Description

Double-cavity air bag sleeve for jejunostomy

Technical Field

The utility model belongs to the technical field of medical treatment auxiliary appliance, concretely relates to can avoid stomach tube to the stimulation of throat portion, the patient breathes more unobstructed, can control the speed of giving nutrition to reduce the stimulation of intubate to coincide mouthful repeatedly, do benefit to the recovered jejunostomy two-chamber gasbag sleeve pipe of patient.

Background

In the esophageal operation, a stomach tube negative pressure reduction mode is often needed to reduce the tension of an anastomotic stoma, and in addition, jejunostomy is also often needed. The patients after esophageal surgery have long hospitalization time, more side effects, frequent symptoms of respiratory failure, esophageal anastomotic fistula and the like, and higher mortality rate. Meanwhile, the stomach tube greatly influences the respiratory function and influences the growth of the anastomotic stoma. In the clinic, the stomach tube has a plurality of side effects, because the stomach tube needs to pass through the nasopharynx throat, and the muscle of the nasopharynx is the skeletal muscle, so, the use of current stomach tube has following shortcoming: 1. the stomach tube can stimulate the throat, which causes adverse physiological reactions of malignant vomiting and the like of patients; 2. when the stomach tube runs in the esophagus, the closing function of the pharyngeal esophageal muscle can be influenced, and the liquid in the tubular stomach flows back, so that the aspiration pneumonia is easily caused, and the recovery of a patient is influenced; 3. the stomach tube passes through the throat and can affect the respiratory function of a patient; 4. the stomach tube in the throat part can influence the action of the patient for physiologically swallowing sputum, so that the sputum is accumulated in the throat part, the breathing difficulty of the patient is aggravated, and the sputum excretion is influenced; 5. the insertion of the stomach tube can also aggravate the inflammation of the esophageal anastomotic stoma and stimulate the growth of scars, thereby causing the esophageal anastomotic stoma to be narrow, and the stomach tube runs through the pylorus, and also can increase the physiological reaction of gastrointestinal peristalsis and reduce the pressure of the pylorus.

In addition, in the open abdominal esophagy, the jejunostomy is frequently performed, and the nutrition therapy is given to the patient through the jejunostomy after the operation, so that the enteral nutrition can be given to the patient as early as possible after the operation, and the side effect of TPN (parenteral nutrition) is reduced. However, at present, a medical rubber tube with a common caliber is generally used in clinic to be matched with an injector to inject nutrient solution for treatment, so that the phenomenon that the caliber of the head end of the injector is not matched with the size of the jejunostomy tube exists, the speed of the nutrient solution entering the jejunum is difficult to control, and the performance of adapting to the physiological needs of patients is poor. There is a need for an improved jejunostomy tube of the prior art.
