Description

Multifunctional catheter for dysphagia patients

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a multifunctional catheter for dysphagia patients.

Background

Dysphagia refers to the inability of food to pass from the mouth to the stomach due to nerve damage associated with swallowing or damage to the swallowing organs that results in damage to one or more stages of swallowing, and is commonly found in people with stroke, craniocerebral trauma, parkinson's disease, and the like. Patients with dysphagia can not independently treat sputum and oral secretion due to the impaired swallowing function, and inflammation is caused once the sputum or secretion enters the lung, so that the patients with dysphagia need a sputum suction tube to clean the sputum and secretion in the throat, and meanwhile, due to the impaired swallowing function, partial patients with dysphagia also need a nutrition tube to send fluid food to the stomach of the patient, and the nutrition tube is sometimes blocked when the fluid food is sent to the stomach of the patient.
