Description

gastric tube

technical field

The embodiments of the utility model relate to the technical field of medical devices, in particular to a gastric tube.

Background technique

The gastric tube was first invented and first advocated by American doctors. It is usually inserted through the nostrils, passes through the pharynx, and reaches the stomach through the esophagus. Its function is to evacuate the gas and fluid in the stomach, reduce abdominal distension and reduce the absorption of toxins, so as to keep the gastrointestinal tract empty, prevent vomiting and blood accumulation, and relieve the digestive tract. pressure, which is conducive to the recovery of gastrointestinal function. The application of gastric tube for gastrointestinal decompression has a long history. Clinical experience has proved that gastric tube can not only treat acute gastric dilatation and paralytic ileus, but also save patients with gastric and duodenal ulcer perforation and adhesive intestinal obstruction from surgery. It can be cured after treatment, and it helps to prevent the distention of the anastomotic stoma after gastrointestinal surgery and abdominal distention after various abdominal operations.

Dysphagia is one of the most common functional disorders of post-stroke patients. It is often manifested as: difficulty swallowing food, lack of water, or even inability to initiate swallowing, causing dysphagia and other symptoms, unable to provide the human body with necessary nutrition, and It is easy to cause aspiration and lead to aspiration pneumonia, which is not conducive to the recovery of the patient's body. In more serious cases, it can cause foreign body suffocation and death. For this reason, in addition to swallowing training, patients with dysphagia after stroke need to take a nasogastric feeding diet to ensure the body's nutritional needs when the swallowing function has not recovered. The traditional nasogastric feeding method is to insert the gastric tube from the nose for fixation. The long-term fixation of the gastric tube is likely to cause secondary damage to the patient's nasal cavity. In addition, for patients with simple dysphagia and normal limb muscle strength, or after radiotherapy and chemotherapy for nasopharyngeal cancer and tongue cancer. The image of patients with dysphagia is also greatly reduced. The new type of nasogastric feeding method is to insert the gastric tube through the mouth, give fluid intermittently, eat a meal while inserting it, and pull it out after eating. By patiently guiding the operation, the patient is taught how to fix and determine the method of placing it in the stomach, and the patient can perform the operation by himself, which not only reduces the work of the nursing staff, but also exercises the patient's self-care ability, allowing more patients to return to their families and society; The tube ensures the natural image of the patient, repeated operations for many times, and the swallowing function of the patient has also been activated for many times by starting the swallowing training with laryngeal lift. But it introduces a new problem - the occlusal action of the teeth interferes with the gastric tube.
