Calibration

trublu® calibration device

With the aid of the trublu® calibration device, all sensors of the pedar® and pliance® system are individually calibrated using a known air pressure. This procedure is computer-assisted and can be performed in a short time. Calibration guarantees accurate and reproducible data. The calibration curves, one for each sensor, can be checked by the user at any time. This method guarantees the accuracy of the absolute values measured, not only for the total force, but also for the local load on each area of the measured area.

trublu calibration

The trublu® calibration device can be delivered with the pedar®/pliance® system and the user can test the accuracy of the equipment at any time.

The systems are delivered with calibrated measurement sensors. Calibration should be checked at least once a year.

Accuracy and Reproducibility

Pressure Distribution Measurement Management at novel gmbh
Many clinicians daily assess the dynamic pressure distribution of the patient’s foot and make clinical decisions based on this data. Accurate and reliable pressure information is indispensable for the clinician to decide for appropriate treatment. Depending on the loading pattern of the foot and the pathology of the patient the local pressure values of the foot can reach up to 1.2 MPa, or even higher [1]. The actual value of local pressure is extremely important in patients with pathologies such as the diabetic foot. Therefore, it is necessary that every sensor within a pressure system displays the accurate, absolute pressure value.

Accurate plantar pressure measurements are mandatory in both clinical and research contexts. Differences in accuracy, precision and reliability of the available devices have prevented so far the onset of standardization processes or the definition of reliable reference datasets.
