Device and method for automatically venting and filling a catheter

An apparatus for the automatic deaerating and filling of a catheter connected to a blood vessel of a patient with blood comprising

• a fluid channel section for guiding fluid flows,
• a deaeration device for deaerating the catheter,
• wherein the fluid channel section comprises:
• at least one fluid channel through which fluids can flow,
• a blood inflow channel configured for catheter attachment and for a fluid connection to the fluid channel,
• an air outflow channel configured for a fluid connection to the fluid channel and the deaeration device such that air can be conveyed out of the fluid channel and out of the catheter connected to the blood inflow channel through the air outflow channel by means of the deaeration device, whereby the catheter connected to the blood vessel and the fluid channel can be filled with blood,
• wherein the apparatus comprises a sensor device designed to measure the deaerating and/or filling of the fluid channel and to generate a measurement signal containing information on the deaerating and/or filling of the fluid channel, and wherein the apparatus comprises a control device having electrical circuitry which is configured to automatically control the deaeration device for deaerating and/or filling the fluid channel as a function of the measurement signal.
