    摘要: A gas ratio control device for anesthesia apparatus, includes an anesthetic gas feed line, which has, in a series-connected arrangement, a control valve with an inlet chamber, an anesthetic gas-adjusting valve and a first measuring resistance, and an oxygen feed line, which has a second measuring resistance, wherein the dynamic pressure received from the measuring resistances is sent to a proportional element, which controls the control valve. A flow-proportional addition of the anesthetic gas is possible even at low oxygen flow rates. This is achieved by the outlet chamber and the first pressure chamber being connected to one another in one piece in terms of flow. The anesthetic gas-adjusting valve is arranged in front of the inlet chamber of the control valve in terms of flow. A flow resistance is provided between two chambers limited by diaphragms of the proportional element.

    摘要: A detachable coupling on a rotary drive is provided with first and second coupling surfaces (14, 17) arranged opposite each other. The coupling parts can be assembled without observing a preferential position. The first coupling surface (14) has a plurality of needles (15), which are arranged in a matrix-like pattern and point away from the coupling surface (14). The second coupling surface (17) has a fabric layer (18) designed to receive the needles (15).

    摘要: The invention is directed to a pumping arrangement for supplying a ventilating apparatus with breathing gas. The pumping arrangement includes a piston which runs in a cylinder and the piston is connected via a coupling with a drive unit for generating the pumping strokes. The coupling engages a motion transmitter in the form of a piston rod. Gas connecting ports for the breathing gas to be pumped open into the inner chamber of the cylinder. The pumping arrangement permits the piston-cylinder unit to be simply removed and to be reinstalled with reliable guidance. An automatic latching occurs such that a release and removal of the piston-cylinder unit from the ventilating apparatus and its uncoupling from the drive unit is possible only in a rest condition and not during operation. For exchanging the piston-cylinder unit, the motion actuator in the form of the piston rod moves through a preparatory stroke having an end position in which the coupling as well as the latching of the piston-cylinder unit with respect to the housing can be actuated.
