Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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. 2. Nozzle according to claim 1 , wherein the nozzle is conical in shape. 3. Nozzle according to claim 1 , wherein the nozzle is cylindrical in shape. 4. Nozzle according to claim 1 , wherein the porous gas-permeable material is a porous filter material. 5. Nozzle according to claim 4 , wherein the filter material is a sintered porous thermoplastic polyolefin. 6. Method for degassing and dispensing bone cement, wherein the bone cement is dispensed in a device having a nozzle formed by an elongate hollow body, 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, by applying pressure to the bone cement in the dispensing device, whereby the bone cement is moved into and through the nozzle and air inclusions in the bone cement are pressed outward directly through said section of said wall that is made of said gas permeable material to the ambient.
