Abstract
A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.
Claims19
A mixing device comprising:
- a vial holder;
- a container configured to receive and secure the vial holder therein when engaged with the vial holder, the vial holder and the container forming an enclosure for containing a vial, the container comprising a ledge and a vial-breaking device;
- and
- a mixing vessel comprising a mixing chamber, the vial holder being configured to be advanced toward the vial-breaking device to break the vial and for releasing contents of the vial such that the contents move into the mixing vessel,
- the mixing vessel comprising a port and a syringe that is in communication with the port, the syringe comprising a plunger that is movable within the syringe to draw the contents into the syringe, the mixing vessel being movable relative to the container between a first orientation in which the ledge is spaced apart from the plunger and a second orientation in which the ledge engages the plunger to move the plunger relative to the syringe and drive the contents out of the syringe and the port,
- wherein the vial holder comprises a threaded outer surface and the container comprises a threaded inner surface configured to engage the threaded outer surface to move the vial holder axially relative to the container, and
- wherein the mixing vessel comprises a threaded inner surface that engages a threaded outer surface of the container to move the container axially relative to the mixing vessel.

A mixing device comprising:
- a vial holder;
- a vial coupled to the vial holder;
- a container configured to receive and secure the vial holder therein when engaged with the vial holder, the vial holder and the container forming an enclosure for containing the vial, the container comprising a ledge and a vial-breaking device, the container comprising an elastomeric seal positioned such that the vial-breaking device extends through the seal;
- a mixing vessel comprising a mixing chamber, the vial holder being configured to be advanced toward the vial-breaking device to break the vial and for releasing contents of the vial such that the contents move into the mixing vessel,
- the mixing vessel comprising a port and a syringe that is in communication with the port, the syringe comprising a plunger that is movable within the syringe to draw the contents into the syringe, the mixing vessel being movable relative to the container between a first orientation in which the ledge is spaced apart from the plunger and a second orientation in which the ledge engages the plunger to move the plunger relative to the syringe and drive the contents out of the syringe and the port;
- and
- a one-way valve disposed between the enclosure and the mixing chamber to prevent back flow into the enclosure,
- wherein the vial holder comprises a threaded outer surface and the container comprises a threaded inner surface configured to engage the threaded outer surface to move the vial holder axially relative to the container, and
- wherein the mixing vessel comprises a threaded inner surface that engages a threaded outer surface of the container to move the container axially relative to the mixing vessel.

A mixing device comprising:
- a vial holder;
- a container, the vial holder and the container forming an enclosure, the container comprising a vial-breaking device;
- and
- a mixing vessel comprising a mixing chamber, a port, a syringe that is in communication with the port and a plunger that is movable within the syringe,
- wherein the vial holder comprises a threaded outer surface and the container comprises a threaded inner surface configured to engage the threaded outer surface to move the vial holder axially relative to the container, and
- wherein the mixing vessel comprises a threaded inner surface that engages a threaded outer surface of the container to move the container axially relative to the mixing vessel, and
- wherein the enclosure is configured for disposal of a vial, the vial-breaking device being configured to break the vial to release contents of the vial into the mixing vessel when the vial holder is advanced toward the vial-breaking device, the plunger being movable to draw the contents into the syringe, the contents being driven out of the syringe and the port when the mixing vessel is in the second orientation.
