  • Patent number: 11903710
    Abstract: A fluid control device includes an inlet configured to be placed directly or indirectly in fluid communication with a bodily fluid source and an outlet configured to be placed in fluid communication with a fluid collection device. The fluid control device has a first state in which a negative pressure differential produced from an external source such as the fluid collection device is applied to the fluid control device to draw an initial volume of bodily fluid from the bodily fluid source, through the inlet, and into a sequestration portion of the fluid control device. The fluid control device has a second state in which (1) the sequestration portion sequesters the initial volume, and (2) the negative pressure differential draws a subsequent volume of bodily fluid, being substantially free of contaminants, from the bodily fluid source, through the fluid control device, and into the fluid collection device.

  • Patent number: 11896437
    Abstract: Systems and methods for digital reflex quantization and signature analysis. Movement of a stimulating device invoking a reflex response in an organism is captured as stimuli data. Electromyographic (EMG) of the reflex response is captured as EMG data. Movement resulting from the reflex response of a limb/appendage of the organism is captured as motion data. One or more of the stimuli data, the EMG data, and the motion data are analyzed to determine one or both of a motion signature and an EMG signature defining quantitative evaluation of the reflex response.

    Abstract: Systems, methods and graphical user interfaces for visualizing analyte measurements using animation are presented. For instance, a system for continuously monitoring analyte concentration in a physiological fluid includes a sensor, a transmitter, at least one processor and a display. The display is for outputting a graphical user interface. The display is controlled by the at least one processor to display, using the graphical user interface, historical analyte concentration levels and a trend indication animation. The trend indication animation comprises at least one visual element configured by the at least one processor to have a periodic motion between a first position and a second position on the display in one of a plurality of trend directions. The trend direction of the periodic motion between the first and second positions indicates whether the analyte concentration is increasing or decreasing and the rate of change of the analyte concentration level.

  • Patent number: 11864919
    Abstract: A flexible, passive pressure sensor includes three LC tank circuits. The first LC tank circuit is a pressure sensing LC tank circuit, having a capacitance that varies in response to changes in environmental pressure. The second and third LC tank circuits are reference LC tank circuits, having capacitances that are relatively constant over changes in environmental pressure. A measurement tool measures the resonant frequencies of the three LC tank circuits and then computes a pressure measurement that accounts for changes in resonant frequencies in the LC tank circuits due to environmental effects and deforming.

  • Patent number: 11832924
    Abstract: Methods for dynamically evaluating blood flow are provided. The method may include injecting Indocyanine Green (ICG) into the bloodstream of a patient, such that the ICG perfuses into a tissue of the patient. ICG images of the tissue may be recorded and stored, such that a user may select a range of stored ICG images. Data indicative of the selected range of stored ICG images is automatically normalized and background-filtering, and a dynamic representation of the ICG perfusion may be generated as a function of time based on the normalized and filtered data. As such, a clinical decision may be made based on the dynamic representation of the ICG perfusion.

  • Patent number: 11826154
    Abstract: A method for identifying and treating a neural pathway associated with chronic pain via nerve stimulation and brain wave monitoring of a mammalian brain is described. The method includes positioning a probe to stimulate a target nerve, wherein the target nerve is suspected of being a source of chronic pain; delivering a first nerve stimulation from the probe to the target nerve, wherein the first nerve stimulation is sufficient to elicit a chronic pain response in the brain; and monitoring for evoked potential activity in the brain as a result of the first nerve stimulation. The method can also include delivering second and third nerve stimulations to confirm the correct identification of the neural pathway and to treat the chronic pain, respectively. A system and apparatus for performing a procedure to identify and treat a nerve that is the source of chronic pain are also described.
