A system for dispensing Botox, anti-venom, local chemotherapy, anesthetics, aesthetic fillers, endogen materials, fat for aesthetic surgery, stem cells, and lethal injection compounds though a sterile syringe. They system uses pressure, generated by a pump unit, to apply force on a syringe containing the materials to be delivered into the patients body. The volume rate and volume per injection are adjustable through user inputs. The injection occurs when the physician activates a momentary switch. The system provides precise control of the injected material thus minimizing the inaccuracies associated with manually injected materials. Additionally, the simplicity of the system eases cleaning and sterilization practices thus minimizing risks of transferring undesirable transmissible agents.
