Filtrass science is a innovative new type of plethysmograph. Fully integreated and equipped with a patented and re-designed electromechanical sensor it allows for a state of the art plethysmographic assessment of the microcirculation. Mircovascular permeability, and the balance of Starling forces can be measured non invasively. The most recent protocol enables the assessment of lymph flow in the limb.

The data can be analysed off - line on your PC using Filtrass viewer. For data transfer the inbuild Ethernet connection or a disk can be used.

Blood flow data and venous assessment can be printed out directly and added to the patient records if required.

The new innovative electromechanical sensor allows for a

• automated
• self calibrating
• very precise (accuracy of < 5 µm)
• mercury free

measurement of limb circumference

Filtrass science compromises of:

• Integrated Filtrass unit
• 2 electromechanical sensors
• 2 cuffs
• 2 x Photoplethysmograph

software package for the assessment of

• filtration coefficient (kf)
• isovolumetric venous pressure (pvi)
• venous pressure (pv)
• venous compliance

venous and arterial disease

• arterial blood flow
• venous outflow dynamics
  
  

Filtrass allows plethysmogaphic measurements of arm and leg.

The Following protocols can be performed

• Automated arterial blood flow measurement
• Reactive Hyperemia
• Muscle pump test
