Tubing – It transfers insulin from the reservoir to the infusion set.
Infusion set – It is attached or connected to the skin; the tube pierces the skin to supply insulin to the body.
Using the Device
Using a pump for insulin therapy requires some training. Your doctor can guide you to perform each step.
The device maintenance

Most pumps can hold insulin for up to five days. The device sounds a warning when the insulin stock is low. You can then fill it once the insulin is at room temperature. Using it directly after removing it from refrigerator may cause air bubbles to get inside the pump.
