PressCise – Controlled bandage compression by mathematics

We have developed a unique bandage that provides a well defined pressure. By following the markings on the bandage as you wrap, you get the right overlap and a defined pressure for each turn. Regardless of who applies the bandage, or the circumference of the leg, PressCise will provide a well defined pressure.

Medical need

A large proportion of the adult population suffers from so-called venous insufficiency, prevalence is 10-15% in men and 20-25% in women. That is when the valves in the veins no longer are able to return the blood properly to the heart. This often leads to venous leg ulcers, or varicose veins. Approximately 30% of the population suffer from varicose veins, often treated with varicose vein surgery. In both cases, compression is essential for optimal healing.

Today’s problem

If you apply a bandage with too low pressure, you will get no compression effect, which can result in bruises and pain for the patient. If you put too much pressure on, the patient feels tingling and pain in the toes, in worst case, it leads to skin necrosis if you don’t redo the bandage application.

Today’s solution

The experience and “fingertip feel” of the bandage applier, is currently the only thing one has to rely on.

Mathematical & textile innovation

The underlying scientifically background behind the bandage is that mechanical factors were analysed. We have slightly extended the formulation of the Laplace’s Law, to three, instead of two factors. That is, the pressure obtained by a compression bandage depends on the following three factors: the longitudinal tension in the bandage (force), the thickness (the overlap for each turn) and the curvature of the profile of the object (here: the leg).

By following the markings on the bandage when you wrap, you get a constant overlap and defined pressure for each turn.

The benefits of PressCise

  • Selectable level of compression
  • Reduces no of wrong applied bandages
  • Same pressure regardless of leg size
  • Increased user safety
  • Increased patient safety
