  • Publication number: 20220362458
    Abstract: Needle insertion mechanisms include a housing and a needle holder, the needle holder being linearly guided by the housing to be moved along the needle-axis. A slider linearly guided by the housing and transversally moveable with respect to the needle-axis from a first to a second slider position. The needle holder is operatively coupled to the slider when the slider is in the first position, thereby retaining the needle holder in a retracted position against the bias of a spring acting on the needle holder. In the second position the slider is decoupled from the needle holder and the holder is moved into an inserted position by the spring. A blocking member arranged between the slider and the housing blocking movement of the slider into the second position, is moved by an active drive thereby unblocking the movement of the slider and subsequently moving the slider to the second position.

  • Publication number: 20220241497
    Abstract: An assembly for a cartridge needle insertion mechanism includes a housing, a cartridge needle defining a cartridge needle axis and a cartridge closed by a septum. A cartridge needle slider is linearly guided by the housing along an insertion axis to be moved by a driver from a first position, where the cartridge needle is not penetrating the septum, to a second position where the cartridge needle penetrates the septum of the cartridge. A cartridge needle holder holding the cartridge needle is operatively coupled with the cartridge needle slider to be moved with the cartridge needle slider from the first to the second position. The assembly includes a compliant coupling between the cartridge needle holder and the cartridge needle slider configured to facilitate movement of the cartridge needle holder with respect to the slider when moved into the second position, thereby compensating for needle penetration forces.

  • Publication number: 20220226582
    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.

  • Publication number: 20210353862
    Abstract: Modular syringe holders receive small-volume product containers for use in injection devices configured for nominally large-volume product containers, and include an adapter and an adapter holder configured for insertion in such injection devices. The adapter includes a hollow-cylindrical, rigid adapter body and a radially deflectable support element for a receiving a syringe shoulder of a pre-filled syringe. During receipt of the pre-filled syringe, the support element undergoes a radial deflection by a needle protection cap of the pre-filled syringe. The adapter holder is configured to receive the adapter, and a holding portion of the adapter holder blocks the support element against radial deflection in a holding position in an engagement with the syringe shoulder. With the adapter and pre-filled syringe received in the adapter holder, a flexible shoulder-support element diverts axial forces of the shoulder of the pre-filled syringe and is secured by the adapter holder against lateral deflection.

  • Publication number: 20210146059
    Abstract: Dosing device for an administration device with a limiting mechanism containing: a dosing sleeve with a first stop and a stop wheel with a second stop means adapted to continually and proportionally follow a movement of the dosing sleeve during dosing movements. During an ejection movement, there is no relative movement between dosing sleeve and stop wheel. The first stop and the second stop each describe a path curve by their movements such that the two path curves intersect in one point and the stops contact one another and tilt the stop wheel, thereby blocking the dosing movement of the dosing sleeve. The stop wheel comprises first and third sloped surfaces that may form first and second gear guidances with a clutch thereby returning the stop wheel to a non-tilted position during up or down dosing movements when the stops do not contact another.

  • Publication number: 20210138151
    Abstract: A needle insertion and retraction mechanism for a medication delivery device includes a housing and a needle carrier holding a needle guided by the housing and moved along a needle axis. A first spring member is adapted to move the carrier in an insertion direction. A second spring member is adapted to retract the carrier in a retraction direction, opposite the insertion direction. A control element, linearly guided by the housing, moves transversely to the needle axis from a starting position, via a needle insertion release position, to a needle retraction release position. When the control element is in its starting position, the control element is coupled to the carrier to prevent the carrier from moving in the insertion direction. When the control element is in the release position, the control element is decoupled from the carrier and the first spring member drives the carrier in the needle insertion direction.

  • Publication number: 20210001048
    Abstract: An assembly for an injection or infusion device includes i) a cartridge being closed by a septum and the surface of the septum being sterile and covered by a first continuous flexible strip, and ii) a fluid path unit comprising a cartridge holder and a fluid path compartment comprising a needle in an interior, the needle is configured to penetrate the septum of the cartridge through a passage in the fluid path compartment. The passage is closed by a second continuous flexible strip keeping the interior of the fluid path compartment in a sterile condition. The cartridge is inserted into the cartridge holder aligning the septum with the passage and sandwiching both strips between the septum and the fluid path compartment. Both strips may be simultaneously removable from the cartridge and fluid path compartment thereby, establishing a sterile connection between the septum and the interior of the fluid path compartment.

  • Publication number: 20200405951
    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.
