  • Patent number: 10946136
    Abstract: A delivery device for delivering a medication to a patient includes a catheter with a catheter insertion mechanism, a housing, and a base with a surface for supporting a pump mechanism. A noise dampening member in or on the device inhibits noise and vibrations from the pump mechanism from transferring through the base and housing. The noise dampening member can be an elastomer that is coated on or adhered to the base. The noise dampening member can be molded in or on the base in a suitable location to dampen noise produced by the mechanical component. The noise dampening member can be between the base and the mechanical component or spaced from the mechanical component. The noise dampening member can be molded in a recessed area formed in the base and can have a top face that is recessed, aligned with or project from the top face of the base.

  • Patent number: 10326347
    Abstract: 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.

The automated injector source, delivery scope and applicator can be operably coupled with quick-connect style fittings so as to allow for quick replacement and maintenance of used or damaged components. The automated injector source can include a hands-free input mechanism allowing a medical professional to use both hands in manipulating the delivery scope and needleless applicator at the same time an injection is desired. The delivery scope and needleless applicator can comprise flexible or rigid lengths of tubing based on the accessibility of the treatment site. The needleless delivery system can include an imaging system for precisely position the applicator with respect to the treatment location.

  • Patent number: 9586010
    Abstract: An auto-injector automatically dispenses a predetermined dose of medicament upon activation. The auto-injector includes a needle cover operative to engage an injection site and activate the injector. The needle cover is configured to move from a locked retracted position prior to a medicament dispensing operation to a locked extended position after the medicament dispensing operation. The non-removable needle cover prevents contact with the needle both before and after the medicament dispensing operation.

  • Patent number: 9545483
    Abstract: A drive assembly comprises a housing, a drive member moveable for setting a dose and for delivering the dose. A piston rod adapted to be driven by the drive member in the distal direction during movement of the drive member in the distal direction for dose delivery and a restriction member for restricting proximal movement of the piston rod during proximal movement of the drive member by mechanical interaction of the restriction member with a stop feature. The restriction member and stop feature arranged for the piston rod to be moved proximally a first distance during a first movement of the drive member before the restriction member and stop feature interact mechanically. The first distance the piston rod moves proximally during the first movement of the drive member is different than a subsequent distance the piston rod moves during a subsequent proximal movement of the drive member.

  • Patent number: 9386736
    Abstract: Modular elements employing latches secured by linkages are disclosed. A modular element may include a chassis body in communication with a latch, control body, and control arm of the modular element. The modular element is removable from or secured to an enclosure using the latch. The latch may remain secured to the enclosure in a locked mode by being rotated to engage a control catch of a control arm of a linkage. By connecting the control arm to the control body with a rigid member connected to the control body with first and second rotary joints, the rigid member transforms a control body movement into a rotary motion of the control arm to disengage the control arm from the latch. In this manner, the modular element may be disengaged from the enclosure to facilitate upgrades or maintenance of electronic components supported by the chassis body.
