Wound treatment system includes that a wound treatment device and a kind of wound dressing are connected to described device. Rumour dressing, which includes foaming structure wound insert, has bigger cross-sectional area with hole, when in terms of first direction with lesser cross-sectional area, when from an orthogonal direction. Method, which makes the material that this wound insert may include compression foam structure hole, has substantially homogeneous cross-sectional area. Method for treating wound uses wound insert.
