OxyFlo Pro Probes
Introduction
A comprehensive range of Laser Doppler probes is available for use with
the OxyFlo Pro monitor, a description of which can be found on our website
(www.oxford-optronix.com).
All probes are comprised of a pair of 125 μm optical fibres, which are used
to direct low power laser light to and from the tissue. The fibres terminate at
one end of the probe in the probe head (of variable design, depending on
probe type) and at the other end in a connector plug that attaches to the
OxyFlo Pro. The connector plug is colour-coded with a
red
band.
OxyFlo Pro probes are either referred to as ‘dedicated blood flow probes’,
for the exclusive measurement of tissue blood flow, or as ‘combined
sensors’ for the simultaneous measurement of tissue blood flow and tissue
pO
2
/temperature, where the OxyFlo Pro is used in conjunction with its
optional counterpart, the OxyLite Pro.
The number of plugs on a sensor is dependent on the number of
parameters being measured. Dedicated blood flow probes feature a single
plug, while combined sensors featuring support for tissue pO
2
/temperature
measurements (and requiring the counterpart OxyLite Pro monitor), feature
two
connector plugs.
In the case of combined sensors, the connector plug carrying the
oxygen/temperature signal is colour coded with a
blue
band.
Probe Presentation
OxyFlo Pro probes consist of a pair of
optical fibres used to direct weak laser light
to and from the probe head.
The fibres terminate at one end in the probe
head (MSP300NX surface probe type
depicted here) and, at the other end, in a
connector plug that attaches to the OxyFlo
Pro (colour-coded with a red band).
A durable white silicone sleeving serves to
protect the optical fibres along the 3 m
length of the probe.
