[0002] During clinical gastroscopy, the gastroscope tube needs to be used with a gastroscope mouthpiece. The gastroscope mouthpiece is mainly used to facilitate the gastroscope tube to enter the patient's mouth smoothly and prevent the patient from biting the gastroscope tube. The existing gastroscope mouthpiece has a relatively simple structure and effect. The mouthpiece is directly inserted into the patient's mouth. When the patient opens his mouth for a long time, he is prone to oral fatigue and secretion of a lot of sputum. However, the current mouthpiece is not convenient for patients to relieve oral fatigue through oral activities, resulting in more and more sputum, causing patients to retch, reducing the efficiency of gastroscopy.

[0004] The cited patent literature also has the same problem. Patients are prone to oral fatigue and secretion of a large amount of sputum when their mouths are open for a long time. The mouthpiece is not convenient for patients to relieve fatigue through oral activities, resulting in more and more sputum, causing patients to retch, and reducing the efficiency of gastroscopy.

DETAILED DESCRIPTION

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0026] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0027] This embodiment discloses Figures 1 to 4 A mouthpiece for clinical gastroscopy shown in the figure includes a mouthpiece assembly 1 used for gastroscopy of patients. The mouthpiece assembly 1 includes a mouthpiece main body guard plate 2 and a mouthpiece main body tube 3 connected centrally. The mouthpiece main body guard plate 2 is an arc-shaped structure, and has anti-scratch chamfered portions 9 at both ends of the mouthpiece main body guard plate 2. Headband strap through holes 6 for adapting and installing a headband are provided on both sides of the inner wall of the mouthpiece main body guard plate 2, which can help to wear it on the head, prevent the mouthpiece assembly 1 from falling off, and improve its wearing stability.

[0028] The interior of the bite device body guard plate 2 is provided with an installation opening 4 for installing the bite device bite body tube 3. The outer wall of the bite device body guard plate 2 facing the bite device bite body tube 3 is provided with a stepped recess in the installation opening 4, and an elastic extrusion buffer component for elastically buffering the bite device bite body tube 3 in the patient's mouth is installed in the stepped recess. The elastic extrusion buffer component includes a rubber buffer ring pad 12 bonded to the inner wall of the stepped recess and an extrusion spring 13 inserted in the rubber buffer ring pad 12. Both ends of the extrusion spring 13 elastically abut against the inner walls of the bite device body guard plate 2 and the bite device bite body tube 3 respectively. This elastic extrusion buffer component is installed at the connecting end of the bite device bite body tube 3 and the bite device body guard plate 2.

[0029] The elastic buffering of the rubber buffer ring pad 12 and the extrusion spring 13 of the elastic extrusion buffer component can help the bite body tube 3 of the mouthpiece to move in the patient's mouth with elastic buffering, thereby replacing the traditional rigid structure. It can not only reduce the damage caused by the patient's mouth being squeezed by hard objects, but also help the patient's mouth to move slightly after being tired from opening the mouth for a long time. The elastic effect can facilitate the movement, thereby preventing the patient from retching and improving the use efficiency and experience.

[0030] A palate supporting secretion collecting component 10 is connected to the upper part of one end of the mouthpiece main body tube 3 facing away from the mouthpiece main body guard plate 2. The palate supporting secretion collecting component 10 extends into the oral cavity and elastically abuts against the upper palate upward. The palate supporting secretion collecting component 10 includes a supporting mesh piece 8, a secretion collecting cotton pad 14 and a supporting anti-leakage pad 15 which are respectively connected to the outer wall of the mouthpiece main body tube 3 from top to bottom. The supporting mesh piece 8 is bonded to the top surface of the secretion collecting cotton pad 14, and the supporting anti-leakage pad 15 is bonded to the bottom surface of the secretion collecting cotton pad 14.

[0031] When the patient opens his mouth for a long time, oral fluid is easily secreted in the oral cavity. At this time, the liquid flowing out from the upper palate can flow from the supporting mesh plate 8 into the secretion liquid collecting cotton pad 14 and be collected by the secretion liquid collecting cotton pad 14. The supporting mesh plate 8 can support the upper palate and reduce the direct contact between the upper palate and the secretion liquid collecting cotton pad 14, thereby preventing the secretion liquid collecting cotton pad 14 from rubbing against the upper palate and causing discomfort. The supporting mesh plate 8 is a medical surgical mesh and will not cause discomfort to the patient. At this time, the supporting leak-proof pad 15 can prevent the collected secretion liquid from falling.

[0032] A tongue depressor 7 is connected to the outer wall of the mouthpiece main tube 3 of the mouthpiece below the upper jaw support secretion collection component 10. The tongue depressor 7 can press down the tongue to prevent the peristalsis of the tongue from affecting the insertion of the gastroscope tube.

[0033] A drainage tube 5 for absorbing oral secretions is connected to the outside of the mouthpiece body guard plate 2 and extends into the mouthpiece body tube 3. A secretion collection recess 11 is provided on the inner bottom wall of the mouthpiece body tube 3 and at one end facing away from the mouthpiece body guard plate 2. The extended end of the drainage tube 5 extends into the secretion collection recess 11.

[0034] Specifically, the outside of the drainage tube 5 cooperates with a medical suction pump to collect the secretions in the oral cavity, and the sputum first flows into the secretion collection recess 11 located deep in the oral cavity and is discharged through the drainage tube 5. The secretion collection recess 11 can collect the sputum, thereby speeding up the discharge of the sputum and improving the efficiency of the patient's gastroscopy.

[0035] How it works

[0036] The mouthpiece assembly 1 of the mouthpiece for clinical gastroscopy is worn on the head through a head-wearing rope, and the mouthpiece main body tube 3 of the mouthpiece extends into the oral cavity, and the supporting mesh sheet 8 is supported on the upper jaw. When the patient opens his mouth for a long time, oral fluid is easily secreted in the oral cavity, and at this time, the liquid flowing out of the upper jaw can flow from the supporting mesh sheet 8 into the secretion liquid collecting cotton pad 14, and is collected by the secretion liquid collecting cotton pad 14, and the supporting anti-leakage pad 15 can prevent the collected secretion liquid from falling;

[0037] The outside of the drainage tube 5 cooperates with a medical suction pump to collect the secretions in the oral cavity, and the sputum first flows into the secretion collection recess 11 located deep in the oral cavity and is discharged through the drainage tube 5. Under the elastic buffering of the rubber buffer ring pad 12 and the extrusion spring 13, the bite body tube 3 of the mouthpiece moves elastically in the patient's mouth to relieve fatigue.
