What are the necessary components of general infusion pumps?

General infusion pumps are vital pieces of medical equipment used to deliver fluids, medications, or nutrients to patients in a controlled manner. The correct components of these pumps include a power source, tubing, and sensors.

The power source is essential for operating the pump, enabling it to function effectively whether it is plugged into an electrical outlet or using battery power for portability. Tubing is critical as it connects the pump to the patient and facilitates the flow of the delivered substances into the body. Sensors are crucial for monitoring the flow rates and ensuring that the infusion is occurring accurately according to the preset parameters, thereby enhancing patient safety.

In contrast, while other options may include components that are relevant to different types of medical devices, they do not accurately reflect the necessary components of general infusion pumps. Components like suction units or inhalation devices are related to different medical devices and serve other functions that do not pertain to infusion delivery.
