A gas flow reversing element is disclosed that includes a main piece comprising an inflow region, a nozzle region and a mixing region, and further includes a branching piece. The inflow region connects a pressure connector to a closable outlet opening in the mixing region, the branching piece connecting the nozzle region to a line connector. With the outlet opening opened, gas flow flowing along a first flow path from the pressure connector through the nozzle to the outlet opening, generates a gas flow in the branching piece flowing along a second flow path from the line connector to the outlet opening. The reversing element further includes a bypass, closable by at least one closing element, connecting the pressure connector and the line connector so that a gas flow can flow along a third flow path via the inflow region, and bypass the nozzle via the bypass.

The present invention relates to a plurality of ventilation devices, to ventilation devices having visualization apparatuses, and to methods for operating the ventilation devices. The intent is to minimize the energy input into the at least one airway of a patient as a result of the ventilation.

Devices and methods for ventilating a patient

The present invention relates to an arrangement () comprising a switchable connection () and a gas flow reversing element (), e.g. according to WO 2008/113752 A1, which is suitable for using a gas supply (), in particular oxygen, which is at excess pressure in order to selectively generate a gas stream () from or to a line connection () which can be connected, in particular via a lumen (), to an airway of a patient (); wherein the switchable connection () is arranged at the branching piece () or at the line connection () and switchably connects at least one second line () to the first line (), wherein the switchable connection () has at least two switching positions (), wherein () in the first switching position () the first line () is open and the second line () is closed, such that the gas flow () through the connection () can flow in both directions along the first line (); () in the second switching position (), if the switchable connection () is arranged at the branching piece (), the second line () is fluidically connected, via the connection (), to the line connection () and in particular to the lumen () or, if the switchable connection () is arranged at the line connection (), the second line () is connected to the lumen ().

Arrangement having a gas flow reversing element and a switchable connection

Gas flow reversing element () for the use of a gas supply () under excess pressure, in particular inspiratory gases, for selectively generating a gas flow () from or to a line connector () which can in particular be connected to an airway of a patient, said gas flow reversing element () being designed as a main piece (), the main piece () at least comprising an inflow region (), a nozzle region () and a mixing region (), and further a branching piece (), the inflow region () connecting a pressure connector (), for connection to the gas supply (), to at least one closable outlet opening () arranged in the mixing region (), and the branching piece () connecting the nozzle region () of the main piece () to the line connector (), wherein a nozzle (), particularly an injector nozzle, is configured and arranged in the nozzle region () in such a way that, a gas flow () flowing along a first flow path () through the main piece () from the pressure connector () subsequently through the inflow region (), the flow region (), the nozzle region () and through the nozzle () into the mixing region () to the outlet opening (), with the outlet opening () opened, can generate a gas flow () in the branching piece () flowing along a second flow path () from the line connector () and subsequently through the branching piece (), through the nozzle region () and through the mixing region () to the outlet opening (), wherein the gas flow reversing element () further comprises a bypass () connecting the pressure connector () and the line connector () so that a gas flow () can flow along a third flow path () via the inflow region (), the bypass () and the branching piece (), wherein at least the bypass () and the flow region () are closable by at least one closing element (), so that the gas flow () can bypass the nozzle () in the nozzle region () via the bypass () along the third flow path (). The invention further relates to method for controlling expiration of a patient.

A gas flow reversing element is provided comprising a main piece defining at least one closable outlet opening, a branching piece extending from the main piece, a line connector connected to the distal end of the branching piece, a pressure connector connected to the main piece, the pressure connector being structured to be fluidly connected to a pressurized gas supply; and a nozzle being configured and arranged in the main piece in such a way that a gas flow flowing in the main piece from the pressure connector through the nozzle to the at least one outlet opening, with the at least one outlet opening being disposed in the second open position, a gas flow can also be generated in the branching piece in a direction toward the at least one outlet opening.

The present invention relates to a catheter for ventilating a patient, with a ventilation channel for alternately delivering and removing air and/or oxygen to and from the patient's airways, the catheter having a maximum external diameter of at most 6 mm, mm, and the ventilation channel having an open end, and a connector end for connection to a gas flow reversing element. According to the invention, the catheter is provided with means or elements for measuring the pressure outside the ventilation channel near the open end. The catheter preferably has a pressure measurement channel, with an open measurement end near the open end of the ventilation channel, and a measurement connector piece for connecting a pressure display device. Of particular advantage is a catheter with an expansion body (cuff) that is fluidically connected to a supply channel through which the expansion body can be increased or reduced in size by means of a fluid. The jet ventilation catheter according to the invention permits a novel ventilation principle that can be regarded as a bridge between classical jet ventilation and conventional controlled ventilation and that opens up possibilities for new and improved interventions in the airways.

To provide a dilator which can shorten time of procedure a region of an outer surface of said distal portion is provided with a pattern of depressions having a depth in the interval of 0.1 to 3 mm.

Dilator for performing a percutaneous medical procedure

A nebulizer uses air or preferably oxygen to aerate and transport an anesthetic for providing topical anesthesia to the airway passages of a patient undergoing analysis or treatment by any of several medical instruments used to traverse the airway passages. The nebulizer is preferably applied in connection with fiberoptical diagnostic and therapeutic instruments, such as bronchoscopes, endoscopes and laryngoscopes, and many variations of these instruments. Other liquid, aerosol, and gaseous drugs may also be administered with the nebulizer.
