1. A mobile negative pressure wound therapy (NPWT) device, comprising:
a housing,
a negative pressure pump arranged within the housing,
a canister fluidly coupled to the negative pressure pump and to a wound cover, the wound cover provided for creating a sealed space defined in part by a wound site,
a battery arranged within the housing, and
a control unit arranged within the housing, the control unit being electrically connected to the battery and adapted to provide power to the negative pressure pump for operating the negative pressure pump to establish a negative pressure within the sealed space, wherein the NPWT device further comprises control circuitry provided externally from the control unit and adapted to receive, directly from a pressure sensor, a signal corresponding to a pressure measurement, wherein the control circuitry is configured to terminate the operation of the negative pressure pump independently of the control unit if the NPWT device is determined to operate outside of a predefined negative pressure range.
