Doughy Paste-Powder Bone Cement containing Gentamicin

DOUJET consists of paste and powder to be bone cement based on radiopaque polymethyl methacrylate and to contain aminoglycoside antibiotic gentamicin.At blending of both ingredients of paste and powder, the mixture can reach dough time quickly by initial paste viscosity to do operation without additional waiting time.At polymerization after mixing, You can fasten not only implant but also artificial hip joint as well as artificial knee joint for skeletal reinforcement of orthopedics.

The first non-liquid acrylic bone cement

Powder-Liquid system

Powder-Paste system

  • Viscous paste lead instant dough viscosity allowing a surgical working condition
  • Early reached dough condition introduces stable and longer working time
  • Lower thermal sensitivity than liquid system

Easy paste syringe system

Limit MMA evaporation
No need to break ampoule

DOUJET Pre-packed, closed system

Vacuum Powder cartridge, Paste Injector, Vacuum set, Injection nozzle
