Automatic feeding device

The present invention relates to a feeding device, and more particularly to an automatic feeding device suitable for feeding a patient having a nasogastric tube.

With the advancement of technology and the advancement of medical technology, the survival rate of injured patients has been relatively improved. However, patients cannot eat through the mouth because of coma, neck and neck disease, difficulty in swallowing, severe burns, end-stage cancer, or surgery. When the gastrointestinal function of the patient is normal, the nasogastric tube can be fed by the medical staff or the family to provide the calories and nutrients needed by the patient.

Nasogastric tube feeding is a method of intubation, which treats the diet into a fluid state and flows into the stomach through the nasal cavity. The way of feeding the nasogastric tube can be divided into empty needle feeding, continuous feeding and intermittent feeding. Three kinds of which are more common with empty needle feeding. Before operation, the doctor inserts the nasogastric tube into the stomach through the nasal cavity, and then the caregiver or family member and the caregiver are connected to the mouth of the other end of the nasogastric tube. The needle allows the food to enter the stomach by feeding an empty needle through the nasogastric tube to achieve the purpose of eating.

During the feeding process, when the patient has nausea, vomiting, diarrhea, sweating, cramps and rapid heartbeat, the feeding action should be stopped immediately and the medical staff should be notified to handle the treatment. Therefore, during the feeding process of the nasogastric tube, care is taken. Not only do you have to take a feeding action, you must also keep an eye on whether the patient has any discomfort to avoid accidents.

In addition, since the nasogastric tube should be fed with a small amount of no more than 300cc each time, it is necessary to feed about 5 to 8 times a day, and the feeding speed should not be too fast, so as to avoid Patient vomiting Spit or discomfort, after washing, you need to wash the tube with 30~50cc of boiling water. The tedious work of feeding and cleaning many times every day makes the caregiver exhausted every day, which is not only extremely inconvenient, but also a kind of care for the caregiver. The burden, so the customary nasogastric tube feeding design does need to be improved.
