Blood sampling system for improving draw success and reducing hemolysis

摘要

An intravenous system can be optimized to improve blood draw success and reduce hemolysis within the blood sample. Multiple optimizations can be made to an intravenous system, such as a peripheral intravenous catheter, to enhance the system's ability to provide blood samples having sufficient quality for many different tests. These optimizations can include features which enable an intravenous system, such as a peripheral intravenous catheter, to continue to perform efficiently when used to obtain blood samples even after the system has been placed within the patient's vasculature for a substantial duration of time. Also, these optimizations can include features for optimizing the fluid path and flow characteristics during blood withdrawal to minimize the amount of hemolysis that may be caused during withdrawal. Further, these optimizations can include features for integrating blood acquisition and dispense capabilities within the system.
