Abstract:
A turbulator adapted to be mounted to or inserted in an inlet portion of a flow meter for a ventilator is disclosed. The turbulator is adapted to create a turbulent gas flow in the inlet portion downstream of the turbulator upon passage of a gas flow therethrough. A flow meter for a ventilator is provided. The flow meter may comprise such turbulator. The turbulator may be arranged in the inlet portion of the flow meter. A membrane for a ventilator flow meter is provided, as well as a flow meter comprising the membrane. A flow meter comprising a turbulator and a membrane is disclosed.

Claim (Index 20):
A flow meter for use in a ventilator, the flow meter comprising:\n a housing; a tube provided at least partially within the housing, the tube having an inlet portion having a first inner diameter, an outlet portion having a second inner diameter, and an intermediate portion having a third inner diameter which is smaller than both the first inner diameter and the second inner diameter; a first pressure measuring point located in the inlet portion and about the intermediate portion; a second pressure measuring point located in the intermediate portion; and a turbulator provided at the inlet portion of the tube, the turbulator being provided as a hollow cylinder having a cylinder wall and a plate extending across the cylinder wherein the cylinder wall and plate include a plurality of apertures therethrough, wherein the turbulator is adapted to create a turbulent gas flow in the inlet portion downstream of the turbulator upon passage of a gas flow through the inlet portion, wherein the turbulator is arranged in the inlet portion such that the plate is arranged at a distance from an inlet opening of the tube, wherein an annular space is provided between the cylinder wall and the inner wall of the inlet portion; a flexible membrane disposed about the outlet portion of the tube; a flow exhaust channel in fluid communication with the outlet portion of the tube, the exhaust channel at least partly surrounding the tube; a pilot pressure chamber arranged adjacent the outlet portion of the tube and adjacent to the exhaust channel; and a flexible membrane arranged between the pilot pressure chamber and the outlet portion and the exhaust channel, wherein the membrane is arranged such that an air flow resistance of a gas flow from the outlet end and into the exhaust channel will be lowest in a portion of the outlet end most distant from the second pressure measurement point.
