Multifunctional nasal feeding tube and nasal feeding system

Abstract

The invention provides a multifunctional nasal feeding tube and a nasal feeding system. The multifunctional nasal feeding tube is characterized in that a tube body of the nasal feeding tube is internally provided with a non-return valve; an airbag is arranged at the outer side of the tube body of the nasal feeding tube; the airbag is connected with a pressurizing airbag through an air guiding tube. The non-return valve can be used for preventing nutrient solution in the nasal feeding tube from reflowing; the airbag at the outer side of the tube body of the nasal feeding tube is inserted in the position of stomachus cardiacus; after the inflation of the pressurizing airbag, the situation that gastric contents at the outer side of the nasal feeding tube are sucked into a lung by mistake due to reflow can be effectively prevented. According to the multifunctional nasal feeding tube and the nasal feeding system, aspiration complications caused by enteral nutrition support therapy through nasal feeding can be prevented specifically; the lung infection, severe pneumonia, even asphyxia caused by aspiration progress are effectively reduced, and the death rate is lowered. The multifunctional nasal feeding tube and the nasal feeding system can be widely suitable for popularization and application of clinical enteral nutrition support therapy. Moreover, the nasal feeding tube is further provided with an injector joint and a drug administration joint, so that the drug administration operation is conveniently performed on a patient who cannot swallow drugs independently. A feeding material supply system is arranged in the nasal feeding system, nutrients can be continuously fed to the patient after the connection with the nasal feeding tube, and the feeding efficiency is improved.

Description

technical field [0001] The invention belongs to the field of medical appliances, in particular to a multifunctional nasal feeding tube and a nasal feeding system. Background technique [0002] Enteral nutrition support refers to a treatment method in which a nasal feeding tube is inserted into the gastrointestinal tract through one side of the nasal cavity, oral cavity, gastrointestinal stoma, etc. for artificial feeding to ensure that the patient can absorb enough nutrients such as protein and calories. Nutrient factors input through the nasogastric tube enter the liver through the portal vein, which can promote the recovery of intestinal function, improve the nutritional status of the body, and effectively shorten the course of treatment for the disease. [0003] Enteral nutrition support via nasogastric tube is convenient and effective, and has been recognized by clinicians all over the world. However, problems such as hyperglycemia and stress ulcers may occur at the same...
