초록 ▼

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.

대표청구항 ▼

An apparatus for manufacturing bone cement by mixing a plurality of constituent components, said apparatus comprising: a mixing cylinder having a bottom and a lid, said bottom being axially movable relative to said lid for expelling bone cement from said cylinder; an agitator axially movably disposed in said cylinder, said agitator including a perforated member; an elongated hollow tube connected to said agitator for guiding bone cement expelled from said cylinder, said tube axially slidably supported by said lid; channel means in said cylinder for drawing gas from said cylinder whereby said constituent components can be drawn into said cylinder; means for connecting said channel means to an evacuation source; and means for introducing said plurality of constituent components into said cylinder.
