Abstract
A connector includes a body having a tubular cavity connected to two ducts and includes an infusion aperture for infusing a liquid into the line and a sampling aperture for sampling blood. A constriction having a diameter progressively decreasing towards the inlet aperture is disposed in the cavity between the two apertures and produces a Venturi tube effect, preventing the sampled blood from being affected by the infused liquid.
