A multiple fluid pulse dispenser comprising a plurality of interconnected fluid reservoirs defined by mating, oppositely directed concavities at least one of which mating concavity is formed from an invertable, preferrably permanently deformable blister. The reservoirs are in fluid communication with an outlet through which the contents of the reservoirs may be dispensed. A preferred embodiment permits fluid to flow through a reservoir after it has been discharged to allow random activation of the individual reservoirs.

A multiple fluid pulse dispenser for introducing predetermined amounts of a biologically active agent into an animal comprising, in combination: (a) a first member having a plurality of spaced apart concavities formed on one surface, (b) a second member comprising a plurality of spaced apart permanently invertible blisters, said first and second members being sealed together with the blisters overlaying the concavities so as to provide a plurality of fluid receiving reservoirs, the blister configuration being selected such that, on inversion, the inverted blister will displace substantially all of the fluid contents of its reservoir, and (c) fluid communication means connecting said reservoirs to a common outlet means through which the fluid contents of said reservoirs may be dispensed upon inversion of a blister into its associated concavity.
