Description
Technical field
The invention belongs to enteral nutritions to supply field, and in particular to a kind of intestinal nutrient solution offer device of twin flue.
Background technique
Enteral nutrition (enteral nutrition, EN) is that the nutriment and other that metabolism needs are provided through gastrointestinal tract
The nutritional support mode of various nutrients.Intestines problem patient, can be because of function of intestinal canal disorder or lesion tissue under morbid state
Situations such as cause digestion power to decline, to occur normally feeding or the case where hypoalimentation, enteron aisle should be taken to seek at this time
Supply mean is supported, nutrient solution is directly fed for the enteron aisle of patient, avoids patient from the case where subalimentation occur, guarantee the body of patient
Body situation.
Existing enteral nutrition supplies technology, generally carries out the placement of stoma using stomach fistulization to patient, and will make
The infusion end of fistula is retained in outside patient body by abdomen opening, so set, the infusion of external nutrient solution injection stoma
The enteron aisle for holding and flowing into patient carries out the supply of enteral nutrition in which can be convenient.
But the problem of above-mentioned prior art still has is that the stoma being retained in outside patient body needs to clean and tie up often
Shield, and be easy to impact the daily life of patient, while the abdomen fistulization wound of stomach fistulization is also required to often nurse, and its
The case where skin of surrounding is easy to appear inflammation and sepage, causes secondary injury to patient.
Summary of the invention
In order to overcome the above technical defects, the intestinal nutrient solution that the present invention provides a kind of twin flue provides device, is not necessarily to
The body surface of patient manufactures wound, avoids wound inflammation and the sepage secondary injury caused by patient, while improving enteron aisle battalion
The efficiency of supply and the nutrient absorption degree of enteron aisle are supported, and prevents intestinal juice accumulation in patient's enteron aisle from damaging to enteron aisle.
To solve the above-mentioned problems, the present invention is achieved by following technical scheme:
A kind of intestinal nutrient solution offer device of twin flue, including liquid injection seat, the first catheter connecting with liquid injection seat, takes out
Liquid seat and the second catheter being connect with drawing liquid seat；
