MULTI-CHAMBER BLOOD COLLECTION DEVICE AND RELATED SYSTEMS AND METHODS

Abstract:

A blood collection device may include a tubular container, which may include a closed end and an open end opposite the closed end. The blood collection device may include a plug sealing the open end and a partition within the tubular container. The partition may separate the tubular container into a first chamber and a second chamber. The first chamber and the second chamber may be evacuated such that a pressure within the first chamber and a pressure within the second chamber are lower than ambient pressure and equal to each other. In response to blood being drawn into the first chamber, the pressure within the first chamber may increase, and the partition may slide towards the closed end such that a size of the first chamber increases and a size of the second chamber decreases.
