PROCOAGULANT FACTORS SUITABLE FOR SUBSEQUENT AUTOLOGOUS USE
A blood collection unit is suitable for accelerated blood coagulation of whole blood for subsequent autologous or allogeneic use. The blood collection unit includes an inside surface that has an activation site which accelerates coagulation by having a high roughness. A blood collection unit including an inside surface that has an activation site having a high roughness area, and an interior of the blood collection unit is prepared with a pressure of no more than 255 mBar, and preferably a pressure of no more than 130 mBar.
BLOOD SAMPLE OPTIMIZATION DEVICE
Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.
Systems and methods for parenterally procuring bodily-fluid samples with reduced contamination
The present invention is directed to the parenteral procurement of bodily-fluid samples. The present invention is also directed to systems and methods for parenterally procuring bodily-fluid samples with reduced contamination from dermally-residing microbes. In some embodiments, a bodily-fluid withdrawing system is used to withdraw bodily fluid from a patient for incubation in culture media in one or more sample vessels. Prior to withdrawing bodily fluid into the one or more sample vessels for incubation, an initial volume of withdrawn bodily fluid is placed in one or more pre-sample reservoirs and is not used for the incubation in culture media.

BLOOD SAMPLING DEVICES AND RELATED METHODS
A safety needle blood sampling device (100) is provided with a needle (108) having a multi-sampling Luer adaptor (MSLA) mounted over an end thereof. A housing (110) sized and shaped to receive a blood sampling vial is provided so that when a vacutainer is inserted, the MSLA is compressed to puncture the septum with one of the ends of the needle. A protective shield (104) is provided to cover the needle. A helical spring (106) is provided to move the protective shield over the needle in a used position. An activator (112) is further provided that is sized and shaped to activate the shield upon insertion of the vacutainer.
