Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a catheter device for treating GERC. Background Art

[0002] Gastroesophageal reflux cough (GERC) is a chronic cough caused by the reflux of gastric contents into the esophagus and irritation of the esophagus and throat. This disease is common worldwide and seriously affects the quality of life of patients. Clinically, the treatment of GERC usually includes drug therapy and lifestyle changes, such as the use of proton pump inhibitors (PPIs) to reduce gastric acid secretion, and lifestyle adjustments such as avoiding lying down before eating. However, some patients do not respond well to these traditional treatments, resulting in persistent symptoms. There is an urgent need for a more effective treatment device and method to suppress the cough caused by GERC and improve the quality of life of patients.

[0003] In clinical practice, multi-channel impedance pH monitoring is a commonly used examination method for diagnosing gastroesophageal reflux disease (GERD) and related diseases. This technology evaluates the frequency and severity of gastric reflux by monitoring the pH value and impedance changes in the esophagus. However, in actual operation, the cough reflex of some patients will temporarily disappear when undergoing multi-channel impedance pH monitoring. The mechanical stimulation of the catheter to the pharynx and esophagus may play a certain role in suppressing the cough reflex.

[0004] Based on this clinical observation, the present invention aims to design a catheter device for treating GERC, which effectively suppresses the cough reflex through a combination of mechanical stimulation and drugs, thereby improving the patient's symptoms. The design of the device takes into account both the patient's comfort and the ease of operation, and aims to provide a new solution for clinical treatment, improve the treatment effect, and improve the patient's quality of life.
