[0048] II. Detailed Examples

[0049] Figure 1 An example of a system and apparatus according to aspects of this disclosure is shown. Preparation apparatus 100 may include an applicator or sponge 135 (hereinafter interchangeably referred to as an absorbent applicator). The sponge may be formed, for example, from any one or combination of rayon, polyester, cotton, polyurethane, polyurethane / polyester blends, polystyrene, polyethylene, or any other material suitable for use as a solution applicator. As in Figure 1 As illustrated in the example, the sponge 135 may be attached to or otherwise secured to the applicator body. The applicator body 110 may, for example, include an applicator body wall 108. The applicator body wall 108 may be configured to contain a solution and / or may be configured to allow a plunger to advance therein, as explained in further detail below. For example, the applicator body wall 108 may be in a substantially hollow cylindrical shape, having cavities therein, and having a sponge interface wall 107 at its distal end. The sponge interface wall may have one or more channels (e.g., indicated by arrow 102) at its distal end 107a that provide flow paths or fluid communication with the internal portion of the applicator body, which can serve as channels for containing a solution within the applicator body 110 to impregnate, infuse, saturate, and / or wet the sponge 135, thereby allowing the practitioner to administer the solution to the patient.

[0050] At the proximal end 107b of the preparation device 100, the applicator body 110 may have a plunger interface portion or handle 120 that passes through a wall or cap at the proximal end 107b of the applicator body 110. The applicator body 110 may be configured to have a plunger 122 slidably disposed therein, which is mechanically connected directly or indirectly to the handle 120 such that when pressure or force (e.g., in the direction PP) is applied to the handle 120, the plunger 122 moves (and transmits) the force applied to the handle 120. The plunger 122 may seal against or otherwise provide a sealing interface with the inner wall of the applicator body 110, such that the plunger 122 provides a barrier against the inner wall of the applicator body 110, sealing any fluid 114 (e.g., air, gas, and / or liquid) contained within the applicator body 110.

[0051] The preparation device 100 may further include or contain a solution-containing portion 111 within the applicator body 110. The solution-containing portion 111 may be, for example, a separately sealed ampoule, fragile component, or blister pack within the applicator body 110 containing a solution 114. The solution-containing portion 111 may be formed from the same material containing the solution (examples of solutions will be described in further detail below). Examples of suitable materials that can form the solution-containing portion 111 include, but are not limited to, polyolefins, polypropylene, polyethylene (e.g., high-density polyethylene, low-density polyethylene), ethylene / propylene copolymers, ethylene / butene copolymers, vinyl and vinyl polymers, acrylic polymers, polyesters (e.g., polyethylene terephthalate (PET), polybutylene terephthalate), polyvinyl alcohol, polyamide, polyvinyl chloride, polyvinylidene chloride, ethylene-vinyl alcohol, and any combination or mixture thereof. Fluorinated polymers or layers, such as trifluorochloroethylene, polytetrafluoroethylene (PTFE), trifluorochloroethylene, polyvinylidene fluoride, copolymers of perfluorinated monomers and partially fluorinated monomers, such as tetrafluoroethylene / hexafluoropropylene / vinylidene fluoride copolymers (e.g., THV fluorothermoplastics from Dyneon), and combinations thereof, can be used. In one embodiment, a blend of HDPE and polyamide can be used to form a single-layer container body. In some examples, the solution-containing portion 111 can be partially formed of a flexible or semi-flexible material having foil or aluminum foil portions configured to be torn or punctured when pressure is applied to the solution-containing portion 111 and / or when punctured by a structure configured to puncture the foil portions. Further, the solution-containing portion 111 can be formed of glass or a composite thereof. In some examples, the solution can be sealed within a portion of the applicator body 110 via a polymer film, aluminum foil or other foil, or a similar sealing system.

[0052] In some exemplary embodiments of this disclosure, the solution receiving portion 111 may be stored or otherwise housed within the applicator body 110 between the plunger 122 and the sponge interface wall 107. In some examples (explained in further detail below), the solution receiving portion 111 may be located between the plunger 122 and one or more puncture members 113. In one example, the solution receiving portion 111 may be connected to the plunger 122 or otherwise configured to contact the plunger and thus move linearly within the applicator body 110.

[0053] Solution 114 contained within solution containment portion 111 may be antimicrobial, meaning it is generally sterile to be free of pathogenic contaminants (e.g., bacteria, viruses, fungi, parasites, etc.). Antimicrobial conditions can be achieved by manufacturing in a controlled environment where contaminants are controlled, or by sterilizing the applicator after manufacturing (e.g., by exposure to ethylene oxide gas). The composition may also be an antimicrobial composition, incorporating an antimicrobial agent to allow its application to the treatment area to kill microorganisms and reduce the likelihood of infection. Therefore, the composition may be sterile and may also be antimicrobial. The composition may include any active substance or a selection from antimicrobial agents, antiviral agents, antimicrobial agents, and any combination thereof. For example, there are no particular limitations on the active substance contained in the composition, and it may be chlorhexidine or chlorhexidine salts, such as chlorhexidine gluconate, oxytinidin salt and / or hypochlorite solution, hypochlorous acid, sodium dodecyl sulfate, citric acid (aqueous solution), sodium citrate (aqueous solution), or benzalkonium chloride. Other active substances (such as povidone-iodine (PVP-I), iodine or other iodine complexes), and any other antimicrobial agents may also be used. Alcohols (such as methanol, ethanol, isopropanol, butanol, combinations thereof, etc.) may also be included. The composition may be a liquid. In some embodiments, two or more liquid components may be mixed and / or the liquid may be mixed with solid, gel, or other liquid components to produce a flowable liquid composition.

[0054] The composition may include dyes or colorants to provide color (e.g., red, purple, green, etc.) into the composition to contrast with the skin or other treatment area to which the composition is to be applied and / or to indicate coverage of the patient's skin or other areas.

