摘要： 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.

摘要： An endoscopic instrument includes a first instrument part adapted for introduction into a cavity of a human body and having an introduction channel therein for passage of gas therethrough, and a second instrument part having a connection channel therein adapted to be connected to the first instrument part introduction channel. The second instrument part is adapted for connection to a gas source to provide gas, at a flow rate suitable for insufflation of a human body cavity, from the gas source through the connection channel to the introduction channel for introduction into the human body. A heating device heats the gas in the introduction channel to substantially the temperature of the human body.

摘要： Disclosed is a device for insufflating gas into a corporal cavity of a human or animal body having a connection for a gas source, a measuring unit provided with sensors for the fill gas pressure and the fill gas flow, which are disposed outside said corporal cavity, and a control unit, to which the output signal of the sensors are applied, and which triggers a pressure regulator which reduces or regulates the fill pressure of the gas source to an insufflation pressure (desired gas pressure), which can be set, and a flow regulator which regulates the fill gas flow to a value (desired gas flow), which can be set.
