Background

Intravenous infusion is a method of infusing a large amount of sterile liquid, electrolyte and medicine into the body from veins by utilizing the principles of atmospheric pressure and hydrostatic pressure. The injection site and the transfusion are different, and the injection can be classified into peripheral venous transfusion, central venous transfusion, high nutrient Transfusion (TPN), blood transfusion and the like. Intravenous infusion therapy is a highly specialized technique, and the treatment level covers parenteral infusion, nutrition support, medication and infusion. Intravenous infusion routes and infusion techniques are essential guarantees for Parenteral Nutrition (PN). Parenteral nutrition is the supply of nutritional elements required by a patient via the intravenous route, including calories (carbohydrates, fat emulsions), essential and non-essential amino acids, vitamins, electrolytes and trace elements. Suitable for people who cannot eat for a long time (more than 7 days) or cannot take daily required calories, proteins or other nutrients by the enteral route and for people who need nutritional support due to severe gastrointestinal dysfunction or intolerance to enteral feeding.

When the transfusion speed of a patient is too high, the circulating blood volume is increased rapidly, and the heart load is too heavy, so that acute pulmonary edema is easy to cause; the infusion of high-concentration and strong-irritation liquid medicine, particularly nutrient solution, can cause vein spasm to cause pain, and even can cause local vein infection to cause phlebitis due to chemical reaction of local vein walls; under the low temperature environment such as winter, the liquid of input normal atmospheric temperature is apt to make the patient with poor tolerability fear cold, shiver, even the low temperature state.