[0055] The solution reservoir 111 can be configured to puncture, break, or rupture when force is applied to the solution reservoir 111 via the plunger 122 when a force is applied to the handle 120 (e.g., in the direction indicated by arrow PP). For example, the solution reservoir 111 may have a weakened portion or a portion designed to burst or open when a predetermined pressure or pressure range is applied thereto. As described above, the preparation device 100 may further include one or more puncture members 113 within the applicator body 110. One or more puncture members 113 can be configured to puncture or otherwise tear and / or break the solution reservoir 111 when it is pressed against one or more puncture members 113. Thus, once the solution reservoir 111 is punctured and / or destroyed, the solution contained therein can pass through one or more channels 102 and wet or soak / saturate the sponge 135. Once the solution-containing portion 111 ruptures, the user can further advance the handle 120 in the direction PP, thereby advancing the plunger 122 and applying pressure to the solution within the applicator body 110 to pressurize the solution and force it to saturate the sponge 135 and / or force it from the sponge 135 to the area to be treated. Therefore, even if the sponge 135 and / or the area where the practitioner wishes to apply the solution is higher than the solution in the applicator body 110, the solution can still be dispensed to the sponge 135 through the opening or channel 102.

[0056] In some examples, the applicator body 110 may include a filter 101 and / or a one-way valve or diaphragm. The filter 101 may prevent any debris from the ruptured solution receiving portion 111 from clogging or passing through the opening 102, and / or may limit the flow through the opening 102 to limit the flow rate of fluid through the opening 102, or otherwise prevent excessive solution from being forced through the opening 102 due to excessive force applied by the operator to the handle 120. Furthermore, as described above, a one-way valve may be implemented in conjunction with or as an alternative to the filter to prevent any fluid from flowing back from the sponge 135 into the applicator body 110, which can prevent solution contamination within the applicator body 110. The filter 101 may, for example, consist of one or more porous membranes and / or microporous membranes.

[0057] The applicator body 110 may further include one or more puncture members 113 for puncturing, breaking, or otherwise releasing the solution 114 within the solution containment portion 111 into the applicator body 110. The one or more puncture members 113 may be, for example, pointed or thorn-like. In some examples, the one or more puncture members 113 may be shaped like blades. The one or more puncture members 113 may be formed of any suitable material, including but not limited to any or a combination of metals, plastics, and / or semi-rigid or rigid rubbers, to name just a few. As described above, the one or more puncture members 113 may correspond to a weakened or reduced-strength portion of the solution containment portion 111, or may be positioned specifically to contact that portion. For example, the one or more puncture members 113 may be positioned to contact (and puncture) a sealing or foil (e.g., aluminum foil) portion of the solution containment portion 111. One or more puncture components 113 may be mounted, for example, to the sponge interface wall 107 (see, for example, sponge interface wall mount 113a) and / or the sidewall of the applicator body 110 (see, for example, wall interface mount 113b).

[0058] The preparation device 100 may further include a one-way feature that locks the plunger 122 when the operator presses the handle 120 and advances the plunger 122 during use. The one-way feature allows the plunger 122 to be advanced along the direction PP and can lock or otherwise prevent movement of the plunger 122 in a direction opposite to the direction PP. The one-way feature can gradually lock the plunger 122, thus ensuring that the plunger does not retract (i.e., move in a direction opposite to the direction PP) causing an unexpected drop in pressure of the solution within the applicator body 110. Furthermore, the aforementioned one-way feature can reduce operator stress by dispensing the solution without requiring the operator to apply constant pressure to the handle 120. Figure 1 A non-limiting example of the unidirectional feature 112 is shown, which may be, for example, a series of grooves or protrusions on the inner sidewall surface of the applicator body 110, configured to engage with corresponding grooves or protrusions 123 on the plunger 122. In one example, the grooves and / or protrusions may be barbed and / or include ramps on a first side and steps on a second side, allowing easy advance of the plunger 122 in the direction PP (i.e., via the ramps) while preventing the plunger 122 from easily retracting in a direction opposite to the direction PP (i.e., once engaged with the step portion).

[0059] The applicator body 110 can be formed of any suitable material. Some non-limiting examples include any or a combination of polyethylene terephthalate (PET or PETE), high-density polyethylene (HDPE), polyvinyl chloride (PVC), polypropylene (PP), and / or even glass or ceramic. In some examples, the applicator body 110 may be transparent, translucent, or semi-transparent to allow the practitioner to quickly identify whether the solution-containing portion 111 has been properly punctured and / or destroyed, and / or to see how much solution remains in the applicator body 110. In some cases, the applicator body 110 may include measuring markers to indicate to the practitioner how much solution has been dispensed.

[0060] Figure 2 Another example of a preparation device 200 according to various aspects of this disclosure is shown. Device 200 can be used with... Figure 1 Preparation device 100 in Figure 3 Preparation device 300 in Figure 4 The preparation device 400 and / or Figure 5 The preparation device 500 in the middle shares any or more features or may be similar to them. Figure 2 Example devices include extension rods for preparing cavities, body cavities, or surgical cavities, to name only a few non-limiting examples. Figure 2 The device 200 may include a rod having a distal end 232a and a proximal end 232b. In addition, the device 200 may include a sponge 230 (hereinafter interchangeably referred to as a treatment sponge) located at the distal end of the rod 232. Figure 2 The applicator body 210 of the device 200 can be in fluid communication with the rod 232, and the rod 232 can have internal channels to guide the solution from the applicator body 110 to the sponge 230 (e.g., as shown in the image). Figure 2 (As indicated by dashed arrow 229 in the diagram). The distal end of rod 232a may, for example, have one or more fluid passages 231 (e.g., a series of openings or other channels) to allow solution to permeate or infuse sponge 230 due to pressure applied by the operator (i.e., applied via handle 220 to advance plunger 222 toward interface wall 207). In an alternative example, rod 232 and / or solution container applicator portion 210 may be separate components from sponge 230. In another alternative example, rod 232 and applicator portion 210 may be a single, integral (i.e., not separate) component. Rod 232 may be inserted into sponge 230 to supply solution contained in solution container 220 to sponge 230.

[0061] Sponge 230 may be formed, for example, from any one or combination of rayon, polyester fiber, cotton, polyurethane, polyurethane / polyester blend, polystyrene, polyethylene, or any other material suitable for use as a solution applicator.

