Device and method for degassing and dispensing bone cement

摘要

Device and method for degassing and dispensing bone cement that can be used to produce a bone cement that is largely free of air inclusions. The device contains a dispensing tube (1) that comprises at least one section (2,3) that is permeable to gas, but impermeable to bone cement. The bone cement is being moved along the gas-permeable section which causes the gas present in the bone cement to flow through the gas-permeable material.

主权项

1. A nozzle formed by an elongate hollow body for degassing and dispensing bone cement from a cartridge containing said bone cement, said elongate hollow body having a wall, at least one section of which is made of a porous material that is permeable to gas but impermeable to bone cement, integrated in the wall and allowing communication of gas directly from the interior of said hollow body through the section of wall that is made of porous material to the ambient.
