Publication number: 20240131317Abstract: 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.Type: ApplicationFiled: October 18, 2022Publication date: April 25, 2024Applicant: Becton, Dickinson and CompanyInventors: Alban Yee, Shishir Prasad, Manish Kumar, Narasinha C.

Publication number: 20210146113Abstract: 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.Type: ApplicationFiled: October 26, 2020Publication date: May 20, 2021Applicant: Becton, Dickinson and CompanyInventors: Edward P. Browka, Chang Jiang, Amir Harandi, Tom Moskal, Jiayu Liu, Narasinha C. Parasnis

Patent number: 9664644Abstract: 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.Type: GrantFiled: June 24, 2015Date of Patent: May 30, 2017Assignee: Ascensia Diabetes Care Holdings AGInventors: Steve Hoi-Cheong Sun, Swetha Chinnayelka, John P.
