[0040] According to some aspects, the swab stick handle may be constructed using one or more of the following materials: polypropylene, polyethylene terephthalate (PET),high-density polyethylene (HDPE), low-density polyethylene (LDPE), polycarbonate (PC), Polytetrafluoroethylene (PTFE), Polyetheretherketone (PEEK), Polyamide-imide any heat resistant plastic, or any combination thereof.

[0041] According to some aspects, the swab stick applicator, a portion of the overall swab stick, may be constructed using one or more of the following materials: polyurethane, polyether, any heat resistant foam, or any combination thereof.

[0042] According to some aspects, the swab stick applicator may be constructed of the following dimensions: 0.3” to 2” long, 0.2” to 1.5” wide and 0.05” to 1.5” deep. More specifically, 0.5” to 1.5” long, 0.3” to 0.8” wide and 0.1” to 0.8” deep.

[0043] According to some aspects, the swab stick handle may be constructed of the following dimensions: 2” to 7” long, 0.1” to 1” wide and 0.05” to 1” deep. More specifically, 3” to 5” long, 0.1” to 0.5” wide and 0.08” to 0.5” deep.

[0044] FIGs. 1-5 (as described below) together make up a preferred swab stick. The swab stick is rigid enough to support clinical applications and is compatible with contact solutions. The swab stick 100 may also be terminally sterilized prior to use through the following methods: moist heat sterilization, dry heat sterilization, ionizing radiation sterilization (such as gamma sterilization), e-beam sterilization, and / or water cascade or waterfall sterilization.

[0045] For example, moist heat sterilization may be performed in a pressurized chamber called an autoclave. The swab stick 100 may be placed inside the autoclave, which is then closed and turned on. The chamber is filled with pressurized steam at a temperature of 121 degrees Celsius / 250 degrees Fahrenheit. Further, for example, dry heat sterilization is accomplished by the conduction of heat. Heat is absorbed by the outside surface of the device and is transferred through the entire device till the target temperature is attained. Dry heat kills microorganism by oxidizing molecules. Further, for example, sterilization by ionizing radiation, primarily by cobalt 60 gamma rays or electron accelerators, is a low-temperature sterilization method. Further, for example, e-beam sterilization (electron beam sterilization) is a form of radiation sterilization that utilizes beta particles to inactivate microbes. Electron beam systems scan medical devices with focused electrons (beta particles) to sterilize them. E-beam delivers higher dosage rates with less penetration compared to gamma radiation. Further, for example, water cascade or waterfall sterilizers may be used for the sterilization of heat sensitive products and materials. The sterilizationprinciples are equal to a steam sterilizer / autoclave but at lower temperatures and therefore longer sterilization cycles.

[0046] According to one aspect of the disclosure, the swab stick 100 may be packaged before or after sterilization, depending upon the sterilization process described above, into a package containing a plurality of swab sticks, for example, 3 in a package. Although 3 swab sticks are referenced, any number may be packaged together. Further, additionally or alternatively, the swab stick or swab sticks may be provided in sterile packaging as known in the art.

[0047] Referring to the Figures, FIG. 1 illustrates a perspective view of a swab stick 100. As illustrated in FIG. 1, the swab stick 100 may comprise a swab stick handle 102 and a swab stick applicator 104. The swab stick handle 102 may comprise an upper portion 106 and a lower portion 108. Further, the swab stick handle 102 may comprise a top portion 110 and a side portion 112. At one end of the lower portion 108 includes an end 114. The end 114, as shown in dashed lines is illustrated as a rounded shape. In one aspect of the disclosure the end 114 may be any shape required for an end, for example, rounded, square, open etc. The other end of the lower portion 108 connects to the upper portion 106. At one end of the elongated upper portion includes a second end (not shown) which is attached to swab stick applicator 104. The other end of the upper portion 106 connects to the lower portion 108. End 114 and the second end (not shown) may be flat or rounded to provide flexibility in the manufacturing process, thereby including processes such as molding or extrusion of the swab stick handle 102.

