An injection device including a sterile injection needle, the injection device including a container for an injectable product including an outlet for the product at a front end sealed by a membrane, the injection needle, which has a front needle portion facing away from the container for injecting into tissue and a rear needle portion which, in an initial state of the injection device lies opposite and faces the membrane and which is injected through the membrane into the container for an injection, a needle support which holds the injection needle in a central needle portion, and a casing which supports the needle support and the container and movably guides them relative to each other for piercing the membrane, wherein, in the initial state of the injection device, the needle support forms a sterile chamber for the rear needle portion, the chamber sealed by a sealing element on a rear side of the chamber facing the outlet of the container, and wherein the front end of the container for piercing the membrane penetrates through the sealing element into the sterile chamber.
An injection device comprising an injection needle, said injection device comprising:
A needle support for an injection needle, said needle support comprising:
The needle support as set forth in the preceding claim, wherein the outer body comprises at least one fixing element arranged outside the front chamber and outside the rear chamber for operably coupling the needle support to an injection device.
The needle support as set forth in the preceding claim, wherein the outer body is provided with a flange pointing outwardly to form the at least one fixing element.
The needle support as set forth in the preceding claim, wherein said detachable connection is a positive connection.
A needle support for an injection needle, said needle support comprising:
The needle support as set forth in the preceding claim, wherein a sealing element is arranged between the holding body and the protective cap in order to obtain an air-tight connection.
An ampoule for an injection device, containing an injectable product and comprising a product outlet at one end of said ampoule, said outlet being sealed by a membrane which may be pierced by an injection needle, wherein a separating means is formed at the end of the ampoule, to cut through a tensioned film using a relative movement, directed perpendicular to said film, between the ampoule and the film.
The ampoule as set forth in the preceding claim, wherein the separating means forms a separating edge surrounding an longitudinal axis of the product outlet at a radial distance.
