Medical Disposable Sterile 28G Needle Pressure-Activated Auto-Retracting Safety Blood Lancet for Painless Sampling

In-depth Product Introduction

In clinical diagnostics and personal health monitoring, peripheral blood sampling is the first and most critical step. This Medical Disposable Sterile Finger Blood Sampling 28G Square Safety Blood Lancet is specifically engineered for medical environments that demand maximum safety and minimal pain.

The core technology lies in its pressure-activation system. Unlike traditional lancets, this product features a square-shaped body for a more stable grip, preventing slippage during operation. The built-in 28G ultra-fine medical-grade stainless steel needle is precision-polished and siliconized to penetrate the skin at high speed and retract automatically, effectively eliminating the risk of secondary needle-stick injuries and cross-infection.

Core Product Advantages

• Safety First: The needle is permanently locked and retracted into the protective shell immediately after activation, complying with OSHA safety standards and completely preventing needle-stick injuries.

• Minimal Pain: The high-performance 28G needle (approx. 0.36mm diameter) minimizes stimulation of pain nerves while ensuring sufficient blood flow.

• Pre-armed Design: No complex caps to remove; blood sampling is completed through simple pressure contact, streamlining the nursing workflow.

• Consistent Blood Flow: Precise spring tension ensures a consistent penetration depth every time, resulting in high-quality blood samples.

Technical Specifications

Material Distinction and Selection

When choosing a safety lancet, the materials determine the safety and quality grade:

• Needle Material: We use 304 medical-grade stainless steel. Compared to ordinary steel, it offers superior toughness and corrosion resistance. The needle tip is tri-bevel ground to reduce resistance when entering the skin.

• Housing Material: We select 100% virgin medical-grade ABS plastic rather than recycled materials. Virgin ABS provides better chemical stability and mechanical strength, ensuring the trigger mechanism does not deform or fail under pressure.

Target Users and Applications

• Clinical Departments: Suitable for routine blood glucose, blood counts, and various Point-of-Care Testing (POCT) in pediatrics, endocrinology, and laboratory departments.

• Personal Care: Highly recommended for diabetic patients who need daily glucose monitoring; the 28G gauge is very gentle for users with thinner skin on their fingertips.

• Screening Programs: Ideal for mobile blood collection, large-scale infectious disease screening, or community health check-ups.

FAQ

• Q: What is the difference between 28G and 21G?

  • A: The higher the G-value, the thinner the needle. 28G is much thinner than 21G and is primarily used for blood glucose monitoring; 21G is typically used for tests requiring higher blood volume (such as hemoglobin testing).

• Q: Can the needle be reused?

  • A: Absolutely not. This product features a one-time locking function; the needle cannot be popped out again after use.

• Q: Does it contain latex?

  • A: It is Latex-Free, making it safe for individuals with latex allergies.
