APPARATUS FOR INTRAVENOUS ADMINISTRATION OF A FLUID FROM A DUAL-CHAMBER FLASK HAVING AN INTERNAL UPSET-TABLE SEPTUM NORMALLY SEPARATING TWO AXIALLY-IN-LINE CHAMBERS AND HAVING A PIERCEABLE END STOPPER

摘要

A standard drip meter assembly of the type having an upstanding stopper piercer with both an air inlet and a passage for the fluid into the drip meter, is supplemented by a solid air-inletting spike with a socket fitting over the stopper piercer and having a long shank that terminates in a non-coring piercing end. Passages adjacent the socket communicate with the air inlet and the passage in the drip meter stopper piercer. The supplemental spike is long enough to upset the septum after it pierces the stopper of a dual-chamber flask. An advantage is that inletting air then enters near the bottom of the flask to help agitate the fluid. An initiating pumping device for hand operation is provided adjacent the outlet of the drip meter.
