Embodiment Construction

[0023] figure 1 The embodiment of the reservoir filling device is shown in a state in which liquid cannot be transferred from the cartridge 3 containing the liquid to the reservoir. An embodiment of the filling device comprises: a housing 1 with a cylindrical outer wall; and a separating wall 8 which divides the housing into two positions, a first position for the reservoir 2 to be filled and a first position for the reservoir 2 to be emptied. The second position of barrel 3. Each position is provided by the walls of the housing 1 , thus providing a tight fit for the device to be placed there, or each position is provided with guide means which guarantee a well-defined final position of the device to be placed. In the simplest form, two or one of said locations comprises only a central part in the form of a separating wall 8 without an outer wall. The position including the guiding device is called the positioning device.

Abstract

The invention relates to a filling device for a reservoir which reservoir is to be filled from a cartridge such as cartridges having rigid walls e.g. made of glass and provided with a membrane which can be penetrated by a needle for protection of the entrance. According to the present invention the filling device comprises - a housing (1 ) which housing (1 ) comprises - a first position means adapted to receive a reservoir (2) for a delivering device, - a second position means adapted to receive a cartridge (3) containing a liquid, - a unit (4) providing a flow path when both the reservoir (2) and the cartridge are received respectively by the first and second positions means, - a venting unit (5, 5a, 5b) providing access of gas to the cartridge (3) during emptying of the cartridge (3). The filling device is characterized in that at least a part of the venting unit (5) is placed off the rotational centre (rc) of the housing and is attached to a part (7) which part (7) can rotate relative to the housing (1 ).

Description

technical field [0001] The invention relates to a filling device for a reservoir to be filled from a cartridge, for example with a rigid wall, for example made of glass, and provided with a needle-penetrable septum protecting the access cylinder. Background technique [0002] Filling devices for reservoirs are known and it is recognized that it may be necessary to drain the container to be emptied to be filled with liquid in order to reduce the cost of filling or refilling the reservoir. [0003] The problem that arises when manufacturing such filling devices is how to arrange the discharge channels so as not to obstruct the filling process or contaminate the filling liquid, which will usually be some kind of drug. [0004] US 4296786 discloses a transfer device for mixing substances in different containers which are each closed by a plug of elastic material with a pierceable membrane. The delivery device consists of a central body portion and a pair of aligned spikes or c...
