摘要： To heat horizontal surfaces on which patients are placed after surgery, an irradiation apparatus with halogen lamps is provided, the radiation of which is directed toward the horizontal surface to heat it. The surface temperature prevailing in the irradiated area of the horizontal resting surface is detected by a pyrometric sensor as long-wave infrared radiation. This temperature value is used as the controlled variable and is compared with a predetermined nominal value, such as 37.degree. C. In the event of a deviation, a control signal corrects the irradiation intensity by adjusting the power supply to the halogen lamps.

摘要： An aspirator pump, especially for medical purposes, has a receptacle with two chambers arranged alongside each other, which are connected with a suction tube, and on each of which an element is arranged which is movable approximately parallel to the other, each partially enclosing a hollow space for generating a vacuum. The two movable elements are connected to each other by means of a lever, whose two end parts are attached at the upper area of the respective movable elements, and whose middle part is movably attached in a bearing positioned between the chambers. In the upper area of each movable element a one way valve is installed which opens when the pressure in the hollow space is higher than the surrounding air pressure. An easy operation and cleaning, as well as a reliable aspiration is obtained with the aspirator pump, owing to the fact that at all times a chamber and a movable element enclose a common, variable hollow space, wherein the movable element bounds the upper area of the hollow space. The two hollow spaces are connected through a common manifold with a connection for the suction tube of a catheter, and an additional one way valve is arranged at the entrance of each hollow space into the manifold, which closes when the pressure in the hollow space is greater than the surrounding pressure.
