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).

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: According to a method for preparing and dispensing milk foam a drink made of powdered milk of self-dissolving drink preparation powder, improved milk foam not directly consumed from a preparation vessel (6) is intended to be foamed easily. To this end, at least one hot water stream (2a) is applied to the milk powder or drink preparation powder in the above open or opened preparation vessel (6), in particular a foaming vessel, said hot water stream flowing out of a hot water channel under hot water pressure. The preparation vessel (6) is fixed. The milk foam (22) or drink so prepared in the preparation vessel automatically flows, i.e. merely by way of the effect of the hot water stream and the force of gravity, from the preparation vessel (6) through a laterally and/or downwardly led discharge of the preparation vessel or through an outlet spout to a collection vessel (4), preferably a cup or a glass.

Abstract: A brewing device for a coffee machine, comprising a filter retainer (3), which holds a retention filter (6) for ground coffee beans and which is designed in particular as a filter carrier, a brewing cylinder (4), which can be moved relative to the filter retainer (3) between a loading position for ground coffee beans and a brewing position and which bounds a brewing chamber (13) together with the retention filter (6) of the filter retainer (3) in the brewing position, which brewing chamber has an inlet for pressurized brewing water, wherein a brewing chamber bottom can be moved within the brewing cylinder and the brewing cylinder can be moved into the loading position relative to a scraper in a movement step in order to scrape a cake of used grounds from the brewing chamber, and a cleaning element (7) for removing used coffee grounds adhering to the retention filter (6) after a brewing process during a cleaning motion.

Abstract: A brewing unit (1) of an espresso coffee machine including a brewing chamber (25) and at least one spring-loaded pressure valve (16) which is flow-technically arranged between the brewing chamber (25) and a coffee beverage outlet and which opens when the brewing chamber pressure exceeds a structurally predetermined value. In order to produce by means of the coffee machine one kind of coffee beverage selected from at least two kinds of coffee beverages, an atmospheric coffee beverage bypass channel (21) flow-wisely disposed in parallel relative to the pressure valve (16) between the brewing chamber (25) and the coffee beverage outlet (23) may be locked depending on the kind of coffee beverage selected.
