A Guide to Choosing and Using Needles and Syringes

by UKMEDI 15 Sep 2023

Needles and syringes are vital tools in many medical and scientific applications. Choosing the right needle and syringe for a particular application can be a complex task, as there are many factors to consider. This guide provides an overview of the main factors to consider when selecting a needle and syringe, and offers some tips on how to use them effectively.

The Different Types of Syringes

There are two main types of syringes: disposable and reusable. Disposable syringes are made of plastic and are intended for one-time use only.

Reusable syringes are made of glass and can be used multiple times. Disposable syringes are less expensive and more convenient than reusable syringes. However, they can only be used once and must be disposed of properly to avoid contamination. Reusable syringes are more expensive than disposable syringes, but they can be used multiple times. They must be sterilized between uses to prevent contamination.

Syringe Nozzle Type

Luer Slip: The Luer slip syringe is the most common type of syringe. It consists of a barrel and a plunger that fits snugly inside the barrel. The plunger has a small tip that fits into the needle. To use the syringe, the plunger is pulled back to draw the desired amount of fluid into the barrel. The needle is then inserted into the desired injection site, and the plunger is pushed to inject the fluid.

Luer Lock: The Luer lock syringe is similar to the Luer slip syringe, but it has a locking mechanism that secures the needle to the barrel. This type of syringe is used when repeated injections are required, such as when administering medication over some time.

Luer Slip Eccentric: The Luer slip eccentric syringe is similar to the Luer slip syringe, but the needle is offset from the centre of the barrel. This type of syringe is used when injections must be given at an angle, such as when injecting into the thigh.

Catheter: A catheter is a thin, flexible tube that is inserted into the body through a needle. Catheters are used when injections must be given directly into a vein or artery.

Factors to Consider When Choosing a Needle and Syringe

1. Type of Medication

Different medications require different types of needles and syringes. For example, insulin must be injected with a needle that is small enough to prevent damage to the insulin molecules.

2. Route of Administration

The route of administration (oral, intravenous, intramuscular, etc.) will dictate the type of needle and syringe that is required.

3. Age of the Patient

Needles and syringes come in different sizes to accommodate different age groups. For example, pediatric needles are smaller than needles used for adults.

4. Safety Features

Some needles and syringes come with safety features, such as retractable needles, that help to prevent accidental needle sticks.

5. Syringe Capacity

Syringes come in different sizes, from 1 mL to 60 mL. The size of the syringe you need will depend on the amount of medication you need to inject.

Tips on Using Syringe and Needles Safely

1. Only Use New Syringes and Needles

If you are using drugs, it is important to always use new syringes and needles. Do not reuse syringes or needles.

2. Do Not Share Syringes or Needles

Sharing syringes and needles puts you at risk for HIV, hepatitis C, and other blood-borne infections.

3. Dispose of Used Syringes and Needles Safely

You can get free disposal containers from some needle exchange programs. You can also buy disposal containers at some pharmacies.

4. Do Not Cut or Break Needles

Do not cut or break needles. Doing this can increase your risk for infection.

5. Clean the Injection Site

Clean the injection site with soap and water before injecting.


The selection of needles and syringes is an important decision that healthcare providers must make to ensure patient safety and comfort. There are various needle and syringe types available on the market, each with its own advantages and disadvantages. Healthcare providers should select the needle and syringe type that best meets the needs of their patients.

Needles and syringes must be used correctly to be effective. Healthcare providers should be properly trained in the use of needles and syringes before using them on patients. Improper use of needles and syringes can lead to patient injury and disease transmission.

Needles and syringes are essential tools in the healthcare setting. They must be used correctly to ensure patient safety and comfort.
