a wound dressing configured to cover and protect a wound, the wound dressing comprising:
a backing layer;
a wound contact layer configured to contact the wound; and
an absorbent material positioned between the wound contact layer and the backing layer; and

a negative pressure source configured to apply negative pressure to the wound, the negative pressure source being integral with the wound dressing, wherein the negative pressure source comprises:
