Stainless Steel Bevelled Solid Core Needle Tube, ISO9626 304 Blood Lancet For Sample Collection
1. Definition:
A precision-engineered, solid cylindrical rod manufactured from Grade 304 Stainless Steel, conforming to ISO 9626 standards for medical needle tubing. Despite the term "tube," it features a solid core (no lumen) and a bevelled sharp point. It serves as the piercing element in single-use blood lancets for capillary blood sampling (finger/heel sticks). This component is the critical functional part of a blood lancet. Its purpose is to create a quick, controlled, minimally traumatic puncture in the skin to access capillary blood for glucose testing, hemoglobin checks, or other point-of-care diagnostics. Compliance with ISO 9626 ensures consistent dimensions, material properties, and biocompatibility. The "solid core" distinguishes it from hollow hypodermic needles.
2. Key Properties:
- Corrosion Resistance: Excellent resistance to bodily fluids, sweat, and sterilization processes.
- Strength & Rigidity: High tensile strength prevents bending/buckling during skin puncture.
- Formability: Can be precision-ground and bevelled.
- Non-Magnetic: Austenitic structure is essentially non-magnetic.
3. Characteristics:
- Minimizes insertion force and tissue trauma.
- Designed for rapid skin penetration and clean wound formation.
- No secondary grind (e.g., Pencil Point) is used, as fluid aspiration isn't required.
- Solid Core: Eliminates risk of coring (tissue plug occlusion) and provides superior column strength.
- Precision Bevel: Ensures sharpness, low penetration force, and consistent depth control. Asymmetrical conical grind creating a sharp, chisel-like cutting edge.
4. Manufacturing Process:
- Wire Drawing: Cold-drawn to precise diameter per ISO 9626.
- Centerless Grinding: Achieves tight OD tolerances and surface finish.
- Pointing/Bevelling: Precision grinding forms the bevel edge.
- Cleaning & Degreasing: Removes contaminants.
5. Applications:
- Primary: Single-Use Blood Lancets for:
- Glucose monitoring (diabetes management).
- Point-of-Care HbA1c, cholesterol, or coagulation tests.
- Neonatal heel-stick sampling.
- Veterinary capillary blood sampling.
- Secondary: Components in automated lancing devices or micro-sampling systems.
