Abstract
The utility model relates to an anti-blockage nasal jejunum nutrient canal which comprises a nutrient canal body. A water delivery branch is arranged at the rear end of the nutrient canal body, the nutrient canal body is sleeved in an outer sleeve, a data line for image transmission is further sleeved in the outer sleeve, a camera and a lighting device are arranged at the front end of the data line, and a data output port is arranged at the rear end of the data line. The water delivery branch can be a Y-shaped branch arranged on the nutrient canal body and can further comprises a three-way valve arranged on the nutrient canal body and a water delivery pipe connected onto the three-way valve. Due to the fact that the anti-blockage nasal jejunum nutrient canal is provided with the water delivery branch adopting the structure, when drugs, foods and nutrient solution gradually accumulate along the wall and block the canal cavity, water cannot be filled through a nutrient substance filling canal opening but is directly filled through the water delivery branch, the nutrient solution can be timely diluted, blockage can be prevented, and operation steps are decreased.
Description
Technical field
This utility model relates to a kind of the treatment and uses feeding tube, especially a kind of per nasal jejunal nutrient canal.
Background technology
The nutrition of patient's body that can not oral feeding water is required to be given entirely by vein or enteral.And intravenous nutrition expense costliness, and can not prolonged application.Through the nutrition of jejunum fistulation, though economical, convenient, the patient is reluctant to undergo surgery mostly.Keep somewhere duodenal feeding tube and both had easy, safe, effective, economic advantage, having again to perform an operation places the nutrition of jejunum fistulation brings painful and pressure to the patient characteristics.Therefore, adopt enteral nutrition is the clinical basic principle that should follow as far as possible.But, because luminal stenosis, and nutritional solution is sticky, concentration is high, causes the attached wall of medicine, food and nutritional solution to be hoarded gradually, stops up tube chamber easily, food goes mouldy after hoarding for a long time easily, corrupt food causes antibacterial or fungal enteritis.After the nutritive canal obstruction took place, existing technology generally was all to give eliminating cold for resuscitation water flushing tube chamber before and after injecting nutritional solution at every turn, stops up but still tube chamber takes place often, need insert jejunal nutrient canal again, increases the patient suffering, and it is negative to increase the weight of economy.When inserting nutritive canal, generally adopt blind insert method in addition, rule of thumb judge whether after the intubate to have arrived correct position, very bother in the operation, and medical personnel's experience is had relatively high expectations.
The utility model content
The technical problems to be solved in the utility model provides a kind of per nasal jejunal nutrient canal that can prevent that nutritional solution from stopping up.
For solving the problems of the technologies described above, blockage resisting per nasal jejunal nutrient canal of the present utility model, comprise nutritive canal, the nutritive canal rear end is provided with a water delivery branch road, nutritive canal is enclosed within the trocar sheath, also overlap the data wire that is useful on images in the trocar sheath, the data wire front end is provided with photographic head and illuminator, and the data wire rear end is provided with data output.
Described water delivery branch road can be the Y type branch road that arranges in nutritive canal.
Described water delivery branch road can also be included in the three-way valve that arranges in the nutritive canal and the water-supply-pipe that is connected on the three-way valve.
After adopting such structure, owing to be provided with the water delivery branch road, when the attached wall of medicine, food and nutritional solution is hoarded the obstruction tube chamber gradually, can be from injecting the mouth of pipe water filling of nutrient substance, but directly carry out water filling from the water delivery branch road, can in time dilute nutritional solution, prevent from stopping up, reduce operating procedure.At the nutritive canal front end photographic head and illuminator are set and can observe the nutritive canal pipe and arrive particular location in patient's body, make nutritive canal on position accurately and the insertion time short, alleviated the misery that intubate causes patient.
