Abstract: A medical gear pump is used for suction and irrigation, in particular for endoscopy or the laboratory, and it has two meshing gears as conveying elements, one of which is joined to a drive mechanism. The gears are received in non-journal-mounted fashion in openings, and are each equipped with a helical tooth set. It is proposed to configure the helical tooth set such that, when viewed along a surface line of said gears, at least two tooth tip/root contact points of said meshing gears are present, and a contour of tooth spaces of the one gear is matched to the teeth of the other gear in such a way that when a tooth has completely penetrated into the tooth space, its tooth tip almost completely fills up the tooth space radially inside the pitch circle.

Abstract: A medical pressure transducer is disclosed with a sterilizable pressure dome exhibiting two connections by means of which the pressure dome can be connected to a tube conduit system or the like, the internal pressure of which is to be measured, in such a way that the medium flowing through the tube conduit system passes through the inner space of the pressure dome.The inner space of the pressure dome is constituted by a housing, a sterilizable pressure dome diaphragm transmitting the pressure to an unsterilized pressure sensor, and a relief valve.
