Abstract

The invention concerns a wound contact means (12) for use in a reduced pressure wound treatment apparatus (10) including a wound contact means locatable on a wound, a vacuum pump (16) and a suction line (14) through which the vacuum pump can apply suction to a wound (26) through the wound contact means in order to draw wound exudate from the wound through the wound contact means. The wound contact means (12) of the invention is characterised in that it includes a mass of discrete particles (24) which are movable relative to one another to enable the mass of particles to be shaped to suit the wound. Furthermore the individual particles are of such shape and rigidity that when the particles are compacted together the particle mass exhibits porosity enabling wound exudate to pass through the mass. Another aspect of the invention concerns a reduced pressure wound treatment apparatus (10) which incorporates the wound contact means (12).
