Abstract
A check valve assembly is configured to couple to a first container that retains a first fluid and a second container that retains a second fluid. The check valve includes a fluid inlet housing including a first fluid inlet port defining a first fluid inlet channel, and a second fluid inlet port defining a second fluid inlet channel. A fluid outlet housing is coupled to the fluid inlet housing. The fluid outlet housing includes a fluid outlet port defining a fluid outlet channel. A first diaphragm is seated over the first fluid inlet channel. At least a portion of the first diaphragm is configured to unseat over the first fluid inlet channel to allow the first fluid to pass from the first fluid inlet channel into the fluid outlet channel. A second diaphragm is seated over the second fluid inlet channel. At least a portion of the second diaphragm is configured to unseat over the first fluid inlet channel to allow the second fluid to pass from the second fluid inlet channel into the fluid outlet channel.
