<p>A device for breaking an ampoule 2 containing liquid monomer, wherein the device is arranged to receive the ampoule and wherein the device comprises one or more spikes or protrusions 6 for penetrating or fracturing the ampoule along a long side of the ampoule. Preferably, the device has a top and a bottom and a longitudinal axis extending therebetween. The one or more spikes may be mounted on a lever 7 forming a side of the device between the top and the bottom of the device. The lever is moveable toward the longitudinal axis, in use, such that the spikes contact and penetrate the ampoule, which is located in the device, as the lever is closed against the device. Typically, the device comprises a filter (4, Fig. 1). The device is used to deliver the liquid monomer to other components for mixing such that an orthopaedic cement is produced.</p> |
