Abstract: An anesthesia system for providing a breathing gas enriched with anesthetic has an anesthesia apparatus (2) and at least one anesthetic dispensing device (3), which is detachably coupled with the anesthesia apparatus. A fluid connection (7, 8, 9) is provided between the anesthesia apparatus and the dispensing device, which is designed to send anesthetic from the dispensing device into the anesthesia apparatus. At least one optical interface is provided between the anesthesia apparatus and the dispensing device. At least one display device is provided in the dispensing device. The optical interface has at least one light source (10), which is provided in the anesthesia apparatus, and at least one fiber optic light guide (20), which is provided in the anesthetic dispensing device (3). The light fed by the light source (10) into the fiber optic light guide is sent to the display device to directly or indirectly light the display device.

Abstract: An anesthesia system (1) is provided with an anesthesia apparatus (2), at least one anesthetic dispenser (3) and at least one parameter detection device (7) for detecting at least one parameter of the at least one anesthetic dispenser (3) at the anesthesia apparatus (2). The parameter detection device (7) is provided with an apparatus interface unit (10) with at least one camera (17) at the anesthesia apparatus (2) and with a dispenser interface unit (11) with at least one image pattern (16) at the at least one anesthetic dispenser (3). The at least one image pattern (16) can be detected by the camera (17), and the dispenser interface unit (11) is a passive dispenser interface unit (11).

Abstract: A device for mixing anesthetic vapor with anesthetic gas has a pressure limitation feature achieved in a simple manner. The device has a valve device (11), with which the evaporator is switched on and off. The valve device (11) is equipped with an overpressure release device (22).

Abstract: A pressure-resistant tank for liquids includes a plurality of differently shaped diecast parts (1, 2) made of a first aluminum alloy (cast alloy). The diecast parts (1, 2) are connected by means of a closed weld seam welded with an electron beam with the use of a second aluminum alloy (wrought alloy). The second aluminum alloy has especially a hydrogen content of less than 0.2 mL per 100 g of wrought alloy. The tank for liquids is especially an anesthetic tank and the anesthetic is desflurane.

Abstract: A device is provided for measuring the differential pressure in anesthetic dispensing devices, with which the differential pressure can be measured between two lines (2, 6) for supplying gaseous components to a mixing site (3). The device has at least one differential pressure sensor (11), which is connected with the lines (2, 6) for supplying the gaseous components. Buffer elements (12, 12?) are integrated in the connection between the lines (2, 6) for supplying the gaseous components and the differential pressure sensor (11).

Abstract: An alarm is associated with a device for dispensing volatile anesthetics. The alarm and device is designed such that an alarm is triggered whenever the operating voltage is interrupted and an assembly unit that determines the dispensing of at least one anesthetic is not in a prescribed state of operation.

Abstract: A filling device for an anesthetic evaporator has filling of an anesthetic evaporator is possible. To accomplish the object, an additional vent hole (36), which is opened immediately after the filling in order for excess anesthetic volume to be able to flow out of the filling device into the anesthetic tank (15) of the anesthetic evaporator (2), is provided within the filling device above a fluid channel (14), via which both the gas and liquid exchange takes place during the filling.

Abstract: An anesthetic tank (1) of an anesthetic dispensing unit is used especially for desflurane and has improved reliability of operation by mutually complementing level monitoring devices. The anesthetic tank (1) is equipped with a level tube (3) arranged in or on the outer wall with a connection line (6) into the interior space as well as with an optical level sensor (4). The optical axis (5) of the level sensor (4) is located at the same level as a mark (33) on the level tube (3).
