    The present invention relate to a method and corresponding apparatus for just in time mixing of a solid or powdered formulation and its subsequent delivery to a biological body. In some embodiments, a powdered formulation is maintained in a first chamber. A bi-directional electromagnetic actuator is in communication with the chamber. The actuator, when activated, generates a pressure within the first chamber. The pressure results in mixing of the powdered formulation and a diluent in time for delivering into the biological body.

    Patent
    The University of Auckland Library

    It means for conveying solids by the method of the surface of the organism, including (i) the electrical input applied to the controllable electromagnetic actuator; (ii) the actuator corresponding to said generated electrical machine with the electromagnetic input force; and (iii) applying mechanical force to the one end of the receptacle is coupled with the nozzle, the mechanical force generated pressure within the receptacle, with the magnitude of the pressure change and the mechanical force caused by the injection of fluid from the reservoir to drive solid into the organism. The method for delivering a substance to a target body, comprising (i) the needle-free injector near the surface of the target body; (ii) the substance injected into the target body; and (iii) at the same time injected, along the movement of the surface of the needle-free injector thus sweep the surface.

  • Controlled needle-free transport

    Patent
    The University of Auckland Library

    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.
