Injection device for injecting soft tissue enhancing fillers, bioactive agents and other biocompatible materials in liquid or gel form

摘要

The present application relates to a hand-held injection device for soft tissue comprising internal components which allows for mixing of materials prior to injection; a cartridge suitable for containing a first injectable material and couplable to a needle; a shell structured to contain the cartridge; a plunger which can be driven through the cartridge; a power source for activating one of the internal components; and a user-programmable controller coupled to the drive mechanism, where a user-defined injection rate can be set; a vial for a second material attached to a pump; the pump being configured to direct the second material through a one way valve into the cartridge for mixing the first material and the second material in the cartridge; a plunger configured to be driven through the cartridge to force the first material mixed with the second material out of the needle.
