DETAILED DESCRIPTION

(16) In accordance with preferred implementations, a cleaning device can include a cap and a movable septum disposed within the cap. The movable septum can contain a cavity that holds a cleaning agent. When a medical implement is inserted into the cleaning device, the cleaning agent can flow around the septum and be applied to the medical implement. This configuration obviates the need for a foam or wet pad/compressible material that are common in conventional medical implement cleaning devices.

(17) The cleaning agent can be any chemical, substance or material that cleans the site of bacterial or viral microorganisms, or any carrier that contains such chemical, substance or material. Examples of a cleaning agent include, but are not limited to, isopropyl alcohol, chlorhexidine, povidone-iodine, hydrogen peroxide, soap, and hydrochloric acid. In some implementations, the cleaning agent is a fluid or liquid, and can also be implemented as a thixotropic gel, a powder, or other state.

(18) The term medical implement can denote any tool or object that can be used in a medical setting and that connects to a site cleaning device as described herein. Examples of medical implements include, but are not limited to, access ports on tubing sets (extension sets, T-connectors and IV sets), access ports on catheters (both peripheral and central lines), needle free valves, stopcocks, luer connectors, stethoscopes and other components or devices whereby regular cleaning is desired. Medical implements are commercially available in standard sizes. Thus, the end or opening of a site cleaning device can be provided with fittings to accommodate such standard size medical implements.

(19) FIG. 1 illustrates a movable septum 3 that contains a cavity. The cavity can hold a cleaning agent. Movable septum 3 can be made of high density polyethylene (HDPE) or any other plastic that is suitable for long term storage with a cleaning agent. At least one flange 1 can be disposed on the outer edges of movable septum 3. In an example, the flange 1 is a flexible outer perimeter of a circular septum 3. The flange 1 can be curved or angled up or down relative to a top surface and/or bottom surface of the septum 3. When movable septum 3 is moved into a housing, the flange 1 can flex to allow incompressible fluid stored underneath the septum 3 to flow into a region above the septum 3.

(20) Movable septum 3 can have one or more holes 4, apertures, passageways, or fluid-permeable film or other material, that can facilitate the movement of the cleaning agent from one side to another, particularly when the cleaning agent is under pressure, i.e. by the septum 3 being pushed into the housing by a site of a medical implement. In some implementations, movable septum 3 can have no holes at all. The holes 4 can have dimensions that allow the surface tension of the cleaning agent to stay below movable septum 3, particularly in a non-pressurized or low-pressure state. In some implementations, the cleaning agent can be selected such that its viscosity is high enough to keep the cleaning agent in place below movable septum 3. The holes 4 can be sized or configured to release pressure in the cleaning agent at a particular pressure threshold.

(21) Although movable septum 3 is illustrated as having a substantially round and flat shape, any shape can be used. In preferred implementations, the septum 3 has a shape, including a peripheral edge, that corresponds to an internal dimension of the housing. The top surface of movable septum 3 can include one or more raised structures 2, which can be frustoconical, conical, squared or any other shape. Raised structures 2 can maintain a space between a surface of the medical implement and the top surface of the movable septum 3. In some implementations, raised structures 2 can have a depressed (rather than raised) shape, which allow mating of some or a portion of the top surface of the movable septum 3 with the surface of the medical implement that is inserted into the housing, or over which the housing is placed or positioned.

(22) FIG. 2 is a top view of a housing 10 that contains a movable septum 3. The housing includes at least one opening for receiving a site of a medical implement. The housing 10 can include one or more other apertures to allow venting of a cleaning solution or cleaning agent contained within the housing prior to receipt of the site of the medical implement. The one or more other aperture may be separate from the opening, or may be formed after the site of the medical implement is received within the opening of the housing.

(23) When a site of a medical implement is inserted into housing 10, coupling mechanism 11 can fasten the medical implement to the housing. Coupling mechanism 11 can be a threaded ring. The threaded ring can be a separate component that connected with an internal surface of the housing at an opening to the housing, or which is integral to the internal face of housing 10. In some implementations, coupling mechanism 11 can be a flexible membrane, a crushed rib, a compressible material, and the like. Tabs 11A can be disposed along coupling mechanism 11 and can flex when a medical implement is inserted into housing 10. The flexing of tabs 11A can hold the medical implement in place within housing 10.

(24) In some implementations, the coupling mechanism 11 can be configured to provide at least one of the one or more other apertures to allow venting, as described above. For example, the threads of a threaded coupling mechanism 11 can be formed to include a predetermined space between non-circumferential thread portions. Or, the coupling mechanism 11 can include any number of pathways, channels, or other openings to provide the one or more other apertures to allow venting.

(25) FIG. 3 is a cross sectional view of housing 10 and movable septum 3. Flanges 1 can press against an inner wall of housing 10 to create an interference fit. This fit can hold movable septum 3 in place within housing 10. A cleaning agent can be placed or inserted within cavity 17 below movable septum 3. The cleaning agent or solution can be put into the housing first, and then the septum 3 can be placed within the housing 10 to effectively seal or maintain the cleaning agent or solution within the housing 10 until receipt of a site of medical implement. In implementations where coupling mechanism 11 is not integral with housing 10, a mating mechanism 12 can fasten coupling mechanism 11 to the housing. The mating mechanism can be a protrusion that is heat welded to the coupling mechanism. The mating mechanism 12 can reside on or near a mating surface 13 of the housing 10.

