Description

Gastrointestinal decompression device for general surgery

technical field

The invention relates to the field of medical devices, in particular to a gastrointestinal decompression device for general surgery.

Background technique

The main purpose of gastrointestinal decompression is to completely absorb the contents of the stomach through an indwelling gastric tube, so as to empty the gastric cavity and reduce abdominal distension. Reducing the inflow of gastric and intestinal fluids to the distal duodenum and jejunum can reduce the irritation to the gallbladder, pancreas, intestinal tract and other digestive organs, and is beneficial to relieve symptoms.

Patients with clinical pancreatitis can indwell a gastric tube, which can reduce the stimulation of gastric juice to pancreatic juice and better control pancreatitis. During the treatment of intestinal obstruction, due to intestinal blockage, a large amount of gastric juice still flows into the intestinal tract, resulting in a gradual increase in intestinal pressure. Gastrointestinal decompression is beneficial to relieve intestinal obstruction. After indwelling gastrointestinal decompression, the changes of the disease can also be observed through the drainage. The drainage is bloody, indicating that there is blood in the gastric juice, and the fecal drainage indicates that the obstruction site is low. Therefore, in addition to the therapeutic effect of gastrointestinal decompression, it also has a certain diagnostic effect.

The existing gastrointestinal decompression device will pump out the patient's stomach content during the process of decompressing the patient's stomach, and the patient's stomach is always secreting gastric acid.
