ABSTRACT:
A system for sequential tubular administration of first and second fluids including a first reservoir to contain a first solution, e.g., a solution of medication; a second reservoir having less capacity than the volume of solution in the first reservoir with an overflow chamber. The two reservoirs are in communication with each other, and both are provided with valved solution discharge lines, the entrance to which is provided with a ball float valve. The two discharge lines meet at a wye connection having an infusion feed assembly at an outer free end of same. With a first solution in the first reservoir and with both reservoirs closed to the atmosphere, second solution, e.g., I.V. solution may be fed into the second reservoir which displaces air therefrom into the first reservoir to assist in feeding solution from the first reservoir. Just prior to completion of discharge of solution from the first reservoir, solution from the second reservoir overflows into the overflow chamber, opens a ball float valve and initiates administration of the second solution upon completion of administration of the first solution. Both solution discharge lines are adjustable for flow rate and provided with off-on connections and check valves. Automatic switching to administration of second solution upon completion of administration of the first solution precludes the administration of air into the line and prevents blockage of the infusion feed assembly by clotting of blood, etc. therein.
