Abstract
A cassette for use with an I.V. infusion pump has a housing with a first inlet, a second inlet, an outlet, and a port to the I.V. infusion pump. A valve body is positioned within the housing to selectively establish fluid communication from the first inlet to the port, or from the second inlet to the port, or from the port to the outlet. Movement of the valve body within the housing into yet another position allows for the free flow of fluid directly between the first inlet or the second inlet and the outlet.
