[0002] Painless gastroscopy technology is an innovation on the traditional gastroscopy process, which makes patients quickly enter a state of sedation to light sleep by intravenous injection of an appropriate amount of short-acting anesthetic, so as to keep a state of unconsciousness during the whole examination process and quickly recover consciousness after the examination. However, during the anesthesia stage of painless gastroscopy, some patients may exhibit behaviors such as yawning, speaking, restlessness, sneezing, and even trying to spit out the mouthpiece, etc. Even if a bandage is used for fixation, the mouthpiece may still be displaced or fall off due to the patient's actions, and medical personnel need to continuously support it to ensure that it is in the correct functional position. In particular, for patients with loose teeth, these activities may exacerbate the instability of the teeth, posing a serious risk of tooth loss and misentry into the airway, and further causing adverse consequences. The currently used mouthpiece is mostly made of hard material, and direct contact with the teeth not only exacerbates the risk of tooth loosening, but also may cause accidental lip bruising when the patient yawns or sneezes. In addition, once the patient has an emergency condition during the examination that requires immediate intervention or rescue, and the patient tightly bites the mouthpiece, the difficulty of removing it will be greatly increased, causing inconvenience to emergency treatment. Therefore, developing an auxiliary device that can effectively prevent tooth loss and highly adapt to the needs of painless gastroscopy is a current problem to be solved. SUMMARY

[0025] As Figures 1-6As shown, an oral cavity auxiliary device for gastroscopy includes a mouthpiece 1, an upper soft silicone tooth cover 2 and a lower soft silicone tooth cover 3, and an elastic band 4. The front end of the mouthpiece 1 is provided with a mouthpiece front baffle 108. The upper and lower ends of the mouthpiece front baffle 108 are symmetrically provided with an upper soft silicone tooth cover fixing groove 102 and a lower soft silicone tooth cover fixing groove 103. The left and right ends of the mouthpiece front baffle 108 are symmetrically provided with a right band fixing buckle 104 and a left band fixing buckle 105. The center of the mouthpiece front baffle 108 is provided with a mirror inlet 101. The rear end of the mouthpiece 1 is provided with a hollow holding part 109. The outer side of the holding part 109 is provided with a tooth blocking ring 107. The tooth blocking ring 107 and the mouthpiece front baffle 108 form a space for holding, thereby facilitating the patient's occlusion. The tail end of the holding part 109 away from the mouthpiece front baffle 108 is provided with a tongue depressor 106. The labial side of the upper soft silicone tooth cover 2 and the lower soft silicone tooth cover 3 is provided with a soft silicone tooth cover ring 201 which can be matched with the soft silicone tooth cover fixing groove. The elastic band 4 is provided with a plurality of band fixing holes 401 which can be matched with the band fixing buckle.

[0026] As shown in Figure 3 , 4 , the thickness of the mouthpiece front baffle 108 is 0.2-0.5 cm. The extension length of the holding part 109 away from the mouthpiece front baffle 108 is 4-6 cm. The tail end of the holding part 109 is smoothly transitioned to be flat to form the tongue depressor 106. The distance between the tooth blocking ring 107 and the mouthpiece front baffle 108 is 2-3 cm.

[0027] As shown in Figure 5 , the height of the tongue side of the upper soft silicone tooth cover 2 and the lower soft silicone tooth cover 3 is higher than the height of the labial side. The height of the tongue side is 1.2-2 cm, and the height of the labial side is 0.8-1 cm. Thus, the gum and palate tissue on the tongue side are better protected. The soft silicone part on the tongue side can be softly attached to the gum and palate, thereby avoiding the problem of bleeding caused by the tooth blocking ring 107 rubbing the gum and palate tissue during holding.

[0028] As shown in Figure 6As shown, the elastic bandage 4 has several bandage fixing holes 401 evenly distributed at both ends along the bandage extension direction. The bandage fixing holes 401 are flat ovals in shape, allowing them to engage with the bandage fixing buckles. When in use, the elastic bandage wraps around the back of the patient's head and engages with the two bandage fixing buckles through the bandage fixing holes at both ends for fixation. By adjusting the position of the bandage fixing holes that engage with the bandage fixing buckles, it can adapt to the size of different patients. The elastic bandage 4 is designed to be narrow at both ends and wide in the middle. The wider shape in the middle, which fits against the back of the head, reduces the pressure of the elastic bandage on the back of the head, avoiding skin damage caused by marks or friction.

[0029] In another embodiment, such as Figure 7 As shown, anti-slip textures 110 are provided on the upper and lower surfaces of the bite holding space formed between the tooth retaining ring 107 and the front baffle 108 of the mouthpiece. The anti-slip textures consist of several sets of anti-slip protrusions.

[0030] In another embodiment, the surfaces of the occlusal positions of the upper silicone soft mouthpiece 2 and the lower silicone soft mouthpiece 3 are provided with anti-slip textures, which consist of several sets of anti-slip protrusions. The aforementioned anti-slip textures can further prevent patients from slipping when biting on the mouthpiece, thus avoiding interference with gastroscopy.

[0031] In another embodiment, the mouthpiece front baffle 108 is not flat, but rather a forward-convex arc shape that conforms to the shape of the lips.

[0032] The mouthpiece of this utility model can be made of hard plastic or stainless steel. The hard plastic material is for single use, while the stainless steel material can be repeatedly sterilized and reused; the silicone soft mouthpiece is made of ultra-soft silicone material, which can be fitted according to the patient's tooth shape; the strap is an elastic strap.

[0033] The working method of this utility model is as follows:

[0034] Before the gastroscopy, a suitable mouthpiece is selected based on the patient's condition (adult / child) to ensure comfort and stability. Medical staff assist the patient in placing the silicone mouthpiece over their teeth, with the loop facing outwards. The dentist then correctly places the mouthpiece in the patient's mouth (tongue depressor facing the tongue), with the front baffle pressing against the lips. The patient bites down firmly, and the silicone mouthpiece loop is inserted into the mouthpiece's fixing groove. The straps are then secured with the side buckles to prevent the mouthpiece from slipping out. The dentist inserts the endoscope through the central inlet of the mouthpiece to perform the gastroscopy. After the examination, remove the endoscope, remove the upper and lower silicone soft mouthguard rings from the silicone soft mouthguard fixing groove, and remove the elastic strap from the side strap fixing buckle. For conscious patients, you can ask them to open their mouths to remove the mouthguard, and then remove the silicone soft mouthguard themselves. For patients undergoing painless (anesthesia) examination, you can gently press their chin to remove the mouthguard, or you can wait for the patient to wake up and spit out the mouthguard themselves to remove the silicone soft mouthguard.

[0035] If the patient suddenly changes in the examination process, the patient can press the chin, the silicone soft tooth cover ring is separated from the silicone soft tooth cover fixed groove, the elastic band and the band fixing buckle are separated, the mouthpiece is taken out, and the silicone soft tooth cover can be selected whether to be taken out or not.

[0036] The above embodiment is a preferred embodiment of the present application, but the embodiment of the present application is not limited by the above embodiment, and any change, modification, replacement, combination, simplification made without departing from the spirit and principle of the present application should be an equivalent replacement mode, which is included in the protection scope of the present application.
