Syringe type fluid diversion mechanism for collecting body fluid

摘要

A bodily fluid sequestration device (100), the device comprising a housing (101) including a port (105) and defining an inner volume (111), the port configured to receive a flow of bodily fluids therethrough, the port configured to be placed in fluid communication with a first flow path (181) and a second flow path (191); and a valve disposed in the first flow path and configured to form a substantially fluid tight seal with a set of walls defining the first flow path, the valve being operative to move from a closed configuration to an open configuration in response to a pressure differential to allow an initial volume of bodily fluid to be transferred from the port and into the first flow path, the valve being further operative to return to the closed configuration in response to equalization of the pressure differential to sequester the initial volume of bodily fluid from the second flow path, after the valve is returned to the closed configuration, the second flow path configured to receive a subsequent volume of bodily fluid with reduced contamination due to the sequestration of the initial volume of bodily fluid.
