    摘要: Disclosed is a respirator which comprises an electronic control device and a pneumatic main line in which the following are connected pneumatically: a respiratory gas source, a valve, a mixing chamber, a gas-dosing unit, and a supply line. The gas-dosing unit is configured to convey external air and/or oxygen and/or anesthetic gas into the mixing chamber, the respiratory gas source is configured to deliver respiratory gas to the supply line, the mixing chamber is configured to make available respiratory gas, the supply line is configured to supply the patient with respiratory gas, and the valve is configured to at least temporarily reduce a stream of respiratory gas to a patient.

    摘要: A fluid flow sensor includes a hollow cylindrical casing containing a large number of solid spheres of identical diameter, packed tightly together. Fluid inflow and fluid outflow blocks are mounted to opposite ends of the casing, forming a fluid-tight seal. The fluid inflow and outflow blocks each enclose a generally conical fluid chamber tapering from where it meets an end of an interior of the casing to a respective inlet passage or outlet passage. Circular grilles divide the casing from each fluid chamber and retain the spheres in place. A pressure differential across the casing is measured via side passages extending laterally from each fluid chamber. For a given fluid, a given casing diameter and a given sphere diameter, this pressure differential can be converted to a fluid flow rate.

    摘要: An breathing or anesthesia apparatus and a process for operating a breathing or anesthesia apparatus are provided in which only a very low energy consumption occurs outside of the operating times. The breathing or anesthesia apparatus (1) is put into an energy-saving mode and a function pretest is performed before putting the apparatus into the energy-saving mode. A function self-test is carried out when the breathing or anesthesia apparatus is put into a standby mode.
