Apparatus for Simultaneous Multiple Medicament Administration

Apparatus (1, 50, 110) for simultaneous multiple medicament administration of fluid medicaments with changing flow rates, comprising a housing (2) consisting of a stiff material, a plurality of inlets (3, 53, 111) and one outlet (5, 71), wherein at least two entry chambers (9, 21, 100, 130) communicating with one inlet (5, 71) respectively and being separated from each other impervious to fluids and a collecting point (22, 44, 76) communicating with the outlet (5, 71) are formed within the housing (2),

• characterized in that
• the entry chambers (9, 21, 100, 130) communicate with the collecting point (22, 44, 76) respectively via a flow path in which at least one penetration member (14, 45, 61, 101, 133) is arranged causing a decrease in pressure downstream the penetration member (14, 45, 61, 101, 133) with respect to the pressure upstream the penetration member (14, 45, 61, 101, 133), such that the pressure in the collecting point (22, 44, 76) is lower than the pressure in each inlet (3, 53, 111), wherein at least one of the penetration members (14, 45, 61, 101, 133) arranged in each flow path is a filter member (14, 61) and/or a channel with a portion of decreased cross section area (45, 101, 133).
