摘要：
The present invention relates to a device for producing bone cement for fixing protheses, whereby the bone cement is produced by mixing various substances with each other in a space (22) of a feed device (20) to provide a setting mass which in set condition is adapted to fix protheses at surrounding bone tissue and whereby the mixture (19) is pressed out from the space (22) by means of the feed device (20) for applying the mixture to the bone tissue. In order to produce non-porous bone cement in one device and to insert this bone cement produced by the same device into the bone tissue, a vacuum source (17) is connectable to said feed device (20) and this vacuum source (17) is adapted to generate such a vacuum, preferably a vacuum of 0,05-0,5 bar absolute pressure, in said feed device (20) during mixing of said various substances therein, that introduction or addition of air into said mixture (19) is minimized.
