1. A negative pressure wound therapy system, comprising:
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:
a manually compressible chamber; and
a one-way valve;
wherein a compressive force applied to the manually compressible chamber moves fluid through the one-way valve and release of the compressive force on the manually compressible chamber creates a negative pressure at the wound.
