Description

Nasogastric tube feeding system

The invention relates to a feeding system, especially a nasogastric tube feeding system.

According to the development of science and technology and the advancement of medical technology, there have been significant breakthroughs and evolutions in the discovery and treatment of diseases, which has relatively increased the survival rate of injured patients. Only when patients cannot eat on their own due to injury or aging, it is necessary Medical staff or family members are fed via a nasogastric tube feeder, that is, by means of intubation, the amount of residual food in the stomach and gastric acid detection, infusion of warm water to warm the stomach and intestines, infusion of fluid food (the food is stirred into liquid, It can also provide milk, nutrient solution, fruit juice, gravy, etc.) with the nutrition needed by patients and infusion of drugs to provide therapeutic effects.

The conventional nasogastric tube feeder includes: an empty feeding needle and a nasogastric tube. The empty feeding needle is connected to one end of the nasogastric tube, and the other end of the nasogastric tube is inserted into the stomach from the patient’s nasal cavity. When in use, the empty needle is used to detect the amount of residual food and gastric acid in the patient’s stomach, pull out the push-pull rod of the empty needle, pour an appropriate amount of warm water to the empty needle, and infuse the patient along the nasogastric tube Stomach, to warm the stomach and moisturize the intestines, then pour fluid food into the empty needles in batches to provide the patient with the nutrients needed, then pour the liquid medicine into the empty needles to provide the therapeutic effect, and finally pour an appropriate amount of warming Boil water until the empty needle is fed to prevent the liquid medicine from remaining on the empty needle and nasogastric tube.

However, in the conventional nasogastric tube feeder, when performing a filling operation, the operator needs to hold the empty needle for at least 12 to 15 minutes in his hand, which causes the operator’s hand soreness. In addition, warm water and fluid food are used. And when the liquid medicine is poured into the empty needle, it often leaks due to inaccurate filling, which causes inconvenience in use. Moreover, the temperature of warm water, fluid food and liquid medicine cannot be accurately controlled, and temperature is easy to occur. If it is too high or too low, there is indeed a need for improvement.

In view of the above-mentioned shortcomings of the conventional nasogastric tube feeding device, the present inventors developed the present invention based on the idea of thinking and creation, after many discussions, trial sample tests, and many modifications and improvements.
