  • Patent number: 10398840
    Abstract: A dispensing device which disperses medicate through a needle across a zone within a body. The device includes a needle which is, during use, becomes encapsulated within a tubular needle-receiving member, a reservoir in fluid communication with the needle, positioned within the housing, and in communication with the needle, a second reservoir, a reservoir-connecting conduit in communication with the reservoir, a fluid drive in communication with the fluid in the second reservoir and in communication with the reservoir-connecting conduit, and a linear drive attached to the needle or to the needle-receiving member. The fluid drive impel fluids from the second reservoir to the reservoir-connecting conduit and thus drives the therapeutic agent from the reservoir during the linear displacement of the needle towards the housing. Fluid communication from the therapeutic agent reservoir to the needle is maintained by the tubing during operation of the linear drive.

  • Patent number: 9861757
    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: 9457154
    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.
