The blood leak detector BLD is a non-invasive optical sensor, developed to detect smallest amounts of blood in clear fl uids on transparent plastic tubing. It was designed for medical devices such as dialysis machines.
As blood should not cross the blood / dialysate membrane, each dialysis machine needs a detector to monitor blood leaks. The optical sensor uses a light source with an opti-mum wavelength in order to provide the best sensitivity regarding the detection of the red blood cells. A threshold
Highly resistant to ambient light

Customized designs available
Wavelength and sensitivity adjustable to different applications
Easy parameterization and testing
Made in Germany
triggers an alarm if the amount of blood in the fl uid exceeds the limits. The required sensitivity is defi ned by the inter-national standard IEC 60602-2-16. Accordingly, the sensor detects 0.35 ml / min of blood at a hematocrit level of 0.32 at the maximum specifi ed fl ow rate. Sophisticated algorithms in the sensor guarantee an excellent protection against ambient light. The sensor can be easily adjusted to similar applicati-ons by selecting a light source with a different wavelength. Modifi cations of the design or interfaces are available as customer-specifi c solutions.
