Embodiment Construction

[0034] 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 constant 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 the feed line (24) with the aid of at least two regulating elements (54 to 60) arranged in parallel. A control unit (48) controls the regulating elements (54 to 60) according to at least one parameter of the respiration of the patient.

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 device generates a flow of breathing gas at least in the region of the duct for conveying the breathing gas. A predetermined amount of medical gas to be administered is added to the flow of breathing gas. The mixture of the breathing gas flow provided by the breathing device and the medical gas added to the breathing gas flow is fed to a connecting piece, for example a so-called Y-piece, from which the patient inlet line leads to the patient requiring artificial respiration and to other lines. At least the gas exhaled by the patient as well as the portion of the breathing gas not inhaled by the patient which is fed into the first line by the breathing device and the medical gas introduced into the first line are discharged via the other line. Background technique [0002] From EP 0 937 479 B1, EP 0 937 479 B1, US 5,...
