A product dispensing apparatus including a reservoir module, a dosing module and a dose setting member. The reservoir module includes a front casing section, a block, a first connector, a piston, and a piston rod moveable in a dispensing movement and against the dispensing movement, and including a return block engageable with the block, wherein engagement between the block and the return block prevents the piston rod from moving against the dispensing movement. The dosing module includes a rear casing section, including a second connector which is engageable with the first connector to form a detachable connection between the reservoir module and the dosing module, and a dosing and drive device. The dose setting member engages the piston rod such that it is moveable together with and in the same direction as the piston rod during the dispensing movement and is moveable relative to the piston rod against the dispensing movement.

Reservoir module comprising a piston rod

An administering apparatus having a casing including a reservoir for a product to be administered, a piston which can be shifted in the reservoir in an advancing direction towards a reservoir outlet to administer the product, a piston rod, a dosing and drive element for performing a dosing movement for selecting a product dose and a delivery movement for delivering the product dose, and a dose setting member which is moved in the advancing direction during the delivery movement, and which engages the piston rod and the casing such that it can only be moved in the advancing direction jointly with the piston rod and is moved counter to the advancing direction relative to the piston rod during the dosing movement.

Administering apparatus comprising a dosing device

An administering apparatus for administering a fluid product, including a casing, a reservoir for the product, a driven device which acts on the product contained in the reservoir to deliver the product, and a drive device which acts on the driven device and performs a delivery stroke in a drive direction from a delivery position up to a delivery stopper to deliver a product dosage to be administered, wherein a priming stopper is provided for the drive device and limits a priming stroke of the drive device, which serves to bleed, in the drive direction, wherein the priming stroke is axially shorter than a maximum delivery stroke, and wherein the drive device can be moved in the drive direction from a priming position up to the priming stopper and transversely to the drive direction as far as the delivery position.

Administration device comprising a priming function

An injection device for injecting selectable amounts of a substance includes an activating mechanism including an axially moveable operating button which can rotated in a resting position only, a tubular drive element non-rotatably connected to the operating button, an axially fixed and non-rotatable guiding element, and an axially moveable driven member held non-rotatably in the device. A rotational grid is operationally between rotatable and non-rotatable components of the injection device such that the operating button can be moved two rotational directions when in the resting position whereby a selected amount of the substance to be injected can be selectively varied. For example, a dosage inadvertently selected too large by rotating the operating button too far in one direction can, in accordance with the present invention, be reduced by rotating the operating button in the opposite direction. In some embodiments, the rotational grid is adapted to produce a clicking sound when the operating button is rotated.

Injection device

An administering apparatus for delivering a dosage of product including a casing with a reservoir for the product, a piston within the reservoir to deliver the product, a piston rod for engaging the piston, a drive device for driving the piston rod, and a dosage setting member mechanically engaging the piston rod and a stopper for the dosage setting member. The casing includes a front casing section containing a reservoir for the product and a rear casing section detachably connected to the front casing section. The front casing section is connected to or forms a first latching element, and the rear casing section is connected to or forms a second latching element. The latching elements are in latching engagement when the casing sections are connected. The casing sections may be axially fixed to one another by the latching engagement. The casing sections may alternately be fixed to one another, secured against rotating, with respect to a rotational movement about a longitudinal axis of the casing sections parallel to the advancing direction, by the latching engagement. The administering apparatus further includes a latching block coupled to the drive element such that the latching engagement can only be released in a releasing position of the drive element.

Latching block for connecting casing sections of an administering apparatus

An administering apparatus with a dosage display, including a casing, a reservoir for a fluid product, a driven device which acts on the product, a dosing means for selecting a product dosage to be delivered which includes a dosage scale including a number of dosage marks axially spaced from each other, and a drive device coupled to the driven device for driving the driven device, the drive device performing a delivery stroke from an initial position, in a drive direction, to a delivery stopper, the length of the delivery stroke counter to the drive direction being limited by selecting the product dosage using the dosing means, wherein the casing is transparent at least in an area overlapping the dosage scale, and wherein the drive device forms an indicator to the dosage scale in order to indicate the initial position of the drive device.