[0062] The applicator body wall 208 may be configured to contain a solution and / or may be configured to have a plunger propelled therein, as explained in further detail below. For example, the applicator body wall 208 may be substantially hollow cylindrical in shape, having a sponge interface wall 207 at its distal end. The sponge interface wall may have one or more channels 202 at its distal end, providing fluid communication or a fluid path to the internal portion of the applicator body 210, which may serve as channels for the solution contained within the applicator body 110 to flow through the rod 232 and through the channels at the sponge 230 to saturate, impregnate, infuse, and / or wet the sponge 230, thereby allowing the practitioner to apply the solution to the patient.

[0063] At the proximal end of the preparation device 200, the applicator body 210 may have a plunger interface portion or a handle 220 that passes through a wall or cap at the proximal end of the applicator body 210. The applicator body 210 may be configured to have a plunger 222 slidably disposed therein, which is mechanically connected directly or indirectly to the handle 220, such that when pressure or force (e.g., along) is applied... Figure 1 When the direction PP is applied to the handle 220 as shown, the plunger 222 moves (and transmits the force applied to the handle 120). The plunger 222 may seal against the inner wall of the applicator body 210, or otherwise provide a sealing interface with the inner wall, such that the plunger 222 provides a barrier to seal any fluid 214 (e.g., air, gas, and / or liquid) contained within the applicator body 210 together with the inner wall of the applicator body 210, and allows pressure to be applied to any fluid therein by pressing the handle 220.

[0064] The preparation device 200 may further include or house a solution containment portion 211 within the applicator body 210. The solution containment portion 211 may, for example, be a separately sealed ampoule, fragile component, or blister pack within the applicator body 210. The solution containment portion 211 may be formed from a single piece of material containing the solution (examples of solutions will be described in more detail below). Examples of suitable materials that can form the solution containment portion 211 include, but are not limited to, those described above. Figure 1 Example provided.

[0065] In some examples, the solution receiving portion 211 may be stored or otherwise housed within the applicator body 210 between the plunger 222 and the sponge interface wall 207. In some examples (explained in further detail below), the solution receiving portion 211 may be located between the plunger 222 and one or more puncture members 213. In one example, the solution receiving portion 211 may be connected to or otherwise configured to contact the applicator body 210 and thus move linearly within the applicator body together with the plunger 222.

[0066] The solution contained in the solution containing portion 211 can be as described above. Figure 1 The solution may contain any one or a combination thereof, and may also include dyes or colorants as described above.

[0067] When the user applies force to the handle 220, the solution reservoir 211 can be configured to puncture, break, or rupture upon application of force via the plunger 222. For example, the solution reservoir 211 may have a weakened portion or a portion intended to burst or open when a predetermined pressure or pressure range is applied thereto. The preparation device 200 may further include one or more puncture members 213 within the applicator body 210. When the solution reservoir 211 is pressed against one or more puncture members 213, the one or more puncture members 213 can be configured to puncture or otherwise tear and / or break the solution reservoir 211. Thus, once the solution reservoir 211 is punctured and / or destroyed, the solution contained therein can pass through the rod 232 and wet / saturate or soak into the sponge 230. Once the solution reservoir 211 is destroyed or punctured, the user can further advance the handle 220 in the PP direction, thus advancing the plunger 222 (…). Figure 1 The solution is pressurized within the applicator body 210 to compress it and force it to saturate or soak into the sponge 230. Therefore, even if the sponge 230 and / or the area where the practitioner wishes to apply the solution is higher than the solution in the applicator body 210, the solution can still be dispensed onto the sponge 230.

[0068] In some examples, the applicator body 210 may include a filter 201 and / or a one-way valve or diaphragm. The filter 201 may prevent any debris from the ruptured solution-containing section 211 from clogging or passing through the rod 232, and / or may limit the flow through the rod 232 to restrict the fluid velocity, or prevent excessive solution from being forced into the sponge 230 due to excessive force applied by the operator to the handle 220. Furthermore, as described above, a one-way valve may be implemented in conjunction with or as an alternative to the filter to prevent any fluid from flowing back from the sponge 230 and / or the rod 232 into the applicator body 210, which can prevent solution contamination within the applicator body 210. The filter may, for example, consist of one or more porous membranes and / or microporous membranes.

[0069] The applicator body 210 may further include one or more piercing members 213 for piercing, breaking, or otherwise releasing the solution within the solution containment portion 211 into the applicator body 210. The one or more piercing members 213 may be, for example, pointed or thorn-like. In some examples, the one or more piercing members 213 may be shaped like blades. The one or more piercing members 213 may be formed from any suitable material, non-limiting examples of which are referred to above. Figure 1 As described above, one or more puncture members 213 may correspond to a weakened or reduced-strength portion of the solution-containing portion 211, or may be positioned specifically to contact that portion. For example, one or more puncture members 213 may be positioned to contact (and puncture) the foil portion of the solution-containing portion 211. One or more puncture members 213 may be mounted, for example, to the sponge interface wall 207 via the wall mounting portion 213a and / or to the sidewall of the applicator body 210 via the sidewall mounting portion 213b.

[0070] The preparation device 200 may further include a one-way feature that locks the plunger 222 when the operator presses the handle 220 and advances the plunger 222 during use. The one-way feature allows for movement along the direction PP (…). Figure 1 The plunger 222 is advanced and can be locked or otherwise prevented from moving in the direction opposite to the direction PP. This one-way feature allows the plunger 222 to be gradually locked, thus ensuring that the plunger does not retract (i.e., move in the direction opposite to PP), causing an unexpected drop in pressure within the applicator body 210. Furthermore, this one-way feature reduces operator stress by dispensing solution without requiring the operator to apply constant pressure to the handle 220. Figure 2 A non-limiting example of a series of unidirectional features 212 is shown, which may be, for example, a groove or protrusion on the inner wall surface of the applicator body 210, configured to engage with a corresponding groove or protrusion 223 on the plunger 222. In one example, the groove and / or protrusion may be barbed and / or include a ramp on a first side and a step on a second side, allowing easy advance of the plunger 222 in the direction PP (i.e., via the ramp) while preventing the plunger 222 from easily retracting in a direction opposite to the direction PP (i.e., once engaged with the step portion).

[0071] The applicator body 210 can be formed from any suitable material. (The above is in conjunction with...) Figure 1Some non-limiting examples of materials are described. In some examples, the applicator body 210 may be clear or translucent to allow the practitioner to quickly identify whether the solution-containing portion 211 has been properly punctured and / or destroyed, and / or to see how much solution remains in the applicator body 210. In some cases, the applicator body 210 may include measuring markers to indicate to the practitioner how much solution has been dispensed.

