The GBPI GB-SBP is a specialized laboratory synthetic blood penetration tester engineered to evaluate the fluid splash resistance and liquid barrier performance of medical face masks, surgical coverings, protective drapes, and fluid-resistant healthcare apparel. Built in strict accordance with ASTM F1862 (standard test method for resistance of medical face masks to penetration by synthetic blood) and ISO 22609 (clothing for protection against infectious agents — medical face masks — test method for resistance against penetration by synthetic blood fixed volume, horizontally projected), this instrument verifies high-velocity liquid pathogen barrier protection.
During surgical operations, dental procedures, and trauma clinical interventions, healthcare personnel face substantial risks from high-pressure spurts of arterial blood and infectious body fluids. If outer non-woven fabric layers possess insufficient liquid repellency or surface tension resistance, biological fluids penetrate through to the inner lining, exposing clinicians to viral cross-contamination. Operating as an automated synthetic blood penetration tester, the GBPI GB-SBP projects a 2 mL volume of prepared synthetic blood horizontally across a fixed 300 mm trajectory against the outer surface of a clamped mask specimen at precise arterial blood pressure velocities.
Calibrated Pressure Velocity Regimes
The instrument incorporates precision pneumatic timing and pressure regulation circuitry that reproduces three critical clinical cardiovascular pressure levels: 10.6 kPa (80 mmHg simulating venous/low-pressure bleeding), 16.0 kPa (120 mmHg simulating standard arterial pressure), and 21.3 kPa (160 mmHg simulating hypertensive systolic arterial spurts). A microsecond-response solenoid valve actuates the calibrated cannula nozzle, delivering the exact fluid volume within a controlled time window of 0.01 to 0.1 seconds.
Curved Headform & Flat Specimen Versatility
The instrument features both a realistic curved human facial headform for evaluating fully assembled pleated, cone, and duckbill surgical masks, as well as an interchangeable flat specimen clamping fixture (75 mm by 75 mm) for characterising raw spunbond-meltblown-spunbond (SMS) composite fabrics.
With an intuitive color touchscreen, automated pressure stabilization, and an easy-clean splash containment tray, the GB-SBP serves as an indispensable tool for surgical mask CE Type IIR and ASTM Level 1, 2, and 3 fluid barrier certifications.
