[0001] The present invention relates to the field of cricopharyngeal muscle rehabilitation. Specifically, it relates to a visual manometry balloon catheter for cricopharyngeal muscle assessment and rehabilitation training. Background Art

[0002] Cricopharyngeal achalasia is manifested as dysphagia during eating, where food stays in the oropharynx and cannot enter the esophagus. Therefore, the meal time is greatly extended. If the food is liquid, it will be aspirated into the respiratory tract after swallowing, causing choking. At the same time, there will be a feeling of food blockage and foreign body in the throat when swallowing food.

[0003] In the prior art, a soft endoscope insertion tube is mainly arranged in the balloon catheter to solve the problem of blind intubation and the invisibility during the intubation process. However, when treating the patient's esophagus, the tube still needs to be pulled to stimulate the muscles at the patient's esophageal area. The existing intubation cannot effectively control the insertion depth, and the pulling length is also handled according to the doctor's personal experience. Therefore, the limitations of the existing catheter during use are relatively high.

[0004] Therefore, those skilled in the art provide a visual manometry balloon catheter for cricopharyngeal muscle assessment and rehabilitation training to solve the problems raised in the above background art. Summary of the Invention
