Abstract: An improved measuring chamber for use in an intravenous feeding set is defined by a rigid transparent plastic chamber and includes an injection site formed in a side wall of the chamber. With the injection site in this position, the tendency of dust to collect on the injection site is significantly reduced. Moreover, adding medication to the measuring chamber is easier because the attendant need not reach so high. Finally, if the injection site is located below the liquid level of parenteral fluid in the chamber, homogeneous mixing of the parenteral fluid and the medication added thereto can be accomplished by simply pumping the plunger of the hypodermic syringe used to add the medication to the chamber.
