Document Type and Number:
Japanese Patent JPH04507366
Kind Code:
A
Abstract:
A mixing device comprises a first cylinder (10) containing a particulate or powdered component (11) and having a closed first end (13, 14) and an opposite second end which is closed by a piston-like venting and filtering assembly (12, 15). The device also comprises a second cylinder (18) containing the liquid component (19) and having a closed end (20, 22) and an opposite open end sealingly receiving the closed end of the first cylinder (10) therein in a piston-like manner. Means (14) are provided for communicating the inner space of the first and second cylinders (10, 18) through the closed end (13, 14) of the first cylinder (10), when the first cylinder is forced into the second cylinder, whereby liquid from the first cylinder is injected into interstices defined between the particulate component contained in the first cylinder for providing a paste-like material. The communicating means is preferably formed by a breakable membrane (14). The venting and filtering assembly (12, 15) may be used as a piston for discharging the paste-like mixture made from the first cylinder (10). The mixing device is preferably used for mixing components so as to form a bone cement.
