Coring vs. Non-Coring Huber Needles: Differences, Selection and Usage Guidelines

Huber needles are specialized puncture needles used in the medical field for a wide range of applications such as long-term intravenous infusions, chemotherapy drug delivery, and nutritional support. Unlike ordinary needles, Huber needles have a unique beveled design and puncture pattern that reduces damage to blood vessels and surrounding tissues. However, Huber needles are categorized as Coring and Non-Coring, which have significant differences in effectiveness and safety. In this article, we will explain the differences between these two types of needles and guide you in choosing the right Huber needle for your needs.

What is a Huber needle?

A Huber needle is a blunt-tipped puncture needle with a beveled tip rather than the traditional sharp shape. This design allows the needle to penetrate the skin and blood vessel walls in a “non-cutting” manner, thereby reducing tissue damage and pain. Huber needles are commonly used in the following scenarios:

Long-term intravenous infusions (e.g. chemotherapy drugs, antibiotics, etc.)

Nutritional support (e.g. parenteral nutrition)

Hemodialysis

Implantable infusion port (Port) puncture

The advantage of Huber needles over conventional needles is their ability to repeat punctures with less vascular damage, making them particularly suitable for patients requiring long-term treatment.

Differences between Coring and Non-Coring Huber Needles

1. Coring Huber needles

Coring Huber needles may “core” during puncture, which means that the needle cuts away part of the septum or tissue as it penetrates, forming tiny particles. These particles can enter the blood vessel or infusion system and cause the following problems:

Dislodgment of septal particles: Increases the risk of catheter blockage.

Risk of infection: The particles may carry bacteria and cause infection.

Drug contamination: particles may affect the purity and effectiveness of the drug.

Coring needles are usually used in scenarios that do not require frequent punctures, but they have a high potential risk and therefore require extra care when used.

2. Non-Coring Huber needles

Non-Coring Huber needles are specially designed to avoid cutting the septum or tissue during puncture, thus avoiding the “core” phenomenon altogether. Advantages include:

Reduced septal damage: extends the life of the implantable port.

Reduced risk of infection: Avoids particles entering the blood vessel or infusion system.

Improved safety: particularly suitable for patients requiring prolonged or frequent punctures.

Non-Coring needles are now the mainstream choice in healthcare, especially in chemotherapy and long-term infusion therapy.

How to choose the right Huber needle?

Choosing the right Huber needle needs to be determined on a patient-by-patient basis and based on treatment needs. Here are some key considerations:

Treatment cycle:

If the patient requires long-term or frequent punctures (e.g., chemotherapy patients), a Non-Coring needle is recommended.

For short-term or low-frequency punctures, Coring needles may be more economical.

Drug type:

For highly concentrated or harsh drugs, Non-Coring needles provide better septal protection and reduce the risk of drug leakage.

Patient condition:

For patients with low immunity or susceptibility to infection, Non-Coring needles are a safer option.

Device compatibility:

Ensure that the selected needle is compatible with implantable infusion ports or other medical devices.

Precautions for Using Huber Needles

To ensure the safety and effectiveness of Huber needles, the following precautions should be taken when using them:

Proper puncture technique:

When using Huber needles, puncture the septum vertically at a 90-degree angle, avoiding oblique or repeated punctures.

Sterilization and Care:

Thoroughly sterilize the skin and needle before puncture.

Replace needles regularly to avoid infection from prolonged use.

Potential Risk Prevention:

Use Non-Coring needles to minimize the risk of septal injury and infection.

Regularly check infusion ports and catheters to ensure they are clear and free of infection.

Conclusion

Coring and Non-Coring Huber needles differ significantly in design and function, and choosing the right needle is critical to patient outcomes and safety. Non-Coring needles have become the preferred choice for long-term therapy due to their superior safety and durability. If you or your patients require the use of Huber needles, it is important to consult with a healthcare professional to ensure the most appropriate option is selected.
