Disposable Sterile injection needles are Disposable scalp vein needle a common medical appliance. As early as the 15th century, the principle of the syringe was proposed. The needle or the liquid is mainly extracted or injected.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.Disposable sterile injection needles can also be used in medical devices, containers, and scientific instruments such as some chromatographic instruments to inject through a rubber diaphragm.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".The emergence of disposable sterile injection needles is an epoch-making revolution in the field of medical appliances. The emergence of syringes is an epoch-making revolution in the field of medical appliances and the process of needle extraction or infusion of gas or liquid is called injection. The syringe consists of a syringe with a small hole at the front end and a matching piston rod for injecting a small amount of liquid into the area that is inaccessible to other methods or from those places.
The liquid is pulled out when the core rod is pulled out. Or the gas is drawn in from the small hole at the front end of the barrel, and the liquid or gas is squeezed out when the core rod is pushed in.Disposable sterile injection needles consist of a syringe with a small hole at the front end and a matching piston rod for injecting a small amount of liquid into the area that is inaccessible by other methods or extracting from those places, pulling out the core rod at the time, the liquid or gas is sucked from the small hole at the front end of the barrel, and the liquid or gas is squeezed out when the core rod is pushed in. It is widely used in medicine.
