Wound therapy device for the treatment of wounds by means of negative pressure and fluid irrigation, comprising a negative-pressure dressing, a pressure sensor means, which can generate pressure measurement values in order to determine the negative pressure present in the negative-pressure dressing, a drainage container for collecting liquid, and a drainage line by means of which liquid can be conveyed from the negative-pressure dressing into the drainage container. The device also comprises a first pump unit for aspirating liquid from the wound space via the drainage line, wherein the first pump unit is connected in a fluid-conducting manner to the drainage container. The device also comprises an instillation container for making available an instillation fluid, an instillation line by means of which instillation fluid can be delivered from the instillation container into the wound space, means for delivering an instillation fluid from the instillation container into the wound space, and control means, wherein the pressure sensor means forward the pressure measurement values to the control means. According to the invention, the device is characterized in that, when a predefined upper negative-pressure threshold value is reached in the wound space, the control means can output a signal to switch off the first pump unit, and in that, when a predefined lower negative-pressure threshold value is reached in the wound space, the control means can output a signal to interrupt the delivery of the instillation fluid. |
