Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical apparatus and instruments, especially to a maintain airway patency prevent tongue falling back gastroscopy bite. BACKGROUND

[0002] When doing gastroscopy, it is painful and time-consuming, and patients are easy to bite gastroscopy pipeline, which leads to gastroscopy damage, affects breathing, and even causes asphyxia. In order to reduce the pain of patients, intravenous anesthesia is often used before gastroscopy, that is, painless gastroscopy. At the same time, in order to avoid patients biting gastroscopy pipeline, medical bite is used to open teeth to support oral cavity to prevent patients from biting gastroscopy, which leads to gastroscopy damage.

[0003] Publication No. CN 215128367 U discloses a maintain airway patency prevent tongue falling back gastroscopy bite, the arc-shaped plate is bent downward, which matches the tongue root in the throat cavity of the human body, so that when tracheal intubation is performed on obese patients, the curvature of the arc-shaped plate is in close contact with the tongue root, the tongue is pressed downward by the arc-shaped plate, and the pharyngeal cavity stenosis caused by obesity is relieved, and rapid intubation is achieved when tracheal intubation is performed.

[0004] The above-mentioned prior art and the existing gastroscopy bite are both restrained in the oral cavity of the patient by an elastic band during use. However, in the specific use process, the bite needs to be placed in the oral cavity of the patient first, then the head of the patient is lifted, and then the elastic band is sleeved on the head of the patient. During the process of lifting the head of the patient, the bite in the oral cavity of the patient is easy to fall off. The size of the head of different patients is different. When the elastic band is short, the elasticity is large, which is easy to cause discomfort. When the elastic band is long, the elastic band is easy to fall off when the head of the patient and the pillow rub. UTILITY MODEL CONTENTS

[0026] Embodiment one

[0027] A gastroscopy bite to maintain airway patency and prevent tongue posterior displacement includes a fixation plate 1, a bite sleeve 2 fixed to one side of the fixation plate 1, a tongue depressor 3 fixed to the bottom of the bite sleeve 2 away from the fixation plate 1, side straps 4 installed on both sides of the fixation plate 1, grooves 5 opened in the side straps 4, a connecting strap 6 slidably connected in the grooves 5, a positioning component for positioning the connecting strap 6 and the side strap 4, and an ear strap 7 fixed to one side of the connecting strap 6, a restraint component for restraining it to the patient's ear.

[0028] Specifically, the positioning component includes a first rough surface 9 and a first hook surface 8 disposed on one side of the connecting strip 6, with the first hook surface 8 close to the end of the connecting strip 6. The first hook surface 8 and the first rough surface 9 are bonded together. A shielding cloth 11 is fixed on the connecting strip 6, and a second hook surface 12 is disposed on one side of the shielding cloth 11, with the second hook surface 12 bonded to the first rough surface 9. A second rough surface 10 is disposed on the other side of the connecting strip 6, and the second rough surface 10 and the first hook surface 8 are symmetrically disposed. The second hook surface 12 can also be bonded to the second rough surface 10.

[0029] In use, first adjust the length of the side strap 4 and the connecting strap 6 according to the distance from the patient's ear to their mouth. First, pull the covering cloth 11 to separate the second hook surface 12, the second rough surface 10, and the first rough surface 9. Then, pull one end of the connecting strap 6 to separate the first hook surface 8 and the first rough surface 9. You can then pull the connecting strap 6 to make it slide within the groove 5, thereby adjusting the length of the connecting strap 6, which is equivalent to adjusting the distance between the ear strap 7 and the fixing plate 1. After adjustment, fold the connecting strap 6 to make the first hook surface 8 and the first rough surface 9 adhere together. Fold the covering cloth 11 again so that the second hook side 12 and the second rough side 10 are bonded together. The second hook side 12 can also be bonded to the first rough side 9. It should be noted that when the first hook side 8 and the first rough side 9 are bonded together, the connecting strap 6 is fixed. When the covering cloth 11 is folded, the second hook side 12 and the second rough side 10 are also bonded together, so that the connecting strap 6 is fixed more firmly. After the second hook side 12 and the first rough side 9 are bonded together, the covering cloth 11 covers the excess first rough side 9, so as to avoid the first rough side 9 causing discomfort to the patient's face.

[0031] A gastroscopy bite block for maintaining airway patency and preventing tongue posterior displacement, based on Embodiment 1, includes a restraint assembly comprising a cylindrical tube 13. The top and bottom of the cylindrical tube 13 are provided with through grooves 14 for the ear loops 7 to pass through. Two cylindrical rods 16 are slidably connected inside the cylindrical tube 13. The cylindrical rods 16 are provided with slots 15 for the ear loops 7 to pass through. A spring 17 is provided inside the cylindrical tube 13, and the two ends of the spring 17 are respectively fixed to the corresponding cylindrical rods 16. When the spring 17 is not under force, the slots 15 and through grooves 14 are staggered.

[0032] When the length between the ear band 7 and the fixing plate 1 meets the distance from the patient's ear to the oral cavity, the mouthpiece 2 and the tongue depressor 3 are first placed in the patient's oral cavity, then the ear band 7 is hung on the patient's ear, and then the two cylindrical rods 16 are pressed, so that the two cylindrical rods 16 slide in the cylindrical barrel 13 and approach each other, when the slot hole 15 and the through slot 14 are overlapped, the cylindrical barrel 13 can be moved, the cylindrical barrel 13 is moved to the patient's ear, the cylindrical rods 16 are loosened, the two cylindrical rods 16 are driven away from each other under the action of the elasticity 17, so that the slot hole 15 and the through slot 14 are dislocated, that is, the cylindrical barrel 13 and the ear band 7 are fixed, so that the ear band 7 covers the patient's ear, avoiding the falling of the ear band 7, that is, increasing the stability.