[0048] The break lines (broken lines) illustrated between the upper portion 106 and the lower portion 108 are merely shown to illustrate an indefinite length of the swab stick handle 102. Upper portion 106 and lower portion 108 may be provided as discrete portions that are connected via any known method, or they may be unitary. The swab stick length promotes application of the contact solution. For example, the length of the swab stick handle 102 provides the rigidity required for the suitable application to skin of a patient.

[0049] As described above, the swab stick handle 102 may be elongated and may be shaped in an ergonomic shape. In one aspect of the disclosure, the ergonomic shape may be a square, oval, any polygonal flat shape or any irregular shape. In another aspect of the disclosure, the swab stick handle 102 may include grooves (not illustrated). Preferably, the swab stick handle may have a plurality of flat surfaces forming a cross-sectionalregular or irregular polygonal shape, such as a triangle, square, pentagon, hexagon, heptagon, octagon, nonagon or decagon.

[0050] In some embodiments, the swab stick handle 102 including the ergonomic shape includes at least a side portion 112 and at least a top portion 110. In one aspect of the disclosure, the swab stick handle may have a plurality of side portions 112 and a plurality of top portions 110 based upon the ergonomic shape. The transition between the side portion 112 and the top portion 110 may be smooth or may be squared (for example, including a sharp edge). For example, the transitions of the swab stick handle 102 with the ergonomic shape allows for a non-cylindrical shape thereby preventing rolling in the hand of a practitioner. The lack of movement in the hand of the practitioner aids in consistency for application of the contact solution.

[0051] Further, the swab stick 100 includes swab stick applicator 104. The swab stick applicator 104 includes a tip 116 and a base 120. In one aspect of the disclosure, the tip 116 includes a rounded shape, as illustrated. In another aspect of the disclosure, the tip 116 may include any variety of shapes available for an applicator, for example, triangular or squared. In another aspect of the disclosure, the swab stick applicator may be irregularly shaped to be more conducive to the intended treatment site. The base 120 attaches, as described below, to the upper portion 106 of the swab stick handle 102. The swab stick applicator 104 also includes an applicator side portion 118 and an applicator top portion 122. In one aspect of the disclosure, the applicator top portion 122 includes a flat shape and the applicator side portion 118 includes a rounded shape. As described above with reference to the swab stick handle 102, the swab stick applicator 104 may have a plurality of applicator side portions 118 and a plurality of applicator top portions 122 based upon the shape. The transition between the applicator side portion 118 and the applicator top portion 122 may be smooth or may be squared (for example, including a sharp edge). One or more of the applicator top portion 122 and the applicator side portion 118 may have one or more indentations in the surface thereof, preferably one indentation substantially centered in the applicator top portion 122 and / or in the applicator side portion 118 (for example, as shown in Figure 4).

[0052] The swab stick applicator 104 may be affixed to the swab stick handle 102 via adhesive or co-molding. For example, cyanoacrylate adhesives may be used to affix swab stick applicator 104 to the swab stick handle 102. Other suitable adhesives are known in the art.

[0053] The shape of the applicator allows application of the contact solution to an area of the body of a patient and also absorbs and / or releases sufficient volume to support clinical efficacy in accordance with the FDA Final Monograph (United States Food and Drug Administration (FDA) Final Rule for Topical Antimicrobial Drug Products for Over-the- Counter Human Use; Tentative Final Monograph for Healthcare Antiseptic Drug Products (Vol. 82, No. 143; 10 Dec 2017; pp 60474 60503), incorporated by reference herein in its entity.

[0054] As described above, the swab stick applicator 104 may be constructed of foam and is compatible with aqueous or alcoholic antiseptic solutions, sterilization modality, and also absorbs and releases a sufficient volume of solution to have clinical efficacy. In one aspect of the disclosure, the swab stick applicator 104 may be impregnated with a contact solution, as described above.

[0055] As described above, FIGS. 2-5 provide additional views illustrating the preferred swab stick, as described with reference to FIG. 1.
