What is a hypodermic syringe?
Hypodermical syringe is a type of tube that can be mounted in hollow hypodermic needles for injection into or extraction from the body. The main body of the syringe is equipped with a firmly mounted font, which is used by sliding along the barrel, pulling or pushing the desired substance over the opposite end that is open. Most hypodermic syringes are made of plastic, although they can also be made of glass. A suitable dosage of medicine or vaccine is drawn into the syringe and then served by pushing into the piston to push out the liquid from the open end and the subcutaneous needle. Injections can be made directly into the body, for example to the muscle, or can be made by an intravenous line, which then transmits them to the bloodstream; The administration method depends on the drug.
Bloods can also be taken using a hypodermic syringe. The plon is attached to the hypodermic needle, which is inserted into the vein, then tightens backwards and creates suction. Blood is drawn this suction and goes to the syringe cylinder nobo sometimes in the attached tube that can be used to perform the necessary diagnostic tests on the blood.
When injected into a blood vessel with a hypodermic syringe, it is very important to ensure that there is no air in it. The reason is the risk of causing air embolism; This is when the air bubble enters the circulatory system where it can potentially lead to serious side effects. To avoid any air in the tube, those who serve the shot usually hold it upside down and eliminate a small amount of needle medicine first.
In medical environments, hypodermic syringes are generally disposable and used only Once and then discarded. This is to minimize the risk of transmission of the disease among patients. It has been shown that the reuse of needles is an important factor in the spread of diseases such as HIV; Those who share needles such as injection -like users such as heroin are often exposed tohigh risk. Some patients, such as diabetics who are injected every day, can reuse needles, but only on top of each other.
