Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to a stress interruption type instant protection dental tray.
Background
Laryngoscopes are commonly used instruments for otorhinolaryngological operations, and are auxiliary tools for exposing the pharynx and larynx of a patient. In practice, it is necessary for the patient to lie on the operating table and subsequently adjust the patient's head so that the patient's mouth is approximately in line with the patient's pharynx and larynx. After the head of the patient is adjusted, the laryngoscope is inserted from the mouth of the patient and pushed into the specified part, so that the laryngoscope can prop open the pharynx and the larynx of the patient to expose the pharynx and the larynx.
However, in the actual state, because the human tissue has certain elasticity, when the laryngoscope supports the pharynx and the larynx, the laryngoscope is equivalent to a lever. At this point the laryngoscope is in contact with the anterior maxillary tooth, which acts as a support point for the lever. Thus, during surgery, the force on the anterior maxillary tooth is extremely high, up to about 20 kg. Meanwhile, the operation time often reaches 25 minutes or more. This results in anterior maxillary tooth and upper lip injuries as one of the most common complications of support laryngoscope surgery. At present, gauze is mainly used for protecting the maxillary region in China, but the actual protection effect is not ideal.

Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
A stress-interrupting immediate protection tray comprising: a tooth protecting part 1 and an upper lip protecting part 2. The tooth protection 1 comprises a maxillary support plate 12, a load-bearing protective layer 13 and a transfer protective layer 14. Specifically, the bearing protection layer 13 and the transmission protection layer 14 are both made of medical low-temperature thermoplastic plates. Grooves which can be mutually overlapped are formed in the bearing protective layer 13 and the transmission protective layer 14. By means of which the load-bearing protective layer 13 and the transfer protective layer 14 can overlap each other, so that the two grooves together combine to form the tooth-protecting groove 11. The tooth protecting groove 11 corresponds to the tooth shape of the human upper jaw teeth. Preferably, the thickness of the overlap of the load-bearing protective layer 13 and the transfer protective layer 14 is 3mm. When the maxillary teeth are inserted into the tooth protecting groove 11, the maxillary teeth can be fitted with the transfer protecting layer 14. Wherein, the transmission protective layer 14 is provided with a break part 141, and the break part 141 corresponds to the front teeth of the upper teeth. Meanwhile, the intermittent part 141 has an arc shape corresponding to the arrangement of front teeth. Preferably, the length of the discontinuity 141 is 1.5-2.0cm, the width is 0.1-0.3cm, and the height is 0.1-0.2cm. On the other hand, the upper jaw support plate 12 corresponds to the upper jaw of the human body and is connected to the tooth protecting groove 11. When the upper teeth are embedded in the tooth protecting groove 11, the upper support plate 12 is attached to the upper jaw of the human body.
The upper lip protection part 2 is made of a medical low-temperature thermoplastic plate. Preferably, the thickness of the upper lip protector 2 is 1.5mm. The upper lip protector 2 includes an upper lip protector groove 21, a connection plate 22, and an upper lip protector plate 23. The connection plate 22 is disposed between the upper lip guard 21 and the tooth protecting portion 1, one end of the connection plate 22 is connected to the upper lip guard 21, and the other end is connected to the tooth protecting portion 1 such that a certain interval is provided between the upper lip guard 21 and the tooth protecting portion 11. The upper lip guard 23 is provided on a side of the upper lip guard 21 away from the connection plate 22, and the upper lip guard 23 is connected to the upper lip guard 21. The upper lip protecting groove 21 corresponds to the upper lip of the human body, and the groove bottom of the upper lip protecting groove 21 and the groove bottom of the tooth protecting groove 11 are spaced by 1 cm to 1.5cm in the vertical direction. The upper lip can be fitted into the upper lip guard groove 21 when the upper teeth are fitted into the teeth protecting portion 1, and at the same time, the upper lip guard 23 can be fitted to the upper lip.
In practical use, the present utility model is worn on the maxillary part of a human body so that the maxillary teeth are embedded in the teeth guard groove 11 and the upper lip is embedded in the upper lip guard groove 21. At this time, the anterior maxillary tooth is attached to the transfer cover 14. At the same time, the upper jaw support plate 12 is attached to the upper jaw of the human body, and the upper lip guard 23 is attached to the upper lip of the human body.
After the wearing is finished, the operation of the support laryngoscope can be performed. When the laryngoscope is inserted into the throat of a human body, the laryngoscope is attached with the bearing protective layer 13. At this point the laryngoscope continues to apply pressure to the load bearing protective layer 13. Wherein the anterior tooth area of the maxillary teeth is the main area of the laryngoscope exerting pressure. In particular, in the anterior region, the transfer cover 14 is provided with a discontinuity 141. Thus, in the anterior region, the pressure exerted by the laryngoscope on the load-bearing protective layer 13 cannot be applied directly to the anterior teeth via the load-bearing protective layer 14, but is transferred by the load-bearing protective layer 13 to the transfer protective layer 14 and then transferred by the transfer protective layer 14 to all teeth except the anterior teeth. Only if the load bearing protective layer 13 is deformed to the extent that it is in contact with the anterior teeth will the anterior teeth bear a portion of the pressure. In conclusion, the utility model utilizes the bearing protective layer 13 and the transmission protective layer 14 to share most of pressure to other teeth except the front teeth, thereby effectively reducing the burden of the front teeth and avoiding the damage of the maxillary front teeth after operation. Meanwhile, the upper jaw supporting plate 12 is in a fitting state with the upper jaw, so that the contact area between the upper jaw supporting plate 12 and a human body is enlarged, the wearing state of the upper jaw supporting plate is maintained when a supporting laryngoscope operation is performed, and the pressure applied by the laryngoscope is transmitted to the upper jaw of the human body to a certain extent.
On the other hand, the upper lip of the human body is positioned in the upper lip guard groove 21. Because the upper lip of the human body has certain elasticity, and under the action of the connecting plate 22, a certain distance exists between the upper lip protecting groove 21 and the tooth protecting groove 11, so that the upper lip of the human body is in a stretching state. Therefore, the upper lip of the human body is stably limited in the upper lip protecting groove 21 by utilizing the elasticity of the upper lip of the human body, so that the upper lip and teeth are in a separated state by utilizing the upper lip protecting groove 21, and the laryngoscope cannot be directly pressed on the upper lip. At the same time, the laryngoscope is not in direct contact with the upper lip by means of the upper lip guard 23. In summary, the utility model can effectively avoid the upper lip compression, namely friction damage, after operation by utilizing the upper lip protection part 2.
It should be noted that, in fig. 2, the gap between the load-bearing protection layer 13 and the transmission protection layer 14 is only for convenience of illustration, and in a practical state, the load-bearing protection layer 13 and the transmission protection layer 14 are in a mutually attached state.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
