Fiber Optic Conducting Wire: When the wire connected with power, the entire wire can be presented as strong, weak, and flash light modes, while flash mode is recommended during insert of the catheter. The wire plays a role in shaping the catheter, which helps the catheter to slide into the esophagus through the nose and mouth and then into the stomach; The light source can be found as red light spots through the skin, which can reflect the accurate position of the catheter in real time, preventing the catheter from entering the airway by mistake. When the catheter body enters the stomach, a red light spot appears on the left upper abdominal wall, and the traditional tedious method of confirming the position of the catheter is no longer needed. Three Cavity Tube Body: Cavity for water balloon - Primary Cavity - Side Cavity Separative Cavity for filling balloon with water or other solution. Can effectively block gastroesophageal reflux and play an internal fixation role. Primary Cavity: For gastrointestinal decompression, enteral nutrition and irrigation. Side (auxiliary) Cavity: For monitoring of intragastric load and enteral nutrition degree, also for adjusting the rate of nutrition giving. The unique dual-cavity structure of two cavities can effectively avoid adherence, reduce gastric mucosal irritation and damage, and prevent catheter blockage. Water Balloon: After the nasogastric tube is inserted in, fill the balloon with 5ml of Normal Saline. The tip designed with a fillable balloon plays a fixation roll once is the catheter is set. The subjective feeling of patients are significantly improved and patients are easily tolerated to this treatment. Finally, the accidental catheter extubation can be reduced or eliminated. The fixation of balloon can effectively prevent the occurrence of aspiration pneumonia due to gastric reflux through the esophagus and reduce the incidence of medical errors; The fixation of the balloon allows the catheter to be suspended in the center of the gastric body to reduce adherence gastric mucosal damage.
