Detailed Description

The utility model is described below with reference to the accompanying drawings and examples.

As shown in the attached drawing, the medical wound dressing capable of draining the effusion comprises a dressing body 1, a plurality of drainage through holes 2 capable of leading out the effusion of the wound are arranged on the dressing body 1, and the drainage through holes are arranged on the dressing to ensure that the effusion of the wound can be smoothly led out, prevent the infection of the wound and accelerate the healing of the wound.

The number of the drainage through holes 2 arranged on the dressing body 1 is 10-1800 per 100cm²The number of drainage through holes 2 is set within this range to ensure the best drainage effect.

The shape of the drainage through hole 2 is a circular through hole, or a vertical bar-shaped through hole, or an oval through hole, or a rhombic through hole, or a triangular through hole, or a rectangular through hole, or various irregular through holes.