[0072] Figure 3 An example of a system and apparatus according to various aspects of this disclosure is shown. The apparatus 300 described below can be used with... Figure 1 Preparation device 100 in Figure 2 Preparation device 200 in Figure 4 The preparation device 400 and / or Figure 5 The preparation device 500 in the process shares any or more features or may be similar to them. As described in further detail below, Figure 3 The preparation apparatus 300 shown may include two or more solution-containing portions 311a and / or 311b.

[0073] Figure 3 The preparation device 300 may include an applicator or sponge 335 (hereinafter interchangeably referred to as an absorbent applicator). The sponge may, for example, be made of the material described above. Figure 1 and Figure 2 Formed by any one or combination of the aforementioned materials. For example... Figure 3 As illustrated in the example, the sponge 335 may be attached to or otherwise secured to the applicator body. The applicator body 310 may, for example, include an applicator body wall 308. The applicator body wall 308 may be configured to contain a solution and / or may be configured to advance a plunger therein, as explained in further detail below. For example, the applicator body wall 308 may be in the shape of a substantially hollow cylinder with a sponge interface wall 307 at its distal end. The applicator body wall may form a cavity for containing a solution-containing portion and / or a solution. The sponge interface wall may have one or more channels (e.g., indicated by arrow 302) at its distal end 309a that provide fluid communication or flow path to an internal portion of the applicator body, which may serve as a channel for the solution contained within the applicator body 310 to impregnate, saturate, infuse, and / or wet the sponge 335, thereby allowing the practitioner to apply the solution to the patient.

[0074] At the proximal end 309b of the preparation device 300, the applicator body 310 may have a plunger interface portion or a handle 320 passing through a wall or cap at the proximal end 309b of the applicator body 310. The applicator body 310 may be configured to have a plunger 322 slidably disposed therein, which is mechanically connected directly or indirectly to the handle 320 such that when pressure or force (e.g., in the direction PP) is applied to the handle 320, the plunger 322 moves (and transmits the force applied to the handle 320). The plunger 322 may seal against the inner wall of the applicator body 310, or otherwise provide a sealing interface with the wall, such that the plunger 322 provides a barrier that, together with the inner wall of the applicator body 310, seals any fluid 314 (e.g., air, gas, and / or liquid) contained within the applicator body 310, and allows pressure to be applied to any fluid therein by pressing the handle 320.

[0075] The preparation device 300 may further include or house two or more solution-containing portions 311a and / or 311b within the applicator body 310. Each of the solution-containing portions 311a and / or 311b may be, for example, a separately sealed ampoule, fragile component, or blister pack within the applicator body 310. Each and / or any of the solution-containing portions 311a and / or 311b may be made from a single piece of material containing the solution (examples of solutions will be described in detail below). In some examples, the first solution-containing portion 311a may contain a different solution than the second solution-containing portion 311b. Furthermore, the first solution-containing portion 311a and / or the second solution-containing portion may be formed from the same or different materials.

[0076] Examples of suitable materials that can form any one or both of the solution containment portions 311a and / or 311b include, but are not limited to, polyolefins, polypropylene, polyethylene (e.g., high-density polyethylene, low-density polyethylene), ethylene / propylene copolymers, ethylene / butene copolymers, vinyl and vinyl polymers, acrylic polymers, polyesters (e.g., polyethylene terephthalate (PET), polybutylene terephthalate), polyvinyl alcohol, polyamides, polyvinyl chloride, polyvinylidene chloride, ethylene-vinyl alcohol, and any combination or mixture thereof. Fluorinated polymers or layers may be used, such as trifluorochloroethylene, polytetrafluoroethylene (PTFE), trifluorochloroethane, polyvinylidene fluoride, copolymers of perfluorinated monomers and partially fluorinated monomers, such as copolymers of tetrafluoroethylene / hexafluoropropylene / ethyleneene (e.g., Dyneon's THV thermoplastic fluoroplastics), and combinations thereof. Mixtures of HDPE and polyamides may be used to form a single-layer container body. In some examples, either or both of the solution containing portions 311a and / or 311b may be partially formed of a flexible or semi-flexible material having foil or aluminum foil portions that are torn or punctured when pressure is applied to either or both of the containing portions 311a-311b, and / or when a structure configured to puncture the foil portions is used. Furthermore, either or both of the solution containing portions 311a and / or 311b may be formed of glass or a composite material thereof. In some examples, two separate solutions may be sealed within a portion of the applicator body 310 via a polymer film, foil (e.g., aluminum foil), or a similar sealing system.

[0077] In some examples, solution receiving portions 311a and / or 311b may be stored or otherwise housed within the applicator body 310 between the plunger 322 and the sponge interface wall 307. Furthermore, for example (explained in further detail below), solution receiving portions 311a and / or 311b may be located between the plunger 322 and one or more puncture members 313a and / or 313b. In one example, solution receiving portions 311a and / or 311b may be connected to or otherwise configured to contact the applicator body 310 and thus move linearly within the applicator body together with the plunger 322.

[0078] As described above, the first solution receiving portion 311a and the second solution receiving portion 311b can contain different solutions. In some examples, the two solutions can be configured to mix within the applicator body 310, which can provide a solution that provides advantage for preparation. In another example, the applicator body 310 may include two separate chambers having two corresponding plungers or plunger halves. This is achieved by pressing with the first half-handle portion 320a. Figure 3The first half of the handle 320, shown by the dashed line, can individually dispense each solution (e.g., the solution in the first receiving portion 311a can be dispensed first) for initial preparation. Subsequently, by pressing the second half of the handle 320b, the second solution contained in the second solution receiving portion 311b can be dispensed.

