BLD Blood Leak Detector

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
- Detects 0.35 ml/min of blood at a hematocrit level of 32% with a dialysis fluid flow rate of 800 ml/min.
- Complies with medical safety standard IEC 60601-2-16:2018.
- Resistant to ambient light interference.
- Utilizes digital electronics and advanced algorithms for enhanced patient safety.

Key Features
- Internal self-test routines for reliable performance.
- Calibration at customer site for optimal performance.
- Special algorithms for data plausibility evaluation.
- Certified for medical safety and electromagnetic compatibility.

Measurement Principle
The BLD03 uses optical transmission measurement, where a light source and photodiode measure the light intensity passing through liquid-filled tubes. A decrease in light intensity indicates contamination, triggering an alert if it surpasses a threshold.

Technical Data
- Measuring Method: Optical transmission measurement
- Response Time: 280 ms ± 10 ms
- Measurement Channel: Width 5.0 mm, Height 5.8 mm
- Tubing: Transparent flexible plastic, Outer Diameter 5.5 – 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 blood loss due to membrane rupture in the dialyzer. It works alongside the SONOCHECK ABD05 to monitor for air bubbles, which could cause air embolisms.

Sales & Support
Certified according to ISO 9001 and EN ISO 13485, SONOTEC GmbH provides support for the BLD03.
