Abstract: The blood collection set includes an IV needle assembly, a length of flexible plastic tubing extending from the IV needle assembly and a non-patient needle assembly. The set is formed with a venting mechanism that permits an outflow of air, while blocking an outflow of blood or other fluids. Thus, the venting mechanism enables air that had existed in interior portions of the blood collection set to be vented allowing for greater flash visualization on venous entry, and avoids the need to employ a discard tube.

Abstract: The invention is a self-venting blood collection needle assembly for the extraction of at least one fluid sample into an evacuated container for laboratory testing, this blood collection needle assembly providing a clear or translucent flashback chamber for blood to flow into, for visualization by the user to confirm successful vein entry. The self-venting mechanism permits escape of air during use, and which, typically, also prevents an outflow of fluid, such as blood. Thus, air under venous pressure will be allowed to escape from the blood collection needle assembly until blood reaches the venting mechanism.

Abstract: A bioreactor system comprising a multi-well platform including an array of bioreactor units. The bioreactor system comprises a perfusion unit and a fluid source unit fluidly interconnected by a pumping unit. The perfusion unit comprises a multi-well plate including a plurality of main chambers configured to house or contain a cell culture and in each bioreactor unit an independent cell study or experiment may be performed.
