  • Patent number: 12380996
    Abstract: Software of devices, such as medical devices or other constrained devices configured to implement specific functions, can use content files to determine text strings or other content values to present in association with user interface elements. Devices can receive relevant content files, such as new versions of previously-stored content files or new content files containing text in different languages, from a remote content file repository. The software of the devices can accordingly update content values presented in user interfaces based on newly received content files, without the software being re-coded, the software being restarted, or the devices rebooting.

  • Patent number: 12369794
    Abstract: A system for capturing one or more eye images includes an eye imaging device having a camera configured to capture the eye images. The system determines a workflow for capturing the eye images using the eye imaging device. The workflow is determined based on a risk score for a given patient. The system performs the workflow on the eye imaging device to capture the eye images, conducts a microvascular assessment based on the captured eye images, and adjusts the risk score based on the microvascular assessment.

  • Patent number: 12361821
    Abstract: A device for monitoring a physiological variable determines a starting value for a self-adjusting alarm limit based on an abnormal state of the physiological variable. The device determines a new value for the self-adjusting alarm limit from physiological data values received during a time window. When the new value for the self-adjusting alarm limit moves in a targeted direction, the device resets the self-adjusting alarm limit at the new value.

    Abstract: A male bayonet connector includes a first shaft having a first distal end portion having a first sealing surface configured to form a substantially fluid-tight seal with a female connector, a first proximal end portion opposite the first distal end portion, a first lumen extending substantially along a first longitudinal axis of the first shaft from the first distal end portion to the first proximal end portion, and a first channel formed on an outer surface of the first shaft between the first sealing surface and the first proximal end portion. The first channel at least partially extends circumferentially around the first longitudinal axis. The first channel is also defined by a first distal wall, a first proximal wall opposite the first distal wall, and a first central region extending from the first distal wall to the first proximal wall. The first distal wall includes a first axial length that is at least one of curved or at an acute angle relative to the first longitudinal axis.

  • Patent number: 12318222
    Abstract: A method for guiding electrocardiogram (ECG) electrode placement on a person includes acquiring an image of the person, identifying an externally discernable anatomical landmark on the image, determining target locations for first through nth electrodes as a function of the location of the landmark, and highlighting the target locations on the person. A system for guiding placement of ECG electrodes comprises an imaging device, an illumination source, a processor, and machine readable instructions. The instructions, when executed by the processor, identify at least one marker in an image acquired by the imaging device, determine, as a function of the location of the at least one marker, target locations on the person at which first through nth ECG electrodes should be placed, and cause the illumination source to illuminate the first through nth target locations.

  • Publication number: 20250160662
    Abstract: An imaging system for continuous blood pressure monitoring including determining pulse transit time using ballistocardiography and photoplethysmography is provided. Images received from the imaging system are analyzed to identify heartbeat related micromovements and changes in blood volume at capture points of the body. One or more capture points may have a patch that amplifies heartbeat related movements of the patient's skin beneath the patch. Some patches may include transparent optical filters. Images may be analyzed to identify changes in blood volume at specific capture points on the body using transdermal optical imaging. The micromovements and blood volume may be used to calculate pulse transit time between one or more capture points on the body. Blood pressure may be calculated using the pulse transit time.

  • Patent number: 12300385
    Abstract: An example method includes identifying at least one image of an eye of a patient. The method further includes detecting, by a first computing model, at least one first feature in the at least one image and detecting, by a second computing model, at least one second feature in the at least one image. Further, using a third computing model that is different than the first computing model or the second computing model, the method includes identifying a likelihood that the patient has one or more diseases consistent with the at least one feature and the at least one second feature. A recommendation for care of the patient is generated based on the likelihood.

  • Patent number: 12299872
    Abstract: A system includes a vision screening device having at least one sensor. The system also includes a controller operably connected to the at least one sensor. The controller is configured to cause the at least one sensor to obtain an image of an eye, and to identify a region of interest associated with a macula of the eye. The controller is also configured to identify drusen disposed proximate the macula, and to generate an augmented image of the eye. The augmented image includes a component indicating the drusen.

  • Publication number: 20250131233
    Abstract: Systems and methods for modifying power consumption of a wearable device are provided. The systems and methods include an imaging device, a directional antenna, and a power transmission device in combination with a wearable device. The imaging device, antenna, and power transmission device are positioned and re-positioned so that the wearable device is in the center of the field of view of at least one of the imaging device, antenna, and power transmission device. The systems allow for a decrease in the gain of the wearable device, decreasing power usage. The system may also allow for remote charging of the wearable device.

  • Publication number: 20250114015
    Abstract: A respiration monitor includes a multi-channel respiration sensor including a first electrode that is configured to measure a first capacitance signal transmitted along a first channel and a second electrode that is configured to measure a second capacitance signal transmitted along a second channel. The respiration monitor includes a processor configured to receive the first capacitance signal and the second capacitance signal, compare the first capacitance signal and the second capacitance signal to a respiration threshold, and determine which one of the first capacitance signal or the second capacitance signal is within the respiration threshold. The processor is further configured to, if one of the first capacitance signal or the second capacitance signal is outside of the respiration threshold, extrapolate only the first capacitance signal or the second capacitance signal that is within the respiration threshold to determine a tidal respiration volume.
