Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a critical clinical liquid food feeding device. Background Art

[0002] Patients in intensive care have basically lost the ability to take care of themselves, but critically ill patients must have enough nutrition to supply their body's consumption, and often need to be fed using a feeder.

[0003] In the prior art, patients are usually fed at intervals, and medical staff or family members manually feed a certain amount of liquid food to the patient through a nasogastric tube or a gastric tube through a feeder. The feeder is usually in the form of an extrusion, but it is difficult to quantitatively deliver liquid food by extrusion, resulting in difficulty in controlling the amount of liquid food fed. Excessive liquid food can cause the patient to choke and cough, and it is difficult to control the speed of liquid food feeding by extrusion, which can easily cause discomfort to the patient; in addition, liquid food feeding for patients is generally carried out at fixed intervals, but there are differences in the digestive abilities of different patients. After a fixed interval, some patients may not have fully digested liquid food. At this time, if the patient is fed liquid food again, it is easy to cause too much liquid food in the patient's stomach, which will burden the patient's digestion, and the amount of liquid food feeding is difficult to match the patient's needs; in addition, liquid food feeding requires a certain amount of time, and the liquid food is exposed to the air for a long time, especially in the second half of feeding, the temperature of the liquid food decreases, which can easily cause discomfort to the patient. For this reason, we propose a critical clinical liquid food feeding device to solve the above problems. Summary of the invention
