Blood Leak Detector
Optical Clamp-On Sensor BLD for Contactless Detection of Smallest Traces of Human Blood
The optical sensor BLD detects non-invasively smallest amounts of blood in clear fluids on transparent flexible plastic tubing. According to the medical safety standard IEC 60601-2-16:2018, the sensor reliably recognizes 0.35 ml/min of blood at a flow rate of 800 ml/min and a hematocrit level of 32 %. A proven hardware design and advanced algorithms guarantee excellent protection against ambient light.

Measurement Principle
Optical Transmission Measurement
The blood leak detector BLD measures the quantity of transmitted light in liquid-filled tubes. The measuring cell consists of a light source and a photodiode. The emitted light of the LED (light emitting diode) passes the tube before it reaches the LDC (light to digital converter). The LDC measures the light intensity, which is evaluated by the firmware. With increasing contamination, the intensity of light decreases as a consequence of absorption and reflection. The measured quantity of the transmitted light is compared to a calibrated reference value. An alert is raised by the sensor if the attenuation of the light intensity related to the calibrated reference value is larger than a given threshold.
