Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an improved mouth pad for endoscopic examination. Background Art

[0002] During gastroscopy examination and treatment, patients need to place a mouth pad (with only one opening in the middle) in their mouth before the examination to help them press down their tongue and open their mouth to facilitate the smooth passage of the endoscope through the mouth, while also protecting the endoscope and preventing it from being damaged by the teeth.

[0003] The existing dental pads have the following problems in clinical use:

[0004] 1. Because there is a cavity in the middle, gas in the stomach is easy to overflow. When the doctor needs to use gas to open the stomach cavity to observe the mucosa during the examination, some patients will be affected by the gas overflow;

[0005] 2. The entrances to the respiratory tract and digestive tract are close to each other. Many elderly patients have loose teeth or dentures. If they fall out during the examination, there is a risk of them falling into the respiratory tract. In addition, the mouthpiece is not easy to wear and fix during use.

[0006] 3. During clinical use, when the endoscope has reached the gastric cavity, if the patient has a lot of gastric fluid that refluxes, or a lot of oral secretions that are prone to accidental aspiration, prompt and rapid suction is required. The doctor needs to withdraw the endoscope to the oral cavity, use the endoscope to aspirate the oral fluid, or directly withdraw it completely from the body, and then insert a suction tube to aspirate.

[0007] Therefore, we propose an improved mouth pad for endoscopic examination. Utility Model Content
