DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0050] The following discussion is directed to various embodiments of the invention. The term invention is not intended to refer to any particular embodiment or otherwise limit the scope of the disclosure. Although one or more of these embodiments may be preferred, the embodiments disclosed should not be interpreted, or otherwise used, as limiting the scope of the disclosure, including the claims. In addition, one skilled in the art will understand that the following description has broad application, and the discussion of any embodiment is meant only to be exemplary of that embodiment, and not intended to intimate that the scope of the disclosure, including the claims, is limited to that embodiment.

I. System Embodiment

[0051] Referring to FIG. 2 and FIG. 3, the housing assembly 200 includes a first housing body 204 coupled to a second housing body 208, where the first and second housing body 204, 208, are moveable relative to each between an open position 248 and closed position 312. The housing assembly 200 forms an interior chamber 308 with one or more openings 300a, 300b, when in the closed position 312. Housing assembly 200 also includes one or more cap 236 disposed within the interior chamber 308. Cap 236 may be configured to receive a percutaneous connection on a medical device (e.g., female luer on a three-way stopcock). The interior chamber 308 may have a reflective surface 217. The housing assembly 200 can also include a mateable latch 239 having a lip region 240 on the first housing body 204, and a lip-receiving region 244 on the second housing body 208. Hinge 228 may pivotally connect the first housing body 204 and the second housing body 208 to allow rotation of the first housing body 204 and second housing body 208 between the open position 248 and closed position 312.

[0052] Referring to FIG. 5, the first housing body 204 and second housing body 208 may have a smooth outer surface defined by a first housing body outer surface 400 and second housing body outer surface 404. Label 304 can be adhered to, imprinted into, engraved in, or otherwise visible on an outer surface of the housing assembly 200.

[0053] In a particular embodiment, housing assembly 200 includes a locking mechanism male end 220 disposed on first housing body inner surface 212 and a locking mechanism female end 224 disposed on second housing body inner surface 216. Locking mechanism male end and female end 220, 224, are in locking engagement when housing assembly 200 is in closed position 312 and unlocked when housing assembly 200 is in open position 248. Cap 236 may be made of borosilicate glass or other light transmittable materials and include a light source 232 disposed within the cap 236 that may be used to sanitize a percutaneous connection when connected to the cap 236.

[0054] Referring to FIGS. 9-11, in another aspect a light transmitting region 500 may be disposed on the first housing body 204 and/or the second housing body 208. The light transmitting region 500 may cooperate with an external light source 612 (e.g. ultraviolet light, pulsed xenon, mercury lamp) that may include recharging connections 600, a power source 604, a circuit 608, an activation switch 616, and wires 620, all disposed within a shell casing 624 that can be coupled to the first housing body 204 and/or the second housing body 208.

[0055] Referring to FIGS. 12-13, in another implementation, cap 236 of housing assembly 200 may be coupled to an external percutaneous connection such as an indwelling catheter 700.

[0056] The device can have an electronic control unit, memory, and an interactive monitoring module. In certain aspects the device can transmit and receive information to and/or from an outside third party or an in-house data center. A system can include a wired or wireless secondary device such as a mobile phone, a portable tablet, a laptop computer, a desktop computer, and the like that can be included in the system, the device having a connected modality that can send and/or receive information using a wireless connection (e.g., a Bluetooth connection) or a wired connection (e.g., mini USB), etc. The device can have an electronic control unit, memory, and an interactive monitoring module. The monitoring module can be connected physically or wirelessly and can be configured for taking/measuring or accepting data.

[0057] FIG. 14A-14B shows an aspect where the two halves of the cover or housing assembly (see FIG. 2-FIG. 11 for example) are attached to the three-way stopcock (see FIG. 1 and FIG. 2 for an example) through a link connector 1480. The link provides a connection between the back or posterior aspect of the three way and the cover. The link part hinges in the attachment of the shell to give freedom to move the three way when medication administrations are necessary. FIG. 15A-15B illustrates an alternate configuration where link connector 1480 is integrated or built in to the cover or housing assembly(see FIG. 2-FIG. 11 for example).

[0058] In certain aspects, a non-disposable UV-light generator can be attached to the front or base of the three-way stopcock, it can have a shape of a console disk, or hand-held scanner. The Hand-held device can provide UV treatment without physically touching the three way. In additiona, the hand held deceive can have an infrared (IR) scanner for bar code or optical mark reading, which can provide a certain specific code to activate the UV treatment.

[0059] During the process of medication administration during the night, finding the identification arm band is necessary before medication administration. The identification band can incorporate micro-electronic components similar to those described for the line guard device (photosensor, PCB, battery and LED).

II. Method Embodiment

[0060] Referring to FIG. 1A, FIG. 1B, FIG. 2, and FIG. 3, the operation of the housing assembly 200 will be described with regard to a three-way stopcock 100 as an illustrative example of a percutaneous connection that may be enclosed and sanitized within the housing assembly 200. Side port female luer 104, outlet port female luer 108, three-way knob 112, inlet line 116, and inlet male luer 120, are oriented by the user to fit on top of the first housing body inner surface 212 or second housing body inner surface 216. Side port female luer 104 may then be connected to the cap 236, which may be configured to be a male luer. The first housing body 204 is then rotated relative to the second housing body 208 from the open position 248 to the closed position 312 so that the three-way stopcock 100 is completely enclosed within the interior chamber 308 of the housing assembly 200. Mateable latch 239 is then engaged to secure the three-way stopcock 100 within the interior chamber. Light source 232 is then activated to sterilize the percutaneous connection. In certain aspects the light source is activated upon closing the housing. In a particular aspect the light source is activated manually. In a particular implementation, locking mechanism male end 220 and locking mechanism female end 224 engage each other when housing assembly 200 is in the closed position 312 to prevent three-way knob 112 from turning inside the interior chamber 308.

[0061] The above specification and examples provide a complete description of the structure and use of illustrative embodiments. Although certain embodiments have been described above with a certain degree of particularity, or with reference to one or more individual embodiments, those skilled in the art could make numerous alterations to the disclosed embodiments without departing from the scope of this invention. As such, the various illustrative embodiments of the methods and systems are not intended to be limited to the particular forms disclosed. Rather, they include all modifications and alternatives falling within the scope of the claims, and embodiments other than the one shown may include some or all of the features of the depicted embodiment. For example, elements may be omitted or combined as a unitary structure, and/or connections may be substituted. Further, where appropriate, aspects of any of the examples described above may be combined with aspects of any of the other examples described to form further examples having comparable or different properties and/or functions, and addressing the same or different problems. Similarly, it will be understood that the benefits and advantages described above may relate to one embodiment or may relate to several embodiments.

[0062] The claims are not intended to include, and should not be interpreted to include, means-plus- or step-plus-function limitations, unless such a limitation is explicitly recited in a given claim using the phrase(s) means for or step for, respectively.
