Description
Technical field
The utility model is related to technical field of medical instruments, and in particular to a kind of multi-cavity visible nasointestinal tube.
Background technology
At present, critical patient early stage carries out enteral nutrition and had great importance, but stress in the case of, in light more than stomach
Paralysed state and there is gastric retention, so can undoubtedly increase gastric content from backwards flowing causes to inhale by mistake, and conventional ICU medicine is as calm
The application of agent, analgestic, vasoactive drug etc. can cause WeiDongLi Capsule to reduce, and further increase air draught danger by mistake.Intestines built-in pipe is
By the pipe end indwelling of nasointestinal tube or other particular tubes in duodenum or jejunum, it can reduce reflux, inhale equivalent risk by mistake.Separately exist
In some diseases as severe pancreatitis need carry out gastrointestinal decompression, to alleviate stimulation of the gastric juice to pancreas.
Rational EN support has extremely important meaning, and especially enteral nutrition compares stomach in terms of nutritional support
Parenteral nutrition more meets physiological status, and intestinal absorption nutrient solution is most fast, has more preferable metabolic effect, nutritive validity and reduces and inhales by mistake
With backflow.Enteral nutrition includes tube feeding built in stomach, tube feeding built in nose duodenum and three kinds of tube feeding built in nose jejunum
Mode, feeds if patient has in gastric emptying disorder or unsuitable stomach, needs to perform tube feeding built in nose duodenum or nose is empty
Intestines put tube feeding.
It is of the present utility model inventor has found that the method for clinically nose duodenum or jejunum built-in pipe at present
Mainly have following several：1st, it is blind to regard method：Main application spiral shape nasointestinal tube is carried out, and rule of thumb judges whether to have reached after intubation
Correct position, puts the pipe arrival specified location time longer, in addition it is also necessary to verified by x-ray, confirm and reach again to enter later using this method
It is cumbersome in row note nutrient solution, operation, and success rate is relatively low；2nd, gastroscope guides underlying pipe：Method is regarded this method avoid blind
Middle blindmate puts the blindness of pipe, can improve and put pipe speed, and success rate is up to more than 95%, but there is the possibility of cross-infection
Property, and should not generally be moved for Critical Ill Patient, practical operation gets up highly difficult, and it is higher to put pipe cost；3rd, under X-ray examination
Put pipe：This method avoid the blindness that blindmate puts pipe, and avoid within upper digestive tract partial obstruction or other reasonses cause
The intransitable defect of mirror, it is higher to put pipe success rate, but this method indwelling catheter time is long, and doctor and patient is when being both needed to receive long
Between x-ray radiation；4th, the underlying pipe of operation：Stoma of jejunum (PRJ) is equal under jejunostomy (PEJ), percutaneous image under Percutaneous endoscopic
Need special apparatus and need to be grasped skilled endoscopic technic technology, and the relatively other methods of expense will height；5th, ultrasound is drawn
Lead underlying pipe：Need the B ultrasound doctor operation of specialty, it is desirable to higher, and and it is indirect visual, stomach and intestine hollow organ gas compared with
It is many, influence its effect.Therefore, preceding method more or less all has some defects or deficiency.