[0079] While any suitable solution may be contained within one or both of the solution containing portions 311a and / or 311b, some examples may include sterile solutions, meaning they are typically sterilized and thus free of pathogenic contaminants (e.g., bacteria, viruses, fungi, parasites, etc.). Sterile conditions can be achieved by manufacturing in a controlled environment where contaminants are controlled, or by sterilizing the applicator after manufacturing (e.g., by exposure to ethylene oxide gas). The composition may also be an antiseptic composition containing a preservative, thereby allowing its application to kill microorganisms and reduce the likelihood of infection. Therefore, the composition can be sterile or antiseptic. The composition may include any active substance or a selection from antimicrobial agents, antiviral agents, preservatives, and any combination thereof. For example, there are no particular limitations on the active substance contained in the composition, and it may be chlorhexidine or chlorhexidine salts, such as chlorhexidine gluconate, octenamine salt and / or hypochlorite solutions, hypochlorous acid, sodium dodecyl sulfate, citric acid (aqueous), sodium citrate (aqueous), or benzalkonium chloride. Other active substances may also be used (e.g., povidone-iodine (PVP-I), iodine or other iodine complexes, and any other antimicrobial agents). Alcohols (e.g., methanol, ethanol, isopropanol, butanol, combinations thereof, etc.) may also be included. The composition may be a liquid. In some embodiments, two or more liquid components may be mixed and / or the liquid may be mixed with solid, gel, or other liquid components to produce a flowable liquid composition.

[0080] The above-described compositions may contain dyes or colorants to provide color to the composition (e.g., red, purple, green, etc.) to contrast with and / or indicate coverage on the patient's skin or other treatment area to which the composition will be applied. As described above, solution-containing portions 311a and / or 311b may include dyes of different colors, some of which are non-limiting examples provided above. In one example, either solution-containing portion 311a or 311b may contain a dye configured to mix with a solution in the other solution-containing portion.

[0081] One or both of the solution-containing portions 311a and / or 311b can be configured to puncture, break, or rupture when force is applied to the handle 320 (or the corresponding half of the plunger / handle in the above example) via the plunger 322. For example, the solution-containing portions 311a and / or 311b may have weakened portions or portions intended to burst or open when a predetermined pressure or pressure range is applied. The preparation device 300 may further include one or more puncture members 313a and / or 311b within the applicator body 310. One or more puncture members 313a and / or 311b can be configured to puncture or otherwise tear and / or break open the solution-containing portions 311a and / or 311b when the respective solution-containing portions 311a and / or 311b are pressed against the corresponding one of the puncture members 313a and / or 311b. Therefore, once the solution-containing portions 311a and / or 311b are punctured and / or damaged, the solution contained therein can pass through one or more channels 302 and saturate or wet / soak into the sponge 335. Once any or a combination of the solution-containing portions 311a and / or 311b is ruptured, the user can further advance the handle 320 in the direction PPP, thus advancing the plunger 322 and applying pressure to the solution within the applicator body 310 to pressurize the solution and force it to soak into the sponge 335. Thus, even if the sponge 335 and / or the area where the practitioner wishes to apply the solution is higher than the solution in the applicator body 310, the solution can still be dispensed into the sponge 335 through the openings or channels 302.

[0082] In some examples, the applicator body 310 may include a filter 301 and / or a one-way valve or diaphragm. The filter 301 may prevent any debris from the ruptured solution receiving portions 311a and / or 311b from clogging or passing through the opening 302, and / or may limit the flow through the opening 302 to limit the flow rate of fluid through the opening 302, or prevent excessive solution from being forced through the opening 302 due to excessive force applied by the operator to the handle 320. Furthermore, as described above, a one-way valve may be implemented in conjunction with or as an alternative to the filter to prevent any fluid from flowing back from the sponge 335 into the applicator body 310, which can prevent solution contamination within the applicator body 310. The filter may, for example, consist of one or more porous membranes and / or microporous membranes.

[0083] The applicator body 310 may further include one or more piercing members 313a and / or 313b for piercing, breaking, or otherwise releasing solution from the solution-containing portions 311 and / or 311b into the applicator body 310. One or more of the piercing members 313a and / or 313b may be, for example, pointed or thorn-like. In some examples, one or more piercing members 313a and / or 313b may be shaped like blades. One or more piercing members 313a and / or 313b may be formed of any suitable material, including but not limited to any or a combination of metals, plastics, and / or semi-rigid or rigid rubbers, to name just a few. As described above, one or more piercing members 313a and / or 313b may correspond to, or be positioned specifically to contact, a weakened or reduced-strength portion of the solution-containing portions 311a and / or 311b. For example, one or more puncture members 313a and / or 313b can be positioned to contact (and puncture) the foil portion of the corresponding solution containment portion 311a and / or 311b. One or more puncture members 313a and / or 313b can, for example, be mounted to the sponge interface wall 307 and / or the sidewall of the applicator body 310 (e.g., Figure 3 The elements not shown are for preventing obstruction of view, but are shown as the aforementioned sponge interface wall mounts 113a and / or 213a and wall interface mounts 113b and / or 213b.

[0084] The preparation device 300 may further include a one-way feature that locks the plunger 322 (and / or the corresponding half-plunger as described above) when the operator presses the handle 320 (or either 320a and / or 310b) and advances the plunger 322 during use. The one-way feature allows the plunger 322 or the aforementioned half-plunger to advance in the PPP direction and can lock or otherwise prevent movement of the plunger 322 in a direction opposite to the PPP direction. The one-way feature can gradually lock the plunger 322, thereby ensuring that the plunger does not retract (i.e., move in a direction opposite to the PPP direction), resulting in an unintended decrease in solution pressure within the applicator body 310. Furthermore, the aforementioned one-way feature reduces the operator's workload by dispensing the solution without requiring the operator to apply constant pressure to the handle 320. Figure 3A non-limiting example of the one-way feature 312 is shown. For example, the one-way feature may be a groove or protrusion on the inner wall surface of the applicator body 310, configured to engage with a corresponding groove or protrusion 323 on the plunger 322. In one example, the groove and / or protrusion may be barbed and / or include a ramp on a first side and a step on a second side, allowing the plunger 322 to be easily advanced in the PPP direction (i.e., via the ramp) while not allowing the plunger 322 to be easily retracted in a direction opposite to the PP direction (i.e., once engaged with the step portion).

[0085] The applicator body 310 can be formed from any suitable material. (The above is in conjunction with...) Figure 1 Some non-limiting examples are described. In some examples, the applicator body 310 may be clear or translucent to allow the practitioner to quickly identify whether the solution containing portions 311a and / or 311b have been properly punctured and / or destroyed, and / or to see how much solution remains in the applicator body 310. In some cases, the applicator body 310 may include measuring markers to indicate to the practitioner how much solution has been dispensed.

