The assembly constitutes a medical pump, particularly a portable micropump for parenteral administration of medicinal solutions and comprises a first module (2) with reservoir (8) arranged to co-operate with a second motor module (4), pump operation being assured by assembly of the two modules. The first module (2) has a removable sterilizing filter device (3) fitted to the reservoir filler orifice (10), with septum, and incorporating a sterile filter pellet (25) and a needle (28) surrounded by a flexible sleeve (29). A support arm (33) comprises a guiding element (34) to guide said device (3) on perforation of the septum, and a securing unit (40) closing the housing (39) for the second module (4). The first module (2) with said device (3) is in the form of a sterile hermetic package. The assembly offers ease of use and ensures that aseptic conditions are maintained when filling the reservoir (8). |
