Product catalog summary
Overview
The Blood Leak Detector BLD03 is a non-invasive optical sensor designed to detect small amounts of blood in clear fluids within transparent flexible plastic tubing. It is intended for integration into medical devices and can be used in various healthcare settings, including hospitals and home care applications like home dialysis.
Specifications
  • Detection capability: 0.35 ml/min of blood at a hematocrit level of 32% with a dialysis fluid flow rate of 800 ml/min.
  • Compliance with medical safety standard IEC 60601-2-16:2018.
  • Highly resistant to ambient light interference.
  • Digital electronics and advanced algorithms for enhanced patient safety.
Key Features
  • Internal self-test routines for reliable performance.
  • Calibration at the customer site for optimal performance.
  • Special algorithms for evaluating measurement data plausibility.
  • Compliance with IEC 60601-1-2:2014 (4th edition), AMD1:2020 for electromagnetic compatibility.
  • Software classification according to IEC 62304:2006, AMD1:2015.
Measurement Principle
The BLD03 uses optical transmission measurement, where a light source and photodiode measure the light intensity passing through liquid-filled tubes. The sensor raises an alert if the light intensity attenuation exceeds a calibrated reference threshold.
Technical Data
  • Response time: 280 ms ± 10 ms.
  • Measurement channel dimensions: Width 5.0 mm, Height 5.8 mm.
  • Compatible tubing: Transparent flexible plastic with an outer diameter of 5.5 to 7.0 mm.
  • Operating voltage: +3.1 to +5.5 VDC.
  • Operating temperature: +5 to +50 °C.
  • Protection class: Sensor head IP65.
Application
The BLD03 is used in hemodialysis to detect blood leaks in the dialysate, preventing unwanted blood loss due to membrane rupture in the dialyzer. It works alongside the SONOCHECK ABD05 air bubble detector to ensure patient safety by monitoring blood circulation and preventing air embolisms.
