  • Patent number: 11852604
    Abstract: In one embodiment, a system for detecting an analyte in a bodily fluid sample includes an electrochemical biosensor, the electrochemical biosensor configured to receive the bodily fluid sample, test for the analyte, and produce an analyte level for the analyte. The system further includes a mediator, the mediator configured to provide for the testing of the analyte by facilitating electron exchange between the analyte and the biosensor. The system further includes an oxygen tension reducing agent, the oxygen tension reducing agent reducing interference of oxygen with the operation of the mediator.

  • Publication number: 20220211991
    Abstract: A method and device for positioning an expandable support in a blood vessel is disclosed herein. The device may include a handle, a catheter assembly, a core wire, and an expandable support. The expandable support may be used to position the device relative to the arteriotomy, as well as to provide temporary hemostasis. The expandable support may be attached to the catheter assembly at a first end, and to the core wire at a second end to optimize the width of the expandable support based on the function being performed by the expandable support at a given time. The catheter assembly may be able to move relative to the handle and the core wire, thereby moving the first end of the expandable support relative to the handle and the core wire.

  • Patent number: 11143502
    Abstract: In one embodiment, a system for determining the proper positioning of a test strip includes a test strip having a first reading window and a strip holder. The system further includes a meter, the meter receiving and configured to receive the test strip, the meter having a first light source of a first color and a second light source of a second color and a first read window. The meter is configured to illuminate the first light source; detect a first reflectance with the meter through the first read window; and determine if the first reflectance is greater than a no-strip value.

  • Publication number: 20200300836
    Abstract: Systems and methods for point-of-care determination of blood potassium are provided. The approaches are based on the reaction of ADP and PEP in the presence of potassium ion and pyruvate kinase to produce pyruvate and ATP. In one method, the produced pyruvate is reacted with phosphate and mediator, in the presence of pyruvate oxidase, to yield acetylphosphate and reduced mediator, and the reduced mediator is used to determine the blood potassium using conventional electrochemical methods. In an alternative method, the produced pyruvate is reacted with phosphate and oxygen in the presence of pyruvate oxidase to yield acetylphosphate and hydrogen peroxide, and the hydrogen peroxide is measured optically in accordance with known methods.

  • Patent number: 10688486
    Abstract: A pinch wall and dam system for controlling fluid flow movement between a sample receiving pad and a test strip includes a sample receiving pad and a test strip in contact with the sample receiving pad. The fluid seeps more quickly under the first portion of the pinch wall than under the second portion of the pinch wall, such that the test strip becomes saturated prior to excess fluid being absorbed in the portion of the sample receiving pad away from the test strip such that the test strip does not become flooded, the portion of the sample receiving pad positioned away from the test strip being sufficiently sized to absorb the excess fluid. The pinch wall and dam system further includes a dam, sitting on top of the sample receiving pad, the dam preventing the backflow of fluid from an area near the first portion of the pinch wall.
