1. A fluid control valve for use in a fluid delivery system for delivering fluid to a patient, the fluid control valve comprising:
a valve body defining an internal chamber;
a first inlet port for receiving a first inlet tube, wherein the first inlet tube defines a first inlet lumen in fluid communication with the internal chamber, and wherein the first inlet port is in axial alignment with the internal chamber;
a second inlet port for receiving a second inlet tube, wherein the second inlet tube defines a second inlet lumen in fluid communication with the internal chamber, and wherein the second inlet port is in axial alignment with the internal chamber;
an outlet port; and
a sliding valve member disposed in the internal chamber and configured to slide along an axis in the internal chamber between the first inlet port and the second inlet port, the sliding valve member comprising a first sealing end and a second sealing end;
wherein the sliding valve member is positionable in a first operating state, a second operating state, and a third operating state based on a fluid flow differential between a first fluid in the first inlet lumen and a second fluid in the second inlet lumen; and
wherein the sliding valve member and the valve body define at least one channel extending between the first sealing end and the second sealing end, wherein the at least one channel provides fluid communication between the second inlet lumen and the outlet port in the first operating state, the at least one channel provides fluid communication between the first inlet lumen and the outlet port in the second operating state, and the at least one channel provides fluid communication between the first inlet lumen, the second inlet lumen, and the outlet port in the third operating state;
wherein the sliding valve member comprises at least one mixing feature associated with a body of the sliding valve member and configured to provide mixing at a confluence point of the first fluid from the first inlet lumen and the second fluid from the second inlet lumen.
