- antimicrobial devices as described herein may be utilized to disinfect potentially contaminated surfaces of various devices (e.g., medical devices).
- Related assemblies and methods are also disclosed herein.
- Such antimicrobial devices may be configured as a cap having a volume of antimicrobial substance therein.
- the volume of antimicrobial substance may comprise a disinfectant and/or antiseptic (e.g., a disinfectant and/or antiseptic in a fluid state) such as, for example, alcohol (e.g., isopropyl alcohol) at various concentrations (e.g., 50 to 90%), ethanol at various concentrations (e.g., ranging from 50 to 95%), and combinations of these and any other suitable disinfectant and/or antiseptics.
- the cap may be coupled to and used to protect (e.g., by covering a portion of the medical device) and/or disinfect a portion of medical device by receiving the portion of the medical device (e.g., at least temporarily) within the cap.
- such antimicrobial devices reduce the likelihood of microorganisms entering the bloodstream of a subject via a medical device or assembly configured to deliver fluid to a subject and/or remove a fluid from a subject.
- the antimicrobial device may be utilized with one or more portions of fluid flow or fluid delivery systems such as, for example, an intravenous (IV) device that delivers substances (e.g., fluid) to and from one or more veins of a subject.
- IV devices may include a peripheral IV line having a cannula in communication with the vasculature of a subject.
- the IV device may include one or more connections, valves, and access ports for delivering fluids to and from the subject that may become contaminated while the IV device is connected to the subject (e.g., in fluid communication with one or more portions of subject's internal systems).
- the peripheral IV line may include one or more of needle injection sites (e.g., y-sites), needleless injection sites (e.g., a luer-activated valve (LAV)), and other fluid transfer devices.
- LAV luer-activated valve
- antimicrobial devices as disclosed herein may be utilized with any such connectors, valves, and access ports in such fluid flow or fluid delivery systems.
- the antimicrobial devices disclosed herein may be particularly useful in at least temporarily (e.g., transiently, for a selected period a time) connecting to (e.g., coupling and retaining) to one or more portions of a medical device, such as, the various portions of fluid systems discussed above in order to disinfect and/or protect portions of the medical device that are exposed to potential contamination during use (e.g., during use with a subject).
- the antimicrobial device may disinfect and protect a portion of the medical device from further contamination as the antimicrobial device remains secured to the medical device in disinfecting contact with the portion of the medical device.
- Such antimicrobial devices are typically configured to connect and secure to both a portion of a medical device lacking a threaded connection and/or a portion of a medical including threaded connection (e.g., threads of a Luer connection).
- the antimicrobial device may be configured to connect and secure to a portion of medical device with or without a threaded connection.
- the antimicrobial device includes a flexible member (e.g., a membrane) configured to engage with a portion of a non-threaded (e.g., having a smooth surface, a flat surface, an uneven non-threaded surface, or combinations thereof) access port of a medical device (e.g., a needle injection site of an rV device).
- the flexible membrane of the antimicrobial device may also engage with a portion of a threaded portion (e.g., threads of Luer connection) of an access port of a medical device (e.g., a needleless injection site of an IV device).
- a threaded portion e.g., threads of Luer connection
- the flexible member alone may engage and secure the threaded portion (e.g., the threads) of the medical device to retain the portion of the medical device within a housing of the antimicrobial device without the need for a set of complementary threads on the housing.
- the flexible member or membrane of the antimicrobial device is flexible in the sense that the membrane is easily deformable by a medical practitioner as the practitioner installs and removes the antimicrobial device from the portion of the medical by hand.
- the stiffhess of the flexible member may be selected based on the configuration of the flexible member of the antimicrobial device. For example, a flexible member such as that shown in FIG. 10, which has a relatively small contact surface with the medical device, may have a relatively greater stiffhess in order to retain the medical device.
- a flexible member such as that shown in FIG. 12, which has a relatively larger contact surface with the medical device, may have a relatively lower stiffness in order to retain the medical device.
- Such antimicrobial devices including a flexible member may be relatively more robust than a threaded cap having a disinfectant therein as such threaded caps are generally limited to connecting only with one particular type of a complementary threaded portion of a medical device. Further, the threading protruding from an inner surface within the threaded cap limits the size (e.g., diameter) of the portions of the medical device that may be received within the threaded cap.

- the portion of the medical device 10 may be inserted through the opening 412 in the membrane 408 and at least partially into the throat portion 416 of the membrane 408.
- the portion of the medical device 10 may be forced through the opening to elastically deform at least a portion of the membrane 408.
- the portion of the medical device 10 having a substantially smooth surface may be forced through the opening to elastically deform one or more of the lateral portion 41 1 , the throat portion 416, and the threads 418 of the membrane 408.
- the throat portion 416 (and, in some embodiments, the threads 418) of the membrane 408 may provide a greater contact surface area between the portion of the medical device 10 and the membrane 408 to retain the portion of the medical device 10 in the housing 102.
