Understanding Scalp Vein Sets And Choosing The Right One

Understanding Scalp Vein Set

Scalp vein set, commonly referred to as winged infusion set, is a medical device specifically designed for puncturing superficial veins, particularly in areas such as the scalp, the back of the hand, or the wrist. Its primary purpose is to facilitate intravenous injections or blood sample collection for treatment purposes.

This device features a precise design to ensure stability and safety during the puncture process. Based on locking mechanisms and catheter structure, scalp vein set types are categorized into: single-wing Luer lock type, single-wing Luer slip type, butterfly-wing Luer lock type, and butterfly-wing Luer slip type. Different sizes can meet the specific requirements of various patient age groups and clinical scenarios.

Scalp Vein Set Uses

Scalp vein sets are primarily used for:

Venous blood sample collection: Serving as an important route for obtaining patient blood samples for various laboratory biochemical, immunological, microbiological, and hematological tests and analyses.

Intravenous fluid therapy and infusion: A fundamental means to achieve fluid resuscitation, maintain electrolyte and acid–base balance, and replenish nutrients and energy, especially suitable for patients who cannot tolerate oral intake or have large volume requirements.

Intravenous drug administration: An effective channel for the rapid and accurate delivery of various therapeutic drugs — including emergency medications, antibiotics, chemotherapeutic agents, and analgesics — ensuring direct entry into the circulatory system.

Perioperative management in plastic surgery: During facial or body contouring plastic surgery, it provides stable support for perioperative intravenous medication, anesthesia induction and maintenance, fluid management, and potential blood transfusion.

Components of a Scalp Vein Set

①Subcutaneous needle – A protective outer casing for the hollow metal puncture needle, ensuring safe withdrawal of the needle core after venipuncture is completed.

②Wing – Refers to a single- or double-sided flexible flap structure that allows the operator to securely grip and stabilize it against the skin.

③Flexible transparent tube – A 20–25 cm medical-grade tube with excellent biocompatibility and transparency, allowing real-time observation of infusion flow and backflow of blood.

④Connector with Luer lock or slip – Serves as the terminal interface of the catheter. The Luer lock type uses a twist-lock mechanism to ensure a secure connection, while the slip type allows quick insertion and removal; both reliably connect with infusion sets or syringes.

⑤Plastic cap – A sterile protective cover for the needle tip or connector, maintaining sterility before use and covering sharp points after use to prevent accidental needle-stick injuries.

Advantages of Scalp Vein Sets

Thanks to their refined design and high-precision tubing, scalp vein sets can efficiently and stably access small veins, significantly improving puncture and treatment accuracy while minimizing pain and discomfort from the procedure.

The ultra-fine puncture system allows effective access to fragile, delicate veins, greatly enhancing vessel localization accuracy and puncture success rates. The flexible catheter material reduces friction with the vessel wall during insertion and indwelling, minimizing pain and discomfort, thereby improving patient compliance.

In terms of safety, the specially designed catheter wall can effectively reduce the risk of accidental infiltration of drugs or fluids. The biocompatible materials used are minimally irritating and, compared to traditional metal needles, significantly reduce the risk of vascular endothelium damage, venous irritation, and phlebitis. Catheter removal exerts minimal traction on the vessel and skin, making the process easier and reducing the risk of tissue injury or scarring from long-term placement. This makes them an ideal choice for short-term infusion therapy.

Regarding operational flexibility, the lightweight design and extended tubing length provide healthcare personnel with greater positional adjustment and management freedom. The multi-functional capability of the device is particularly notable, allowing seamless adaptation to venous blood collection, continuous drug infusion, and contrast agent injection in high-demand scenarios, meeting diverse clinical treatment needs and improving nursing efficiency.

Factors to Consider When Choosing a Scalp Vein Set

Needle gauge

Select the needle gauge size precisely according to the patient’s vascular characteristics and specific infusion rate requirements. A gauge that is too large or too small can affect puncture results and infusion efficiency.

Safety features

Give priority to products equipped with an integrated safety device to prevent needle-stick injuries and with a controllable safety locking mechanism to minimize occupational exposure and blood-borne infection risks for healthcare workers.

Compatibility

Strictly verify whether the set is reliably compatible with the venous blood collection devices, infusion tubing connectors, and infusion pump equipment used in established clinical workflows.

Sterilization method

The product should clearly indicate compliance with medical-grade sterilization standards (such as ethylene oxide or irradiation sterilization) and ensure that the individual packaging is intact, providing traceable sterile assurance.

Brand reputation

Focus on the manufacturer’s long-term market performance, including clinical adverse event records, quality management system certifications, and actual feedback from professional medical user groups.

Budget considerations

Under the premise of fully meeting basic performance and patient safety standards, evaluate the total cost of ownership — including initial purchase cost, associated consumable expenses, and potential costs of managing clinical complications.

Training and support

Ensure that the supplier can provide standardized on-site operational skills training, detailed technical documentation, and an ongoing after-sales technical consultation channel with a rapid response mechanism for urgent issues.

Conclusion

As a precisely designed superficial vein access device, the scalp vein set’s core value lies in its accurate needle gauge matching, biocompatible materials, and safety locking structure, which significantly enhance puncture success rates and patient comfort. When selecting a product, it is necessary to comprehensively consider safety protection features, device compatibility, and sterilization assurance, while balancing clinical needs with cost-effectiveness.

To ensure consistent access to reliable products that meet strict standards, medical institutions should give preference to suppliers who can provide complete technical training and after-sales support systems.
