Abstract:
PCT No. PCT/SE90/00018 Sec. 371 Date Oct. 30, 1991 Sec. 102(e) Date Oct. 30, 1991 PCT Filed Jan. 11, 1990 PCT Pub. No. WO90/13264 PCT Pub. Date Nov. 15, 1990.The present invention relates to an arrangement for the manufacture of bone cement by mixing together its constituent components comprising a mixing cylinder (1) in the form of a tube with a bottom (2) and a lid (3) and inside the mixing cylinder an axially movable agitator (4). The agitator consists of a piston-like agitator disc (4a), which is perforated by channels (4a1), through which the components of the bone cement are caused to flow during the mixing procedure and an agitator rod (4b) resembling a piston rod operatively connected to the agitator disc (4a) and supported in the lid (3) in such a way that it is free to slide. The invention is characterized in that the agitator rod (4b) has an axial channel (4b1), which is closed off at the agitator disc (4a) in such a way that it is capable of being opened. The bottom (2) is so arranged, under the effect of an axial force, as to be displaced like a piston axially in the direction of the lid (3), in conjunction with which the bone cement flows out through the channel (4b1) after it has been opened.
