Abstract: A clamp (1) releases or blocks a fluid connection as desired. A clamping tube (3, 4, 5.1, 5.2, 7.1) of the clamp (1) includes a blocking fluid guide element (7.1) and two connecting fluid guide elements (3, 4). The blocking fluid guide element (7.1) is connected in a fluid-tight manner to the two connecting fluid guide elements (3, 4). A clamping unit of the clamp (1) includes two clamping components (8.1, 10.1, 8.2, 10.2). The blocking fluid guide element (7.1) is located between the two clamping components (8.1, 10.1, 8.2, 10.2). In a releasing state of the clamping unit, the blocking fluid guide element (7.1) establishes a fluid connection between the two connecting fluid guide elements (3, 4). In a blocking state, the two clamping components (8.1, 10.1, 8.2, 10.2) prevent a flow of fluid through the blocking fluid guide element (7.1).

Abstract: An arrangement and a process filter out at least one gas from a gas mixture. A filter unit (4) of the filter arrangement comprises an inlet and an outlet and is adapted to filter the gas out of the gas mixture while the gas mixture flows through the filter unit (4). The filter unit (4) takes up the gas and heats up in the process. A filter temperature sensor (46, 46.2) of the filter arrangement is adapted to measure at least once an indicator of the temperature in a first measuring area (MP, MP.2) inside the filter unit (4). Depending on the measured temperature, a message is generated and output in a form perceptible by a human being. This message includes information about the current state of the filter unit (4).

Abstract: A system (1000) feeds substances to a patient (30) with a ventilation of the patient and with an oxygenation of the patient. The system (1000) has at least one ventilation system (1), a sedation by inhalation system (17) with a dispensing system (7), an oxygenation system (2), a breathing gas dispensing path (3), a purge gas dispensing path (4), a breathing gas connection system (5), a connection element (25) located adjacent to the patient, an oxygenation connection system (6) and a switching unit (8). The switching unit (8) is configured to distribute and to split a quantity of an inhalable substance dispensed into a gas mixture by means of the dispensing system (7) between the connection element (25) located adjacent to the patient and the oxygenation system (2). At least one control unit (9, 10, 11, 12) is configured to control the switching unit (8) and/or the system (1000).

Abstract: A system (1000) for a feeding of substances to a patient (30) with ventilation and oxygenation of the patient. The system (1000) includes a ventilation system (1), an oxygenation system (2), a breathing gas dispensing path (3), a purge gas dispensing path (4), a breathing gas connection system (5), an oxygenation connection system (6), a dispensing system (7), a switching unit (8), and at least one control unit (9). The switching unit (8) is configured for a distribution or splitting of a quantity of a drug or anesthetic active ingredient, which quantity was dispensed into a gas mixture by means of the dispensing system (7), between the ventilation system (1) and the oxygenation system (2). The at least one control unit (9) is configured to control the switching unit (8).
