SUNS SBH2000 Pneumatic Burst and Breathing Cycle Tester

Overview

The SUNS SBH2000 Pneumatic Burst and Breathing Cycle Tester is an engineered test platform designed for precise evaluation of pressure integrity, cyclic fatigue resistance, and ultimate failure behavior in medical respiratory devices, packaging systems, and flexible barrier materials. It operates on a controlled pneumatic principle—using regulated compressed air to apply calibrated, time-synchronized pressure loads—and conforms to the fundamental mechanical testing paradigms defined in ISO 11607-1 (packaging for terminally sterilized medical devices), ASTM F1886/F1886M (leak testing of porous medical packaging), and ISO 10993-1 (biocompatibility evaluation of device components under mechanical stress). Unlike generic pressure testers, the SBH2000 integrates synchronized timing, multi-mode pressure profiling, and deterministic I/O control to replicate physiologically relevant breathing waveforms (e.g., sinusoidal, square, ramped cycles) as well as static overpressure conditions required for burst validation per ISO 8536-4 (infusion equipment) and EN 868-5 (sterile barrier systems).

Key Features

• Triple-level pressure resolution support (0.1 kPa, 1 kPa, and 0.0001 MPa) enables high-fidelity detection of micro-leak events during low-pressure leak integrity tests and robust quantification of burst thresholds at elevated ranges.
• Selectable pressure regulation architecture: mechanical fine-tuning valves for manual calibration verification, or closed-loop electromechanical regulators with real-time feedback for automated, repeatable pressure ramping in breathing cycle protocols.
• Integrated 10-inch industrial-grade LCD touchscreen with intuitive HMI—designed for glove-compatible operation in cleanroom and QC lab environments—supports on-device test configuration, live pressure/time curve visualization, and pass/fail threshold annotation.
• Dual communication architecture: RS232/RS485 serial interface for legacy LIMS integration and hardware synchronization; RJ45 Ethernet port compliant with TCP/IP for remote monitoring, centralized data aggregation, and secure audit trail logging.
• Expandable I/O subsystem (6 digital inputs / 6 digital outputs) permits external triggering from auxiliary sensors (e.g., flow meters, displacement transducers) and coordinated actuation of peripheral hardware (e.g., solenoid valves, safety interlocks, chamber doors).

Sample Compatibility & Compliance

The SBH2000 accommodates a broad range of sample geometries—including endotracheal tubes, ventilator circuits, anesthesia masks, blister packs, pouches, and laminated films—via customizable fixture interfaces and modular pressure chambers. All pneumatic pathways are constructed from stainless steel and fluoropolymer-sealed components to ensure chemical compatibility with medical-grade cleaning agents and prevent particulate generation. The system supports full traceability requirements under ISO 13485:2016 and FDA 21 CFR Part 11 when paired with validated software (e.g., SUNS TestMaster Pro v3.2+), including electronic signatures, user-access controls, and immutable audit logs for all test parameters, results, and operator actions.

Software & Data Management

Test execution, parameter definition, and result analysis are managed through SUNS’ proprietary TestMaster Pro software suite—available as a standalone Windows application or network-deployed client-server module. Raw pressure vs. time datasets are captured at ≥100 Hz sampling rate and stored in vendor-neutral CSV and XML formats. Built-in statistical tools compute mean burst pressure, standard deviation across replicates, cycle-to-failure distributions, and trend analysis for accelerated aging studies. Data export via USB mass storage is fully compliant with GLP/GMP documentation workflows, supporting direct import into JMP, Minitab, or LabWare LIMS without format conversion.

Applications

• Validation of single-use respiratory circuit integrity under simulated clinical breathing profiles (e.g., 12–30 cycles/min, peak inspiratory pressures up to 40 cmH₂O equivalent).
• Burst pressure qualification of sterile barrier packaging per ISO 11607-2 Annex B, including edge seal strength and weld integrity assessment.
• Leak rate quantification in Class III medical devices using differential pressure decay methodology (ASTM F2096).
• Accelerated fatigue testing of silicone tubing, PVC connectors, and elastomeric seals subjected to repeated inflation/deflation cycles.
• Process validation support for packaging line qualification (IQ/OQ/PQ) and annual requalification per ISO 13485 clause 7.5.11.

FAQ

What regulatory standards does the SBH2000 directly support?
The instrument’s pressure accuracy (±0.2 % FS), timing resolution (0.1 s), and data traceability architecture align with ISO 11607-1, ASTM F1886, ISO 8536-4, and FDA guidance on container-closure integrity testing (CCIT) for sterile products.
Can the SBH2000 perform simultaneous multi-sample testing?
The base configuration supports one test channel; however, multi-channel expansion modules (up to 4 independent stations) are available as factory-installed options with synchronized master-slave pressure control.
Is the system compatible with 21 CFR Part 11-compliant electronic records?
Yes—when operated with SUNS TestMaster Pro v3.2 or later under a validated installation, the SBH2000 provides role-based access, electronic signatures, and tamper-evident audit trails meeting Part 11 Subpart B requirements.
What maintenance intervals are recommended for long-term accuracy retention?
Annual calibration verification against NIST-traceable pressure standards is advised; internal zero/span checks and filter replacement (inlet air dryer) should be performed quarterly per the maintenance logbook included with shipment.
