Patent Images
1. A syringe device making it possible to mix two compounds, at least the first of which is liquid, comprising:
- a syringe provided with a body having an injection end, the syringe adapted to contain said first compound;
means for guiding the injection end of said syringe body in translation between a first withdrawn storage position and a second inserted active position, said guide means including an inner face, a first end emerging opposite the perforable zone of a stopper capable of closing in leaktight manner the opening of a vial intended to contain the other compound and a second end for receiving the injection end of said syringe, said second end comprising means for providing sufficient linkage between said syringe and said guide means while allowing said translation;
an annular seal surrounding said syringe body and secured to said syringe body and disposed between said body and said guide means and close to the second end of the guide means when the syringe is in its first position, said annular seal having an outer face provided with at least one sealing lip for cooperating with the inner face of the guide means; and
communication means for allowing perforation of said stopper and communication of the internal volume of said syringe with the inside of said vial when the injection end of said syringe is brought into its second position.

24. A syringe device making it possible to mix two compounds, at least the first of which is liquid, comprising:
-
a syringe provided with an injection end, the syringe adapted to contain said first compound; means for guiding the injection end of said syringe in translation between a first withdrawn storage position and a second inserted active position, said guide means including a first end emerging opposite the perforable zone of a stopper capable of closing in leaktight manner the opening of a vial intended to contain the other compound and a second end for receiving the injection end of said syringe, said second end comprising means for providing sufficient linkage between said syringe and said guide means while allowing said translation; an annular seal having an inner face sealingly facing the external face of the syringe body and an outer face provided with at least one sealing lip for cooperating with the inner face of said guide means, said annular seal being located close to the second end of the guide means when the syringe is in its first position, said syringe body being provided with a shoulder for moving said annular seal when said syringe body is moved from the first position to the second position; and communication means for allowing perforation of said stopper and communication of the internal volume of said syringe with the inside of said vial when the injection end of said syringe is brought into its second position. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
