Imbedding guiding device for nasointestinal feeding tube

Abstract

An imbedding guiding device for a nasointestinal feeding tube is specially designed for arranging a nasointestinal feeding tube in an operation when a tracheal catheter is used on a general anesthesia patient and is an assisting device for arranging the nasointestinal feeding tube. The imbedding guiding device for the nasointestinal feeding tube is composed of a push rod, a tracheal catheter guiding ring, nasointestinal feeding tube guiding rings and an observation channel. A hollow tube is selected as the push rod, the observation channel is formed in the center of the hollow tube, and a light source and a camera can be arranged. A diagonal plane is arranged at the front end of the push rod, the topmost end of the push rod is in a circular arc shape, a positioning label is arranged in the circular arc center, the two nasointestinal feeding tube guiding rings are arranged on one side face of the push rod, and the tracheal catheter guiding ring is arranged at the front part of the opposite side face of the push rod; the tracheal catheter guiding ring and the nasointestinal feeding tube guiding rings are in a C shape or a U shape and have certain elasticity.

Description

technical field [0001] The invention relates to a medical device, more specifically a nasojejunum nutrition tube insertion guide device. Background technique [0002] With the rapid development of modern medicine, it has become a consensus that enteral nutrition is used to support the treatment of patients with digestive tract tumors and other diseases after surgery. This kind of operation is due to the removal of many tissues and organs, reconstruction of the digestive system, etc., and the trauma is relatively large, resulting in the slow recovery of gastrointestinal function in patients after surgery, and even gastroparesis and difficulty in recovery of gastrointestinal function, which directly affect the postoperative recovery of patients. recover. Complications after esophageal and cardiac surgery require patients to fast for a long time. It is currently believed that intestinal mucosal atrophy and barrier function damage begin to occur after the body has fasted for m...

AI Technical Summary

Problems solved by technology

[0006] When using the method of placing a nasojejunal nutrition tube during the operation, since the patient under general anesthesia is in an unconscious state, it is impossible to ask the patient to complete swallowing and other actions to cooperate with the placement of the nasojejunum nutrition tube; The oropharynx and hypopharynx occupy a certain position to prevent the nasojejunal feeding tube from descending into the esophagus through this passage

Because there is a tracheal tube in the upper part of the hypopharynx, the nasal jejunal feeding tube returns to the oral cavity from the pharynx when it descends here. The tube cannot enter the esophagus, resulting in the failure of nasojejunal feeding tube intubation

Due to the blockage of the tracheal tube in the throat, it is difficult to insert the nasojejunum nutrition tube during the operation. The nasojejunum nutrition tube is easy to be coiled in the mouth, and the nurses cannot smoothly insert the nutrition tube into the esophagus. This can also be called blind insertion

The time of inserting the nutrition tube is too long, the accuracy rate is low, and there is no clear direction, which leads to a high incidence of wrong insertion of the gastric tube and nutrition tube. Repeated blind insertion leads to edema of the throat tissue and aggravates the difficulty of intubation; there are abundant cavernous venous tissues in the nasal cavity, If the blind insertion of the jejunal nutrition tube cannot be successfully performed once, repeated re-insertions may also easily cause nasal mucosal bleeding
