DEVICE AND METHOD FOR GENERATING VACUUM FOR VACUUM CEMENTING SYSTEMS A device (1, 20, 40, 60) for generating a vacuum for a vacuum cementing device comprises a channel (50, 70) and a connector for a gas cartridge (44, 64), wherein the connector comprises an opening facility (57, 77) for opening the gas cartridge (44, 64). The gas cartridge (44, 64) can be or is connected through the connector to the channel (50, 70) in a pressure-tight manner such that a gas from the opened gas cartridge (44, 64) flows along the channel (50, 70). The channel (50, 70) connects the connector to the surroundings of the device (1, 20, 40, 60). The channel (50, 70) comprises at least one T-piece (53, 73) having a vacuum connector (12, 32, 52, 72) for the vacuum cementing device, wherein the T-piece (53, 73) is provided as a Venturi nozzle (53, 73) such that the gas from the opened gas cartridge (44, 64) flowing through the channel (50, 70) generates a negative pressure at the vacuum connector (12, 32, 52, 72). A method for generating a negative pressure in a vacuum cementing system comprises the steps of: opening a gas cartridge; the gas from the gas cartridge flowing through a Venturi nozzle by means of which the negative pressure is generated; and applying the negative pressure to the vacuum cementing system. 6 166 16 12 8 2 Figure 1 |
