Abstract
A fluid dispenser pump has a fluid reservoir, and a pump that has a pump chamber with a piston that moves within the pump chamber to pump fluids out a dispensing orifice. The pump has a priming air channel that fluidly connects the reservoir to the pump chamber and is separate from the fluid channel that connects the reservoir to the pump chamber. With non-sterile fluids, such as medicine, the air channel cannot displace the air to the exterior of the dispenser, but must displace it to the reservoir where it assists in priming the fluid channel.
