  • Patent number: 11278676
    Abstract: An injection device comprising a housing having a longitudinal axis, a dose selector (16) capable of being rotated about said longitudinal axis with respect to said housing by a user to set a dose of medicament to be ejected from the injection device and a spring (20) capable of storing energy necessary for ejecting the dose of medicament from the injection device. The spring is coupled to the dose selector such that a charging force can be transferred from the dose selector to the spring to increase the energy stored by the spring. The injection device further comprises a ratchet arrangement (25) moveable between an engaged state in which the spring is limited from unwinding from a currently selected dose and a disengaged state in which the spring is able to unwind and a drive assembly including a plunger element (23) capable of providing an axial force for ejecting a dose of medicament from the injection device.

  • Patent number: 10973988
    Abstract: In an elongated casing, an active agent container connected to an injection needle can be shifted axially by a spring force. Auto-injectors which are sold or distributed filled and with the springs tensed have to be provided with a needle protecting cap to ensure the sterility of the injection needle. When such a needle protecting cap is removed as preparation for using the auto-injector, a tensile force can be exerted on the active agent container. Therefore, the active agent container comprising the injection needle must be prevented from being undesirably pulled forwards. At least one latching tongue prevents the active agent container from being prematurely shifted with respect to the casing, by abutting a flange arranged on a sliding sleeve which accommodates the active agent container. When the auto-injector is placed onto a person's skin, a needle protecting tube is shifted into the casing, forcing the latching tongue away from the flange and, thus, freeing the travel path for needle movement.

A compressed, elastic power element (18) disposed in the power-pack module (12) is coupled to a plunger (30) movably disposed in a drug reservoir (22) in the drug-cartridge module (14). An injection needle (24) at the distal end of the drug reservoir (22) is oriented orthogonal to the drug reservoir (22) and generally toward a skin-contact surface (28) extending parallel to the longitudinal drug-reservoir axis (22A). The power element (18) is configured to displace the plunger (20) distally into the drug reservoir (22) and to move the injection needle (24) toward the skin-contact surface (28) when the power element (18) expands distally along the drug-reservoir axis (22A).

  • Patent number: 10828421
    Abstract: A device for drug injection has a cartridge, which in turn has a reservoir and a fluid path. The fluid path carries a fluid for injection from the reservoir to the place where the patient is to be injected. The fluid path comprises a needle, and the fluid path is kept sterile. A drive chain extends the needle to the injection point, but is only mechanically connected to the fluid path to operate the needle, the mechanical connection being such as to operate the needle while maintaining the fluid path sterility.

  • Patent number: 10806865
    Abstract: An injector apparatus includes a housing (101, 102) for a cartridge or syringe, a plunger (40) for cooperating in use with the cartridge or syringe to express successive doses, a dose setting arrangement (16, 20) to select a dose volume, and a drive mechanism (22, 24) releasable to advance the plunger in respective predetermined increments of magnitude to express the successive doses. The drive mechanism includes a drive spring (22) for imparting movement directly or indirectly to the plunger (40), and the dose setting arrangement includes a dose setting element (16) moveable in a dose setting routine to define a magnitude of an increment of movement of the plunger for a given dose. The drive mechanism further includes a clutch arrangement (56) operable during the dose setting routine to inhibit forward movement of the plunger and/or to isolate the dose setting element from the force of the drive spring.

  • Patent number: 10765809
    Abstract: A reloadable auto injector has a needle insertion driver to be re-activated upon reloading. A syringe is movably positioned in a housing between a first position and a second position. A plunger rod is locked to a plunger rod tube by a deflectable locking member. A syringe driver applies a force to the syringe to move the syringe together with plunger rod tube, plunger rod and plunger rod driver from the first position to the second position. In the second position, the locking member is unlocked and releases the plunger rod to thereby activate the plunger rod driver to advance the plunger rod in the syringe for delivering of medicament. A reload handle is connected to the syringe assembly so that user operation of the reload handle retracts the syringe to the first position and simultaneously reloads the syringe driver for delivering a further dose of medicament.

  • Patent number: 10758668
    Abstract: Embodiments provide apparatus and methods for delivering liquid form medication within the body wherein the medication is stored in solid form and then mixed with a liquid in an apparatus implanted within the body. One embodiment provides an implantable apparatus for in vivo delivery of medication comprising a housing including a reservoir, a store of solid form medication (SSM) and a pump. An SSM element is added to the reservoir along with fluid to form a medication solution comprising at least one drug. The medication solution is then delivered to a delivery site using a pumping means to pump solution from the reservoir through a delivery member such as catheter to a delivery site. Embodiments of the invention are particularly useful for delivering medication to a patient to treat a medical condition over an extended period of time without requiring the patient to take external medication.
