A connection device, for mechanical ventilation and monitoring of spontaneous breathing of a patient (P), includes a fluid-guiding unit () and establishes a fluid connection between a medical arrangement () and a patient-side coupling unit (). A volume flow sensor () measures an indicator of volume flow of fluid through the fluid-guiding unit. A volume flow sensor component () engages with an interior of the fluid-guiding unit. A homogenization unit () is nonrotatably inserted into the interior between the patient-side coupling unit and the component and includes two sieves and a connection element, which connects the sieves together. The homogenization unit homogenizes the flow of fluid through the fluid-guiding unit. An inner profile of the fluid-guiding unit and an outer profile of the homogenization unit together form a mechanical coding, which determines a defined rotation position of the homogenization unit in relation to the fluid-guiding unit.