[0086] Figure 4 Another example of a system and apparatus according to aspects of this disclosure is shown. The apparatus 400 described below can be used with... Figure 1 Preparation device 100 in Figure 2 Preparation device 200 in Figure 3 The preparation device 300 and / or Figure 5 The preparation device 500 in the text shares one or more features, or may be similar to them. As described in further detail below, Figure 4 The preparation device 400 shown may include a spring or other biasing member 480 for activating or otherwise puncturing or breaking the solution receiving portion 411 and / or for applying pressure to the solution within the applicator body 410 (thereby dispensing the solution through the sponge 435).

[0087] Figure 4 The preparation device 400 may include an applicator or sponge 335 (hereinafter interchangeably referred to as an absorbent applicator). For example, the sponge may be made from the material described above. Figures 1-3 Formed from any one of the materials or combinations thereof. For example... Figure 4As illustrated in the example, the sponge 435 may be attached to or otherwise secured to the applicator body. The applicator body 410 may, for example, include an applicator body wall 408. The applicator body wall 408 may be configured to contain a solution and / or may be configured to allow a plunger to be advanced therein, as explained in further detail below. For example, the applicator body wall 408 may be substantially hollow cylindrical in shape, having cavities and a sponge interface wall 407 at its distal end. The sponge interface wall may have one or more channels (e.g., indicated by arrow 402) at its distal end 309a, which provide flow paths or fluid communication with an internal portion of the applicator body that may serve as channels for the solution contained within the applicator body 410 to saturate, impregnate, infuse, and / or wet the sponge 435, thereby allowing the practitioner to apply the solution to the patient.

[0088] At the proximal end 409b of the preparation device 400, the applicator body 310 may have a plunger interface portion or handle 320 that passes through a wall or cap at the proximal end 409b of the applicator body 410. The applicator body 410 may be configured to have a plunger 422 slidably disposed therein, which is mechanically connected directly or indirectly to the handle 420 such that when pressure or force (e.g., rotational force RR and / or pressing force PPPP) is applied to the handle 320, the plunger 322 moves (and transmits) the force applied to the handle 320. In one example, the applicator body 410 may house a biasing member or spring 480 configured to apply force in the PPPP direction. The biasing member or spring 480 may be positioned, for example, in a compressed or semi-compressed state, and a release mechanism may include or otherwise provide a reaction force to prevent the biasing member of the spring 480 from causing puncture and / or damage to the solution receiving portion 411 until the handle 420 is rotated in the RR direction. For example, the release mechanism may include a first retaining feature as one or more protrusions 481 projecting from a portion of the inner wall of the applicator body 408. The protrusions 481 may be configured to engage within or otherwise interact with one or more second retaining features 482, as a groove connecting to or as part of the plunger 422. Thus, when the release mechanism is in the first or retaining state, the second retaining features 482 may engage with the protrusions 481 in a snap-fit ​​manner, preventing movement of the plunger 422 in the PPPP direction and providing a force opposite to that provided by the compression bias member 480. When the handle 420 is rotated (e.g., in the RR direction), the second retaining features 482 rotate out of the protrusions 481, which subsequently allows the plunger 422 to move freely or more freely in the PPPP direction. Therefore, once the handle 420 is rotated, the reaction force provided by the release mechanism is released, causing the biasing member 480 to move the plunger 422 in the PPPP direction. This then causes the plunger 422 to apply pressure to the solution receiving portion 411, which may cause the solution receiving portion 411 to break or otherwise puncture or tear, as described below, and / or also apply pressure to the solution within the solution receiving portion 411 to saturate, impregnate, infuse, and / or wet the sponge 435. This exemplary embodiment may be advantageous because once the practitioner applies the rotational or release force, the practitioner may no longer need to apply pressure to the handle 420. In some examples, if, for example, more solution is needed than that provided solely by the pressure of the spring 480, the practitioner may still be able to apply pressure to the handle 420.

[0089] The preparation device 400 may further include or house a solution container 411 within the applicator body 410. The solution container 411 may, for example, be a separately sealed ampoule, fragile component, or blister pack within the applicator body 410. The solution container 411 may be formed from a monolithic material containing the solution (examples of solutions will be described in more detail below). Examples of suitable materials for forming the solution container 411 include, but are not limited to, those described above. Figure 1-3 Examples provided. As described above, in some examples, the solution containment portion 411 may be partially formed of a flexible or semi-flexible material having a foil or aluminum foil portion configured to be torn or punctured when pressure is applied to the solution containment portion 411 and / or when a structure configured to puncture the foil portion is used. Furthermore, the solution containment portion 411 may be formed of glass or a composite material thereof. In some examples, the solution may be sealed within a portion of the applicator body 410 via a polymer film or aluminum foil or other foil or similar sealing system.

[0090] In some examples, the solution receiving portion 411 may be stored or otherwise housed within the applicator body 410 between the plunger 422 and the sponge interface wall 407. In some examples (explained in further detail below), the solution receiving portion 411 may be between the plunger 422 and one or more puncture members 413. In one example, the solution receiving portion 411 may be connected to or otherwise configured to contact the applicator body 410, thereby moving linearly within the applicator body together with the plunger 422.

[0091] The solution contained in the solution containing portion 411 can be as described above. Figures 1-3 The solution may contain any one or a combination thereof, and may further include dyes or colorants as described above.

[0092] When a user applies force to the handle 420, the solution reservoir 411 can be configured to puncture, break, or rupture upon application of force via the plunger 422. For example, the solution reservoir 411 may have a weakened portion or a portion otherwise designed to burst or open upon application of a predetermined pressure or pressure range. The preparation device 400 may further include one or more puncture members 413 within the applicator body 410. One or more puncture members 413 may be configured to puncture or otherwise tear and / or break the solution reservoir 411 when it is pressed against one or more puncture members 413. Thus, once the solution reservoir 411 is punctured and / or destroyed, the solution contained therein can pass through the channel 402 and wet or soak / saturate the sponge 430. Once the solution-containing portion 411 ruptures, the spring 480 can further advance the plunger 422 along the PPPP direction and apply pressure to the solution within the applicator body 410 to squeeze the solution and force it to soak into the sponge 435. Therefore, even if the sponge 435 and / or the area where the practitioner wishes to apply the solution is higher than the solution in the applicator body 410, the solution can still be dispensed onto the sponge 435. As described in the above example, the solution-containing portion 411 may include multiple separate solution-containing portions that contain multiple solutions configured to mix within the applicator body 410 upon rupture or puncture.

