OxyLab LDF Tissue Blood Flow MonitoringOxyLab LDF ™&OxyFlo ™

OxyLab LDF is a professional device used for blood flow measurement, equipped with laser Doppler technology and digital signal processing technology. It has the characteristics of measuring small blood vessel blood flow that other devices do not have, and can measure in real-time, continuously, and diversely. Multiple specifications of probes can be used for skin blood flow, brain tissue blood flow, muscle blood flow, tumor tissue blood flow, in vivo tissue and bone blood flow, etc. Especially, the Oxylab LDF probe can be used after high-pressure sterilization. It can be combined with OxyLb PO2 to achieve simultaneous and continuous measurement of multiple parameters. The OxyLab po2/LDF device is a combination of dissolved oxygen monitoring device (OxyLab po2) and tissue blood flow monitoring device (OxyLab LDF). It is possible to achieve continuous measurement of multiple parameters (tissue blood flow, dissolved oxygen, temperature) at the same location using the same probe.

Typical applications:
Peripheral vascular blood flow (peripheral vascular blood flow) monitoring
Cerebral perfusion monitoring in models of brain injury or stroke
Tumor perfusion monitoring
Blood flow monitoring of free flap and pedicle flap
wound healing
Gastrointestinal research
other

There are two types of tissue blood flow meters to choose from:

There are two models to choose from when combining a tissue blood flow monitor with a dissolved oxygen monitor:

OxyLab pO2 / OxyLab LDFSingle channel tissue blood flow/Blood oxygen /Temperature composite monitoring instrument

OxyLite / OxyFloMulti channel tissue blood flow/Blood oxygen /Temperature composite monitoring instrument

Laser blood flow probe
Mainly divided into surface probes, needle probes, and implantable probes (which can be used for long-term implanted blood flow monitoring)
