Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a tooth protection sleeve for anesthesia. Background Art

[0002] Inserting a tracheal tube through the mouth during general anesthesia is a necessary clinical operation. However, the process of tracheal intubation is very likely to cause damage to the patient's teeth. Since the patient's teeth are in a naturally closed state after anesthesia, medical staff need to first use a support to open the patient's mouth before inserting the tracheal tube into the cavity; at the same time, the patient is prone to biting off or flattening the tracheal tube during anesthesia, which affects breathing and is inconvenient for surgical operations. Currently, hard tubes are generally used in clinical practice to support the upper and lower teeth, so that a certain distance is maintained between the upper and lower rows of teeth to prevent the tracheal tube from being bitten off or flattened by the teeth; however, the above method is very likely to cause damage to the patient's teeth, and the force on the teeth is concentrated on a single tooth or several nearby teeth, which has a high risk of tooth damage, thereby posing a medical hazard.

[0003] In addition, some hospitals use braces to protect teeth. However, existing braces are generally split-type braces, that is, they include separate upper and lower braces. On the one hand, the separate upper and lower braces need to be adjusted separately to fit the teeth, which makes the placement of the braces difficult and time-consuming, affecting the efficiency of tracheal intubation. On the other hand, the separate upper and lower braces are prone to relative offset, resulting in deviation or slippage in their positions, affecting the stability of tracheal intubation placement.

[0004] Therefore, it is necessary to design a tooth protection sleeve for anesthesia that can effectively solve the above problems. Summary of the Invention

[0005] In order to solve the above technical problems, the utility model proposes a tooth protection cover for anesthesia, which has a simple, practical and convenient structure, does not hinder the tracheal intubation operation, can reduce the difficulty of tracheal intubation, and can protect the teeth during the intubation process of general anesthesia, avoid the phenomenon of squeezing the tracheal intubation caused by closed teeth, and ensure smooth oropharyngeal airway.

[0006] The technical solution of the utility model is:

[0007] The utility model provides a tooth protection cap for anesthesia, comprising a U-shaped cap body, wherein the cap body is provided with an upper arc groove adapted to the maxillary teeth and a lower arc groove adapted to the mandibular teeth;

[0008] A front-to-back accommodating through hole is provided at the center of the mouthpiece body, and the accommodating through hole is adapted to the endotracheal tube.

[0009] Preferably, the upper arc groove and the lower arc groove each include an outer groove wall located on the outside, an inner groove wall located on the inside, and a bottom groove wall connected to the outer groove wall and the inner groove wall;

[0010] The height of the outer groove wall is greater than the height of the inner groove wall.

[0011] Preferably, the height of the outer groove wall gradually decreases from the center to the two ends.

[0012] Preferably, soft rubber pads are fixedly embedded in the upper arc groove and the lower arc groove.

[0013] Preferably, the soft rubber pad includes an inner pad in contact with the inner groove wall, an outer pad in contact with the outer groove wall, and a bottom pad in contact with the bottom groove wall, and the bottom pad is connected to the inner pad and the outer pad.

[0014] The height of the inner protective pad is not greater than the height of the inner groove wall, and the height of the outer protective pad is not greater than the height of the outer groove wall.

[0015] Preferably, tooth grooves are provided on the inner side of the outer pad to fit against the outer side of the teeth to prevent slipping.

[0016] Preferably, a "V"-shaped depression adapted to the lip frenulum is provided at the center position of the outer groove wall of the upper arc groove and the lower arc groove.

[0017] Preferably, the inner wall of the accommodating through hole is provided with any one of anti-slip ribs, anti-slip patterns, or anti-slip particles.

[0018] Preferably, the cross section of the accommodating through hole is circular or polygonal.

[0019] Compared with the prior art, the present invention has the following advantages and effects:

[0020] (1) The "U"-shaped brace body with both upper and lower arc grooves can protect both maxillary and mandibular teeth at the same time, reducing damage to the teeth during tracheal intubation. Compared with the separate braces in the existing technology, the brace is more stable and there will be no relative offset between the protective sleeves, thus avoiding the phenomenon of tracheal intubation movement or even detachment;

[0021] (2) A receiving hole is provided at the center of the main body of the braces, and the receiving hole is adapted to the tracheal tube. The tracheal tube can be inserted into the oral cavity through the receiving hole to complete the intubation, effectively avoiding contact and collision between the tube body and the teeth during the intubation process, thereby playing a role in protecting the teeth.
