How enteral feeding pump drug delivery pumps work?

August 16,2023

A enteral feeding pump is a device that can deliver liquid nutrients to the human blood circulation.


Its working principle can be divided into the following steps:

1. Nutrient preparation: The nutrients (such as fat milk, amino acid solution, etc.) are prepared in advance and configured to the concentration suitable for infusion.

2. Infusion line connection: Connect the infusion line to the patient's venous passage or central venous catheter, and ensure that there is no leakage at the connection.

3. Pump control: Set the infusion speed and infusion time of the nutrient pump according to the doctor's instructions to ensure that the patient receives the appropriate nutrient infusion.

4. Pump work: Nutrition pump through the internal mechanical device, the nutrients are pumped out of the storage container, and pushed to the infusion line.

5. Infusion monitoring: The nutrient pump is usually equipped with an infusion monitoring
system, which can monitor the infusion speed and total infusion in real time, as well as an alarm function to remind the operator in time when there is an abnormal situation. In general, the nutrient pump works by mechanically pumping pre-prepared liquid nutrients out of the storage container and pushing them into the patient's blood circulation to maintain the patient's nutritional status. In this way, the speed and amount of infusion can be accurately controlled to ensure that the patient receives the appropriate nutrient supply.


Enteral feeding pumps offer several benefits:

Precise Nutrition: Enteral feeding pumps provide accurate and consistent delivery of nutrition, ensuring that patients receive the appropriate amount of nutrients and calories.

Better Tolerance: By delivering nutrients directly into the gastrointestinal tract, patients may experience better tolerance and reduced risk of complications compared to parenteral nutrition.

Flexibility: Enteral feeding pumps allow for controlled feeding schedules, enabling patients to receive nutrition throughout the day and night.

Reduced Burden: Enteral feeding pumps help reduce the manual effort required for administering nutrition, which can be especially important for caregivers and medical staff.
