can also fix the tracheal tube well during intubation during anesthesia. Summary of the Invention

[0005] In order to solve the above technical problems, the utility model proposes a tracheal intubation tooth protection cover for anesthesia, which can reduce damage to teeth during general anesthesia, avoid squeezing of the tracheal intubation, ensure smooth oropharyngeal airway, and at the same time can adjust the opening and closing degree of the protection cover, thereby adjusting the gap between the upper and lower tooth covers, reducing the obstruction of the field of vision during the tracheal intubation process, and facilitating the tracheal intubation operation.

The end of the upper brace 1 and the end of the lower brace 2 are connected by an arc-shaped connecting piece 5. The arc-shaped connecting piece 5 is a flexible connecting piece. As can be seen from the figure, two arc-shaped connecting pieces 5 are provided at each end of the upper brace 1 and the lower brace 2, thereby improving the stability of the connection between the upper brace 1 and the lower brace 2, and the connecting piece 5 and the upper brace 1 and the lower brace 2 are an integrated structure.

[0040] The upper braces 1 are provided with an upper alveolar 11 adapted to the maxillary teeth, and the lower braces 2 are provided with a lower alveolar 21 adapted to the mandibular teeth. Specifically, the upper braces 1 and the lower braces 2 are both provided with an outer protective wall 7, an inner protective wall 9, and a bottom protective wall 8.

Figure 2As shown, the height of the inner protective wall 9 is much smaller than the height of the outer protective wall 7, and the height of the outer protective wall 7 gradually increases from the two end portions to the midline position; the upper alveolar 11 and the lower alveolar 21 are both embedded with protective pads 3 that match them, and the cross-section of the protective pad 3 is "L"-shaped. The protective pad 3 is a flexible rubber protective pad 3 made of medical soft rubber or silicone material, which has a good buffering and padding effect on the teeth. Among them, the upper braces 1 and the lower braces 2 are both made of TPE (thermoplastic elastomer) or silicone material.

[0041] The occlusal surface of the upper brace 1 (the bottom surface of the bottom protective wall 8) is provided with a first concave arc surface 12 that penetrates from front to back, and the occlusal surface of the lower brace 2 is provided with a second concave arc surface 22 that penetrates from front to back.

[0047] The upper and lower tooth sockets 11 and 21 are both embedded with protective pads 3 that match them. The cross-section of the protective pad 3 is "L"-shaped, and the protective pad 3 is a flexible rubber protective pad 3 made of medical soft rubber or silicone material, which has a good buffering and padding effect on the teeth. Furthermore, the upper and lower braces 1 and 2 are both made of TPE (thermoplastic elastomer) or silicone material to avoid damage to the teeth caused by hard materials.

[0048] Two regulating air bags 6 are provided between the occlusal surfaces of the upper braces 1 and the lower braces 2, and the regulating air bags 6 are symmetrically arranged near the end connection positions of the upper braces 1 and the lower braces 2; the two ends of the regulating air bags 6 are fixedly connected to the upper braces 1 and the lower braces 2 respectively, and the regulating air bags 6 are provided with an inflation tube 61 connected thereto, one end of the inflation tube 61 is connected to the regulating air bag 6, and the other end is provided with a connecting valve 63 and connected to an external inflation component 62. The two regulating air bags 6 are provided with independent inflation tubes 61, such as Figure 3 As shown, the two inflation tubes 61 form two inflation branches and eventually merge into the main path, and are connected to the inflation component 62 through a connecting valve 63. The inflation component 62 is a negative pressure ball, and can also be other inflation pressure regulating devices to achieve inflation and deflation pressure regulation of the regulating airbag 6.

