This evolution of piston-style mixing devices is suitable for mixing quantities of cement up to 120 g. HiVac™7 has a narrow mixing tube which, in combination with a new gun, provides the surgeon with precise control over cement extrusion and the potential to generate increased delivery pressures.
HiVac™7 features a clear tube allowing the clinician to have an unclouded view of the cement during mixing. This offers peace of mind to the user as mix quality can be visually assessed prior to delivery.
To further enhance fatigue life, cement needs to be mixed under optimal vacuum levels. If the vacuum level is too low then the cement will contain high levels of porosity, but if too high, excessive thermal shrinkage can create cracking in the cement mantle. The HiVac™7 range operates at 550 mmHg, which has been shown to give improved mechanical properties.
It remains a closed system during the mixing and delivery process. In addition, charcoal / microbiological filter reduces exposure to methylmethacrylate (MMA) fumes in theatre to levels significantly below those set out in the Health and Safety Executive guidelines.
The mixing rod has a blue section allowing the user to gain accurate alignment, ensuring that when required, the rod is easily and reliably snapped.
HiVac™7 has an elegant ergonomic design, so that the mixer can comfortably be used on a trolley or held in the hand.
