Description
Technical Field
The utility model belongs to the technical field of medical instrument, a device for intestinal juice feedback is related to.
Background
When abdominal cavity infection is caused by intestinal fistula due to trauma, primary operation and other reasons of a patient, intestinal tracts of the patient cannot be subjected to enteroanastomosis for the first time, generally, an ostomy bag or a drainage bag is adopted to collect intestinal juice close to the heart end, and the intestinal juice is poured out after reaching a certain amount, and then is connected into a new ostomy bag or a new drainage bag again for repeated operation. Because the hospitalization period of the intestinal fistula patient is long, a large amount of digestive juice of the organism can be lost due to repeated pouring of the intestinal juice, serious malnutrition and water electrolyte disturbance are caused, and the recovery of the patient is not facilitated.
At present, a part of hospitals begin to adopt a simple intestinal fluid reinfusion method to try to improve the adverse effect caused by digestive juice loss, namely, an ostomy bag or a drainage bag is used for collecting near-heart-end intestinal fluid, then sterile gauze is used for simple filtration or no filtration, the intestinal fluid is poured into an infusion bag, and a far-end intestinal tube is reinfused. The processes of repeated collection, filtration, feedback and the like can increase the burden of medical personnel, the process is complicated, the cost is high, and simple, convenient and quick integral intestinal juice feedback cannot be realized. For example, chinese patent publication No. CN205569412U discloses a closed intestinal fluid reinfusion system, which comprises a closed ostomy bag, a filter box and a reinfusion tube. The device has the following defects that each layer of the filtering membrane consists of gauze, the bearing capacity of the gauze is limited, the gauze is easy to deform, and when the viscosity of intestinal fluid is higher, the gauze is easy to press down to form a depression. Meanwhile, when one layer of filtering membrane is blocked, the other filtering membranes can not filter. The top-down and series-connected multi-layer filtering methods have poor filtering effect and filtering speed. The whole operation process is relatively complicated, the cost is relatively high, and the practicability is not good enough.
In severe intestinal diseases such as intestinal fistula, intestinal resection and enterostomy cannot be performed in one stage, and temporary enterostomy is a common surgical mode, but in some cases, abdominal cavity and intestinal canal are seriously adhered due to the diseases, intestinal canal edema cannot free small intestines with enough length for abdominal wall stoma, or even after the abdominal wall stoma is performed by a reluctant force, the intestinal canal is broken and retracted into the abdominal cavity due to the serious intestinal canal edema and the fragile wall of the intestinal canal at the suture part. Therefore, for patients who cannot perform an enterostomy to the abdominal wall, an additional intestinal fluid return route is required.
