HiVac™7 Bone Cement Mixing and Delivery System

Bone Cementation

HiVac™7 is an evolution of piston - style mixing devices offering significant features and benefits for theatre staff and surgeons.

 

These include:

1. Simple, easy to use design

HiVac™7 has few components and is straightforward to use. This can simplify the product training process allowing clinicians to achieve consistent results

2. Clear mixing tube

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

3. Optimum vacuum of 550mmHg

Research suggests [1] that the optimum vacuum for mixing bone cement is around 550mmHg. If the vacuum applied to cement during mixing is too low then significant levels of porosity may remain. However if the vacuum level is very high the final cement may suffer from excessive shrinkage. This can lead to the formation of micro cracks which, under loading, may open up and lead to fatigue failure.

 

In addition, research [2] suggests that excessive cement shrinkage can lead to the formation of voids at the cement - stem interface.

4. Closed system

Once the cement components have been added HiVac™7 remains a closed system during the mixing and delivery process. This, coupled with an effective charcoal filter, ensures that the user is exposed to fume levels significantly lower than COSHH guidelines [3]

5. Coloured mixing rod snap point

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.

6. Triple mix option

HiVac™7 comes in a full range of sizes for mixing quantities of cement up to 120g (80g Simplex®*).

7. Narrow delivery syringe

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.

 

In addition HiVac™7 has an elegant ergonomic design, so that the mixer can comfortably be used on a trolley or held in the hand.
