DETAILED DESCRIPTION

(6) Particular embodiments of the present device will now be described in greater detail with reference to the figures. Like reference numerals apply to similar parts throughout the several views.

(7) FIG. 1 illustrates an example skin marking device 100 which may be sanitized for use in medical applications. Marking device 100 comprises an axial barrel 110. Barrel 110 comprises a grip portion 112 which permits a user to grip marking device 100 during use. Barrel 110 further comprises a tapered portion, or finial, 114 disposed at a first axial end of barrel 110. Finial 114 cooperates with and supports a writing tip 116 which may apply marking fluid to a patient's skin.

(8) Writing tip 116 may be constructed from felt or other porous material to promote the retention and application of marking fluid. In order to prevent the writing tip and/or the marking fluid from hardening and/or drying out, marking device 100 comprises a removable cap 118. Cap 118 may be removably secured to marking device 100 and may cooperate with the barrel 110, such by snapping the cap 118 onto barrel 110 in a conventional fashion, so as to define an air resistant chamber which protects the writing tip 116 from damage and/or drying out. Cap 118 is constructed from a UV-C transparent material. The UV-C transparent material of cap 118 enables the finial 114 and writing tip 116 to be sanitized upon exposure to UV-C radiation.

(9) Referring now to FIG. 2, a second example marking device 200 is illustrated. Marking device 200 is a double-sided marking device in that it has two writing tips, one at each axial end of marking device 200. Depending on the needs of the user, the two writing tips may be the same type of writing tip or two different types of writing tips.

(10) Second example marking device 200 may comprise some of the same elements as marking device 100, including a barrel 210, a grip portion 212, a first finial 214, a first writing tip 216, and a first cap 218. In accordance with the double-sided nature of example marking device 200, it further comprises a second writing end comprising a second finial 220, a second writing tip 222, and a second cap 224.

(11) The double-sided nature of example marking device 200 makes it particularly useful in environments in which medical personnel would conventionally require multiple marking devices for various different tasks. For example, in environments in which medical personnel have a need to mark a patient's body for surgery and a need to update paper records, it would be desirable to have a double-sided marking device having a marker and ballpoint pen writing tip. By combining two writing functions into a single device, example marking device 200 provides efficiency in that fewer marking devices need to be sanitized and fewer marking devices are likely to be misplaced.

(12) Various embodiments of example marking device 200 are envisioned depending on the needs of the user. For example, in the illustrated embodiment first writing tip 216 is a marker, and second writing tip 222 is a ballpoint pen. Of course other combinations are possible, such as an embodiment in which first writing tip 216 is a marker, and second writing tip 222 is a stylus for updating computerized patient records using an electronic tablet or other similar device. Of course, those having ordinary skill in the art will recognize various other useful combinations, all of which are considered to be within the scope of the present application.

(13) In embodiments in which second writing tip 222 is unlikely to dry out, such as for example, where second writing tip 222 is a ballpoint pen tip, second cap 224 may be optional.

(14) Referring now to FIG. 3, a third example marking device 300 is illustrated. Third example marking device 300 may comprise many of the same elements as marking device 100, including a barrel 310, a grip portion 312, a finial 314, a writing tip 316, and a cap 318. In addition, third example marking device 300 comprises a tracking device 320, such as for example, an RFID tracking device.

(15) The inclusion of tracking device 320 with third example marking device 300 enables a medical facility to control its inventory of marking devices. In conjunction with computerized inventory control and tracking applications, medical facilities may collect usage information that can assist in determining the most efficient number and locations for sanitation devices to be distributed within the facility.

(16) Referring now to FIG. 4, a fourth example marking device 400 is illustrated. Fourth example marking device 400 may comprise many of the same elements as marking device 100, including a barrel 410, a grip portion 412, a finial 414, a writing tip 416, and a cap 418. Fourth example marking device 400 further comprises a color-changing material that changes color upon exposure to UV-C light. In the illustrated embodiment, finial 414 comprises such color-changing material. Finial 414 is illustrated as it might appear immediately after device 400 had been irradiated using UV-C light. Although in the illustrated embodiment, only finial 414 comprises the color-changing material, the present application is intended to cover embodiments in which all or any portion of barrel 410 comprises the color-changing material.

(17) The color-changing material may act as an indicator of sanitation. When device 400 has not been sanitized, finial 414 will present a first color. After device 400 has been exposed to UV-C light, finial 414 will change to a different color. By observing the color of finial 414, a user is able to discern whether device 400 has been sanitized and may be safely used in certain medical environments. Because the color-changing material naturally returns to its base color over time, a user can further observe whether a particular sanitization is stale, or is unreliable.

(18) One of ordinary skill in the art will appreciate that any of the marking devices described herein may form part of a more comprehensive sanitization system. For example, the marking devices described herein may cooperate with prior art sanitation devices configured to apply UV-C radiation to a marking device. Examples of such sanitation systems are described in U.S. Pat. Nos. 8,337,770 and 9,345,799, the entirety of which are hereby incorporated by reference.

(19) While the systems, methods, and so on have been illustrated by describing examples, and while the examples have been described in considerable detail, it is not the intention of the applicant to restrict, or in any way, limit the scope of the appended claims to such detail. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the systems, methods, and so on provided herein. Additional advantages and modifications will readily appear to those skilled in the art. Therefore, the invention, in its broader aspects, is not limited to the specific details and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the applicant's general inventive concept. Thus, this application is intended to embrace alterations, modifications, and variations that fall within the scope of the appended claims. The preceding description is not meant to limit the scope of the invention. Rather, the scope of the invention is to be determined by the appended claims and their equivalents.

(20) Finally, to the extent that the term includes or including is employed in the detailed description or the claims, it is intended to be inclusive in a manner similar to the term comprising, as that term is interpreted when employed as a transitional word in a claim. Furthermore, to the extent that the term or is employed in the claims (e.g., A or B) it is intended to mean A or B or both. When the applicants intend to indicate only A or B, but not both, then the term only A or B but not both will be employed. Similarly, when the applicants intend to indicate one and only one of A, B, or C, the applicants will employ the phrase one and only one. Thus, use of the term or herein is the inclusive, and not the exclusive use. See Bryan A. Garner, A Dictionary of Modern Legal Usage 624 (2d. Ed. 1995).
