Abstract:
1. A device for mixing medical fluids, said device comprising an inlet port for receiving at least a first medical fluid, an injection port for injection of a second medical fluid, an outlet port for exit of a mixed flow of said first and second medical fluids, a first duct extending between said injection port and said inlet port, and a second duct extending between said inlet port and said outlet port, said injection port being sealed by a fluid-proof membrane which can be penetrated by an injection needle when injecting said second medical fluid, at least a first portion made of a first material and a second portion made of a second material, wherein said second material is substantially more resilient than said first material, and said inlet port and said injection port are included in said first portion and said outlet port is included in said second portion wherein said first and second portions are mutually configured to facilitate attachment to each other by means of a combined friction coupling and snap connection providing a first retention force, wherein said fluid-proof membrane of said injection port is designed and arranged to be penetrated by said injection needle, wherein said injection needle is included in a fluid transfer device having connection to a second medical fluid-reservoir at one end and which exhibits an additional fluid-proof membrane at the other end forming a double-membrane coupling with said injection port.
