Description

Multifunctional jejunostomy tube

Technical Field

The utility model belongs to the technical field of medical treatment auxiliary devices, concretely relates to both can satisfy the patient to the needs of nutrition, can avoid the stomach tube to the stimulation of throat again, reduce the incidence of complication such as dyspnea, do benefit to the recovered multi-functional jejunum fistulation pipe of patient.

Background

Esophageal cancer is a common tumor in digestive tract tumors, and the common treatment mode of esophageal cancer is resection of esophagus and reconstruction of digestive tract; however, since esophageal anastomotic fistulas are one of the serious complications after esophageal resection and esophageal reconstruction, an indwelling gastric tube and parenteral nutrition therapy are often required after surgery. The intestinal mucosa atrophy, the intestinal epithelial cell proliferation is reduced, the apoptosis is increased, the intestinal mucosa permeability is increased, and bacteria in the intestinal tract easily enter the body to cause systemic inflammatory reaction; at the same time, the increase in permeability of the intestinal mucosa is likely to cause abdominal pain and diarrhea after nutrition administration, and thus, early enteral nutrition administration is very necessary. Enteral nutrition is beneficial to the effective absorption of gastrointestinal tracts, promotes gastrointestinal peristalsis, maintains the barrier effect of intestinal mucosa, reduces the imbalance phenomenon of intestinal flora, and enables the gastrointestinal function of patients to recover quickly, so that the administration of the enteral nutrition is frequently carried out after esophageal cancer operation by jejunostomy.

In addition, after esophageal cancer surgery, in order to facilitate the healing of anastomotic stoma, gastric tube decompression is also needed. However, the dry and pain of the nasopharynx and the laryngeal muscles are directly caused by the indwelling stomach tube to severely contract, mucous nerve plexus is indirectly stimulated, the patients have reflexive symptoms of nausea, vomiting, chocking cough and the like, and suffocation can be caused in severe cases. Moreover, the stomach tube is deformed in the throat part to influence the reflective swallowing action and the respiratory function of the patient, so that sputum is accumulated in the throat part to aggravate the situation of dyspnea. There is a need for an improved jejunostomy tube of the prior art.
