A drainage device for the treatment of wounds using reduced pressure, includes (a) a gas-type wound-covering element, which is fastened cohesively at the skin surface around the region of the wound and forms a sealed wound space, remaining between the respective wound and the wound-covering element; (b) at least one drainage tube, which can be connected to a device generating reduced pressure and can be inserted into the wound space approximately parallel to the wound-covering element; and (c) at least one absorption body in the form of at least one layer of a textile section, which is interspersed with super-absorbing particles and enclosed in an envelope. Due to the size of the pores of the envelope, the absorbed wound secretions remain within the absorption body and underneath the wound-covering element until the absorption body is removed from the wound space. An air opening is provided for the wound-covering element.
