    Abstract: An injection device for delivering equal doses of a fluid contained in a reservoir, the device having a housing, and an arming mechanism and a dose delivery mechanism arranged therein, the housing coupled to an enclosure for the reservoir. The arming mechanism includes an axially non-displaceable and rotatable setting sleeve. The setting sleeve is coupled with a spring strained by the rotation of the setting sleeve during arming of the device. The dose delivery mechanism includes a screw ring and a non-rotatable and axially displaceable piston rod within the setting sleeve. The piston rod cooperates with the screw ring so that during arming, the screw ring and the piston rod are immobilized, and during delivery of each dose the piston rod is displaced along the housing due to unwinding of the spring and rotation of the screw ring, the displacement of the piston rod causing the fluid to be discharged from the reservoir.

  • Patent number: 10357616
    Abstract: An injection device with a dose delivering mechanism being adapted to provide a non-visual, e.g. audible and/or tactile, feedback signal when a set dose has been at least substantially injected. A first and a second part of the injection device are adapted to perform a relative rotational movement with respect to each other. The relative rotational movement causes at least two parts of the injection device to abut or engage, and this abutment or engagement causes the non-visual feedback signal to be generated. A very distinct and precise feedback is provided as compared to prior art axial solutions because the generation of the feedback signal is initiated by the relative rotational movement. Feedback signal may be generated by a change in a rotational velocity of at least one part, e.g. by changing the pitch of a threaded portion or by engaging a non-rotating part and a rotating part, thereby causing the non-rotating part to start rotating.

  • Patent number: 10265480
    Abstract: A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.

  • Patent number: 10213560
    Abstract: An injection device includes a housing, a dose setting member being operable in a first direction to set a desired dose to be dispensed, and a piston rod being adapted to cooperate with a piston so as to cause a set dose to be injected from a cartridge. Further, a first part and a second part of the injection device are provided, which are adapted to perform a relative rotational movement with respect to each other during dispensing of a dose, and which are adapted to provide a non-visual feedback signal to a user only at the end of dispensing of a set dose. The dose setting member is further operable in a second direction which is opposite to the first direction to cancel a set dose. A third part is movable between a dose setting or cancelling position and a dose dispensing position relative to the first part and/or the second part, which third part contacts the first part and/or the second part in its dose setting or cancelling position or in its dose dispensing position.

  • Patent number: 10195358
    Abstract: The piston rod arrangement is in an assembled state before use and comprises a piston rod, a bung, which is intended to be driven by the piston rod, a body member, and a drive member. The piston rod is threadedly engaged with the body member, and the drive member is threadedly engaged with the piston rod and movable relative to the body member. A mechanism is provided defining unit steps of movement of the drive member and corresponding unit steps of movement of the piston rod. The piston rod is arranged in contact with the bung or at a distance from the bung that is less than a distance of one corresponding unit step of movement. When the piston rod, the bung and the drive member are assembled in the body member, the piston rod is advanced with respect to the body member towards the bung, until the piston rod is stopped by the bung. The drive member is rotated until the piston rod begins to advance again and the drive member is then stopped, and the piston rod is fixed at or near the position obtained.
