Abstract: A medical workstation has a control and display unit (1) connected to a patient monitor module (2) via a communications line (5). The medical workstation has an interface accessible to the user for connecting a therapy module (3). The control and display unit (1) has a microprocessor and the therapy module (3) has at least one microprocessor and a nonvolatile memory. The control and display unit (1) has an area (6) that is visible to the user and can be operated by the user with graphic elements for the display and modification of therapy settings. The control and display unit (1) has an operating program, which is designed such that the area (6) on the control and display unit (1) can be operated by the user only in case a compatible therapy module (3) is connected.

Abstract: An anesthesia system with an anesthetic evaporator can be operated even in case of a defect, particularly in case of a power outage. The anesthetic evaporator (10) and a valve arranged upstream of the anesthetic evaporator (10) are provided, whereby the gas flow through the valve (8) is conveyed completely or partially through the anesthetic evaporator (10) or a bypass line (9) past the anesthetic evaporator (10) in case of operation in accordance with the regulations, while the gas flow takes place only through the anesthetic evaporator (10) in case of a defect.

Abstract: An apparatus for medical fluid delivery is to be improved for the sake of simple monitoring of the quantity of medical fluid delivered. For attaining this object, a safety device (15) with a patient model (16) is provided, which from past values and current values of the dosage rate of the medical fluid extrapolates a future medical fluid concentration (17) and switches off the dosage unit (10) for the medical fluid if the extrapolated medical fluid concentration (17) exceeds a predetermined limit value (14).

Abstract: An apparatus for supplying respiratory gas to a patient in which respiratory gas components are metered with great accuracy and sources of error are detected early. The apparatus has metering devices for respiratory gas components which are connected, on the leading side of a mixing chamber volume, to a ring line; a first respiratory gas analyzer on the trailing side of the mixing chamber volume; a second respiratory gas analyzer at a patient connection; a regulating device for the respiratory gas components which controls the delivery of respiratory gas components, as a function of the concentration measured with the second respiratory gas analyzer, in such a way that the difference between a predetermined concentration and a measured concentration at the patient connection is minimized; and means for performing a plausibility comparison between the measured values of the first respiratory gas analyzer and the second respiratory gas analyzer.

Abstract: A respirator for supplying a patient with breathing is provided such that the respiration will not be compromised at the time of a changeover from one form of respiration to another form of respiration. Provisions are made for carrying out a first form of respiration with the corresponding first setting parameters and for taking over the corresponding setting parameters at least partially from the measured values determined during the first form of respiration and the first respiration parameters that remained invariant at the time of the changeover of the forms of respiration at the time of a changeover to a second form of respiration.

Abstract: An improved respirator with a breathing circuit (100) and a corresponding process for operating the respirator are provided. Defined breathing gas volumes can be delivered to the patient and the current operating state can be reliably monitored despite a strong breathing gas volume flow being delivered in the breathing circuit (100). A gas delivery element (1) designed as a rotary compressor is connected on the inlet side to a reversible breathing gas reservoir (7) and on the outlet side to a patient connection piece (9) for inspiration via a first gas volume flow sensor (2) with a first nonreturn valve (11). A second gas volume flow sensor (5) is located in the connection line between the patient connection piece (9) and the patient being inspirated. The patient connection piece (9) is connected for expiration to a second nonreturn valve (10) via a third gas volume flow sensor (3) and to the reversible breathing gas reservoir (7) via a controllable shut-off valve (4).