[0093] In some examples, the applicator body 410 may include a filter 401 and / or a one-way valve or diaphragm. The filter 401 may prevent any debris from the ruptured solution receiving portion 411 from clogging or passing through the channel 402, and / or may restrict flow through the channel 402 to limit the fluid flow rate, or otherwise prevent excessive solution from being forced into the sponge 435. Furthermore, as described above, the one-way valve may be implemented in conjunction with the filter or as an alternative to the filter to prevent any fluid from flowing back from the sponge 435 into the applicator body 410, which can prevent contamination of the solution within the applicator body 410. The filter may, for example, consist of one or more porous membranes and / or microporous membranes.

[0094] The applicator body 410 may further include one or more piercing members 413 for piercing, breaking, or otherwise releasing the solution within the solution containment portion 411 into the applicator body 410. The one or more piercing members 413 may be, for example, pointed or thorn-like. In some examples, the one or more piercing members 413 may be shaped like blades. The one or more piercing members 413 may be formed of any suitable material, non-limiting examples of which have been incorporated above. Figures 1-3As described above, one or more puncture members 413 may correspond to a weakened or reduced-strength portion of the solution-containing portion 411, or may be positioned specifically to contact such weakened or reduced-strength portion. For example, one or more puncture members 413 may be positioned to contact (and puncture) the foil portion of the solution-containing portion 411. One or more puncture members 413 may, for example, be mounted to the sponge interface wall 407 and / or the sidewall of the applicator body 410. Furthermore, as... Figure 3 As shown in the example, one or more puncture members 413 may correspond to a single solution-containing portion (e.g., 311a and / or 311b above).

[0095] The applicator body 410 can be formed from any suitable material. (The above is in conjunction with...) Figures 1-3 Some non-limiting examples of materials are described. In some examples, the applicator body 410 may be clear or translucent to allow the practitioner to quickly identify whether the solution receiving portion 411 has been properly punctured and / or broken, and / or to view the remaining solution in the applicator body 410. In some cases, the applicator body 410 may include measuring markers to indicate to the practitioner how much solution has been dispensed.

[0096] Figure 5 Another example of a system and apparatus according to aspects of this disclosure is shown. The apparatus 500 described below can be used with... Figure 1 Preparation device 100 in Figure 2 Preparation device 200 in Figure 3 The preparation device 300 and / or Figure 4 The preparation device 400 shares any one or more features, or may be similar. The preparation device 500 may include an applicator or sponge 535 (hereinafter interchangeably referred to as an absorbent applicator). The sponge may be formed, for example, from any one of the materials described above or a combination of the materials described above. Figure 5As illustrated in the example, the sponge 535 may be attached to or otherwise secured to the applicator body. The applicator body may include an applicator body wall configured to contain a solution and / or may be configured to have a pivot plunger or squeeze portion 521 therein for advancement (it should be noted that the terms squeeze portion and plunger are used interchangeably in this disclosure). For example, the shape of the applicator body wall may be substantially a hollow cylinder with cavities and a sponge interface wall 507 at its distal end. The sponge interface wall may have one or more channels (e.g., indicated by arrow 502) at its distal end 507a, which provide flow paths or fluid communication with an internal portion of the applicator body that may serve as channels for the solution contained within the applicator body 510 to saturate, impregnate, infuse, and / or wet the sponge 535, thereby allowing the practitioner to apply the solution to the patient.

[0097] At the proximal end 509b of the preparation device 500, the applicator body 110 may have a plunger interface portion or a handle 520 and / or an applicator body handle 575. The applicator body 510 may be configured to have a plunger 522 pivotally mounted (e.g., via a pivot portion 577) to the applicator body, the plunger being directly or indirectly mechanically connected to the handle 520 such that when pressure or force (e.g., along the RRR direction) is applied to the handle 520, the plunger 522 moves as a force RR (and transmits) the force applied to the handle 520. It is worth noting that the above and Figure 5 The pivot portion 577 shown in the example embodiment may be, for example, a mechanical pivot (i.e., having a shaft rotatably housed in one or more bushings) and / or may be a flexible material configured to elastically or plastically deform to allow the handle 520 to rotate about the pivot portion 577.

[0098] The preparation device 500 may further include or house a solution container 511 within the applicator body 510. The solution container 511 may be, for example, a separately sealed ampoule, fragile component, or blister pack within the applicator body 510. The solution container 511 may be formed from a monolithic material containing the solution (examples of solutions will be described in more detail below). Examples of suitable materials that can form the solution container 511 are described above. Figure 1 Provided as an example in the description.

[0099] In some examples, the solution receiving portion 511 may be stored or otherwise housed within the applicator body 510 between the plunger 522 and the sponge interface wall 507. In some examples (explained in further detail below), the solution receiving portion 511 may be between the plunger 522 and one or more puncture members 513. In one example, the solution receiving portion 511 may be connected to or otherwise configured to contact the applicator body 510, thereby moving together with the plunger 522 within the applicator body.

[0100] The solution contained in the solution containing portion 511 can be sterile, meaning it is typically disinfected to ensure it is free of pathogenic contaminants (e.g., bacteria, viruses, fungi, parasites, etc.). Sterile conditions can be achieved by manufacturing in a controlled environment where contaminants are controlled, or by sterilizing the applicator after manufacturing (e.g., by exposure to ethylene oxide gas). The composition can also be an antiseptic composition, including a preservative to kill microorganisms when applied to the treatment area, thereby reducing the likelihood of infection. Therefore, the composition can be either sterile or antiseptic. The composition can include any active substance or a selection from antimicrobial agents, antiviral agents, preservatives, and any combination thereof. For example, there are no particular limitations on the active substance included in the composition; it can be chlorhexidine or chlorhexidine salts, such as chlorhexidine gluconate, octenamine salt and / or hypochlorite solution, hypochlorous acid, sodium dodecyl sulfate, citric acid (aqueous), sodium citrate (aqueous), or benzalkonium chloride. Other active substances may also be used (e.g., povidone-iodine (PVP-I), iodine or other iodine complexes, and any other antimicrobial agents). Alcohols may also be included (e.g., methanol, ethanol, isopropanol, butanol, combinations thereof, etc.). The composition may be a liquid. In some embodiments, two or more liquid components may be mixed and / or the liquid may be mixed with a solid, gel, or other liquid component to produce a flowable liquid composition. Furthermore, as described above, the solution receiving portion 511 may have multiple chambers or may include multiple solution receiving portions configured to mix upon puncture, rupture, or fragmentation of the multiple solution receiving portions.

