Abstract

A blood sequestration device includes an inlet path, an outlet path, a sequestration chamber, and a sampling channel. The sequestration chamber is connected with the inlet path by a junction and is configured to receive a first portion of blood through the inlet path. The sequestration chamber has a vent that allows air to be displaced by the first portion of blood, the junction being configured to inhibit a return to the inlet path of any of the first portion of blood received by the sequestration chamber. The sampling channel is connected between the inlet path and the outlet path, and configured to convey subsequent amounts of blood between the inlet path and the outlet path after the first amount of blood is received by the sequestration chamber.
