The common use of disposable intravenous needle
The disposable intravenous needle is a medical method in which a liquid substance such as blood, a liquid medicine, or a nutrient solution is directly injected into a vein. Intravenous injection can be divided into transient and continuous. Transient intravenous injection is usually injected directly into the vein by syringe, which is the common "injection"; continuous intravenous injection is performed by intravenous drip, commonly known as "drip".
So under what circumstances can you not use disposable intravenous needle? First, the drug should not be taken orally, subcutaneously or intramuscularly. When rapid drug effect is required, intravenous or intravenous infusion can be used. Second, the drug is not suitable for other injection methods because of its high concentration, high irritation, and high volume. Third, for diagnosis and test, intravenous injection of drugs, such as liver, kidney, gallbladder and other X-ray films. Fourth, for intravenous nutrition therapy.
The common parts of the injection of in travenous needle are the expensive veins of the elbow fossa, the median vein, the cephalic vein, or the superficial veins of the back of the hand, the back of the foot, and the ankle.
