Abstract

Fluid access devices include a machine-side hydraulic circuit and a patient-side hydraulic circuit, and are configurable between a connected state and at least one disconnected state. In the connected state, fluid flows between the machine-side hydraulic circuit and the patient-side hydraulic circuit. In the disconnected state, fluid does not flow between the machine-side hydraulic circuit and the patient-side hydraulic circuit. In some disconnected states, fluid recirculates through at least one of the machine-side hydraulic circuit or the patient-side hydraulic circuit in the disconnected state.
