Abstract
The invention relates to a test unit for wound drainage coverings comprising: a base body with at least one cavity; at least one supply line that runs through the base body and which connects an outer side of the base body to the cavity; a surface of the base body that is embodied as a support surface for supporting wound coverings and the wound drainage coverings thereof and several channels that run through the base body, the channels connecting the cavities to the support surface. Low pressure can be produced in the cavity and the channels when the support surface is covered in an air-tight manner. As a result, wound drainage applications are tested in different ways using simple and economical means.
