摘要:
The invention relates to a coupling for tubular elements, with at least one plug and one socket, which plug can be inserted into the socket and can be locked therein, and both the plug and the socket have, extending approximately along their longitudinal axis, a channel for a fluid, said channel being arranged in such a way that the fluid can flow through the coupling in a locked state thereof. The plug can be locked in the socket in at least two locking positions, and the socket and/or the plug has at least one opening such that, in a first locking position, the opening connects the channel for a fluid to the environment, and, in a second locking position, the channel for a fluid is isolated from the environment. The invention relates further to a cannula that comprises such a coupling.

The invention relates to an arrangement (10, 100, 200) for removing carbon dioxide from an extracorporeal flow of blood. The arrangement (10, 100, 200) comprises a filter (12) which has a membrane (16) that separates a blood region (14) from a gas region (18). The extracorporeal flow of blood is passed through the blood region (14) of the filter (12). Likewise, a gas flow of a purge gas is passed through the gas region (18), the purge gas being an inert gas or a mixture of inert gases. Further, the invention relates to a method for removing carbon dioxide from an extracorporeal flow of blood in which likewise an inert gas or a mixture of inert gases is used as a purge gas.
摘要:
A device and method for administering at least one medical gas (NO) to a patient mechanically ventilated by means of a ventilator. The ventilator produces a respiratory gas flow (O2/N2) in a feed line. Gas pulses of the medical gas (NO) are supplied to said respiratory gas flow. The gas pulses are produced and fed into a patient feed line by means of at least two regulating means arranged in parallel. Firstly, the temporal start of at least one future inhalation phase of the patient is determined. Subsequently, the regulating means are controlled by means of a control unit such that a gas pulse is fed into the patient feed line at the determined start of the future inhalation phase. To achieve that the therapy gas is fed into without delay in case of very short inhalation times either nitrogen (N2) or helium (He) is used as carrier gas for the active substance (NO).

The invention relates to an arrangement (10, 100) for removing carbon dioxide from an extracorporeal flow of blood and/or for oxygenating the extracorporeal flow of blood. The arrangement (10, 100) comprises an oxygenator (12), a first gas storage tank (24) in which a first gas is contained and at least a second gas storage tank (24) in which a second gas is contained. Further the device (10, 100) has a gas mixing unit for mixing a purge gas from the first and the second gas and an electronic control unit (30) for controlling the gas mixing unit (50). The control unit (30) comprises an input unit (40) by means of which the content of the first gas in the purge gas is adjustable by an operator, wherein the control unit (30) controls the gas mixing unit (50) such that the purge gas has the adjusted content of the first gas.

A device and method for administering at least one medical gas (NO) to a patient anesthetized and mechanically ventilated by means of an anesthesia machine. The anesthesia machine produces a respiratory gas flow (O2/N2) in a feed line. Gas pulses of the medical gas (NO) are supplied to said respiratory gas flow. The gas pulses are produced and fed into a patient feed line by means of at least two regulating means arranged in parallel. Firstly, the temporal start of at least one future inhalation phase of the patient is determined. Subsequently, the regulating means are controlled by means of a control unit such that a gas pulse is fed into the patient feed line at the determined start of the future inhalation phase.
