Background

Nasal feeding is a way of manually placing a catheter into the stomach or duodenum through the nasal cavity and filling liquid food, water and medicines into the catheter when a patient cannot take food through the mouth due to various reasons so as to ensure the nutritional requirements of the patient and achieve the purpose of treatment. At present, patients in hospitals, nursing centers, rehabilitation centers and family sickbeds have a lot of patients with dysphagia, gastroesophageal surgery, oral surgery, coma and the like, and the nasal feeding needs to be carried out by using a needle-cylinder-shaped syringe. The mode of manually pressurizing and injecting after the injector pumps fluid and connecting the gastric tube is mostly adopted clinically. However, the existing syringe injectors have the following disadvantages: 1. the syringe injector has small volume, is difficult to carry out large-flow nasal feeding, needs two hands to operate after the syringe is enlarged, and is inconvenient to use; 2. when thick fluid is fed, the common injector is difficult to inject; 3. when the syringe is used for nasal feeding of drugs or moisture, the syringe is easily confused with an intravenous injection syringe, so that serious adverse effects and even death are caused.
