Bone cement mixing cartridge and method of use

摘要

A container for bone cement includes a first member defining a chamber, which contains a first ingredient. The chamber also includes a second member movably coupled to the first member. The second member includes a mixing device that is movably disposed within the first chamber, and the second member defines a second chamber containing a second ingredient. The container additional includes an opening device that selectively opens the second chamber and allows the second ingredient to enter from the second chamber into the first chamber. The mixing device is movable within the first chamber to promote mixing of the first ingredient and the second ingredient to prepare the bone cement. A corresponding method of preparing bone cement is also disclosed.

1. A method of producing bone cement in a container having a first member that defines a first chamber, an opening device within the first chamber, and a second member movably coupled to the first member, the second member defining a second chamber and including a mixing device movably disposed within the first chamber, the method comprising:
moving the second member of the container relative to the first member to move the mixing device in the first chamber; selectively opening an inlet passage of the second member by selectively piercing a sealing member that seals the second chamber with the opening device within the first chamber to allow a second ingredient in the second chamber to enter the first chamber through the inlet passage; mixing the second ingredient with a first ingredient in the first chamber by moving the mixing device in the first chamber; and after mixing, dispensing the bone cement through an outlet passage that is separate from the inlet passage.
