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.
Claims20
A device for mixing and containing fumes for a bone cement component comprising:
- a vial holder configured for receiving and holding a vial therein;
- a holder chamber configured to receive and secure the vial holder therein when engaged with the vial holder, the vial holder and the holder chamber forming an enclosure for containing the vial;
- a vial-breaking device disposed in the holder chamber, the vial holder being configured to be advanced toward the vial-breaking device for breaking the vial and for releasing contents of the vial into the holder chamber;
- a filter disposed within the holder chamber;
- and
- an elastomeric seal positioned about the vial-breaking device having a first surface and an opposite second surface, the first surface positioned so as to contact a surface of the vial holder and the second surface positioned to contact a surface of the holder chamber whereby advancement of the vial holder deforms the elastomeric seal from a first diameter that is smaller than the diameter of the holder chamber to a second diameter that is larger than the first diameter and forms a seal against an inside wall of the holder chamber so as to prevent fumes from escaping from the holder chamber.
A system for containing fumes for a bone cement component comprising:
- a vial holder configured for receiving a vial therein and including a holding structure for maintaining the vial in the vial holder, the vial holder having an opening to expose a surface of a vial, the vial including a monomer component for bone cement;
- a holder chamber configured to receive and secure the vial holder, the vial holder being threadedly received in the holder chamber and advanced in an advance direction by employing threads, the vial holder and the holder chamber forming an enclosure for containing the vial;
- a vial-breaking device disposed in the holder chamber, the vial holder being configured to be advanced toward the vial-breaking device for engaging the surface of the vial, breaking the vial and releasing contents of the vial into the holder chamber;
- an elastomeric seal positioned about the vial-breaking device, the elastomeric seal having a first surface and an opposite second surface, the first surface of the elastomeric seal positioned so as to contact a surface of the vial holder and the second surface of the elastomeric seal positioned to contact a surface of the holder chamber so that advancement of the vial holder compresses the elastomeric seal against the surface of the vial holder so as to change the diameter of the elastomeric seal from a first diameter that is smaller than the diameter of the holder chamber to a second diameter that is larger than the first diameter to form a seal against an inside wall of the holder chamber and prevent fumes from escaping from the holder chamber;
- a filter in contact with the holder chamber;
- a port in communication with the holder chamber through the filter;
- a one way valve disposed between the holder chamber and a port to prevent back flow into the holder chamber;
- and
- a dispensing device is connectable to the port for drawing a vacuum at the port to draw the contents of the vial through the filter and into the dispensing device such that fumes are contained in the enclosure and the dispensing device.
