The present disclosure describes flow stagnation control components that allow improved flow control in systems including injection members, while also limiting the creation of regions of little to no flow in the vasculature, resulting in low flow zones or dead zones. The flow stagnation control components can be formed as an imposed minimum conductance component or a controlled flow partitioning system.本發明描述流動淤塞控制組件,其等允許改良包含注入構件之系統中之流動控制,同時亦限制在脈管中少流或無流區之產生,從而導致低流區域或死區域。該等流動淤塞控制組件可形成為一外加最小傳導組件或一控制分流系統。200‧‧‧體外環路206‧‧‧泵系統208‧‧‧熱交換器210‧‧‧注入器構件212‧‧‧脈管注入點214‧‧‧血液
