Embodiment Construction

[0041] figure 1 A schematic illustration of a first exemplary embodiment according to the invention of a device 10 for administering at least one medical gas to a patient 14 artificially resuscitated by means of a breathing device 12 is shown. In this example NO (nitric oxide) was used as the medical gas. The gas is included in the gas cylinder 16 as nitrogen N 2 Mixed gas with nitric oxide NO (NO / N 2 )supply. With pressure regulator 18, NO / N 2 The gas mixture is supplied to the metering device 20 via a connection hose 22 at a connection C of the metering device 20 at a setpoint pressure preset at the pressure regulator 18 . A first conduit 24 realized as a breathing air hose leads from the breathing device 12 to a connecting element 26 realized as a Y-piece. Furthermore, a second line 28 realized as an exhaust air hose and a patient supply line 30 are connected to the connecting element 26 . In the exemplary embodiment, the patient input line 30 is connected to a test l...

Abstract

The invention relates to a device and method for supplying at least one medical gas (NO) to a patient (14) receiving artificial respiration with the aid of a respirator (12). The respirator (12) produces a respiratory-gas flow (O2 / N2) in a feed line (24). Gas pulses of the medical gas (NO) are fed to said respiratory-gas flow. The gas pulses are produced and introduced into a patient feed line (30) with the aid of at least two regulating elements (54 to 60) arranged in parallel. First, the starting time of at least one future inhalation phase of the patient (14) is determined. Subsequently, the regulating elements (54 to 60) are controlled with the aid of a control unit (48) in such a way that a gas pulse is introduced into the patient feed line (30) at the determined start of the future inhalation phase. In order to introduce the therapeutic gas without delay in the event of very short inhalation times, either nitrogen (N2) or helium (He) is used as a carrier gas for the active substance (NO).

Description

technical field [0001] The present invention relates to a method and a device for administering at least one medical gas to a ventilated patient. The breathing apparatus generates a flow of breathing gas in a first conduit delivering breathing gas. A predetermined amount of medical gas to be administered is added to the flow of breathing gas. At least the gas exhaled by the patient and the portion of the breathing gas not inhaled by the patient introduced into the first line from the breathing device and the medical gas introduced into the patient inlet line are conducted via the second line. Background technique [0002] Known from EP 0 937 479 B1, EP 0 937 479 B1, US 5,558,083, EP 0 786 264 B1, EP 1516 639 B1 and EP 0 723 466 B1 for the continuous and pulsatile time-varying delivery of nitric oxide to artificial respiration Patient devices and methods. A control valve is provided here for regulating the nitric oxide quantity, but the control valve always permits the pas...
