A fluid handling device includes a receiving container with a piston arranged therein in a displaceable manner, such that the volume of a fluid receiving reservoir may be changed by a displacement of the piston. In addition, the fluid handling device includes an actuation mechanism configured to displace a carrier bearing upon actuation of the former. Finally, the fluid handling device includes a spring mechanism configured to transfer a force from the carrier bearing to the piston so as to effect, in response to displacement of the carrier bearing in a first direction, a displacement of the piston within the receiving container such that a volume of the fluid reservoir is increased.
