What is Biofilm?

Biofilm is a mucous substance that bacteria secrete and in which they embed themselves. Biofilms are part of the bacterial defences against the immune system and constitute a barrier to the body’s immune cells as these encounter considerable difficulties penetrating the biofilm in order to target the bacteria inside. Biofilms are complex structures with well organised own…

Can MPPT harm the wound bed?

MPPT sucks the exudate fluid away from the wound surface by means of capillary forces. Capillary forces automatically stop the sucking action as soon as there is no longer any excess fluid present because air will enter the system and break the continuous water column. Consequently, the suction can never cause harm to the wound bed.

Can MPPT over-dry the wound?

MPPT sucks the exudate fluid away from the wound surface by means of capillary forces. Capillary forces only work when there is excess fluid present. Therefore, the suction stops automatically as soon as there is no longer any excess fluid present and, consequently, there will never be any suction effect exerted on the wound bed itself.

What is capillary action / capillary forces?

Capillary action is the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension. In less technical terms, capillary action occurs because water is sticky, which means that water molecules stick to each other and to other materials. Sticking to the walls of a tube or pore…

How does MPPT work (MoA)?

MPPT works in three steps: Absorption, Pumping by capillary forces and Evaporation. The Exudate is absorbed into the MPPT micropore particles. These are highly porous and the pores (or capillaries) are interconnected. The capillaries work as a battery of small individual pumps that by means of capillary forces suck ( pumps) the exudate to the surface of…
