Abstract
A process and an apparatus for adjustment of a switchable, flow-limiting device for limited flow of liquids or gases employs a remote service device. The flow-limiting device and the service device are spatially separated and there is no bodily connection between the two. Energy necessary for adjustment of the flow-limiting device is transmitted from the service device into an infusion pump that contains the flow-limiting device. The flow-limiting device is a valve having three stable operating positional states. The valve can only be switched while energy is being transmitted from the service device.
