  • Patent number: 11660032
    Abstract: An oxygen-sensing assembly for attachment to a urinary catheter may include a housing having a flow pathway extending between an inlet end and an outlet end thereof, an oxygen sensor in operable communication with the flow pathway of the housing, the oxygen sensor configured to detect oxygen levels of a fluid flowing through the flow pathway and a flowrate sensor configured to detect a flowrate of the fluid flowing through the flow pathway. A risk of acute kidney injury may be determined based on the mass flowrate of oxygen through the flow pathway, determined based on the detected oxygen levels and the flowrate of the fluid through the flow pathway. Related catheter assemblies and methods are also disclosed.
    Type: Grant

  • Patent number: 10973586
    Abstract: Tip confirmation systems and related methods are disclosed. A method of determining one or more properties of a catheter in a patient comprises advancing a catheter in vasculature of a patient, the catheter coupled to at least one radiation source and at least one detector, transmitting source electromagnetic radiation from the at least one radiation source out of the catheter proximate a distal tip thereof, measuring an intensity of backscattered electromagnetic radiation from the at least one radiation source with the at least one detector, and providing a signal indicative of a location of the distal tip within the vasculature based, at least in part, on the measured intensity of the backscattered electromagnetic radiation. Related systems and methods are also disclosed.

  • Publication number: 20170296738
    Abstract: A carrier assembly and related sterile kits are disclosed. The carrier assembly is configured to be used with a sensor assembly for determining a characteristic of a human body. The carrier assembly comprises a frame member comprising a sidewall defining a central opening configured to receive at least a portion of the sensor assembly and laterally extending wing members hingedly attached at a proximal end thereof to the sidewall of the frame member. The laterally extending wing members each comprise a cavity proximate a distal end thereof and configured to receive a magnet. Related kits and systems are also disclosed.
