Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and particularly relates to a liquid food feeding auxiliary device. Background Art

[0002] In the field of medical care, for patients who are unable to eat normally through the mouth, nasal feeding with liquid food is an important way of nutritional support. However, at present, there are some problems in the process of using a nasal feeding tube for liquid food feeding, which bring great troubles to medical staff and patients' families. On the one hand, there are usually differences in size and shape between the interface of the nasal feeding tube and the needle of the syringe, resulting in an insecure connection between the two. During the process of injecting liquid food, due to the need to apply a certain pressure, if the connection is not stable, it is easy to cause the disconnection of the joint of the nasal feeding tube. Once disconnected, it will not only affect the process of liquid food feeding, but also may bring serious consequences to the patient. For example, the leakage of liquid food into the surrounding environment may cause infection; if the disconnected part enters the patient's respiratory tract, it may also lead to dangerous situations such as asphyxia. On the other hand, the syringe often has difficulty in injecting after being used for a few days because the tiny particles in the liquid food may adhere to the inner wall of the syringe, further increasing the difficulty of injection. Moreover, for slightly thicker liquid foods, such as nutritional pastes added with vegetable puree, meat puree, etc., the existing syringes are even more difficult to inject. To sum up, there are problems such as difficult injection with a syringe and mismatch between the interface of the nasal feeding tube and the nipple of the syringe in the current nasal feeding tube liquid food feeding method. Therefore, the present invention provides a liquid food feeding auxiliary device to solve the above technical problems. Summary of the Invention
