Abstract
A blood sampling device for allowing a fluid pressure measurement and a fluid sample to be taken from a patient, having an inlet port configured to receive blood from the patient, an outlet port configured to be coupled to a monitoring channel having an infusion fluid, a sampling port configured for extraction of blood from the patient, a sampling channel configured to self-flush, after extraction, the blood with the infusion fluid, and an auxiliary channel for self-flushing the sampling channel.
