Nozzle for the supply of biological material, in particular cells, medical device with such a nozzle, use of a nozzle, method for mixing fluids and apparatus

Nozzle for the supply of biological material comprising:

• a mixing chamber (11) which is delimited by a proximal end surface (21) and a distal end surface (22) spaced apart from the proximal end surface (21),
• at least one nozzle opening (23) which is formed in the distal end surface (22),
• at least two supply ducts (30, 40, 50) which discharge into the mixing chamber (11),
• a first supply duct (30) is arranged in the proximal end surface (21) and configured to discharge into the mixing chamber (11) coaxially to the nozzle opening (23), and
• a second supply duct (40) including an inlet opening (42) which discharges into the mixing chamber (11) laterally from and tangentially to an axis passing through the at least one nozzle opening (23) at the distal end surface (22) wherein the inlet opening (42) discharges into the mixing chamber (11) in a plane orthogonal to the axis passing through the at least one nozzle opening (23).
