Needles

Needles for Injections, Infusions and Venepuncture

Sterile needles and cannulas are essential consumables in modern healthcare and are used every day for injections, infusions, blood collection and punctures. Depending on the application, needles differ in diameter, length, bevel design and connection type. Choosing the right needle ensures safe, efficient and tissue-friendly procedures.

Needles are used for a wide range of applications, including intramuscular, subcutaneous and intravenous injections, infusion therapy and diagnostic procedures such as blood sampling. Special draw-up and transfer needles are also available for safely withdrawing, mixing and transferring medication.

At Praxisdienst, you will find a comprehensive range of sterile needles and cannulas for professional use in medical practices, hospitals and care facilities. Our selection includes injection needles, safety needles, butterfly needles, IV catheters, draw-up needles and transfer needles in various sizes and designs.

Which needle is suitable for which application?

The correct needle depends on the intended application, injection technique and requirements for safety, flow rate and handling. The following needle types are commonly used in medical practices, hospitals and care facilities.

Injection needles

Injection needles are suitable for intramuscular, subcutaneous and intravenous injections. The appropriate size depends on the injection site, administration method and viscosity of the medication.

Draw-up and transfer needles

Draw-up needles and transfer needles are designed for withdrawing, mixing and transferring liquids from ampoules, medication vials or infusion containers.

Blunt needles

Blunt needles feature a non-sharp tip and are used for gentle application or aspiration of fluids, for example during wound care procedures.

Safety needles

Safety needles have integrated protective mechanisms that cover or secure the needle tip after use, helping to minimise the risk of needlestick injuries.

Butterfly needles

Butterfly needles, also known as winged infusion sets, enable controlled venepuncture and are particularly suitable for patients with difficult venous access.

IV catheters

IV catheters are used when fluids, infusion solutions or medication need to be administered repeatedly or over a longer period of time.

Needle features and selection criteria

Which needle size is required?

The needle diameter is specified in gauge (G) and affects both flow rate and patient comfort. Smaller gauge needles are often used for subcutaneous injections and delicate veins, while larger diameters are suitable for higher-viscosity solutions or applications requiring a higher flow rate.

What needle length is suitable?

The required needle length depends on the injection method and application site. Shorter needles are commonly used for subcutaneous injections, while longer needles are required for intramuscular applications.

What is the needle bevel?

The needle bevel describes the angled cut at the needle tip. A precisely manufactured bevel supports smooth tissue penetration and enables gentle, low-trauma punctures.

Luer or Luer-Lock connection?

Luer connections are attached by pushing the needle onto the syringe, while Luer-Lock connections are secured with a screw mechanism. Luer-Lock provides a particularly reliable connection, especially for applications involving increased pressure.

When should safety needles be used?

Safety needles are recommended whenever additional protection against needlestick injuries is required. Their integrated safety features help secure the needle tip immediately after use and support safer working processes.
