摘要： The present invention pertains to a device for irrigation of and aspiration from body cavities, especially during surgical laparoscopy, comprising a delivery pump and a suction pump and tubing lines, which are connected to these and lead to the body cavity. A device for irrigation of and aspiration from body cavities, which can be operated in a very simple manner and fully meets sterility requirements is provided. The suction pressure and the irrigation pressure can be finely controlled in a simple manner, a control device 1 for alternate irrigation of and aspiration from the body cavity is provided according to the present invention; the control device 1 is connected to a control line 3 and to a control valve 20 arranged in its path and controls the delivery and suction pumps 13 and 14 as a function of this control line, and the setting of the gas ballast in the control line 3 by means of the control valve 20 brings about control of the pressure and/or rotation speed of the delivery and suction pumps 13 and 14 (FIG. 2 l).

摘要： The invention relates to a pressure measurement device (1) for fluids flowing in lines (5, 6), particularly for the flexible tubing lines of pressure-controlled roller pumps (22) for use in arthroscopy and urethroscopy. A membrane (8,8') is provided such that it is impacted on the inside by the fluid. A first pressure sensor (12) is connected to the outside of the membrane for measurement of fluid pressure. The first pressure sensor is connected to an evaluating electronic unit.A second pressure sensor (13) is connected to the evaluating electronic unit and is assigned to the outer side of membrane (8,8'), so that it is possible to effect a pressure monitoring based on the second pressure measurement, e.g., in the form of a measurement of pressure difference.

摘要： The present invention pertains to a device for measuring the urine flow (Uroflow) of a patient, consisting of a measuring head provided with a funnel and an outflow port, and of an electronic evaluating unit.In a prior-art measuring device of this class, the measuring head is mounted oscillatingly in a housing. This has disadvantages in terms of the mechanical design of the measuring device and the accuracy of measurement.To simplify the mechanical design and to increase the accuracy of measurement, the measuring head 1 is provided, according to the present invention, with a slotted pitot tube 4 forming the outflow port 30 and with a pressure sensor 18 measuring the dynamic pressure, and the electronic evaluating unit 9 calculates the flow values from the flow-proportional dynamic pressure measured.
