  • Patent number: 10034976
    Abstract: A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism having an inlet and an outlet, a first flow path in fluid communication with the inlet and at least partially defined by structure compatible with fluid cartridge modules containing medication fluid, a second flow path in fluid communication with the outlet and terminating at a subcutaneous conduit for a body, and a drive motor that actuates the pump mechanism. An exemplary operating method detects a first installation of a fluid cartridge module in the housing. The detecting occurs after the housing has been affixed to the body and after the subcutaneous conduit has been inserted into the body. In response to the detecting, the operating method initiates an automatic priming operation to prepare the device for delivery of the medication fluid to the body.

  • Publication number: 20180200430
    Abstract: A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism, a transcutaneous conduit assembly having a fluid conduit coupled to the pump mechanism, and an insertion mechanism for inserting the conduit into the body. An exemplary method begins by detecting a first installation of a fluid cartridge module in the housing, wherein the detecting occurs after the housing has been affixed to the body. In response to the detecting, the operating method automatically activates the insertion mechanism to insert the fluid conduit into the body.

  • Patent number: 9879668
    Abstract: A fluid infusion device includes a fluid pump mechanism having a rotor and a stator. The rotor includes an optically detectable feature, a reference surface, and a cam element rising from the reference surface. The stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of angular position of the rotor, wherein the detectable feature rotates and axially translates as a function of angular position of the rotor. A biasing element provides force to urge the rotor cam element toward the stator cam element and toward the reference surface. A drive motor actuates the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. An optical detection circuit interrogates the detectable feature during operation of the fluid pump mechanism to determine an operating condition of the fluid pump mechanism.

  • Publication number: 20170124930
    Abstract: The disclosed subject matter relates to diagnostic procedures and related device architectures that check the operating health of a display element of a host electronic device. In certain embodiments, a method of checking the health of the display element begins by entering a diagnostic health check mode for the host electronic device. The display element is controlled to display a test image while operating in the diagnostic health check mode. The operating current of the display element is measured in association with the display of the test image. The measured operating current is compared against acceptance criteria for the test image, and an alerting action is initiated when the measured operating current does not satisfy the acceptance criteria.

  • Publication number: 20160015887
    Abstract: A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

  • Publication number: 20090284264
    Abstract: An inductance-based cable length-to-fault measurement device and method are described. The cable under test having a per-unit-length inductance is coupled to an inductance-sensitive oscillator, and the frequency of oscillations is evaluated using the following serially coupled modules: a comparator for digitizing the oscillator output, a pre-scaler for oscillation frequency down-conversion, and a microprocessor for counting pulses from the pre-scaler. To remove environmental and manufacturing tolerance dependencies, as well as a battery voltage dependence, the measured frequency of oscillations is compared to a frequency of oscillations of the oscillator having coupled thereto a reference inductor.

    Abstract: A disposable panty shield comprising a thin, highly absorbent pad having a body-contacting surface, an absorbent layer, a liquid barrier, an adhesive layer, and a release layer to protect a positioning adhesive prior to use wherein the panty shield has been densified by fusing all pad layers together in a manner such that the interstitial space between the individual fibers in the densified areas is not sufficient to readily allow fluid to flow through, and the liquid barrier has a contoured surface. The adhesive layer is attached to the liquid barrier such that the adhesive follows the contour of the liquid barrier.
