Abstract: A device for delivering a liquid agent in doses, the device including a receptacle for storing the liquid agent and a propulsion mechanism for advancing a piston toward an outlet of the receptacle in order to expel a dose of the agent, wherein the propulsion mechanism permanently acts on the piston with a propulsive force, and wherein the device further includes a mechanism for releasably blocking a piston advance. The invention encompasses embodiments in the form of an infusion pump adapted to include the device for delivering and a controller for controlling at least the mechanism for releasably blocking.

Abstract: A device for administering a fluid product, including a container for the fluid product, an apparatus for dispensing the fluid product from the container, a metering apparatus for adjusting a product dose, and at least one temperature sensor disposed inside the container or near the fluid product. The present invention also encompasses a method for controlling the administration of a fluid product, wherein a metered quantity of a product dose, which is to be administered, is adjusted in accordance with the temperature of the fluid product and/or the temperature of the surroundings of the fluid product.

Abstract: The present invention provides a device for administering an injectable product in doses, the device including a casing, a container accommodated by the casing, a delivering appliance for delivering the product from the container, a drive for the delivering appliance, and a means for determining a malfunction of the device, wherein a vibrator motor is accommodated by the casing, the vibrator motor being triggered by the means for determining a malfunction such that it generates a vibrating alarm signal when a malfunction is determined.

Abstract: The invention pertains to devices for administering a liquid solution of an active substance, wherein the subject device has at least one associated temperature sensor.

Abstract: The invention relates to a process for the monitoring of the pressure of a product fluid to be administered in dosed amounts during an infusion or injection, which is dispensable from a container that is received in or formed by a housing, by advancement of a piston received in the container. The reaction force exerted by the piston onto the housing, which serves as a measure for the fluid pressure, is hereby measured and fed to a control for a drive of the piston. The control compares the measured reaction force with a predetermined reference force and controls the drive of the motor under consideration of the result of the comparison. The reference force is a nominal value for the reaction force and a direct nominal/actual comparison is carried out between the measured reaction force and its nominal value. The invention further relates to an apparatus which is especially suited for carrying out the process.