[0049] The occlusal surface of the upper brace 1 (the bottom surface of the bottom protective wall 8) is provided with a first concave arc surface 12 that penetrates from front to back, and the occlusal surface of the lower brace 2 is provided with a second concave arc surface 22 that penetrates from front to back. The first concave arc surface 12 and the second concave arc surface 22 are arranged corresponding to each other and the cavity formed by the two is adapted to the endotracheal tube, that is, the first concave arc surface 12 and the second concave arc surface 22 both penetrate the bottom of the bottom protective wall 8, and the first concave arc surface 12 and the second concave arc surface 22 cooperate to clamp and fix the endotracheal tube so that the endotracheal tube extends from the outside to the patient's mouth, wherein the first concave arc surface 12 is arranged at the midline of the bottom protective wall 8 of the upper brace 1, and the second concave arc surface 22 is arranged at the midline of the bottom protective wall 8 of the lower brace 2.

[0050] The upper and lower braces 1 and 2 are provided with notches 4 that are adapted to the position and shape of the frenulum of the human body, so that the frenulum of the upper and lower lips of the human body will not be squeezed and compressed by the upper and lower braces 1 and 2 for a long time. Figure 3 As shown, the notch 4 is located at the center line of the outer protective wall 7 .

[0051] Furthermore, the occlusal surface of the upper braces 1, the occlusal surface of the lower braces 2, the first concave arc surface 12, and the second concave arc surface 22 are all provided with an anti-slip layer. The anti-slip layer can specifically be anti-slip particles or anti-slip stripes. The anti-slip layer is provided on the occlusal surface of the upper braces 1 and the lower braces 2, which can effectively prevent sliding or offset between the upper braces 1 and the lower braces 2, and prevent the patient from causing damage to the teeth in an unconscious state. At the same time, the anti-slip layer is provided on the first concave arc surface 12 and the second concave arc surface 22, which can effectively prevent the displacement of the endotracheal tube, ensure the stable fixation of the endotracheal tube, and thus avoid medical risks such as respiratory obstruction caused by position offset of the endotracheal tube.

[0052] During specific use, the negative pressure ball 62 can be manually pressed to inflate the regulating airbag 6 so that the regulating airbag 6 expands. The two ends of the regulating airbag 6 support the upper braces 1 and the lower braces 2 connected thereto, thereby increasing the opening gap between the upper braces 1 and the lower braces 2, making it easier for medical staff to perform tracheal intubation. After the inflation is completed, the negative pressure ball 62 or the external inflation component 62 can be removed, and the connecting valve 63 can be closed to naturally maintain the open state of the mouth without manual maintenance, which can effectively avoid the obstruction of the field of vision and other influences, thereby improving the accuracy and convenience of operation; when the tracheal intubation operation is completed, by opening the connecting valve 63, the gas in the regulating airbag 6 is slowly discharged through the inflation tube 61, and the patient's mouth is slowly closed. Finally, the bottom surface (occlusal surface) of the bottom protective wall 8 of the upper braces 1 and the lower braces 2 are engaged, and the first concave arc surface 12 and the second concave arc surface 22 are closed, which has the effect of clamping and fixing the tracheal tube, so as to achieve stable fixation of the tracheal tube.

[0053] Example 3:

[0054] For Example 3 of the present utility model, Figure 5 Note that, descriptions of parts that are the same as those in Example 2 are omitted and are given the same reference numerals.

By only providing the outer protective wall 7 and the bottom protective wall 8, excessive squeezing and pressure on the teeth can be avoided. At the same time, the restrictions on the size and shape of the teeth are reduced, and the device can be applied to different groups of people, thereby improving the scope of application and practicality.

[0056] Furthermore, the cross-section of the protective pad 3 is "L"-shaped, and the shape and size of the protective pad 3 are adapted to the upper and lower tooth sockets 11 and 21. Specifically, the protective pad 3 is attached to the inner wall side surfaces of the outer protective wall 7 and the bottom protective wall 8.

[0057] In summary, the anesthesia endotracheal tube tooth protection cover provided by the utility model can reduce damage to teeth during general anesthesia, avoid squeezing of the endotracheal tube, ensure smooth oropharyngeal airway, and at the same time, the opening and closing degree of the protection cover can be adjusted to adjust the gap between the upper and lower tooth covers, reduce the obstruction of the field of vision during endotracheal intubation, and facilitate endotracheal intubation operation.

[0058] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
