  • Publication number: 20240131317
    Abstract: An integrated disinfection device is described syringe assembly having two integrated disinfection units assembled to a syringe for disinfecting and sterilizing corresponding medical connectors, specifically access ports of corresponding medical connectors. The integrated disinfection unit includes a first cup and a second cup. The first cup having a chamber containing a first absorbent material, a first disinfectant or an antimicrobial agent in the first cup, and a first peelable seal. The second cup having a chamber containing a second absorbent material, a second disinfectant or an antimicrobial agent in the second cup, and a second peelable seal. A threaded connection is disposed on the bottom exterior surface of the first cup having threads that are sized and pitched to engage threads of a luer lock collar on the distal end of the syringe barrel to allow the first cup to be connected to the syringe assembly.

  • Publication number: 20210275707
    Abstract: A disinfection cap is described for connection to a medical connector, the disinfection cap including a housing having a top wall and sidewall forming a cavity, a blockage feature disposed on the top wall of the cavity, the blockage feature for fluidly blocking a hub of a luer connector, disinfectant or antimicrobial agent disposed within an open cell foam structure within the cavity. The open cell foam structure releasing the disinfectant or antimicrobial agent as the open cell foam structure is depressed by the hub of the luer connector.

  • Publication number: 20210146113
    Abstract: A disinfection cap is described for connection to a medical connector, the disinfection cap includes a housing having a top wall and sidewall forming a cavity, disinfectant or antimicrobial agent and a ball disposed within the cavity. An outer surface of the housing includes a thread sufficient to interlock with a mating feature of a threaded connector, or more specifically a male luer connector. The cap may also include a peelable seal to prevent the disinfectant or the antimicrobial agent from exiting the cavity. The cavity of the cap may also include one or more ribs disposed on the inner surface of the cavity to retain the ball in the cavity, forming a flow channel as the ball is depressed further into the cavity. An exterior sidewall surface of the housing may include a plurality of grip members.

  • Patent number: 9664644
    Abstract: A test sensor includes a body, a first conductive trace, a second conductive trace, and a third conductive trace. The body includes a first region that has a fluid-receiving area, a second region separate from the first region, and a first temperature sensing interface disposed at or adjacent to the fluid-receiving area. The fluid-receiving area receives a sample. The first trace is disposed on the body, and at least a portion of the first trace is disposed in the first region. The second and third traces are disposed on the body. The third trace extends from the first to the second regions. The third trace is connected to the first trace at the first temperature sensing interface. The third trace includes a different material than the first trace. A first thermocouple is formed at the first temperature sensing interface. The thermocouple provides temperature data to determine an analyte concentration.

  • Patent number: 8614097
    Abstract: An assembly determines an analyte concentration in a sample of body fluid. The assembly includes a test sensor having a fluid-receiving area for receiving a sample of body fluid, where the fluid-receiving area contains a reagent that produces a measurable reaction with an analyte in the sample. The assembly also includes a meter having a port or opening configured to receive the test sensor; a measurement system configured to determine a measurement of the reaction between the reagent and the analyte; and a temperature-measuring system configured to determine a measurement of the test-sensor temperature when the test sensor is received into the opening. The meter determines a concentration of the analyte in the sample according to the measurement of the reaction and the measurement of the test-sensor temperature.
