Description

Nose intestines tube

Technical Field

The utility model relates to the technical field of medical appliances, especially, relate to a nose intestines tube.

Background

The enteral nutrition system is a nutrition supply mode adopted when the gastrointestinal tract function of a patient is basically normal and the patient cannot or does not want to take food orally or the oral intake cannot meet the nutritional requirement of the organism. The importance of enteral nutrition in gastrointestinal surgery is well known for a long time, the requirement for nutritional support does not only stay in maintaining the nitrogen balance of a group and keeping the lean body mass of a patient, but also needs to maintain the metabolism of cells and the structure and function of tissue and organs so as to regulate and control the functions of immunity, endocrine and the like and repair tissues and promote the recovery of the patient, and the clinical nutritional support participates in or becomes a main treatment method, and some of the enteral nutrition also has pharmacological action. Clinical application shows that the Chinese medicinal composition has enteral nutrition effect, and is an important treatment measure for intestinal fistula, short bowel syndrome, intestinal inflammatory diseases and the like, and is also an essential treatment measure for severe acute pancreatitis, organ transplantation, tumors and serious patients. The nasointestinal tube is widely applied to gastrointestinal surgery.

Currently, there are two main types of non-operative methods for placing nasointestinal tubes clinically: firstly, under the assistance of endoscope, under visual state, adopt the guide wire, send into duodenum to the nose intestines pipe. The method has the advantages that the guide steel wire is easy to damage the intestinal mucosa, and the depth of the guide steel wire penetrating into the tube is not clear. In addition, an endoscope is also needed, the workload of medical staff is increased, and the medical cost is increased. Secondly, a blind insertion method is adopted, and the method is mainly carried out by using a spiral nasointestinal tube. Insert the guide steel wire in the human nose intestines, make the nose intestines tube head of screw-tupe straighten, then insert the pipeline slowly from the nasal cavity, order the patient to do the swallowing action when inserting to the throat, the pipeline of being convenient for advances people's esophagus smoothly, withdraw from the guide steel wire when inserting to mark length, be fixed in the ear below that hangs down in the nasal cavity outer pipeline with the adhesive tape, make the pipeline keep natural bending, lax state. The material has special spiral memory performance, and its far end can restore its spiral shape, and after 8-12 hr in stomach, the nasointestinal tube can automatically pass through pylorus and enter human duodenum and jejunum under the action of gastric peristalsis. After 24h, X-ray radiography is carried out to confirm that the front end of the nasointestinal tube reaches the upper section of the jejunum, and the nose-intestinal tube is fixed below the nostrils and on the ears by adhesive tapes to prevent slippage. The application of the method needs to pass X-ray verification, has low efficiency, needs to additionally move patients, increases the working strength and improves the medical cost. The traditional nasointestinal tube guide steel wire channel and the injection channel are one channel, so that the use is inconvenient, and meanwhile, the infection risk is increased. In addition, the adhesive plaster is fixed on the ears, so that the patient is easy to fall off in the moving and carrying processes. When the adhesive tape is torn off, certain pain is brought to the patient.
