PeriFlux System 5000 - laser Doppler and transcutaneous oxygen

PeriFlux System 5000 is used in specialist clinics and laboratories worldwide for precise micro- and macrovascular assessments.

The system consists of main units and function units. Several main units, each equipped with 4 function units, can be connected with each other in order to achieve the desired number of channels.

The modular design enables the simultaneous monitoring of (laser Doppler) blood flow / perfusion and transcutaneous oxygen (TCOM, tcpO2) and/or carbon dioxide. Function units for heat provocation and pressure control are also available as well as a wide range of laser Doppler probes. 

Combined with Perimed’s dedicated software, the system offers complete and customized solutions for safe, smooth and simple workflows to investigate and assess the microcirculation.

The main units are:

PF 5001 Main Unit
PF 5002 Basic Main Unit

The four function units are:

PF 5010 LDPM Unit
The PF 5010 LDPM Unit (Laser Doppler Perfusion Monitoring) is used for blood perfusion measurements based on laser Doppler technology. Laser Doppler measures the total, local microvascular flow including capillaries, arterioles, venules and shunts. One laser Doppler probe is used per unit.

With the PF 5010 LDPM Unit you can closely follow the dynamic changes in the microcirculation. Heart synchronous pulsations and even dicrotic notches can be observed. The system is also useful for studying responses to provocations such as heating, occlusion, drugs, posture, electrical stimulation, etc.

PF 5020 Temp Unit
The PF 5020 Temperature Unit is used to perform local heat provocation and/or temperature measurements. The PF 5020 unit has two connectors for either thermostatic laser Doppler probes and/or temperature measurement sensors.

Thermostatic laser Doppler probes allow for precise heating of the tissue at the measurement site. This can for example be useful to study the tissue reserve capacity.

PF 5040 tcpO2/pCO2 Unit
The PF 5040 tcpO2/pCO2 Unit measures the local tissue oxygenation or local carbon dioxide tension. The oxygen derives only from the local capillary (nutritive) blood perfusion. The carbon dioxide level is affected by both the local metabolic processes and the blood perfusion ability to remove carbon dioxide. One Clarke type electrode is used per unit.

PF 5050 Pressure Unit
The PF 5050 Pressure Unit is used to control linear or instant cuff pressure deflation. It has been developed to simplify and standardize tests such as peripheral pressure measurements (toe and ankle pressures), Skin Perfusion Pressure (SPP) and post occlusive reactive hyperemia (PORH). The PF 5050 Pressure unit can also be used to monitor cuff pressure with a precision sufficient for Pulse Volume Recordings (PVR).
