Amputations per Year

Out of the 60,000 amputations per year in Germany, 40,000 arise from Diabetes.*


Diabetic Foot Syndrom

About one quarter of diabetics will suffer from a diabetic foot syndrome during their disease.*


more PAOD Cases

Diabetics are 3 times more likely to be diagnosed with peripheral artery occlusive disease.*

One-Page Report

The one-page report combines pulse wave and measurement parameters on a single page at the touch of a button.

Simple Measuring Program in under 3 Minutes

The measurement can be conducted easily by following only a few steps and without significant strxess for the patient.

After applying the cuffs on ankles and wrists, as well as the optical sensors on the toes, the system applies a pressure of 180mmHg and decreases it by steps of 10mmHg.

By recording the optical sensors, the examiner can immediately determine the pressure step at which the patient’s toes show the first pulsations. Different key indicators, like the oABI, the amplitude or the peak time of the pulse wave, are recorded simultaneously.

The innovative TOPP method was developed in collaboration with:

Comprehensive Screening

The innovative method provides a fast and secure diagnosis of the peripheral vessel status of diabetics.

It allows measuring on ankle and wrists as well as on fingers and toes, including forefoot- and toe pressure measurement.

AngE DIABETIC combines four measuring cuffs and two optical sensors to enable the measurement on six measuring spots simultaneously. This creates diverse possibilities to detect blood flow disorders within the final current areas as well as to assess the wound healing success of diabetic patients.

The high sensitivity of the optical sensors allow for a good documentation of the pulse waves, even with marginal blood flow. Given the virtually unfiltered display of pulse curves, dicrotic waves can be clearly identified for healthy and elastic arteries.

I consider SOT to be the European market leader for D-PPG measurements. The AngE Phlebo is a miniaturized device with high-quality, sophisticated evaluation software.

Prof. Dr. Jaroslav Strejček
President of the Czech Society of Phlebology

The AngE Phlebo is the state-of-art, haemodynamically significant D-PPG system for venous diagnostics. This non-invasive functional investigation has always helped me accurately examine venous disorders, even with complex cases.
