Claim 2:
3. The disposable IV set of claim 2, further comprising:
a spring disposed within the lower end of the y-port housing opposite the syringe port and the upper end of the y-port housing,
wherein the spring is configured to engage the sliding valve to cause the sliding valve to be positioned in the first position when a syringe is not engaged with the syringe port, and to compress when the sliding valve is moved toward the lower end responsive to a coupling of a syringe with the syringe port,
wherein the coupling of the syringe with the syringe port causes the sliding valve to be compressed against the spring to move the sliding valve to the second position whereby the second fluid pathway is formed, and a decoupling of the syringe from the syringe port causes the sliding valve to retract due to extension of the spring to move to the first position whereby the first fluid pathway is formed.
