Abstract: The invention relates to a manifold (100) for a closed system (1) for endotracheal ventilation and aspiration of a patient, having a first section (115) and a second section (145), an opening (112) configured for allowing influx of a flushing medium to the first section (115), and a passage (118) configured for allowing advancement of the catheter from the first section (115) and into the second section (145). The invention is characterized by a valve body (132) arranged interiorly of the first section (115) and configured for optionally allowing blocking of the passage (118) in a first position and of the opening (112) in a second position.

Abstract: The present invention relates to a coupling arrangement for a system for endotracheal ventilation of a patient, which system comprises an endotracheal tube and a manifold (100) configured for allowing ventilation of the patient via said endotracheal tube, which manifold (100) has a first coupling means (300) with an axial extent (400) and with engagement means (330); and which endotracheal tube has a second coupling means (400) with an axial extent and with engagement means (420); wherein the coupling arrangement is configured to produce, when the first (300) and the second (400) coupling means are moved together in the axial direction, a locking engagement between die engagement means (33, 420).

Abstract: A rotary atomizer a disc- or wheel-shaped atomizing device is secured to one end of a shaft which is connected with the rotor of a high frequency synchronous electric motor. The motor is operated at a rotational speed substantially higher than the first critical speed of the shaft and atomizing device. The shaft and the rotor of the high frequency motor are designed as one integral unit radially supported only by bearings at either end of a part of the shaft surrounded by the rotor.
