ABSTRACT:
An injection site designed for use with a needleless syringe includes a housing placed in an infusion line and an inlet for engaging the syringe and conveying a fluid to be mixed with the infusate to the interior of the housing. A liner within the housing controls flow of fluid through the inlet by sealing the inlet when the pressure in the housing is equal to or exceeds the pressure in the syringe. The housing is made of two parts, each of which includes a flange. When assembled, the spaced flanges are on opposite ends of the liner, which is not directly attached to the housing, to limit movement of the liner to maintain its position in the housing.
