Stainless Steel Bevelled Solid Core Needle Tube, SUS304 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.

• 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.
