  • Patent number: 11998710
    Abstract: The present disclosure provides applicators adapted to or configured to deliver a product therefrom. The applicators can be particularly designed for delivery to certain body parts of the human body, such as to the vaginal area. The applicator can comprise a housing formed of a substantially continuous wall extending along a longitudinal housing axis between a base end and an application end, the substantially continuous wall defining: a base segment extending from the base end toward the applicator end; a delivery segment extending from the applicator end toward the base end; and a compression segment interconnecting the base segment and the delivery segment. The housing can define a substantially hollow interior configured for retaining a product for delivery through the delivery segment.
    Type: Grant

  • Publication number: 20210405045
    Abstract: The present disclosure relates to diagnostic test devices that provide improved communication to a user of one or both of proper functioning of the test device and an analog test result that is provided by the test device. The diagnostic test devices particularly can include one or more sensors effective to indicate application of a sufficient volume of a test fluid and/or can include one or more light sources positioned to illuminate an analog test result for improved visibility and understanding of the analog test result.

  • Publication number: 20210349032
    Abstract: Machine image detection involving a trained classifier is used to detect a result of a test stick diagnostic device configured to detect the presence of an analyte in a test sample. Example implementations include receiving a digital image comprising a depiction of at least a portion of a test stick diagnostic device and applying the digital image to a classifier configured to determine a relative position, relative orientation, and relative scale of the portion of the test stick diagnostic device with respect to the digital image, identify a test result region of the test stick diagnostic device, and detect a test result marking in the test result region of the test stick diagnostic device. An indication of a result of a diagnostic test may be provided based on the detected test result marking.

  • Publication number: 20170136087
    Abstract: A multifunctional polyethylene glycol-based hydrogel that includes a multi-arm polyethylene glycol cross-linking unit covalently bound to at least four multi-arm polyethylene glycol nanocarrier units, wherein each nanocarrier unit includes an agent coupled to the nanocarrier unit and each agent is selected from pH-lowering agents, bioadhesion agents, microbicidal-spermicidal agents, and agents that inhibit free and cell-associated HIV binding, provided that each nanocarrier unit comprises a different agent.
