Abstract: A medical device (10) for treating a patient, with a device body (12), at which at least one functional unit (14) to be operated manually by a treating person is arranged. The device (10) has a disinfection unit (20), which is provided separately from the functional unit and comprises a housing (22) arranged at the device body (12) with a disinfection chamber (26) for receiving at least one hand of the treating person, a plasma generator (28) arranged in the disinfection chamber for generating an atmospheric plasma (P) disinfecting the hand of the treating person and a control unit (50) for actuating the plasma generator (28).

Abstract: A device (10) for disinfecting wound treatment is described, with a housing (18), with a plasma generator (54) arranged in housing (18) for generating a disinfecting plasma, with a flow module (52) arranged in housing (18) for generating a gas stream, which forms a free jet (32) transporting the disinfecting plasma from housing (18), and with a jet control unit (50) for affecting the free jet (32) in a planned manner by controlling the gas stream generated by flow module (52). Means (10) has, furthermore, a guide apparatus (56) controllable via the jet control unit (50) for guiding the free jet (32).

Abstract: A respiration system with a respirator (2) and with a breathing system (1), which is detachably coupled with the respirator. The coupling between the respirator and the breathing system takes place by at least two connector systems (3). The coupling between the respirator and the breathing system is designed such that the volume flow through the connector systems always takes place in only one direction. A pressure sensor (9; 9?) is preferably combined with at least one of the connector systems (3) such that a unidirectional volume flow, by which the direction of migration of bacteria through the connector system is influenced in the desired manner, becomes established within this connector system (3), as a result of which the connector system and the coupled sensor are kept free from bacteria, viruses and other contaminants.