(26) FIG. 4 illustrates a medical implement 20 inserted into housing 10. As medical implement 20 is pushed into housing 10, surface 25 on the medical implement can come into contact with frustoconical structures 2. Because frustoconical structures 2 are disposed on movable septum 3, pushing on these raised structures can cause the movable septum to move down into housing 10. As movable septum 3 moves down, the cleaning agent in cavity 17 can be forced around flanges 1 to fill space 28 above the movable septum and around sides or other surfaces of a site of a medical implement. The movable septum 3 can be stopped at a particular level within the housing by one or more protrusions 15 extending up from a distal inner surface of the housing 10 opposite the opening of the housing.

(27) FIGS. 5 and 7 illustrate cross sectional views of a housing 10 and a movable septum 3. In the implementation of FIG. 5, movable septum 3 has a single hole 30. In the implementation of FIG. 7, movable septum 3 has multiple holes 40. Cleaning agent in cavity 17 can flow through holes 30 and 40 into space 28 above movable septum 3 as the septum is pushed down into housing 10. In some alternative implementations, the holes 40 can be included in a mesh or fabric that is breathable, but which can maintain a fluid or solution up to a certain threshold of pressure. In a particular implementation, the septum 3 includes a peripheral ring that extends in a flexible flange, and an inner surface within the peripheral ring is such a mesh or fabric. The fabric can be made of a fabric of rigid material, such as nylon, plastic, carbon fiber, stainless steel, or the like. FIGS. 6 and 8 illustrate top views of FIGS. 5 and 7, respectively.

(28) FIG. 9 is a top view of a housing 50 that includes a male luer 55. A movable septum 58 is disposed around the male luer, and can move relative to the male luer 55. The male leur 55 preferably is unitary with the housing 50, and extending up from an inner surface of the housing opposite of, and toward, the opening of the housing 50. Movable septum 58 can have a doughnut shape, and male luer 55 can be positioned through the opening of the movable septum 55. When a medical implement with a female lumen or channel is inserted into housing 50, male luer 55 can mate with, and friction fit and seal, the female luer lumen or channel. Similar to movable septum 3, movable septum 58 can have a flange disposed around the outer edge of the movable septum and zero, one, or more holes disposed on the surface of the movable septum. In some implementations, movable septum 58 can have a flat surface, a raised surface with frustoconical structures, or a depressed surface. In other implementations, the movable septum 58 can have a flexible flange positioned on an inner periphery or edge of the doughnut shape, or both on inner and outer edges. Alternatively, less than a full perimeter of either inner and/or outer periphery of the movable septum may be flexible to allow passage of a cleaning agent or fluid.

(29) FIG. 10 is a cross sectional view of housing 50 illustrated in FIG. 9. A cleaning agent can be held in cavity 59. The housing 50 can be configured with a coupling mechanism such as a thread, a full threading, one or more flanges, protrusions, flexible tabs, an adhesive, a flexible lip or inwardly directed protrusion, or other type of coupling mechanism, or any combination thereof.

(30) FIG. 11 is a cross sectional view of a movable septum 60 having a bottom edge 64. Movable septum 60 can act as male luer as well as a containment mechanism for a cleaning agent. Flanges 62 can press against the inner wall of housing 10 to keep the cleaning agent in cavity 17. Tapered walls 63 on movable septum 60 can be made from a substantially flexible material that allows the tapered walls to conform to an inserted female luer and seal off the inner lumen of the female luer. As described above, the housing 10 can have one or more protrusions 15 extending up from an inner surface of the housing 10 to provide a stop or limit to the movement of the movable septum 60.

(31) FIG. 12A is a cross sectional view of a flexible housing 70. Housing 70 can include an inwardly projecting feature 71 that can latch onto an inserted medical implement. Using inwardly projecting feature 71 can obviate the need for a separate coupling mechanism (such as a threaded ring) as described above with respect to the implementation of FIG. 2. When a medical implement is inserted into housing 70, raised elements 76 and depressed areas 77 can create a space between the medical implement and movable septum 75. Cleaning agent can reside in cavity 78 and spill into area 79 when the medical implement is inserted into housing 70.

(32) FIG. 12B is a cross sectional view of a medical implement 80 inserted into housing 70. The insertion of medical implement 80 can push movable septum 75 down into housing 70 which, in turn can cause the chemical agent in cavity 78 to spill out into area 79.

(33) The cleaning device described herein can include a removable seal that is disposed on an outer surface of the opening of the housing. The removable seal can be heat-welded or thermally bonded, adhered, glued, or otherwise attached to the housing and removed when the housing is to be provided on the site of the medical implement.

(34) The subject matter described herein can be embodied in systems, apparatus, methods, and/or articles depending on the desired configuration. The implementations set forth in the foregoing description do not represent all implementations consistent with the subject matter described herein. Instead, they are merely some examples consistent with aspects related to the described subject matter.
