Continuous feed hypodermic syringe with self contained cartridge dispenser

摘要

A hypodermic syringe and a plurality of single use cartridges able to be successively loaded into said syringe for providing rapid dispensing of a medicant to numerous users without contamination. The cartridges are continuously fed through the syringe to inoculate patients quickly and efficiently. An operator inserts a needle into a patient by pushing a trigger. Prior to insertion, a disinfectant is dispersed from the cartridge to maintain sterility. An operator then pushes in a plunger forcing the medication through the needle into the patient. The needle is pulled back with the plunger out of the patient's skin and back into the cartridge. A new cartridge on a clip is then advanced into the syringe to inoculate the next patient. The syringe and cartridge dispenser further maintains a sterile environment during successive vaccinations reducing the transmission of any disease from patient to patient.
