Abstract
A differential pressure administration set having a tubular chamber, which has an inlet at its upper end connected to a liquid supply container. Below the inlet is a first chamber which receives liquid from the container. Near or at the bottom of the first chamber is an outlet supply line to provide the higher pressure liquid to the operating site. The first chamber also has a second outlet which feeds liquid to a second chamber below the first chamber. There is a second outlet supply line at the lower end of the second chamber, which provides the lower pressure liquid to the operating site. The differential pressure is produced by and corresponds to the difference in height between the levels of the fluids in the first and second chambers.
