The present invention provides an apparatus comprising a housing and a flexible reservoir adapted to contain a fluid and having a septum member formed from a needle-penetratable self-sealing material. The flexible reservoir is arranged within the housing in combination with mounting means arranged within or formed by the housing, wherein the mounting means engages the septum member to thereby mount the flexible reservoir relative to the housing. In this way a secure fixation between the reservoir and the housing is provided without having to interfere with the general flexibility of the reservoir, e.g. substantially the entire flexible reservoir apart from the outlet/mounting means may be arranged free to move relative to the housing, this allowing the reservoir to be emptied to a high degree.

1. An apparatus for dispensing medical fluids comprising: a housing,a flexible reservoir containing a medical fluid and comprising first and second flexible foil portions sealed together to form an enclosed cavity for containing the medical fluid, the reservoir having a pouch-like configuration and having a rounded, folded peripheral edge formed from the first and second flexible foil portions, the flexible reservoir comprising a self-sealing septum member formed from a needle-penetratable flexible material, at least a portion of the flexible reservoir being arranged within the housing,the septum member being attached to the flexible foil corresponding to the rounded, folded peripheral edge, anda mount arranged within or formed by the housing, the mount being configured to directly engage the septum member to secure the flexible reservoir relative to the mount. 2. An apparatus as in claim 1, wherein at least a portion of the flexible reservoir apart from the septum member is free to move relative to the mount. 3. An apparatus as in claim 1, further comprising: a fluid conduit having an inlet and an outlet, the inlet being adapted to be arranged in fluid communication with the reservoir through the septum member,wherein the fluid conduit and the reservoir are moveable relative to each other from an initial position in which there is no fluid communication therebetween and a connected position in which the fluid conduit inlet is arranged in fluid communication with the reservoir through the septum member. 4. An apparatus as in claim 3, wherein the inlet of the fluid conduit is in the form of a pointed needle portion. 5. An apparatus as in claim 4, wherein the septum member has been mounted on an outer surface portion of the reservoir by means of welding. 6. An apparatus as in claim 1, further comprising an expelling assembly adapted to expel a fluid contained in the reservoir through a fluid communication made in the septum member. 7. An apparatus as in claim 1, further comprising an expelling assembly having an inlet and an outlet and an internal flow path arranged therebetween, the inlet being adapted to be arranged in fluid communication with the reservoir, the expelling assembly being adapted to expel a fluid contained in the reservoir through the outlet of the expelling assembly. 8. An apparatus as in claim 7, wherein the expelling assembly comprises a fluid connector serving as the inlet for the expelling assembly, wherein the fluid connector is arranged within the interior of the expelling assembly in an initial state, the fluid connector comprising an inlet and an outlet, whereby the fluid connector is arranged to be operated from the initial state and to an operating state in which fluid communication is established between the interior of the reservoir and the interior of the expelling assembly via the fluid connector and with the outlet of the fluid connector being arranged in the flow path of the expelling assembly. 9. An apparatus as in claim 1, wherein the septum member is disc shaped.
