Abstract

A device is provided for measuring the differential pressure in anesthetic dispensing devices, with which the differential pressure can be measured between two lines (2, 6) for supplying gaseous components to a mixing site (3). The device has at least one differential pressure sensor (11), which is connected with the lines (2, 6) for supplying the gaseous components. Buffer elements (12, 12′) are integrated in the connection between the lines (2, 6) for supplying the gaseous components and the differential pressure sensor (11).
