摘要： An apparatus including a hollow body, an inlet fluidly coupled to the hollow body, a piston slidably engaged within the hollow body, and a filter module arranged within the hollow body between the inlet and piston. The piston and hollow body cooperatively generate a negative pressure, relative to ambient, within the hollow body during distal piston translation from a first position to a second position, thereby drawing a fluid, such as blood, through the filter module into the hollow body. The piston and hollow body cooperatively generate a positive pressure, relative to ambient, within the hollow body during piston translation from the second position to the first position to egress the filtered fluid from the hollow body. The filter module may include a filter housing, a filter medium disposed within the housing, and a body valve configured to seal an open distal face of the filter housing.

摘要翻译： 一种包括中空体的装置，与中空体流体连接的入口，可滑动地接合在中空体内的活塞和布置在入口和活塞之间的空心体内的过滤器模块。 在远端活塞从第一位置转换到第二位置期间，活塞和中空体在空心体内协同地产生相对于环境的负压，从而将诸如血液的流体通过过滤器模块拉入中空体。 在活塞从第二位置转换到第一位置时，活塞和中空体协调地产生相对于环境的正压力，从而从空心体排出过滤的流体。 过滤器模块可以包括过滤器壳体，设置在壳体内的过滤介质和构造成密封过滤器壳体的敞开的远侧面的主体阀。
