Abstract: A lighting device for a medical treatment room having a support frame configured to be mounted to a wall or ceiling of the medical treatment room. A first illumination unit on the support frame is configured to provide direct illumination of an operating area and a second illumination unit on the support frame is configured to provide indirect illumination of the operating area. The support frame can be articulated for movement of the first and second illumination units. Movement of the support frame is adapted to activate and deactivate the first and second illumination units. Thus, the lighting device includes a control unit configured to switch the first and second illumination units on and/or off when the support frame is moved relative to the operating area.

Abstract: A filter element has a filter medium with a first end and a second end in an axial direction of the filter medium. A first end disk is connected to the first end and has an outflow opening. A second end disk is connected to the second end and has an engaging section, wherein the engaging section engages a counter engaging section of a filter housing of the filter element such that the filter element is received, secured against rotation, in the filter housing. The second end disk is provided with an aperture.

Abstract: The present invention provides a lighting device for a medical treatment room. One embodiment incorporates a support frame configured to be mounted to a wall or ceiling of the medical treatment room. A first illumination unit on the support frame is configured to provide direct illumination of an operating area and a second illumination unit (on the support frame is configured to provide indirect illumination of the operating area. The support frame can be articulated for movement of the first and second illumination units. Movement of the support frame is adapted to activate and deactivate the first and second illumination units. Thus, the lighting device includes a control unit configured to switch the first and second illumination units on and/or off when the support frame is moved relative to the operating area.

Abstract: A coupling device of a transport cart, through which the transport cart can be coupled to a structure of a supply panel for medical applications, wherein the supply panel can be positioned through a ceiling mount. The coupling device has a first and a second jaw that can be coupled to the structure of the supply panel, wherein, in order to couple the transport cart to the structure, the first jaw, via a first latching device, and the second jaw, via a second latching device, can be locked into a closed position (FIG. 6) from a stopped, uncoupled open position upon mechanical pressure contact with the structure.

Abstract: A coupling device (12) of a transport cart (9), through which the transport cart (9) can he coupled to a structure (15) of a supply panel (13) for medical applications, wherein the supply panel (13) can be positioned through a ceiling mount (14). The coupling device (12) has a first and a second jaw (2, 3) that can be coupled to the structure (15) of the supply panel (13), wherein, in order to couple the transport cart (9) to the structure (15), the first jaw (2), via a first latching device (18.1), and the second jaw (3), via a second latching device (18.2), can be locked into a closed position (20) (FIG. 6) from a stopped, uncoupled open position (19) upon mechanical pressure contact with the structure (15).

Abstract: The support for a load, particularly a lamp, includes a standard spring-loaded arm (3) which is pivotable about a vertical axis and vertically adjustable for holding and positioning the load (4). The spring-loaded arm (3) is connected with other parts (9,8) of the support by engagement of an upwardly directed pin-shaped connector element (5) in a downwardly directed connector pipe or socket section (6), so that the spring-loaded arm (3) is suspended from the other parts. The spring-loaded arm (3) with the upwardly directed pin-shaped connector element (5) has universal applicability in a variety of supports including ceiling or wall supports, which have a cantilever arm (8) from which the connector pipe section (6) extends downwardly, and floor or table supports, which have a stand (14,22) and a support tube (9) extending upward from the stand and having a curved section (10) to which the connector pipe section (6) is attached.

Abstract: In order to minimize the dimensions of the spring (22) and the pump motor in a high-pressure cleaning device comprising a high-pressure pump pumping cleaning liquid out of a suction line (1) into a pressure line (6) leading to a discharge device, a bypass line (18) leading from the pressure line to the suction line, a valve body (19) closing the outlet opening (8) between pressure line and bypass line, an actuating element (20) for the valve body which is movable against the valve body contrary to the action of a spring (22) into a position displacing the valve body into the open position, and an operating cylinder divided by a piston (10) sealingly displaceable therein and coupled to the actuating element into two chambers, (11,12) one of which is arranged between the outlet opening and the bypass line and the other of which communicates with the pressure line via a control line, the control line (13) exits the pressure line (6) in the region of a cross-sectional constriction (15) in this pressure line.
