Description

Multifunctional nasal-intestinal nutrition tube capable of positioning body surface Technical Field The utility model relates to the field of medical instruments, in particular to a multifunctional nasal-intestinal nutrition tube capable of positioning a body surface. Background Nutrition is important in comprehensive treatment of tumors, so that the curative effect of radiotherapy and chemotherapy is affected, and the nutrition is closely related to prognosis of tumor patients. Digestive tract tumors often cause gastric retention due to gastric dysfunction, thereby affecting the conventional intake of nutrition, and nasojejunal nutrition is the most stable and safe and effective nutrition intake mode. There are two common methods for placing the jejunal nutrient canal, namely, percutaneous endoscopic gastrostomy jejunal canal placement and nasal jejunal canal placement. However, either mode is extremely unsuitable for oncology patients, particularly moderately severe dystrophy patients. The method has the advantages that the method has high requirements on patients, anesthesia indexes are high, the cost is high, the method needs interventional department evaluation, the defects of large radiation and the like exist in the operation, multi-disciplinary cooperation is needed, the flow is complicated, the requirements on the general state of the patients are high, the cost is high, the number of days in hospitalization is increased, and the like. Some patients with severe tumor and contraindications in surgical anesthesia lose the opportunity for placing nasal jejunum tube because of the inability to anesthetize. In addition, the clinical demand of simple and effective nasal jejunal tube implantation is large, except for the needs of tumor patients, the patients with leather stomach, neurology cerebral palsy and the like in gastroenterology all need jejunum nutrition to meet the energy demands of organisms. Therefore, it is necessary to design a novel nutrition tube with body surface positioning function, which can be finished by bare hands at the bedside, has good convenience and popularization value.
