Abstract
According to one example, a valve for an apparatus configured to mix bone cement is disclosed. The valve can include a base defining a first portion of a passage. The passage can be configured to allow a component of the bone cement through the valve. The valve can include a projection extending from the base to a base opposing end and forming a second portion of the passage that communicates with the first portion. The projection can have a frustoconically shaped surface that comprises one of an outer surface or an inner surface that forms a part of the second portion of the passage.
Claims22
A valve for an apparatus configured to mix bone cement, the valve comprising:
- a base defining a first portion of a passage, the passage is configured to allow a component of the bone cement through the valve;
- and
- a projection extending from the base to a base opposing end and forming a second portion of the passage that communicates with the first portion, the projection having a frustoconically shaped surface that comprises one of an outer surface or an inner surface that forms a part of the second portion of the passage, wherein the frustoconically shaped surface extends to an outer tip of the projection;
- wherein the projection is formed of elastomeric material having a shape memory configured to collapse the projection to seal the passage at the base opposing end of the projection.
