A device for administering a fluid product includes a first housing part with a receiver for the product, a second housing part detachably connectable to the first housing part, a piston rod held such that it can be displaced for the exertion of an emptying movement, an actuatable or releasable drive element for the piston rod, a coupling element including a coupling input element that couples the drive element to the piston rod in a coupling engagement, transmits a driving force of the drive element to the piston rod, and triggers the emptying movement, and a decoupling element displaceably connected to the second housing part and coupled to the first housing part such that it is displaced, by a movement of the housing parts in relation to each other when the housing parts are separated into a decoupling position wherein the piston rod is decoupled from the coupling input element.

Device for the dosed administration of a fluid product, adapted for the replacement of a container

A device for administering a fluid product, the device including a first housing part provided with a receiver for the product, a second housing part detachably connectable to the first housing part, a piston rod held such that it can be displaced for the exertion of an emptying movement, an actuatable or releasable drive element for the piston rod, a coupling element including a coupling input element that couples the drive element to the piston rod in a coupling engagement, transmits a driving force of the drive element to the piston rod, and triggers the emptying movement, and a decoupling element displaceably connected to the second housing part and coupled to the first housing part such that it is displaced, by a movement of the housing parts in relation to each other when the housing parts are separated into a decoupling position wherein the piston rod is decoupled from the coupling input element.

An injection device including at least one sensor for detecting an operating process of the injection device, an electronic circuit connected to the sensor for establishing the beginning and elapsed time of a service life, based on one or more sensor signals, and an output device connected to the circuit for providing a signal indicating the end of the service life. The invention encompasses a method for determining a service life of an injection device, wherein the beginning of the service life is established by one or more sensors for detecting an operating process of the device, a signal is generated which signals the end of the service life, and at least one of an optical, acoustic or tactile output device is associated with the injection device for providing a signal which indicates the end of the service life.

Service life timer for a device for administering a product in doses

A device for administering a fluid product including a housing, a conveying device for the product, a coupling element provided for the drive of the conveying device and which can be rotated about a rotational axis, a first blocking element connected in a rotationally secure manner to the coupling element, a second blocking element detachably engageable with the first blocking element thereby preventing a rotational movement thereof in the drive direction and enabling said rotational movement to take place in the counter dosing direction, a torsion spring connected to the coupling element such that it is stressed by the rotational movement when the blocking elements are engaged in a blocked position and drives the coupling element in a rotary manner after the blocking position is released, and a release element coupled to at least one of the blocking elements such that a release movement of the release element displaces at least one of the blocking elements from the blocked position, the release element also forming a dosing element used to control a product dose.
