Spring-Loaded Blood Collection Needle 28G
HENAN AILE INDUSTRIAL CO., LTD with over 12 years of medical experience.
We hold certifications, including CE, ISO 13485 & USA FDA.

Auto-retraction safety mechanism to prevent needlestick injury Dual-spring driving construction. The needle penetrates skin instantly upon pressing and retracts and locks inside plastic housing right after sampling. The used needle stays concealed permanently to eliminate accidental pricking risk for healthcare workers and patients, meeting safety protocols of hospital clinical labs and physical examination centers.
Low-pain fast puncture with fixed depth Triple-bevel polished needle tip with silicone lubricant coating. Ultra-fast penetration and fixed puncture stroke, free from force fluctuation from manual operation. It reduces irritation to subcutaneous nerve and greatly eases pain. Multiple puncture depths are available to match different skin thickness for adults, elderly and pediatric patients.
Simple one-handed operation Pre-assembled all-in-one structure. No lancet pen assembly needed. Remove protective cap, press gently against sampling site to trigger blood collection. Easy for new medical staff and home users, ideal for mass physical screening and outpatient rapid blood testing.
Individual sterile packaging for stable hygiene Individually sealed unit packaging to block dust and bacterial contamination. Gamma irradiation or EO sterilization optional, 3-year shelf life. Easy storage and transportation for hospitals, clinics and cross-border medical distributors.
Full-size options for wide application Complete gauge range from 21G to 33G, puncture depth 1.2mm~2.5mm. Color-coded housing for quick visual identification. Suitable for blood glucose testing, capillary blood routine test, blood group screening, POCT in-vitro diagnosis and other capillary sampling scenarios.
Biocompatible non-allergic raw materials All human-contact components adopt medical-grade raw materials, free from heavy metals and harmful plasticizers. Pass biocompatibility test with low skin irritation, suitable for patients requiring frequent blood sampling.

Spring-Loaded Blood Collection Needle, also known as auto-retractable safety lancet or disposable capillary blood collection lancet, is a single-use minimally invasive medical device widely used in clinical laboratories and home health monitoring. Equipped with a precision spring trigger mechanism, it adopts an integrated safety design: press to activate, instant skin puncture, and the needle automatically retracts and locks after blood sampling. No extra lancet pen required, fingertip or earlobe capillary blood collection can be completed with one hand.
As mainstream blood sampling consumables adopted by medical facilities, testing labs and diabetes home monitoring programs worldwide, spring loaded blood collection needle solves the defects of traditional manual triangular lancets and ordinary blood needles: uncontrollable puncture force, high risk of needlestick injury, severe pain and cross-contamination from repeated use. Each unit is individually packed under sterile conditions, sterilized by EO ethylene oxide or gamma irradiation. It is for single use only. Once activated, the needle retracts and locks inside the housing permanently, preventing accidental needlestick injuries and transmission of blood-borne pathogens such as HBV, HCV and HIV. It complies with ISO13485 medical quality management system, CE MDR and other international medical standards.

Different parts of spring loaded blood collection needle adopt dedicated medical raw materials. Material selection directly affects puncture smoothness, safety and product stability.
Needle: 304 medical stainless steel Standard mainstream material, rust-proof, high tensile strength, easy for sharp edge polishing with stable silicone coating adhesion and good biocompatibility, ideal for clinical blood sampling. Low-cost alternatives use ordinary 201 stainless steel with insufficient hardness, burr risk, rusting tendency and metal precipitation allergy risk, not recommended for clinical usage.
Housing: ABS vs LDPE ABS: high rigidity, anti-drop, stable printing for professional hospital-grade lancets. LDPE: softer texture, gentle pressing touch, lower cost for basic home blood glucose monitoring.
Spring: Galvanized carbon steel wire Medical galvanized spring maintains stable elasticity without fatigue after repeated compression, ensuring consistent puncture depth batch by batch. Non-galvanized cheap springs tend to rust and unstable elasticity, leading to insufficient or over-deep puncture.
Note: Material certificates and biocompatibility reports can be provided for overseas registration submission.

Collect capillary blood samples from fingertip, earlobe and other peripheral sites for in-vitro diagnostic tests: blood glucose test, hemoglobin test, capillary blood routine screening, blood grouping, POCT rapid diagnosis and infectious disease screening. Only for capillary blood sampling, NOT for venipuncture or injection.
Target Users:
Diabetic patients for regular home blood glucose monitoring (28G/30G thin gauge recommended for frequent sampling).
General adult capillary blood collection in hospital outpatient and health check centers.
Elderly patients with thin fragile skin.
Children and infants (small gauge & shallow puncture depth to reduce fear and pain).
Primary care clinics, community screening, mobile medical and field diagnostic projects.

Consistent puncture performance: Precision spring calibration, minimal deviation of puncture depth per batch, stable blood sample quality, less hemolysis to guarantee accurate test results.
Safety locking system: Permanent needle lock after sampling, non-reusable, meeting safety regulations in European and American medical institutions and reducing medical disputes from needlestick injury.
Full customization capability: Customizable gauge, puncture depth, housing color, outer printing, neutral packing or OEM private label. Flexible MOQ for B2B bulk foreign trade orders.
Complete compliance documents: ISO13485, CE MDR, sterilization certificate, material report and biocompatibility report available to support customers’ overseas registration including Saudi SFDA, Brazil ANVISA, Bangladesh UNBS.
Direct factory supply with stable delivery: Manufactured in medical cleanroom, capable of large volume orders, fast sample delivery, neutral export packing for cross-border e-commerce, overseas distributors and hospital tender projects.
Low-pain design improves patient compliance: Triple-bevel tip with silicone lubricant reduces skin tearing. Higher acceptance among pediatric patients and long-term glucose monitoring users, improving blood sampling experience in medical facilities.

Q1: Can Spring-Loaded Blood Collection Needle be reused? A: No. It is single-use medical device. The needle retracts and locks permanently after use and cannot be triggered again. Reuse causes cross infection and dull needle tip with severe medical risks. Dispose into sharps container after use.
Q2: How to select different gauge sizes? A: Higher G number means thinner needle. 30G/32G for children, elderly and daily diabetic glucose monitoring with less pain. 26G/28G universal gauge for adult routine check-up. 21G/23G thicker needle for large blood volume requirement or thick calloused skin.
Q3: What is the difference between EO sterilization and gamma irradiation? A: EO ethylene oxide has strong penetration for plastic parts and needs residual gas desorption after sterilization. Gamma ray irradiation requires no desorption, fast sterilization without chemical residue, widely preferred for EU & US export. Both options available.
Q4: Will needle jam occur during auto-retraction? A: Spring trigger structure is fully inspected during production with batch reliability test. No jam under proper operation. Do not press against hard objects to avoid mechanism damage.
Q5: What is storage requirement? A: Store in cool dry place, avoid direct sunlight, high temperature and humidity. Storage temperature 5~30℃. Use within shelf life. Discard if package broken.
Q6: Can we do OEM private label and neutral packing? A: Yes. Custom housing color, customer logo printing, customized color box. Neutral non-brand packing for overseas distributor tender and e-commerce sales.
Q7: Can you provide samples for testing? A: Yes, full range samples available with quality certificate. Sample freight can be negotiated.
Q8: What medical device class is this product? A: Spring loaded capillary lancet belongs to low-risk single-use medical device. Classification varies by country regulation. We can supply documents to assist local authority registration.
