Background technique

Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the vein using the principles of atmospheric pressure and hydrostatic pressure. Injecting large amounts of fluids, electrolytes, or blood into a vein is called intravenous infusion. Due to the different injection sites and infusions, it can be divided into peripheral venous infusion, central venous infusion, high nutrition infusion and blood transfusion. Intravenous infusion therapy is a highly specialized technology, and its treatment level covers parenteral infusion, nutritional support, medication and infusion therapy.

Intravenous infusion takes a long time, and clinical nursing problems such as infusion leakage and needle removal often occur in the intravenous infusion in the hospital, especially children patients, because they are not easy to control, restless and crying, needle prolapse or infusion leakage often occurs.
