Abstract
A device is provided for generating a vacuum for a vacuum cementing device, the device including a channel and a connector for a gas cartridge. The connector has an opener for opening the gas cartridge, and connects the gas cartridge to the channel in a pressure-tight manner, such that gas from the opened gas cartridge flows along the channel to the surroundings of the device. The channel includes at least one T-piece, provided as Venturi nozzle, having a vacuum connector for the vacuum cementing device, such that gas from the opened gas cartridge flowing through the channel generates a negative pressure at the vacuum connector. A method is also provided including steps of opening a gas cartridge, flowing gas from the gas cartridge through a Venturi nozzle, whereby by a negative pressure is generated, and applying the negative pressure to a vacuum cementing system.
