OxyLab LDF
and
OxyFlo
|
|
|
Tissue blood perfusion is a primary factor in the
transport of heat, drugs, oxygen, waste products and
nutrients around the body and its measurement provides
researchers with critical information in a number of
clinical and research applications.
The latest generation systems incorporate new
developments in Digital Signal Processing (DSP) and laser Doppler flowmetry providing a technologically advanced, yet simple to use for multi-channel monitoring, setting new standards
for reliability and robustness.

|
Key Features
|
|
|
Whether your application requires the strikingly
designed, multi-channel OxyFlo system or the single
channel OxyLab LDF monitor, you will benefit from the
following features:
|
|
 |
Real
time blood perfusion measurement from up to 4 tissue
sites simultaneously - for studying spatial as well as
temporal perfusion heterogeneity and comparisons of
pathological versus control tissue sites.
|
|
|
OxyFlo
systems include unique Artefact Rejection Technology
(ART™) enabling blood perfusion measurements to be
obtained in hitherto difficult or impossible dynamic
‘moving tissue’ applications.
|
|
|
Multi-parameter monitoring. Both OxyFlo and OxyLab LDF
systems can be combined with their oxygen monitoring
counterparts, enabling the simultaneous measurement of
ptO2, blood perfusion and temperature from the same
tissue site using a single sensor.
|
|
|
Extensive range of fiber optic sensors for perfusion
monitoring from virtually any tissue type/site.
|
|
|
Rapid
response times for real-time monitoring, capable of
resolving perfusion changes occurring over fractions
of a second.
|
|
|
Plug
and play - No user input or configuration required.
|
|
|
‘Smart
sensors’ - Automated sensor.
|
|
|
identification allows one-time sensor calibration.
|
|
|
Unique
autoclaveable sensors - Re-usable type sensors can be
steam-sterilized.
