Abstract: An autoinjector including a housing, a receptacle for an active substance, which receptacle, together with a connected injection needle, is displaceable within the housing by spring force for inserting the injection needle into a patient, a piston displaceable within the receptacle by spring force for expelling the active substance, a transfer mechanism for transferring the spring force to the receptacle and/or to the piston, a holding mechanism for holding the transfer mechanism, a releasing mechanism for causing the holding mechanism to release the transfer mechanism when the releasing mechanism is moved from a first position into a second position, and a resetting mechanism for moving the releasing mechanism from the first position into the second position without during the move causing the transfer mechanism to be released.

Abstract: A system for administering an injectable product including an injection syringe carrying a needle, a drive unit and a housing for accommodating the injection syringe and the drive unit, wherein the drive unit moves the injection syringe relative to the housing, and wherein, in some embodiments, a retractor mechanism is provided to retract the needle into the housing after the product is administered.

Abstract: A device for administering an injectable product includes a drive unit for driving a drive member in an administering direction, a release mechanism for releasing the drive unit and a locking mechanism which, when locked, prevents the release mechanism from being operated, wherein the locking mechanism is displaceable generally along the longitudinal axis of the device from a locked to an unlocked position and the release mechanism can be moved generally radially with respect to the longitudinal axis for releasing purposes when the locking mechanism is in the unlocked position.

Abstract: An injection device for use with a two-chamber ampoule, wherein the device includes a front casing part with which the two-chamber ampoule can be associated, a rear casing part, a threaded drive accommodated by the rear casing part, a piston rod which, during a blending movement, is moved by the threaded drive toward a dispensing end of the device and slaves at least a closing piston of the two-chamber ampoule in the process, wherein a spring element presses the piston rod toward the dispensing end during a delivery movement.

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.

Abstract: An autoinjector including a housing, a receptacle for an active substance, which receptacle, together with a connected injection needle, is displaceable within the housing by spring force for inserting the injection needle into a patient, a piston displaceable within the receptacle by spring force for expelling the active substance, a transfer mechanism for transferring the spring force to the receptacle and/or to the piston, a holding mechanism for holding the transfer mechanism, a releasing mechanism for causing the holding mechanism to release the transfer mechanism when the releasing mechanism is moved from a first position into a second position, and a resetting mechanism for moving the releasing mechanism from the first position into the second position without during the move causing the transfer mechanism to be released.

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 means of a driving force. A sleeve-shaped needle-protecting device is displacable within the housing by means of a spring such that said 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.

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.

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.

Abstract: An electric toothbrush comprises a manually guided handle and a brush member having a brush head with a plurality of separately rotating bristle holders which are connected in the brush head to gearing driving them. The bristle holders are mounted in an insert which is insertable into the brush head in a releasable manner so as to be easily exchangeable by the user. Each of the bristle holders has a coupling element in the form of a cam which is insertable, by way of a plug-in connection, in a respective groove in a connecting rod which is connected to a drive means in the handle.

Abstract: An electric toothbrush has a reciprocating connecting rod in a brush member. The brush member is constructed as a brush head at its front end and has there two rows of rotatable bristle holders which each engage with a cam in a transversely running groove in the connecting rod. Rectilinear movement of the connecting rod leads to an alternating rotating movement of the bristle holders.
