Administering device for infusing or injecting a product, comprising a housing () with a first housing shell () and a second housing shell (), a receiver () for the product formed in the housing (), a conveying mechanism () for conveying the product and a seal (), which connects the housing shells () to one another in a pressing contact rendering them watertight, which seal () is or has a sealing lip () which establishes the pressing contact with the first housing shell ().

Self-sealing connection for housing shells of an administering device

Administering device for infusing or injecting a product, comprising a housing () with a receiver () for the product, a compartment () for a power source in order to supply the conveying mechanism () with electrical energy, a first contact spring () which is disposed in the compartment and places a terminal of the power source in an electrically conducting contact by means of a spring force when the power source is disposed in the compartment (), and a second contact spring () for establishing an electrically conducting contact for an opposite terminal of the power source, likewise by means of spring force.

Administering device with a power source contacted by spring force

The invention relates to a needle covering device of an injection device, the injection device including a casing comprising a reservoir, in particular an ampoule, for a product fluid to be administered, and an injection needle for injecting the product fluid from the reservoir, wherein the device surrounds the injection needle in an extended position and exposes the injection needle in a retracted position. The device comprises a passage for the injection needle, a front section via which the device is placed on an injection point, and another section which is nearer to the casing than the front section is, at least in the extended position. The sections can be moved axially relative to the casing and relative to each other, such that the device is variable in its length, the front section being guided in a straight line on the casing.
