Hesley TD5A PRP/PPP Clinical Centrifuge for Aesthetic Medicine

Overview

The Hesley TD5A PRP/PPP Clinical Centrifuge is an engineered benchtop centrifuge specifically designed for point-of-care preparation of Platelet-Rich Plasma (PRP) and Platelet-Poor Plasma (PPP) in aesthetic medicine, regenerative dermatology, and minimally invasive surgical workflows. It operates on the principle of differential sedimentation under controlled low-speed centrifugation—optimized to separate whole blood into distinct, clinically usable layers without platelet activation or leukocyte contamination. Unlike general-purpose laboratory centrifuges, the TD5A integrates a horizontally swinging rotor system that enables direct centrifugation of clinical-grade syringes (10 mL, 20 mL, and 50 mL) and proprietary PRP collection tubes under aseptic conditions. Its fixed-angle rotor alternative supports high-yield PPP isolation for fat grafting refinement. The device complies with international standards for medical device manufacturing and is validated for use in GLP-aligned clinical environments where traceability, reproducibility, and biosafety are critical.

Key Features

• Brushless DC motor with microprocessor-based speed and RCF control ensures stable rotational performance at up to 4000 rpm and 2100 ×g, with speed accuracy maintained within ±50 rpm.
• Dual-mode operation interface: TFT-LCD color display with both touch-sensitive and physical keypad controls; real-time dual-parameter display (set vs. actual speed, time, RCF) allows dynamic parameter adjustment during active runs.
• Biosafe swing-out rotor assembly featuring integrated silicone elastomer sealing (EU RoHS 2015/863 compliant) prevents aerosol leakage during deceleration and enhances operator safety during open-lid handling.
• Triple-stage damping system—including asymmetric counterweight balance, rubber-isolated motor mount, and reinforced chassis—minimizes vibration and eliminates sample resuspension risks during low-speed separation protocols.
• Autoclavable rotor and adapter set (up to 134 °C, 2 bar steam sterilization) supports repeated reuse in sterile field applications, reducing consumable dependency and cross-contamination risk in outpatient clinics.
• Comprehensive safety architecture: over-speed, over-temperature, imbalance, under-voltage, and over-voltage detection; automatic rotor recognition; electromagnetic door lock with soft-close actuation; and stainless-steel 304 centrifuge chamber with triple-layer steel housing.

Sample Compatibility & Compliance

The TD5A accommodates standard Luer-lock syringes (10 mL, 20 mL, 50 mL) and certified PRP separation tubes (e.g., RegenKit®, Eclipse®, or custom OEM formats) without adapters. Its horizontal rotor geometry maintains vertical orientation of syringes throughout centrifugation—preserving stratified plasma layers essential for PRP layer harvesting. All wetted components meet ISO 10993 biocompatibility requirements. The unit is CE-marked per MDR 2017/745 Annex II Class IIa classification and carries CFDA registration (NMPA Class II medical device). It supports audit readiness for FDA 21 CFR Part 11–compliant data logging when paired with optional PC interface software (RS232/USB). Documentation includes full traceable calibration records, material declarations, and sterilization validation summaries.

Software & Data Management

While the TD5A operates as a standalone instrument, its embedded firmware supports export of run logs (date/time stamp, rotor ID, speed, duration, RCF, error codes) via USB port for integration into clinic-wide electronic health record (EHR) systems. Optional Hesley CentriLog™ software provides GMP-style electronic signatures, user access levels (admin/operator), and automated PDF report generation compliant with ISO/IEC 17025 documentation practices. Audit trails include timestamped entries for parameter changes, rotor installation, and maintenance events—supporting internal quality audits and external regulatory inspections.

Applications

• Preparation of autologous PRP for facial rejuvenation, hair restoration (androgenetic alopecia), peri-orbital rejuvenation (dark circles, lower lid laxity), and scar remodeling.
• Isolation of PPP for adipose-derived stem cell (ADSC) enrichment and stromal vascular fraction (SVF) processing in structural fat grafting procedures.
• Standardized separation of whole blood into buffy coat, platelet-rich plasma, and platelet-poor plasma layers per ASTM F2843-21 guidelines for regenerative biologics.
• Point-of-care processing in ambulatory surgery centers (ASCs), dermatology clinics, and aesthetic medical practices requiring rapid (<15 min), closed-system blood component isolation.

FAQ

Can the TD5A centrifuge process blood directly in syringes without tube transfer?
Yes—the horizontal rotor accepts Luer-lock syringes (10 mL, 20 mL, 50 mL) vertically oriented, eliminating pipetting steps and minimizing hemolysis or platelet activation.

Is rotor sterilization validated per EN 285 or ISO 17665?
The swing-out rotor and adapters are validated for steam sterilization at 134 °C, 2 bar for 5 minutes per ISO 17665-1:2019 Annex D protocols; full validation reports available upon request.

Does the centrifuge support multi-user access control and electronic signatures?
With optional CentriLog™ software, it supports role-based login, digital signature capture, and ALCOA+ compliant data archiving aligned with 21 CFR Part 11 Subpart B.

What regulatory certifications does the TD5A hold for clinical use in the EU and US?
It holds CFDA registration (China), ISO 13485:2016 certification, and CE marking under MDR 2017/745 Class IIa. FDA 510(k) clearance is not held; users must verify local regulatory pathway eligibility.

Can custom rotors be developed for non-standard PRP tube formats?
Yes—Hesley offers OEM rotor engineering services with lead times of 8–12 weeks; mechanical drawings and dimensional specifications required for quotation.
