    摘要: A wound therapy system includes a canister configured to contain fluid removed from a wound site, a primary conduit having a first end coupled to the canister and a second end coupled to the wound site, and a pump fluidly coupled to the wound site via the primary conduit. The pump is configured to apply negative pressure to the wound site via the primary conduit. The system includes a pressure indicator configured to indicate a negative pressure at the pressure indicator and a secondary conduit having a first end coupled to the pressure indicator and a second end coupled to the wound site such that the negative pressure at the wound site is fluidly transmitted to the pressure indicator via the secondary conduit. A blockage in the primary conduit causes the negative pressure indicated by the pressure indicator to differ from the negative pressure applied by the pump.
