Claim of US Patent No. 11,032,898

1. Modular plasma jet treatment system (1), for the treatment of biological materials or medical applications, comprising a plasma source (2) with at least the following components:a high-voltage module (20) comprising a high-voltage electrode (21) and a first connection means for connecting the high-voltage module (20) with a plasma jet applicator (30), wherein
the plasma jet applicator (30) is configured to generate with the high-voltage electrode of the high-voltage module (20) at least one plasma jet (35), wherein the plasma jet applicator (30) has a cavity (31) for a process gas (100), wherein a ceiling portion (32) of the cavity (31) is arranged on the high-voltage module (20) or arranged on the plasma jet applicator (30), the cavity (31) comprising
a) a process gas inlet (33),
b) at least one plasma jet outlet (34),wherein the plasma jet applicator (30) comprises a second connection means, wherein the first and second connection means are configured such that the plasma jet applicator (30) and the high-voltage module (20) are repeatedly connectable and releasable,characterized in that,when the plasma jet applicator (30) is connected to the high-voltage module (20), the cavity (31) is adjacently arranged with the ceiling portion (32) at the high-voltage module (20), and wherein the cavity (31) is separated by a dielectric (23, 47) from the high-voltage electrode (21) of the high-voltage module (20).
