Abstract: A product container receptacle and an autoinjector may include: a syringe holder for accommodating a pre-filled, ready-to-use syringe defining a longitudinal axis, with a cylindrical product container that narrows at its distal end via a shoulder, and a needle protection cap. The syringe holder includes a distally, coaxially arranged guide sleeve on the inner wall of which a blocking surface is formed; an insert having a snap arm, which is radially deflectable with respect to the longitudinal axis from a relaxed position and has a snap hook; and a detachable device cap in which the insert is connectably accommodated. The insert is movable relative to the device cap from a first latching position to a second latching position, and the connection of the device cap to the insert, in at least the second latching position, is configured to latch and form-fit with respect to tensile forces.

Abstract: An injection device configured for attachment to the skin of a patient includes a housing and a skin adhesive layer attached to an external surface of the housing for attaching the injection device to the skin of a patient. A release liner covering the skin adhesive layer prevents the injection device from attaching to the skin. A film with one end connected to a surface inside of the housing forms a removable sterile barrier and the other end connected to an external surface of the release liner without contacting the skin adhesive layer. The housing, skin adhesive layer and release liner each include a notch defining a passage for the film so that the second end of the film can extend from the interior to the exterior of the housing.

The detachable needle protection cap comprises a housing and at least two shell parts which can be attached to an outer surface of the housing, the shell parts being fastened to an outer surface of the housing. The shell parts can mutually prevent removal of the shell parts.

Abstract: An injection device comprising a cap for removing a needle protection cap from a product container, and a method for assembling an injection device. The cap comprises an engaging element for removing the needle protection cap from the product container when the cap is removed from the injection device. The engaging element can be deformed in such a way that the engaging element can be moved from a distanced position, in which the engaging element is radially distanced from the needle protection cap, into an engagement position, in which the engaging element engages with the needle protection cap, with the engaging element being deformed when the cap is removed.

Abstract: An autoinjector comprises a housing, a product container, a displaceable needle protection sleeve, a plunger rod displaceable by a preloaded discharge spring, a dose setting element with at least two different rotational positions relative to the housing, and a dosing sleeve. The dosing sleeve or the plunger rod has a dose selection stop, and the other has at least one dosing stop. By rotating the dose setting element, the dosing sleeve or the plunger rod is rotated relative to the other. Upon displacement of the needle protection sleeve, the spring displaces the plunger rod, whereby, if the dose setting element is in the first rotational position, the dose selection stop and the first dosing stop strikes against each other, and, if the dose setting element is in the second rotational position, one of the dose selection stop and the first dosing stop is or can be moved past the other.

Abstract: An injection device configured for attachment to the skin of a patient using an adhesive layer includes a release liner covering the adhesive layer thereby preventing skin attachment. The release liner comprises a sheet of material where a first surface contacts the adhesive layer, and an aperture defining a passage for a film connected to a first sterile barrier film located within the injection device. An end of the film is connected to a second surface of the sheet of material that is opposite to the first surface, and the release liner is covered by a strengthening sheet connected to the second surface and covering the aperture and the end of the film.

Abstract: Needle insertion mechanisms for an injection device include a housing, a needle holder holding a needle, a slider moveable from a first position retaining the needle holder in a retracted position towards a second position allowing movement of the needle holder to an inserted position. An intermediate member positioned between the needle holder and the slider is moveable from a blocked position to a release position releasing the needle holder for movement to the inserted position. A biased gearing between the intermediate member and the needle holder biases the intermediate member towards the release position. A lock between the intermediate member and the slider is configured to lock the intermediate member in the blocked position against the bias of the gearing. Movement of the slider towards the second position unlocks the lock and the biased gearing moves the intermediate member into the release position thereby releasing the needle holder.

Abstract: A dosing device for an injection device, the dosing device including an actuating element for adjusting and/or dispensing a dose from the injection device, a thrust element for generating a forward movement for discharging a dose and a coupling to which the actuating element and the thrust element are coupled such that a rotational movement of the actuating element is transmitted directly to the thrust element and an axial movement of the actuating element is different than an axial movement of the thrust element.

Abstract: An injection device for administering a substance, including a housing, a plunger rod which can be moved relative to the housing, at least one retaining element associated with the rod to hold the rod relative to the housing, and a displaceable locking sleeve which can be displaced relative to the housing from one position in which the sleeve holds the at least one retaining element in a retaining position to a second position in which the at least one retaining element is released.

Abstract: An autoinjector for dispensing a liquid product includes a housing; a product container arranged in the housing, particularly, a syringe comprising a displaceable piston; a drive member; a first spring which acts on the drive member and the piston to dispense the product from the container; signal element releasably axially coupled with the drive member so that the signal element is transported in the dispensing direction as said drive member is displaced; and a second spring, which exerts a spring force on the signal element against the dispensing direction and is tensioned as the signal element is transported in the dispensing direction. When the signal element is released or detached from the axial coupling, the second spring causes the signal element to accelerate opposite the dispensing direction and strike against a signal stop and generate an acoustic and/or tactile signal.
