  • Publication number: 20160361502
    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.

  • Patent number: 7806866
    Abstract: A device for automatically injecting an active agent, the device involving a syringe filled with an active agent and carrying an injection needle, the syringe displaceable in a receiver by the tension of a spring. A transmission displaceable by at least one spring traverses a first partial path for sticking the injection needle and a second partial path for emptying the active agent from the syringe. The at least one spring acts between the transmission and an intermediate part, and another spring acts between the intermediate part and a support fixedly connected to the receiver. An indicator visible from the outside is connected to the intermediate part, moves only during the second partial path, and traverses a path length that is substantially smaller that the sum of both partial paths.

  • Patent number: 7654987
    Abstract: A device for administering an injectable product including a casing, an injection mechanism including an injection needle pointing in an insertion direction, and a protective cap for the injection needle wherein, in one embodiment, the administering device includes a removing device for removing the protective cap from the injection needle and, in another embodiment, the administering device includes a needle protecting sleeve shiftable generally in alignment with the casing and generally between a front position, advanced relative to the casing, for protecting the injection needle and to a rear position, retracted relative to the casing, for inserting the injection needle into a tissue. In one embodiment, the needle protecting sleeve is prevented from moving completely into the rear position by a lock when the protective cap is protecting the injection needle.

  • Patent number: 7361160
    Abstract: An injection device including a receptacle for an active substance, which is connected to an injection needle and is accommodated inside a sliding sleeve that can be displaced within a housing by a driving force. A sleeve-shaped needle-protecting device is displacable within the housing by a spring such that the needle-protecting device moves forward and extends past the injection needle in an axial direction when the injection needle is withdrawn from the body tissue. A lock prevents the needle-protecting device from being manually pushed backward, the lock effective between the needle-protective device and the sliding sleeve, and being automatically deactivated when the sliding sleeve is at least approximately back in its retracted position.
