Injection needle

Injection needle

An injection needle is a tubular medical instrument with a wedge-shaped sharpening and a cannula for attaching to a syringe. It is designed to puncture various tissues of the human body in order to introduce liquid medications, solutions, blood or gases into them.

Injection needles are made of high quality medical grade stainless steel. Their size varies depending on the area of ​​application - for intramuscular, intravenous, subcutaneous injections. Needles can have different diameters (thickness) from very thin 0.3 mm to thicker 2 mm. Their length also varies.

The sharp wedge-shaped sharpening of the needle allows you to easily and painlessly (if the procedure is performed correctly) pierce the skin and penetrate the tissue. The smooth inner surface of the channel in the body of the needle ensures the free flow of injected liquids. The cannula at the end serves to connect the injection needle to the syringe using a threaded connection.

Injection needles are consumable, disposable materials, so after each procedure they must be disposed of in a special container. This reduces the risk of transmitting infections during repeated use. Compliance with the rules of asepsis and antisepsis when working with injection needles is extremely important for patient safety.

An injection needle (or a tubular needle with a wedge-shaped cannula at the end and attachment to a syringe) is a necessary tool for injecting liquids, gases and medications into various tissues of the body.

Injection needles can be of different lengths and diameters, depending on their purpose and the type of injection that needs to be performed. For example, short needles can be used for subcutaneous drug injections, while longer, thicker needles are used for intramuscular and intramuscular injections.
