1. What Is A Hypodermic Syringe

The hypodermic syringe is a kind of tube that can be installed on the needle of a hollow hypodermic syringe, and is used to inject into or pull out of the body. The main body of the syringe is provided with a closely matched plunger, which is used by sliding along the tube barrel and sucking in or pushing out the required substance through the open another end. Most hypodermic syringes are made of plastic, but they can also be made of glass.

2. What Are Hypodermic Syringes Used For

One of the main usages of hypodermic syringes is to inject drugs and vaccines. The appropriate dose of drug or vaccine is inhaled into the syringe, and then the liquid flows out from the open end by pushing the plunger, or through the subcutaneous injection needle. The injection can be injected directly into the body, such as muscle or through intravenous injection they can be delivered to the blood; The method of administration depends on the drug.

3. Points For Attention In Using Hypodermic Syringes

When a hypodermic syringe is being used to inject blood vessels, it is very important to ensure that there is no air in the blood vessels. This is due to the risk of air embolism; This is a serious side effect resulting from bubbles entering the circulatory system. In order to avoid any air in the tube, the syringe is usually inverted and a small amount of drug is discharged from the needle first.

In the medical environment, hypodermic syringes are usually disposable, used only once, and then discarded. This is to minimize the risk of disease transmission between patients.
