Problems solved by technology

[0002] After a person’s gastric injury or resection operation, he cannot eat normally, and food cannot pass through the stomach. The traditional method is to infuse the nutrient solution into the human body through the vein, but the intestinal flora imbalance will affect the function of the intestine due to the intravenous infusion. The need is to insert a nasal feeding tube into the intestine, but since the entire channel (nose to intestine) is about 1.4 meters long, such a long tube is inserted into the middle of the intestine with many grooves and ridges, and the 4mm tube is difficult to reach through blind insertion In the intestine, especially at the pylorus, the pylorus is in an S-curved shape, and it is difficult to operate; therefore, we propose a visual nasogastric tube and its application method

Abstract

The invention discloses a visible nasal gastrointestinal tube, which comprises a catheter and a display device, one end of the catheter is integrally connected with a threaded connector, one end of the threaded connector is connected with a guide wire handle in a threaded fit mode, the end, located in the threaded connector, of the guide wire handle is connected with a guide wire, a transmission connector is connected with a transmission cable, a flexible circuit board, a camera and a light source are installed in the end, away from the threaded connector, of the catheter, and the transmissionconnector is in signal connection with display equipment. The invention further discloses a using method of the visual nasal gastrointestinal tube. The using method comprises the steps of tube placement, normal saline soaking, intestinal tract penetration and nutrient solution conveying. The visible nasogastric tube and the using method thereof are more scientific and reasonable, the position ofthe tube can be seen through the camera installed at the front end of the catheter, operation is more convenient and faster, damage to the gastrointestinal tract of a patient can be well avoided, practicability is high, and popularization is facilitated.
