An x-ray diagnostics system has a number of sub-systems, including an x-ray generating system, an image pick-up system, and a patient support system. At least two of these sub-systems have components thereof which are individually suspended by support mechanisms which permit three-dimension movement and adjustment of the component by a motor. The motor is connected to a central computer which controls the motion and positioning of all components for moving the components to selected positions relative to a patient and relative to each other.

X-ray diagnostics system having suspended position adjustable components

In exemplary embodiments, an ultrasonic transducer serves as vibration generator. It is an object of the disclosure to construct such an apparatus which, with the simplest technical construction, is functionally reliable and can be operated in a very adaptable manner and which is simultaneously especially productive with regard to the desired destruction effect. In accordance with the disclosure this object is achieved in that an ultrasonic transducer to be focused on the calculus serves as a direct acoustic irradiator for the calculus, which irradiator has a surface area such that the sound energy per square unit along the transmission path is sufficiently small so as to avoid tissue damage on the one hand, but is sufficiently great at the focus point that is suffices for the destruction of the calculus disposed at the focus, on the other hand.

Apparatus for destroying calculi in body cavities

Apparatus for feeding liquids, particularly medications such as insulin, or the like, to humans or animals comprising a supply reservoir for the liquid, a conveying arrangement connected to the supply reservoir and including a pressure generating device for feeding the liquid by pressure application from the supply reservoir to the body, and a controllable dosing arrangement for producing a desired rate of infusion. The pressure generating device includes an overpressure generator which constantly maintains the liquid present in the supply reservoir under overpressure as distinct from the pressure prevailing at the point of liquid discharge. The dosing arrangement comprises a pilot or switching valve for periodically releasing liquid from the supply reservoir to the body, the switching valve being switchable for the purpose of fine dosing by the discharge of preselectable constant volumes of liquid at periodic intervals predeterminable in accordance with the treatment program.

Apparatus for infusing liquids into human or animal bodies

A warning apparatus for indicating the threat of impending shock, which includes a photoelectric pulse pickup or receiver adapted to be applied onto the skin of a patient. The pulse pickup or receiver is a combined reflective and transmissive receiver, and the pulse pickup has a signal comparison arrangement associated therewith which compares the signal obtained from a reflective and transmissive measurement with predetermined signal threshold or boundary values, and which will generate an output signal for initiation of an alarm when the output signal of the pulse pickup exceeds the boundary value imparted thereto.
