The drip rate during infusion can change on its own for different reasons. According to clinical practice, the following reasons have been found: (1) the drip rate was not fast at that time because the beveled surface of the needle was attached to the blood vessel wall at the beginning of the puncture, and the drip rate was not fast at that time, and the beveled surface of the needle was moved away from the blood vessel wall due to the change of the patient's body position in the infusion, and the result was faster on its own. (2) At present, the use of disposable infusion sets often results in the loss of control of the drip rate regulator. In general, according to the physical and chemical properties of drugs and therapeutic requirements to regulate the drip rate, input to the blood vessel stimulation of strong drugs should be appropriately slowed down the drip rate, in order to maintain the drip rate that is suitable for therapeutic requirements and to minimize the damage to the blood vessel stimulation of the drug, so that the patient does not affect the treatment of the situation and the feeling of relative comfort in the infusion. The vast majority of patients want to finish the infusion as soon as possible, especially near the meal or need to urinate and defecate when their mood is more urgent, at this time the patient is often on their own or ask the staff to speed up the drip rate, in order to avoid accidents, the staff need to explain to the patient and his family to speed up the drip rate will make the circulating blood volume in a short period of time increased dramatically, the burden on the heart and lungs increased, which can easily lead to cardiac failure and pulmonary edema, and so on, in order to achieve the purpose of the acceptance of the drip rate.
Replacement of fluids such as liquid bottles added to other drugs, its pressure and atmospheric pressure close to or greater than atmospheric pressure, should be the first bottle mouth upward, inserted into the infusion set, to wait a moment to expel air before hanging upside down in the infusion plus. This can avoid liquid outflow from the ventilation tube to reduce the amount of drug therapy and affect the treatment. Mastery of the replacement of liquid skills, can avoid the waste of drugs and prevent the dropper liquid level is lowered or empty so that the air into the vein, to the patient caused by the hidden danger of air embolism.
Experience has shown that the best time to remove the needle is when the liquid in the dropper has finished dripping and the drop in the tubing has slowed or stopped.

Traditional method of needle extraction With a cotton swab to press the eye of the needle to pull out the needle, the shortcomings of this method of pulling out the needle are: (1) it will make the two sides of the tip of the needle on the blood vessel wall to produce cutting force, blood vessel damage can release pain factor; (2) the endothelial damage, platelet aggregation easy to form thrombus, the emergence of hematoma, and is not conducive to the next puncture.
