Objective: To develop a bio-multi-function impact device for the study of maxillofacial impact injury . Methods: This device, driven by high-pressure nitrogen air, was consisted of impact unit, laser speed-measure meter, trigger unit, operation platform and information record unit. Results: A new type of bio-multi-function impact device was manufactured with the function of the impact and project. The impact velocity is from 3 to 40 m/s and can be adjusted. The muzzle velocity of the projectile can reached from 300 to 1 500 m/s and also can be adjusted according to the demand of the experiments. It can record exactly multi-line biomechanic signals. Conclusion: The device is stable and suitable for the study of impact and projectile injury.
