ABSTRACT:
An electrically powered jet injector impacts a plunger driver against a plunger to generate a high initial pressure pulse, for piercing the skin. The plunger driver then continues to generate a lower delivery pressure until the injection is completed. A microprocessor within the injector controls the speed and direction of the electric motor which moves the plunger driver. The injector provides a subcutaneous injection especially useful for injecting insulin to treat diabetes.
