Disposable gastrointestinal nutrition infusion pipeline is mainly used in the following scenarios: 1. clinical departments of the hospital Intensive care unit (ICU): patients in ICU are critically ill, often accompanied by unconsciousness, dysphagia or gastrointestinal dysfunction, and unable to eat by mouth. Gastrointestinal nutrition infusion pipeline can provide enteral nutrition support for patients through nasogastric tube, nasointestinal tube, percutaneous gastrostomy, enterostomy and other ways, to ensure that patients take enough nutrients such as protein, calories, vitamins and minerals, maintain body metabolism and immune function, and promote treatment. General ward: for some patients with normal gastrointestinal function but unable to eat by mouth due to surgery, trauma, disease, etc., such as oral and maxillofacial surgery, esophageal surgery, comatose patients, severe burn patients, etc., gastrointestinal nutrition infusion pipeline is an important nutrition supply channel. The direct infusion of nutrient solution into the gastrointestinal tract can avoid the complications caused by long-term intravenous nutrition, such as infection and thrombosis, and help maintain the normal physiological function and structure of the gastrointestinal tract, reducing the risk of intestinal bacterial translocation and infection. Gastroenterology: some patients with digestive system diseases, such as Crohn's disease, ulcerative colitis, and short bowel syndrome, may have intestinal malabsorption or digestive dysfunction. According to the specific condition of the patient, the gastrointestinal nutrition infusion pipeline can correctly deliver the nutrient solution with special formula to the specific part of the intestinal tract for enteral nutrition support and treatment, which is helpful to improve the nutritional status of the patient and promote the repair of intestinal mucosa and disease treatment. 2. medical institutions: in medical institutions, some patients with swallowing dysfunction or physical weakness caused by stroke, brain injury, etc. need long-term nutritional support to promote physical recovery. The gastrointestinal nutrition infusion pipeline can conveniently provide these patients with nutrient rich and easily digested nutrient solution, help patients maintain good nutritional status and improve the therapeutic effect. 3. home care: some patients with stable disease but still need long-term gastrointestinal nutrition support can use gastrointestinal nutrition infusion pipeline for self-care at home under the guidance of doctors. This can not only improve the quality of life of patients, reduce hospitalization time and medical expenses, but also allow patients to receive treatment in a familiar family environment, which is conducive to the psychological treatment of patients. For example, some patients with advanced cancer, nervous system diseases and other causes of eating difficulties can maintain physical function and improve the quality of life to a certain extent by nutritional supplement through gastrointestinal nutrition infusion pipeline at home.
