The invention relates to a device for generating a vacuum for a vacuum cementing device, whereby the device comprises a channel and a connector for a gas cartridge, whereby the connector comprises an opening facility for opening the gas cartridge, and the gas cartridge can be or is connected through the connector to the channel in a pressure-tight manner such that a gas from the opened gas cartridge flows along the channel, whereby the channel connects the connector to the surroundings of the device and the channel comprises at least one T-piece having a vacuum connector for the vacuum cementing device, whereby the T-piece is provided as a Venturi nozzle such that the gas from the opened gas cartridge flowing through the channel generates a negative pressure at the vacuum connector. The invention also relates to a method for generating a negative pressure in a vacuum cementing system, in particular having a device of said type, comprising 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. |
