The Kurin Blood Culture Collection Set is intended to obtain blood samples through the patient's vasculature via venipuncture or Peripheral IV (PIV) access. As it enters the Kurin Lock, blood initially fills a side channel then flows into the sample collection device (syringe or bottle) via an adjoining sampling channel to reduce blood culture contamination rates *. When supplied with a pressure-rated extension set, the pressure-rated extension set is intended to be utilized separately with infusions systems to administer IV fluids, medications, blood products into the patient's vascular system and may be safely used with power injectors at pressures up to 325 psi. *The Kurin Blood Collection System is for use as a blood collection system and its Kurin Lock allows the specimen of blood from the patient to be sidelined prior to the test sample to reduce the frequency of blood culture contamination when contaminates are present in the initial blood sample compared to blood cultures drawn using standard practice without the Kurin Lock.

The Kurin Blood Culture Collection Set is a sterile, single-use device that includes a vasculature connection (i.e., winged needle, male luer connection), flexible tubing, blood lock mechanism, and blood culture bottle holder (when supplied). The blood culture bottle holder varies between device models. Refer to the primary labeling for the compatible culture bottle. The Subject Device is intended to be used with the adult and pediatric population. The main purpose of the Subject Device is to obtain blood samples by transferring from the patient to a culture bottle or collection container. Venipuncture sets incorporate a needle-safe feature that covers the needle prior to disposal to aid in the prevention of needlestick injury if activated after the blood draws. Venipuncture needles include 21 and 23 gauge. Various Peripheral IV (PIV) sets incorporate a pressure-rated extension set with slide clamp that, when detached from the blood culture collection set, can be used for infusion purposes. The unique technology with the Subject Device is the blood lock mechanism (i.e., Kurin Lock). Upon access to the patient's vasculature, the Subject Device uses the patient's blood pressure to push an initial portion of blood that could contain bacterial contaminants (e.g., skin plugs) into the side channel. After the side channel is filled, flow stops until a collection device (i.e., blood culture bottle, vacutainer tube, syringe) is attached. The attachment of a collection device draws additional blood through the Subject Device and into the collection device. The initial portion of blood in the side channel is not isolated from this additional incoming blood, the amount of contamination reaching the collection device is dramatically reduced.
