Abstract: A flush syringe with a syringe coupler facilitates twice dispensing of intravenous flushing solution to a patient's vascular access device (VAD), with reduced risk of VAD infection. The syringe coupler incorporates a female, first Luer connector on its proximal end that is removably coupled to the male, barrel Luer connector of the syringe, isolating the latter connector from external contamination. The syringe coupler also has a single-use, male, second Luer connector on its distal end of the housing that is adapted for coupled insertion into the patient's VAD, for delivery of at least a portion of the flushing solution retained within the syringe. After the first delivery, the syringe coupler is de-coupled from both the VAD and the syringe. Thereafter, the syringe's unused, sterile, male, barrel Luer connector is directly coupled to the VAD for dispensing the second portion of the flushing solution.
