Abstract: The invention relates to a device for selective ventilation of one or both lungs of a patient, comprising an endotracheal tube to be arranged in the trachea of the patient and having a proximal and a distal end, an endobronchial tube connected thereto and having a proximal and a distal end, the distal end of which extends beyond the distal end of the endotracheal tube, and means for positioning by feel the distal end of the endobronchial tube in at least a longitudinal direction of the trachea. The positioning means are herein adapted to also position the distal end of the endobronchial tube in a peripheral direction of the trachea. The positioning means can be arranged close to the distal end of the endobronchial tube and can extend so far outside the periphery thereof during use that they come to lie on the carina of the patient. The positioning means can also be asymmetrical relative to the periphery of the endotracheal and/or endobronchial tube and can be adapted for co-action with the trachea wall.

Abstract: The invention pertains to an arrangement and a method for the automatic sampling in a storage tank system (1) interconnected to a pipe system (4) for supplying cleaning fluids, particularly in processing systems that are subject to high microbiological quality requirements in the food and beverage industry, particularly in breweries, with a storage tank system (1) that consists of several tanks and a sampling device (5) that is respectively associated with all tanks via permanent pipework. The invention ensures that the entire sampling system including all valves integrated therein can be cleaned and sterilized in a flow-through fashion regardless of the respective content of the tanks. Furthermore, the sampling should take place without a loss of the fluid to be sampled. This is procedurally achieved in that a volume flow Q(P) of the fluid (P) to be sampled is diverted from a selected tank (1.
