A device for administering an infusion or transfusion of liquid from a container includes a pump for pumping liquid to a patient connection via a conduit having a liquid-retaining filter membrane. The device also includes a pressure measuring device for acquiring measurement values corresponding to a pump-inlet-side pressure, and a control device for detecting a change in the pump-inlet-side pressure based on the measurement values. The control device determines, based on the change in the pump-inlet-side pressure, whether to stop pumping. The control device also generates a control signal when the pumping is to be stopped. Moreover, the control device emits, based on the control signal, a communication signal to a data connection between the device and a unit that reads the communication signal. In addition, or in the alternative, the control device switches the device from a first state to a second state based on the control signal.
