Description

Disposable nasal feeding gastrointestinal nutrition tube device

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of medical instruments, in particular to a disposable nasal feeding gastrointestinal nutrition tube device.

[ background of the utility model ]

The disposable nasal feeding gastrointestinal nutrition tube device can be inserted into a nutrition tube for a plurality of critically ill patients with different disease conditions and different postoperative states, so as to supply nutrients required for survival for the patients. But it is difficult to insert a feeding tube clinically, especially the esophagus. After major surgery of gastroesophageal cancer, the structure of the normal digestive tract of a patient is reconstructed, and the patient is implanted into a nasal feeding gastrointestinal nutrition tube in an unconscious state during the surgery, which brings much trouble to clinical work. Before a doctor puts a nasal feeding gastrointestinal nutrition tube into a patient in an operation, the outer wall of the nutrition tube needs to be coated with paraffin to lubricate the nutrition tube, a guide wire is arranged in the nutrition tube, the nutrition tube is sent into the nutrition tube through a nasal cavity, the nutrition tube can enter an esophagus from a pharynx and then is sent into a digestive tract (a tubular stomach) reconstructed in the operation, and then the head of the nutrition tube needs to be sent into the position below a stomach pyloric canal. The difficulty of placing the nutrition tube after reconstruction of the digestive tract of the esophagus and the stomach is increased due to unconscious coordination of patients in the operation, reconstruction of the digestive tract and the like, and in addition, lubricating oil can only be coated on the outer wall of the nutrition tube before the nutrition tube is inserted, and a few lubricating oil coated on the outer wall of the nutrition tube is remained after the lubricating oil passes through the nasopharynx. In the process of continuously feeding the nutrient canal into the digestive tract, the nutrient canal is pushed under the condition that the outer wall of the nutrient canal is basically not lubricated enough, so that friction between the nutrient canal and the digestive tract is caused, the nutrient canal is folded or pushed unsmoothly in the digestive tract, and the like. Sometimes, because the feeding of the nutrient canal is not smooth due to folding, the reconstructed digestive tract wall is propped open after receiving the force from the guide wire carried in the folded nutrient canal, and the tension is given to the reconstructed digestive tract wall, thereby increasing the incidence rate of the leakage of the digestive tract after the reconstructed digestive tract operation. Whether the feeding of the nutrition tube is smooth in the operation also directly influences the operation time. The head of the nutrition tube is sent to the position below the stomach pyloric canal by the operation incision of the abdomen, an operator grasps the head of the nutrition tube, the doctor who puts in the nutrition tube pulls out the guide wire after straightening the nutrition tube, and stitches the abdominal wall incision after fixing the part outside the nutrition tube body; in the process of propelling the feeding tube, the smooth propelling of the head part plays a key role in the process of feeding the feeding tube, and if the head part of the feeding tube is normally propelled in the reconstructed digestive tract, the feeding tube can be smoothly fed into the part below the gastric pyloric tube. At present, no nutrition tube which can be continuously supplied with paraffin oil to lubricate the outer wall of the head of the nutrition tube after being delivered into the alimentary canal is clinically available.

Patent document CN212347198U, bulletin day 2021.01.05 discloses a three chamber intestines and stomach nutrition pipe, including the heating cavity, the inside vertical fixed hot plate of having placed of heating cavity, the hot plate is divided into intestines and stomach nutrition chamber, intestines and stomach decompression chamber, medicine injection chamber with the inside of heating cavity. The advantages are that: the pressure reduction, the nutrition supply and the medication can be realized by only one gastrointestinal nutrition tube, so that the comfort of a patient is improved, and the opening and closing of the nutrition tube can be controlled more conveniently. However, the feeding tube cannot supply lubricant to the feeding tube body during the insertion process, and the reconstructed digestive tract may leak after the operation.

In summary, there is a need for a disposable nasogastric and intestinal nutrition tube device that not only can provide nutrition to a patient, but also can supply lubricant to the tube body of the nutrition tube during the insertion process, thereby accelerating the surgical procedure.