[0101] The composition may include dyes or colorants to provide color to the composition (e.g., red, purple, green, etc.) to contrast with the skin or other treatment area to which the composition will be applied and / or to indicate the coverage on the patient's skin or other treatment area.

[0102] When a user applies force to the handle 520, the solution reservoir 511 can be configured to puncture, rupture, or break when force is applied to the solution reservoir 511 via the plunger 522. For example, the solution reservoir 511 may have a weakened portion or a portion otherwise designed to burst or open when a predetermined pressure or pressure range is applied. The preparation device 500 may further include one or more puncture members 513 within the applicator body 510. When the solution reservoir 511 is pressed against one or more puncture members 513, one or more puncture members 513 can be configured to puncture or otherwise tear and / or break the solution reservoir 511. Thus, once the solution reservoir 511 is punctured and / or ruptured, the solution contained therein can pass through one or more channels 502 and wet or soak into / saturate the sponge 535. Once the solution-containing portion 511 breaks, the user can further advance the handle 520 along the RRR direction, thereby advancing the plunger 522 and applying pressure to the solution within the applicator body 510 to squeeze the solution and force it to soak into the sponge 535. Therefore, even if the sponge 535 and / or the area where the practitioner wishes to apply the solution is higher than the solution in the applicator body 510, the solution can still be dispensed to the sponge 535 through the opening or channel 502.

[0103] In some examples, the applicator body 510 may include a filter (e.g., Figure 5 Not shown in the text, but Figure 1 The image shown is displayed as filter 101. Figure 2 The value shown is 201. Figure 3 The value shown is 301. Figure 4 The filter is shown as 401) and / or a one-way valve or diaphragm. The filter can prevent any debris from the broken solution receiving portion from clogging or passing through the opening, and / or can restrict flow through the opening to limit the flow rate of fluid through opening 502, or otherwise prevent excessive solution from being forced through opening 502 due to excessive force applied by the operator to handle 520. Furthermore, as described above, a one-way valve can be implemented with or as an alternative to the filter to prevent any fluid from flowing back from sponge 535 to the applicator body 510, which can prevent contamination of the solution within the applicator body 510. The filter can, for example, consist of one or more porous membranes and / or microporous membranes.

[0104] The applicator body 510 may further include one or more piercing members 513 for piercing, breaking, or otherwise releasing the solution within the solution containment portion 511 into the applicator body 510. One or more piercing members 513 may be, for example, pointed or thorn-like. In some examples, one or more piercing members 513 may be shaped like blades. One or more piercing members 513 may be formed of any suitable material, including but not limited to any or a combination of metals, plastics, and / or semi-rigid or rigid rubber, to name just a few. As described above, one or more piercing members 513 may correspond to a weakened or reduced-strength portion of the solution containment portion 511, or may be positioned specifically to contact such weakened or reduced-strength portion. For example, one or more piercing members 513 may be positioned to contact (and pierce) the foil portion of the solution containment portion 511. One or more piercing members 513 may, for example, be mounted to the sponge interface wall 507 and / or sidewall 508 of the applicator body 510. Furthermore, as... Figure 3 As shown in the example, one or more puncture members 413 may correspond to a single solution-containing portion (e.g., 311a and / or 311b above).

[0105] The preparation device 500 may further include a one-way feature that locks the plunger 522 when the operator squeezes the handle 520 and advances the plunger 522 during use. The one-way feature allows the plunger 522 to advance in the RR direction and can lock or otherwise prevent the plunger 522 from moving in a direction opposite to RR. The one-way feature can gradually lock the plunger 522, thereby ensuring that the plunger does not retract (i.e., move in a direction opposite to RR), causing an unexpected decrease in the pressure of the solution within the applicator body 510. Furthermore, the aforementioned one-way feature reduces the operator's workload by dispensing the solution without requiring the operator to apply a constant squeezing pressure to the handle 520. Figure 5 A non-limiting example of the one-way feature 512 is shown. For example, the one-way feature may be a groove or protrusion on the inner wall surface of the applicator body 510, configured to engage with a corresponding groove or protrusion 523 on the plunger 522. In one example, the groove and / or protrusion may be barbed and / or include a ramp on a first side and a step on a second side, allowing the plunger 522 to be easily advanced in the RR direction (i.e., via the ramp) while not allowing the plunger 522 to be easily retracted in a direction opposite to the RR direction (i.e., once engaged with the step portion).

[0106] The applicator body 510 can be formed of any suitable material. Some non-limiting examples include any or a combination of polyethylene terephthalate (PET or PETE), high-density polyethylene (HDPE), polyvinyl chloride (PVC), polypropylene (PP), and / or even glass or ceramic. In some examples, the applicator body 510 may be clear or translucent to allow the practitioner to quickly identify whether the solution receiving portion 511 has been properly punctured and / or broken, and / or to view the remaining solution in the applicator body 510. In some cases, the applicator body 510 may include measuring markers to indicate to the practitioner how much solution has been dispensed.

[0107] It should be noted that while several examples have been provided above, those skilled in the art will understand that many alternative configurations have been considered and will become clear with the help of this disclosure. For example, the examples described above can be applied to multi-step preparation. For example, any one or a combination of the devices or aspects described above can be used to provide two or more solutions. For example, a first device can be used to provide a PVPI-I solution, and a second device can be used to provide a flushing solution, such as saline. In some examples, the first and second devices can be connected together or otherwise mechanically held together. In another aspect, the first and second devices can be packaged together with an applicator indicator or instructions.
