Abstract
Official abstract text for this publication.
A needle-free transdermal transport device for transferring a substance across a surface of a biological body includes a reservoir for storing the substance, a nozzle in fluid communication with the reservoir and a controllable electromagnetic actuator in communication with the reservoir. The actuator, referred to as a Lorentz force actuator, includes a stationary magnet assembly and a moving coil assembly. The coil assembly moves a piston having an end portion positioned within the reservoir. The actuator receives an electrical input and generates in response a corresponding force acting on the piston and causing a needle-free transfer of the substance between the reservoir and the biological body. The magnitude, direction and duration of the force are dynamically controlled (e.g., servo-controlled) by the electrical input and can be altered during the course of an actuation cycle. Beneficially, the actuator can be moved in different directions according to the electrical input.
First claim
Opening claim text (preview).
What is claimed is: 1. A needle-free injector device for injecting a substance into a biological body, said device comprising: a reservoir for storing the substance; a nozzle in fluid communication with the reservoir; an electromagnetic actuator in mechanical communication with the reservoir; and a servo-controller for controlling the actuator, the servo-controller during operation causing the actuator to generate a force which produces a needle-free injection of the substan…
