A trolley (1), for a beam-mounted supply unit, for fastening medical devices to a ceiling. The trolley has a chassis (2) which can be meshed with a rail track of the beam-mounted supply unit for moving the trolley (1) along the rail track. A medical device can be fastened to the trolley (1). The trolley has a brake unit (3) with at least one braking element (7), which exerts a braking force on the rail track and/or on the chassis in the activated state of the brake unit (3), so that a movement of the chassis along the rail track is at least made difficult compared to an operating state with the brake unit (3) deactivated. In the activated state of the brake unit (3), the braking force exerted by the braking element (7) on the rail track and/or on the chassis is generated without the aid of electric energy.

Method and system allowing more accurate detection and identification of unwanted arcing include novel processing of signal voltage representing recovered power-line current. In one implementation, arc-faults are detected based on numerical analysis where individual cycles of line voltage and current are observed and data collected during each cycle is processed to estimate likelihood of presence of arc-event within each individual cycle based on pre-defined number of arc-events occurring within pre-defined number of contiguous cycles. In another implementation, fast transient current spikes detection can be done by: computing difference values between consecutive line-current samples collected over a cycle, average of differences, and peak-to-peak value of line-current; comparing each difference value to average of difference; comparing each difference value to peak-to-peak value; and, based on calculation of composite of two comparisons, using thresholds to determine if arcing is present within processed cycle.

The present invention relates to an aerodynamic rail cover for an operating room with laminar airflow. In order to provide measures to improve the provision of a laminar airflow in an operating zone, an aerodynamic rail cover (10) for an operating room with laminar airflow is provided. The rail cover comprises at least one cover component (12), wherein the cover component comprises a base element (14); and an air guiding surface element (16) connected to the base element. The base element is configured to be attached to a portion of a support rail of a ceiling mounted support arrangement of a medical imaging system. The air guiding surface element forms an air guide to be mounted at least temporarily to cover a portion of the support rail and comprises two surface parts (18) that are extending from starting edges (20) on opposite sides of the base element to a common trailing edge (22). Further, the rail cover component is configured to be movably attached to the support rail of the ceiling mounted support arrangement of a medical imaging system.

A mounting device for mounting a stand device under a ceiling in an operating room incorporates a mounting apparatus extending in the longitudinal direction along a mounting axis configured to bear a connection component of the stand device, in particular a spindle; and a ceiling flange configured to mount the mounting apparatus under the ceiling and to support the stand device on the ceiling; wherein the ceiling flange is mountable in different mounting positions along the mounting axis relative to the mounting apparatus on the mounting apparatus in a way that the mounting device is configured to hold the stand device in a height variable manner in different, in particular predefined, height positions. The invention further relates to a mounting system including such a mounting device.

A stand device for arranging in an operating room and for locally moving a medical device can incorporate a braking device having at least one brake to adjust a degree of freedom of movement of the medical device or a support system holding the device, wherein the stand device can further comprise a control device connected to the braking device to evaluate an external force acting on the stand device or a movement caused by the external force and configured to control the braking device and to adjust the degree of freedom of movement. The medical device can be moved without operating a switch/pushbutton. Furthermore, the disclosure relates to control devices and a methods for positioning the medical device.

The invention relates to a suspension system, or pendant unit, intended for attachment to an upper structure at a selectable height for suspending a load wherein the load may comprise a carrier for the one or more medical devices or one or more devices, such as for instance a (target) lighting, monitor, camera or a medical device.

The problem of the known suspension system is that during the entire repositioning the user has to react on the behavior of the system due to a variety of internal and external forces.

It is an object of the invention to provide an alternative suspension system for the known suspension system wherein this problem is addressed.

A medical-gas panel connector system includes a frame assembly. The frame assembly includes a horizontal frame member, a vertical frame member connected to the horizontal frame member, and a ceiling integration assembly. The medical-gas panel connector system also includes a medical-gas outlet removably secured to at least one of the horizontal frame member and the vertical frame member via a bracket. In addition, a manifold is removably secured to the ceiling integration assembly, the manifold being at least partially disposed inside the medical-gas panel connector system, and a flexible gas line connects the manifold to the medical-gas outlet. The medical-gas panel connector can be reconfigured and rearranged within a modular wall system.

A mounting plate for a medical device support system includes opposed major surfaces in a thickness direction. A group of plate mounting orifices is arranged in a hexagon pattern and extends through the opposed major surfaces and defines a perimeter of an area at the major surfaces. A primary orifice extends through the opposed major surfaces, and a group of primary spindle mounting orifices surround the primary orifice and extend through the opposed major surfaces, the primary orifice and the primary spindle mounting orifices located within the defined area. An auxiliary orifice extends through the opposed major surfaces and a group of auxiliary spindle mounting orifices surrounds the auxiliary orifice and extend through the opposed major surfaces, the group of auxiliary spindle mounting orifices defining a perimeter of an auxiliary spindle mounting area at the major surfaces, one of the plate mounting orifices located within the auxiliary spindle mounting area.
