Medical Stainless Steel Intravenous Injection Needle Tube , ISO9626 SUS304 , 25G 0.5*34MM
Introduction:
Stainless steel intravenous needle tubes are critical components in medical devices designed for delivering fluids, medications, or drawing blood. Intravenous injection needle tubes allow the administration of a liquid (often a drug solution) directly into the person's vein. Their design prioritizes patient comfort, safety, and efficacy, leveraging stainless steel's unique properties. These intravenous injection needle tubes are generally made by medical-grade stainless steel material (e.g., SUS304, SUS316L), because these materials have superior strength compared to plastics, excellent resistance to corrosion compared to other metals, and good durability for precise skin penetration. Our company can customize intravenous injection needle tubes with different shape needle points according to clients' requirements. All of our needle tubes' quality meet the requirement of EN ISO13485: 2016 international standard.
Characteristics of Medical Intravenous (IV) Injection Needle Tubes:
1.Biocompatibility
- Suitable for prolonged contact with blood and tissues.
2.Mechanical Properties
- High Strength and Ductility: Balances rigidity for skin penetration with flexibility to avoid breakage. Achieved via cold working and annealing.
- Thin-Wall Design: Maximizes internal diameter for optimal fluid flow while maintaining structural integrity.
3.Surface Finish
- Electropolished to achieve a smooth, microbe-resistant surface, reducing friction during insertion and minimizing tissue trauma.
- Low surface roughness prevents bacterial adhesion and enhances corrosion resistance.
4.Sharpness and Precision
- Laser-cut or ground tips ensure ultra-sharp bevels for painless venipuncture and reduced insertion force.
- Consistent tip geometry (e.g., 15–20° bevel angle) improves success rates and patient comfort.
Applications:
- Gauge Variability: Ranges from 14G (large, for trauma) to 27G (fine, for pediatrics).
- Clinical Uses: IV therapy, blood collection, catheters, and specialized devices like infusion pumps.
- Adaptability: Compatible with various medical solutions, including hypertonic fluids and contrast agents
Some Frequently Asked Questions (FAQs) About IV Needles:
1.Why is stainless steel used for IV needles?
Stainless steel is preferred for its strength, resistance to rust and corrosion, and biocompatibility. It maintains structural integrity during insertion and minimizes the risk of material reactions in the body.
2.What are the different types of IV needles?
IV needles vary by gauge (thickness) and length. Common gauges range from 14G (thick) to 27G (thin), with smaller gauges used for delicate veins (e.g., pediatrics) and larger ones for rapid fluid delivery.
3.Can IV needles be reused?
No. Reuse poses serious infection risks and compromises sterility. IV needles are single-use and must be discarded after each procedure.
4.How should needles be stored?
Store in a cool, dry place, away from direct sunlight. Ensure packaging remains sealed until use to maintain sterility.
5.Why is needle bevel design important?
A sharp, angled bevel eases skin penetration and reduces discomfort. The bevel length may vary for different vein depths.
