Patent ID: 8465197

Claim:
A cartridge for the sterile mixing of a two phase compound consisting of a liquid phase and a solid phase which can be mixed immediately before dispensing, comprising: a first tubular body defining a first collection chamber for a solid phase, said first tubular body extending substantially longitudinal along a longitudinal axis (X); a second tubular body defining a second collection chamber for a liquid phase, said second tubular body being arranged for sliding coaxially to and inside said first tubular body; means for transferring said liquid phase from said second to said first chamber; and means for mixing said liquid phase with said solid phase, wherein said means for mixing comprises a means for agitating acting on the mixture of said phases inside said first chamber with said first tubular body in substantially stationary conditions, so as to favor the dispersion of the solid phase inside the liquid phase thus obtaining a compound with uniform physical and mechanical properties in conditions of absolute sterility, wherein said means for agitating comprises an agitator body which is configured for moving coaxially to and between said first collection chamber and said second collection chamber, said agitator body being substantially hollow for housing and receiving axially said second collection chamber, wherein said agitator body comprises a mobile agitator element housed inside said first collection chamber, wherein said mobile agitator element is coupled to means of movement, comprising a gripping element arranged outside said first and said second chamber, which is suitable to be operated by an operator for moving said mobile agitator element in said first collection chamber, and wherein said agitator body of said means for agitating further comprises a suitable means for linking configured to provide rigid coupling of said gripping element to said mobile agitator element spaced from said longitudinal axis (X).
