SUNS SUNS Auto Dental Irrigator Tester

Overview

The SUNS Auto Dental Irrigator Tester is a purpose-built, automated functional verification system engineered for quality assurance laboratories, medical device manufacturers, and regulatory testing facilities evaluating dental water jet devices—commonly known as oral irrigators or water flossers. Unlike generic pressure or acoustic test benches, this instrument integrates calibrated force transduction, precision sound level measurement, and programmable fluidic actuation to replicate real-world clinical usage conditions. It operates on a deterministic test sequence: controlled air-driven activation of the irrigator unit, synchronized acquisition of dynamic output pressure (via high-stability load cell), concurrent A-weighted sound pressure level (SPL) recording (per IEC 61672-1 Class 2), and automatic pass/fail evaluation against user-defined thresholds. The system is designed for compliance with ISO 13485 quality management requirements and supports traceable validation protocols required under FDA 21 CFR Part 820 and EU MDR Annex II.

Key Features

• Integrated dual-parameter metrology: Simultaneous measurement of mechanical output force (0–500 g, 0.1 g resolution) and acoustic emission (30–120 dB(A), 0.1 dB resolution) under standardized test conditions.
• Configurable test logic engine: Programmable pass/fail criteria per parameter—including upper/lower limits, trend-based deviation detection, and multi-condition Boolean evaluation (e.g., “pressure ≥ 350 g AND noise ≤ 65 dB”).
• Automated fluidic interface: Onboard pneumatic control module delivers regulated, oil-free, dry compressed air (0.4–0.8 MPa) to trigger device actuation without manual intervention or external air sources.
• Industrial-grade human-machine interface: 7-inch capacitive touchscreen with intuitive test setup wizard, real-time waveform display (pressure vs. time, SPL vs. time), and context-sensitive help overlays.
• Regulatory-ready data architecture: All test records include timestamp, operator ID, device serial number, environmental conditions (ambient temperature/humidity), and digital signatures—fully compatible with 21 CFR Part 11 audit trail requirements when deployed with validated software configuration.
• Scalable hardware platform: Single-channel base configuration supports optional expansion to 4-channel parallel testing via modular I/O backplane—enabling batch throughput optimization for production line QC environments.

Sample Compatibility & Compliance

The tester accommodates all commercially available corded and cordless dental irrigators with standard nozzle interfaces (including universal bayonet, threaded, and quick-connect types). Fixture adaptability is ensured via adjustable mounting brackets and interchangeable nozzle holders compliant with ISO 20752:2020 Annex C dimensional references. All pressure transducers are factory-calibrated against NIST-traceable deadweight standards; sound calibrators meet IEC 60942 Class 2 specifications. The system’s electromagnetic compatibility conforms to EN 61326-1:2013 for laboratory equipment, and its electrical safety complies with IEC 61010-1:2010. Documentation packages include IQ/OQ templates aligned with ISO/IEC 17025 clause 5.5.2 for measurement equipment validation.

Software & Data Management

Built-in embedded Linux OS runs SUNS TestSuite v3.2 firmware—certified for GLP/GMP-aligned operation. Each test generates a structured XML report containing raw sensor traces, statistical summaries (mean, SD, min/max), and annotated pass/fail status. Reports export directly to USB mass storage in CSV, PDF, or XML formats. Optional network integration enables secure HTTPS upload to LIMS or MES platforms via RJ45 Ethernet (TLS 1.2 encrypted). Audit logs record every configuration change, calibration event, and user login—retained for ≥18 months with automatic rollover. Remote diagnostics and firmware updates are supported via authenticated SSH session (key-pair authentication enforced).

Applications

• Final functional verification of Class IIa dental irrigators prior to release (per ISO 13485 clause 8.2.5).
• Design verification testing during new product development (NPD), including durability assessment across 10,000+ actuation cycles.
• Supplier qualification audits requiring objective, repeatable performance benchmarking (e.g., comparing OEM vs. contract manufacturer output consistency).
• Regulatory submission support: Generating test evidence for FDA 510(k), CE Technical File, or Health Canada license applications.
• Root cause analysis of field complaints related to low output pressure or excessive operational noise.

FAQ

Does the system support calibration certificate issuance per ISO/IEC 17025?
Yes—calibration services are available through SUNS-accredited partners, with certificates documenting measurement uncertainty, traceability to national standards, and environmental conditions at time of calibration.
Can test parameters be locked to prevent unauthorized modification?
Yes—role-based access control (RBAC) enforces three permission tiers: Operator (test execution only), Technician (calibration and maintenance), and Administrator (full configuration, user management, and audit log review). Password policies comply with NIST SP 800-63B.
Is pneumatic air supply included with the instrument?
No—the unit requires an externally supplied clean, dry, oil-free compressed air source meeting ISO 8573-1 Class 2:2:2 specifications. An optional integrated air dryer/filter module (SUNS-AF-01) is available for purchase.
What is the maximum allowable ambient humidity for continuous operation?
The system is rated for continuous use at ≤80% relative humidity, non-condensing, within the 5–45 °C operating temperature range. Condensation detection circuitry triggers automatic shutdown if internal dew point sensors exceed threshold.
How is firmware update integrity verified?
All firmware images are cryptographically signed using SHA-256 and RSA-2048. The bootloader validates signature authenticity before installation, rejecting any tampered or unsigned binaries.
