Assemblies and methods for fluid delivery (e.g., solutions, solutions comprising suspensions of cells, fibrinogen, thrombin, and the like), such as those, for example, configured to deliver a fluid to a body of a person. The assemblies comprise a first inlet channel (42)； a second inlet channel (46)； a first outlet channel (54)； a second outlet channel (58)； a first pump (66, 78)； a second pump (66, 74)； and a body (14) configured to be coupled to a first container and a second container such that an interior of the first container is in fluid communication with the first inlet channel, and such that an interior of the second container is in fluid communication with the second inlet channel； where if a first container with a fluid and a second container with a fluid, are coupled to the body, the assembly is configured upon at least one actuation to successively pump fluid from the first container, through the first inlet channel, and out the first outlet channel； and fluid from the second container, through the second inlet channel, and out the second outlet channel.
