Abstract: Metered dispensing of a microfluidic amount of fluid from a reservoir comprises a pressure device which applies a discharge pressure for fluid ejection via a discharge line through a valve arrangement. The valve device has a first valve with a minimum closing time and a second valve with a minimum opening time. A control device provides control signals for operation for metered dispensing of the amount of fluid as follows: a shortened minimum opening time for freeing the discharge line for the fluid flow, which time is shorter than the minimum opening time of the second valve; and a shortened minimum closing time for closing the discharge line for the fluid flow, which time is shorter than the minimum closing time of the first valve. Furthermore, a hand-held device for locally piercing human or animal skin is disclosed.
