Y-set

Y-set,

a device composed of plastic components, used for delivering IV fluids through a primary IV line connected to a combination drip chamber filter section from which two separate plastic tubes lead to fluid sources. The Y-set also includes three clamps, one for the primary IV line and one for each of the two separate tubes. It is often used to transfuse blood cells used for any type of blood administration that must be diluted with saline solution to decrease their viscosity. In such a transfusion one of the tubes is connected to the container of blood cells. The other tube is connected to the container of saline solution. Compare component drip set, component syringe set, microaggregate recipient set, straight line blood set.

Y-set 

an intravenous administration unit with two separate spikes, each with a separate drip chamber and individual clamps for flow regulation; the fluids are intermingled in the tubing or sometimes in a third drip chamber. Y-sets may be used either for the rapid infusion of fluids or for dual administration, such as of blood and 0.9 per cent sodium chloride solution.
