  • Patent number: 10398840
    Abstract: A dispensing device which disperses medicate through a needle across a zone within a body. The device includes a needle which is, during use, becomes encapsulated within a tubular needle-receiving member, a reservoir in fluid communication with the needle, positioned within the housing, and in communication with the needle, a second reservoir, a reservoir-connecting conduit in communication with the reservoir, a fluid drive in communication with the fluid in the second reservoir and in communication with the reservoir-connecting conduit, and a linear drive attached to the needle or to the needle-receiving member. The fluid drive impel fluids from the second reservoir to the reservoir-connecting conduit and thus drives the therapeutic agent from the reservoir during the linear displacement of the needle towards the housing. Fluid communication from the therapeutic agent reservoir to the needle is maintained by the tubing during operation of the linear drive.

  • Patent number: 10278631
    Abstract: Disclosed is a puncturing system for generating a puncture wound for obtaining a sample of a body fluid, comprising a press-on part to be pressed onto a body part in which a puncture wound is to be generated, a trigger, by the actuation of which a user can trigger a puncturing motion of a puncturing element after the press-on part is pressed on, and a testing facility for determining at least one test parameter on which a sample-obtaining probability depends. A securing facility is also provided that, in a locked state, locks the trigger such that no puncturing motion can be triggered, and, in a triggering state, releases the trigger such that a puncturing motion can be triggered by actuation thereof, whereby the securing facility is transitioned from the locked state to the triggering state by the testing facility when the test parameter determined by the testing facility meets defined minimum requirements.

  • Patent number: 10278732
    Abstract: The present embodiments relate generally to systems and methods for measuring an analyte in a host. More particularly, the present embodiments provide sensor applicators and methods of use with activation that implant the sensor, withdraw the insertion needle, engage the transmitter with the housing, and disengage the applicator from the housing. Systems and methods according to present principles allow for such steps to occur without significant loss of spring force, and without deleterious effects such as seal slingshotting.
