The invention relates to a method for testing at least one function of a medical functional device which is inserted in and connected and compressed with a medical treatment apparatus, and/or a function of this treatment apparatus, wherein between a hydraulic device or a pneumatic unit of the treatment apparatus and the functional device at least one fluid communication is established. It further relates to a detection device which is programmed and/or configured for executing the method according to the invention as well as a medical treatment apparatus which comprises at least one detection device and/or is in signal transmission or is connected for signal transmission with it, a digital storage medium, a computer program product as well as a computer program.

An apparatus and method for blood treatment for the single-needle mode, the apparatus having an extra-corporeal blood circuit with a blood infeed line running to the inlet and a blood return line leading away from the outlet, of a blood treating unit, includes in the blood return line a device, e.g., container, for amassing blood, which is in flow-permitting connection for gas transfer with a device, e.g., container, for storing gas. A pressure is calculated and set in the device for storing gas before the arterial and venous phases are started, with two constraints. First, the pressure should be sufficiently low to ensure both no infusion of air into the patient and also regulated flow of blood into the patient even at opposing pressures lower than ambient pressure. Second, the pressure should be sufficiently high to expel blood from the device for amassing blood into the device for storing gas.
