Abstract: An applicator for applying a microarray, including a housing, a plunger which is arranged in the housing in a linearly movable manner, a holding device for receiving a microarray device, a pressing element for moving the plunger in order to act on a microarray device received by the holding device, and an actuation device which holds the plunger in a first position and releases the plunger for movement. The plunger is released by the actuation device only when the at least two actuators are actuated. Further, an application system with such an applicator and a microarray device and to a method for displacing a plunger are included. The plunger is held in a first position against a pretension, and the plunger is released for movement by the pretension upon carrying out at least two separate actuations, where the at least two actuations must be carried out for the release process.

Abstract: A disposable that is suitable for application in a device for heating a physiological fluid, in particular blood, comprising a conduit for conducting fluid, which conduit comprises conduit sections that are arranged next to each other and bends that connect the conduit section, wherein at least one of the bends comprises a first turbulence-inducing obstruction.

Abstract: The present invention relates to a method for height-adjustment of a support surface for a patient by: a) combining an inflatable support member constructed from a plurality of separate layers with at least a part of an existing bearing structure for persons, b) filling a single layer of the inflatable support member until this layer has been brought under a determined minimal pressure, and c) repeating step b) by filling a subsequent layer of the inflatable support member until the support surface of the patient has reached a desired height. The invention also relates to a method for lowering a support for a patient and an apparatus for height-adjustment of a support surface for a patient.
