A pliable pad includes a layer formed of an absorbent material and a formable material arranged generally parallel to each other. The selected formable material, such as aluminum foil, is capable of assuming a desired shape and of retaining the desired shape which has been assumed. As a result, the formable material can be shaped so that the pliable pad defines a basin for collecting and absorbing liquids. The pliable pad can also include one or more layers for defining a liquid barrier. The pliable pad can be used to collect excess liquid produced during a medical procedure, such as the irrigation of a wound, or can be used in other, non-medical applications in which liquid is to be collected.
