Magnetic Plungerless Injection System

The Magnetic Plungerless Injection System (MPIS) was invented to enhance the therapeutic value and market availability of parenterally delivered pharmaceuticals and vaccines. The MPIS is a mechanical arrangement of a proprietary single-dosage cartridge and a magnetic actuator, and is a combination of the storage and the injector/extractor (syringe). The design answers many questions raised by the existing hypodermic syringe.
